THE HAND IN THE DARK

CHAPTER I

Seen in the sad glamour of an English twilight, the old moat-house, emerging from the thin mists which veiled the green flats in which it stood, conveyed the impression of a habitation falling into senility, tired with centuries of existence. Houses grow old like the race of men; the process is not less inevitable, though slower; in both, decay is hastened by events as well as by the passage of Time.

The moat-house was not so old as English country-houses go, but it had aged quickly because of its past. There was a weird and bloody history attached to the place: an historical record of murders and stabbings and quarrels dating back to Saxon days, when a castle had stood on the spot, and every inch of the flat land had been drenched in the blood of serfs fighting under a Saxon tyrant against a Norman tyrant for the sacred catchword of Liberty.

The victorious Norman tyrant had killed the Saxon, taken his castle, and tyrannized over the serfs during his little day, until the greater tyrant, Death, had taught him his first—and last—lesson of humility. After his death some fresh usurper had pulled down his stolen castle, and built a moat-house on the site. During the next few hundred years there had been more fighting for restless ambition, invariably connected with the making and unmaking of tyrants, until an English king lost his head in the cause of Liberty, and the moat-house was destroyed by fire for the same glorious principle.

It was rebuilt by the freebooter who had burnt it down; one Philip Heredith, a descendant of Philip Here-Deith, whose name is inscribed in the Domesday Book as one of the knights of the army of Duke William which had assembled at Dives for the conquest of England. Philip Heredith, who was as great a fighter as his Norman ancestor, established his claim to his new estate, and avoided litigation concerning it, by confining the Royalist owner and his family within the walls of the moat-house before setting it on fire. He afterwards married and settled down in the new house with his young wife. But the honeymoon was disturbed by the ghost of the cavalier he had incinerated, who warned him that as he had founded his line in horror it would end in horror, and the house he had built would fall to the ground.

Philip Heredith, like many other great fighters, was an exceedingly pious man, with a profound belief in the efficacy of prayer. He endeavoured to thwart the ghost's curse by building a church in the moat-house grounds, where he spent his Sundays praying for the eternal welfare of the gentleman he had cut off in the flower of his manhood. Perhaps the prayers were heard, for, when Philip Heredith in the course of time became the first occupant of the brand-new vault he had built for himself and his successors, he left behind him much wealth, and a catalogue of his virtues in his own handwriting. The wealth he left to his heirs, but he expressly stipulated that the record of his virtues was to be carved in stone and placed as an enduring tablet, for the edification of future generations, inside the church he had built.

It was a wise precaution on his part. The dead are dumb as to their own merits, and the living think only of themselves. Time sped away, until the first of the Herediths was forgotten as completely as though he had never existed; even his dust had been crowded off the shelf of his own vault to make room for the numerous descendants of the prolific and prosperous line he had founded. But the tablet remained, and the old moat-house he had built still stood.

It was a wonderful old place and a delight to the eye, this mediæval moat-house of mellow brick, stone facings, high-pitched roof, with terraced gardens and encircling moat. It had defied Time better than its builder, albeit a little shakily, with signs of decrepitude here and there apparent in the crow's-feet cracks of the brickwork, and decay only too plainly visible in the crazy angles of the tiled roof. But the ivy which covered portions of the brickwork hid some of the ravages of age, and helped the moat-house to show a brave front to the world, a well-preserved survivor of an ornamental period in a commonplace and ugly generation.

The place looked as though it belonged to the past and the ghosts of the past. To cross the moat bridge was to step backward from the twentieth century into the seventeenth. The moss-grown moat walls enclosed an old-world garden, most jealously guarded by high yew hedges trimmed into fantastic shapes of birds and animals; a garden of parterres and lawns, where tritons blew stone horns, and naked nymphs bathed in marble fountains; with an ancient sundial on which the gay scapegrace Suckling had once scribbled a sonnet to a pair of blue eyes—a garden full of sequestered walks and hidden nooks where courtly cavaliers and bewitching dames in brocades and silks, patches and powder, had played at the great game of love in their day. That day was long since dead. The tritons and nymphs remained, to remind humanity that stone and marble are more durable than flesh and blood, but the lords and ladies had gone, never to return, unless, indeed, their spirits walked the garden in the white stillness of moonlit nights. They may well have done so. It was easy to imagine such light-hearted beauties visiting again the old garden to revive dead memories of love and laughter: shadowy forms stealing forth to assignations on the blanched, dew-laden lawn, their roguish faces and bright eyes—if ghosts have eyes—peeping out of ghostly hoods at gay ghostly cavaliers; coquetting and languishing behind ghostly fans; perhaps even feeding, with ghostly little hands, the peacocks which still kept the terrace walk above the moat.

The spectacle of a group of modern ladies laughing and chatting at tea in the cloistered recesses of the terrace garden struck a note as sharply incongruous as a flock of parrots chattering in a cathedral.

It was the autumn of 1918, and with one exception the ladies seated at the tea-tables on the lawn represented the new and independent type of womanhood called into existence by the national exigencies of war. The elder of them looked useful rather than beautiful, as befitted patriotic Englishwomen in war-time; the younger ones were pretty and charming, but they were all workers, or pretended workers, in the task of helping England win the war, and several of them wore the khaki or blue of active service abroad. They were all very much at ease, laughing and talking as they drank their tea and threw cake to the peacocks perched on the high terrace walk above their heads.

The ladies were the guests of Sir Philip Heredith. Some months before, his only son Philip, then holding a post in the War Office, had fallen in love with the pretty face of a girl employed in one of the departments of Whitehall. He married her soon afterwards, and brought her home to the moat-house. It was the young husband who had suggested that they should liven up the old moat-house by inviting some of their former London friends down to stay with them. Violet Heredith, who found herself bored with country life after the excitement of London war work, caught eagerly at the idea, and the majority of the ladies at tea were the former Whitehall acquaintances of the young wife, with whom she had shared matinée tickets and afternoon teas in London during the last winter of the war.

The hostess of the party, Miss Alethea Heredith, sister of the present baronet, Sir Philip Heredith, and mistress of the moat-house since the death of Lady Heredith, belonged to a bygone and almost extinct type of Englishwoman, the provincial great lady, local society leader, village patroness, sportswoman, and church-woman in one, a type exclusively English, taking several centuries to produce in its finished form. Miss Heredith was an excellent, if somewhat terrific, specimen of the class. She was tall and massive, with a large-boned face, tanned red with country air, shrewd grey eyes looking out beneath thick eyebrows which met across her forehead in a straight line (the Heredith eyebrows) and a strong, hooked nose (the Heredith falcon nose). But in spite of her massive frame, red face, hooked nose, and countrified attire, she looked more in place with the surroundings than the frailer and paler specimens of womanhood to whom she was dispensing tea. There was a stiff and stately grace in her movements, a slow ceremoniousness, in her politeness to her guests, which seemed to harmonize with the seventeenth-century setting of the moat-house garden.

At the moment the ladies were discussing an event which had been arranged for that night: a country drive, to be followed by a musical evening and dance. The invitations had been issued by the Weynes, a young couple who had recently made their home in the county. The husband was a popular novelist, who had left the distractions of London in order to win fame in peace and quietness in the country. Mrs. Weyne, who had been slightly acquainted with Mrs. Heredith before her marriage, was delighted to learn she was to have her for a neighbour. She had arranged the evening on her behalf, and had asked Miss Heredith to bring all her guests. The event was to mark the close of the house party, which was to break up on the following day. Unfortunately, Mrs. Heredith had fallen ill a few hours previously, and it was doubtful whether she would be able to join in the festivity.

"I hope you will all remember that dinner is to be a quarter of an hour earlier to-night," said Miss Heredith, as she handed a cup of tea to one of her guests. "It is a long drive to the Weynes' place, so I shall order the cars for half-past seven."

The guests glanced at their hostess and murmured polite assent.

"I am looking forward to the visit so much," said the lady to whom Miss Heredith had handed the cup. "It will be so romantic—a country dance in a lonely house on a hill. What an adorable cup, dear Miss Heredith! I love Chinese egg-shell porcelain, but this is simply beyond anything! It's——"

"Whatever induced Dolly Weyne to bury herself in the country?" abruptly exclaimed a young woman with cropped hair and khaki uniform. "She loathed the country before she was married."

"Mrs. Weyne is a wife, and it is her duty to like her husband's home," said Miss Heredith a little primly. She disapproved of the speaker, whose khaki uniform, close-cropped hair, crossed legs, and arms a-kimbo struck her as everything that was modern and unwomanly.

"Then what induced Teddy Weyne to bury himself alive in the wilds? I'm sure it must be terrible living up there alone, with nothing but earwigs and owls for company."

"Mr. Weyne is a writer," rejoined Miss Heredith. "He needs seclusion."

"My husband doesn't," said a little fair-haired woman. "He says newspaper men can write anywhere. And we know another writer, a Mr. Harland, I think his name is, who writes long articles in the Sunday newspapers——"

"I don't think his name is Harland, dear," interrupted another lady. "Something like it, but not Harland. Dear me, what is it?"

"Oh, the name doesn't matter," retorted her friend. "The point is that he writes long articles in his London office. Why can't Mr. Weyne do the same?"

"Mr. Weyne is a novelist—not a journalist. It's quite a different thing."

"Is it?" responded the other doubtfully. "All writing is the same, isn't it? Harry says Mr. Harland's articles are dreadfully clever. He sometimes reads bits of them to me."

"Mrs. Weyne feels a little lonely sometimes," said Miss Heredith. "She has been looking forward to meeting Violet again. It will be pleasant for both of them to renew their acquaintance."

"I should think she and Violet would get on well together," remarked the young lady with the short hair. "They both have a good many tastes in common. Neither likes the country, for one thing." The other ladies looked at one another, and the speaker, realizing that she had been tactless, stopped abruptly. "How is Violet?" she added lamely. "Do you think she will be well enough to go to-night?"

"I still hope she may be well enough to go," replied Miss Heredith. "I will ask her presently. Will anyone have another cup of tea?"

Nobody wanted any more tea. The meal was finished; but the groups of ladies at the little tables sat placidly talking, enjoying the peaceful surroundings and the afternoon sun. Some of the girls produced cigarette-cases, and lit cigarettes.

There was a sound of footsteps on the gravel walk. A tall, good-looking young officer was seen walking across the garden from the house. As he neared the tea-tables he smilingly raised a finger to his forehead in salute.

"I've come to say good-bye," he announced.

The ladies clustered around him. It was evident from their manner that he was a popular figure among them. Several of the younger girls addressed him as "Dick," and asked him to send them trophies from the front. The young officer held his own amongst them with laughing self-possession. When he had taken his farewell of them he approached Miss Heredith, and held out his hand with a deferential politeness which contrasted rather noticeably with the easy familiarity of his previous leave-taking.

"I am sorry you are compelled to leave us, Captain Nepcote," said Miss Heredith, rising with dignity to accept his outstretched hand. "Do you return immediately to the front?"

"To-night, I expect."

"I trust you will return safely to your native land before long, crowned with victory and glory."

Captain Nepcote bowed in some embarrassment. Like the rest of his generation, he was easily discomposed by fine words or any display of the finer feelings. He was about twenty-eight, of medium height, clean-shaven, with clear-cut features, brown hair, and blue eyes. At the first glance he conveyed nothing more than an impression of a handsome young English officer of the familiar type turned out in thousands during the war; but as he stood there talking, a sudden ray of sunlight falling on his bared head revealed vague lines in the face and a suspicion of silver in the closely cropped hair, suggesting something not altogether in keeping with his debonair appearance—secret trouble or dissipation, it was impossible to say which.

"Will you say good-bye to Mrs. Heredith for me?" he said, after a slight pause. "I hope she will soon be better. I have said good-bye to Sir Philip and Phil. Sir Philip wanted to drive me to the station, but I know something of the difficulties of getting petrol just now, and I wouldn't allow him. Awfully kind of him! Phil suggested walking down with me, but I thought it would be too much for him."

They had walked away from the tea-tables towards the bridge which spanned the entrance to the moat-house. Miss Heredith paused by two brass cannon, which stood on the lawn in a clump of ornamental foliage, with an inscription stating that they had been taken from the Passe-partout, a French vessel captured by Admiral Heredith in the Indian Seas in 1804.

"It is hard for Phil, a Heredith, to remain behind when all young Englishmen are fighting for their beloved land," she said softly, her eyes fixed upon these obsolete pieces of ordnance. "He comes of a line of great warriors. However," she went on, in a more resolute tone, "Phil has his duties to fulfil, in spite of his infirmity. We all have our duties, thank God. Good-bye, Captain Nepcote. I am keeping you, and you may miss your train."

"Good-bye, Miss Heredith. Thank you so much for your kindness during a very pleasant visit. I've enjoyed myself awfully."

"I am glad that you have enjoyed your stay. I hope you will come and see us again when your military duties permit."

"Er—yes. Thank you awfully. Thank you once more for your kindness."

The young officer uttered these polite platitudes of a guest's farewell with some abruptness, bowed once more, and turned away across the old stone bridge which spanned the moat.

CHAPTER II

Miss Heredith turned her steps towards the house. The guests had dispersed while she was saying farewell to Captain Nepcote, and nothing further was expected of her as a hostess until dinner-time. It was her daily custom to devote a portion of the time between tea and dinner to superintending the arrangements for the latter meal. The moat-house possessed a competent housekeeper and an excellent staff of servants, but Miss Heredith believed in seeing to things herself.

On her way to the house she caught sight of an under gardener clipping one of the ornamental terrace hedges on the south side of the house, and she crossed over to him. The man suspended his work as the great lady approached, and respectfully waited for her to speak.

"Thomas," said Miss Heredith, "go and tell Linton to have both motors and the carriage at the door by half-past seven this evening. And tell him, Thomas, that Platt had better drive the carriage."

The under gardener touched his cap and hastened away on his errand. Miss Heredith leisurely resumed her walk to the house, stopping occasionally to pluck up any weed which had the temerity to show its head in the trim flower-beds which dotted the wide expanse of lawn between the moat and the house. She entered the house through the porch door, and proceeded to the housekeeper's apartments.

Her knock at the door was answered by a very pretty girl, tall and dark, who flushed at the sight of Miss Heredith, and stood aside for her to enter. A middle-aged woman, with a careworn face and large grey eyes, dressed in black silk, was seated by the window sewing. She rose and came forward when she saw her visitor. She was Mrs. Rath, the housekeeper, and the pretty girl was her daughter.

"How are you, Hazel?" said Miss Heredith, offering her hand to the girl. "It is a long time since I saw you. Why have you not been to see us lately?"

The girl appeared embarrassed by the question. She hesitated, and then, as if reassured by Miss Heredith's gracious smile, murmured that she had been so busy that she had very little time to herself.

"I thought they gave you an afternoon off every week at your place of employment," pursued Miss Heredith, seating herself in a chair which the housekeeper placed for her.

"Not always," replied Hazel. "At least, not lately. We have had such a lot of orders in."

"Do you like the millinery business, Hazel?"

"Very much indeed, Miss Heredith."

"Hazel is getting on nicely now," said her mother.

"I am very glad to hear it," responded Miss Heredith, in the same gracious manner. "You must come and see us oftener. I take a great interest in your welfare, Hazel. Now, Mrs. Rath."

There are faces which attract attention by the expression of the eyes, and the housekeeper's was one of them. Her face was thin, almost meagre, with sunken temples on which her greying hair was braided, but her large eyes were unnaturally bright, and had a strange look, at once timid and watchful. She now turned them on Miss Heredith as though she feared a rebuke.

"Mrs. Rath," said Miss Heredith, "I hope dinner will be served punctually at a quarter to seven this evening, as I arranged. And did you speak to cook about the poultry? She certainly should get more variety into her cooking."

"It is rather difficult for her just now, with the food controller allowing such a small quantity of butcher's meat," observed Mrs. Rath. "She really does her best."

"She manages very well on the whole, but she has many resources, such as poultry and game, which are denied to most households."

When Miss Heredith emerged from the housekeeper's room a little later she was quite satisfied that the dinner was likely to be as good as an arbitrary food controller would permit, and she ascended to her room to dress. In less than half an hour she reappeared, a rustling and dignified figure in black silk. She walked slowly along the passage from her room, and knocked at Mrs. Heredith's door.

"Come in!" cried a faint feminine voice within.

Miss Heredith opened the door gently, and entered the room. It was a spacious and ancient bedroom, with panelled walls and moulded ceiling. The Jacobean furniture, antique mirrors, and bedstead with silken drapings were in keeping with the room.

A girl of delicate outline and slender frame was lying on the bed. She was wearing a fashionable rest gown of soft silk trimmed with gold embroidery, her fair hair partly covered by a silk boudoir cap. By her side stood a small table, on which were bottles of eau-de-Cologne and lavender water, smelling salts in cut glass and silver, a gold cigarette case, and an open novel.

The girl sat up as Miss Heredith entered, and put her hands mechanically to her hair. Her fingers were loaded with jewels, too numerous for good taste, and amongst the masses of rings on her left hand the dull gold of the wedding ring gleamed in sober contrast. Her face was pretty, but too insignificant to be beautiful. She had large blue eyes under arching dark brows, small, regular features, and a small mouth with a petulant droop of the under lip. Her face was of the type which instantly attracts masculine attention. There was the lure of sex in the depths of the blue eyes, and provocativeness in the drooping lines of the petulant, slightly parted lips. There was a suggestion of meretriciousness in the tinted lips and the pretence of colour on the charming face. The close air of the room was drenched with the heavy atmosphere of perfumes, mingled with the pungent smell of cigarette smoke.

Miss Heredith took a seat by the bedside. The two women formed a striking contrast in types: the strong, rugged, practical country lady, and the fragile feminine devotee of beauty and personal adornment, who, in the course of time, was to succeed the other as the mistress of the moat-house. The difference went far beyond externals; there was a wide psychological gulf between them—the difference between a woman of healthy mind and calm, equable temperament, who had probably never bothered her head about the opposite sex, and a woman who was the neurotic product of a modern, nerve-ridden city; sexual in type, a prey to morbid introspection and restless desires.

The younger woman regarded Miss Heredith with a rather peevish glance of her large eyes. It was plain from the expression of her face that she disliked Miss Heredith and resented her intrusion, but it would have needed a shrewd observer to have deduced from Miss Heredith's face that her feeling towards her nephew's wife was one of dislike. There was nothing but constrained politeness in her voice as she spoke.

"How is your head now, Violet? Are you feeling any better?"

"No. My head is perfectly rotten." As she spoke, the girl pushed off her boudoir cap, and smoothed back the thick, fair hair from her forehead, with an impatient gesture, as though she found the weight intolerable.

"I am sorry you are still suffering. Will you be well enough to go to the Weynes' to-night?"

"I wouldn't dream of it. I wonder you can suggest it. It would only make me worse."

"Of course I shall explain to Mrs. Weyne. That is, unless you would like me to stay and sit with you. I do not like you to be left alone."

"There is not the slightest necessity for that," said Mrs. Heredith decisively. "Do go. I can ring for Lisette to sit with me if I feel lonely."

"Perhaps you would like Phil to remain with you?" suggested Miss Heredith.

"Oh, no! It would be foolish of him to stay away on my account. I want you all to go and enjoy yourselves, and not to fuss about me. At present I desire nothing so much as to be left alone."

"Very well, then." Miss Heredith rose at this hint. "Shall I send you up some dinner?"

"No, thank you. The housekeeper has just sent me some strong tea and dry toast. If I feel hungry later on I'll ring. But I shall try and sleep now."

"Then I will leave you. I have ordered dinner a little earlier than usual."

"What time is it now?" Violet listlessly looked at her jewelled wrist-watch as she spoke. "A quarter-past six—is that the right time?"

Miss Heredith consulted her own watch, suspended round her neck by a long thin chain.

"Yes, that is right."

"What time are you having dinner?"

"A quarter to seven."

"What's the idea of having it earlier?" asked the girl, propping herself up on her pillow with a bare white arm, and looking curiously at Miss Heredith.

"I have arranged for us to leave for the Weynes' at half-past seven. It is a long drive."

"I see." The girl nodded indifferently, as though her curiosity on the subject had subsided as quickly as it had arisen. "Well, I hope you will all have a good time." She yawned, and let her fair head fall back on the pillow. "Now I shall try and have a sleep. Please tell Phil not to disturb me. Tell him I've got one of my worst headaches. You are sure to be back late, and I don't want to be awakened."

She closed her eyes, and Miss Heredith turned to leave the room. As she passed the dressing-table her eyes fell upon a handsome jewel-case. As if struck by a sudden thought, she turned back to the bedside again.

"Violet," she said.

The girl half opened her eyes, and looked up at the elder woman from veiled lids. "Yes?" she murmured.

"Your necklace—I had almost forgotten. Mr. Musard goes back to town early in the morning, and he wishes to take it with him."

"Oh, it will have to wait until the morning. I don't know where the keys are, and I can't be bothered looking for them now." The girl turned her face determinedly away, and buried her head in the pillow, like a spoilt child.

Miss Heredith flushed slightly at the deliberate rudeness of the action, but did not press the request. She left the room, softly closing the door behind her. She walked slowly along the wide passage, hung with bugle tapestry, and paused for a while at a narrow window at the end of the gallery, looking out on the terrace gardens and soft green landscape beyond. The interview with her nephew's wife had tried her, and her reflections were rather bitter. For the twentieth time she asked herself why her nephew had fallen in love with this unknown girl from London, who loathed the country. From Miss Heredith's point of view, a girl who smoked and talked slang lacked all sense of the dignity of the high position to which she had been called, and was in every way unfitted to become the mother of the next male Heredith, if, indeed, she consented to bear an heir at all. It was Miss Heredith's constant regret that Phil had not married some nice girl of the county, in his own station of life, instead of a London girl.

Miss Heredith terminated her reflections with a sigh, and turned away from the window. She was above all things practical, and fully realized the folly of brooding over the inevitable, but the marriage of her nephew was a sore point with her. She proceeded in her stately way down the broad and shallow steps of the old staircase, hung with armour and trophies and family portraits. At the bottom of the stairs she encountered a manservant bearing a tray with sherry decanters and biscuits across the hall.

"Where is Mr. Philip?" she asked.

"I think he is in the billiard room, ma'am," the man replied.

Miss Heredith proceeded with rustling dignity to the billiard room. The click of billiard balls was audible before she reached it. The door was open, and inside the room several young men, mostly in khaki, were watching a game between a dark-haired man of middle age and a young officer. One or two of the men looked up as Miss Heredith entered, but the young officer went on stringing his break together with the mechanical skill of a billiard marker. Miss Heredith mentally characterized his action as another instance of the modern decay of manners. In her young days gentlemen always ceased playing when a lady entered the billiard room. The middle-aged player came forward, cue in hand, and asked her if she wanted anything.

"I am looking for Phil," she said. "I thought he was here."

"He was, but he has just gone to the library. He said he had some letters to write before dinner."

"Thank you." Miss Heredith turned away and walked to the library which, like the billiard room, was on the ground floor. She opened the door, and stepped into a large room with an interior which belonged to the middle ages. There was no intrusion of the twentieth-century in the great gloomy apartment with its faded arabesques and friezes, bronze candelabras, mediæval fittings, and heavy time-worn furniture.

The young man who sat writing at an ancient writing-table in the room was not out of harmony with the ancient setting. His face was of antique type—long, and narrow, and his long straight dark hair, brushed back from his brow, was in curious contrast to the close crop of a military generation of young men. His eyes were dark, and set rather deeply beneath a narrow high white forehead. He had the Heredith eyebrows and high-bridged nose; but, apart from those traditional features of his line, his rather intellectual face and slight frame had little in common with the portraits of the massive war-like Herediths which hung on the walls around him. He ceased writing and looked up as his aunt entered.

"I have just been to see Violet," Miss Heredith explained. "She says she is no better, and will not be able to accompany us to the Weynes' to-night. I suggested remaining with her, but she would not hear of it. She says she prefers to be alone. Do you think it is right to leave her? I should like to have your opinion. You understand her best, of course."

"I think if Violet desires to be alone we cannot do better than study her wishes," replied Phil. "I know she likes to be left quite to herself when she has a nervous headache."

"In that case we will go," responded Miss Heredith. "I have decided to have dinner a quarter of an hour earlier to enable us to leave here at half-past seven."

"I see," said the young man. "Is Violet having any dinner?"

"No. She has just had some tea and toast, and now she is trying to sleep. She does not wish to be disturbed—she asked me to tell you so." Miss Heredith glanced at her watch. "Dear me, it is nearly half-past six! I must go. Tufnell is so dilatory when quickness is requisite."

"Did you remind Violet about the necklace?" asked Phil, as his aunt turned to leave the library.

"Yes. She said she would send it down in the morning, before Vincent leaves."

Phil nodded, and returned to his letters. Miss Heredith left the room, and proceeded along the corridor to the big dining-room. An elderly man servant, grey and clean-shaven, permitted a faint deferential smile to appear on his features as she entered.

"Is everything quite right, Tufnell?" she asked.

Tufnell, the staid old butler, who had inherited his place from his father, bowed gravely, and answered decorously:

"Everything is quite right, ma'am."

Miss Heredith walked slowly round the spacious table, adjusting a knife here, a fork there, and giving an added touch to the table decorations. There was not the slightest necessity for her to do so, because the appointments were as perfect as they could be made by the hands of old servants who knew their mistress and her ways thoroughly. But it was Miss Heredith's nightly custom, and Tufnell, standing by the carved buffet, watched her with an indulgent smile, as he had done every evening during the last ten years.

While Miss Heredith was thus engaged, the door opened and Sir Philip Heredith entered the room in company with an old family friend, Vincent Musard.

CHAPTER III

Sir Philip Heredith was a dignified figure of an English country gentleman of the old type. He was tall and thin, aristocratic of mien, with white hair and faded blue eyes. His face was not impressive. At first sight it seemed merely that of a tired old man, weary of the paltry exactions of life, and longing for rest; but, at odd moments, one caught a passing resemblance to a caged eagle in a swift turn of the falcon profile, or in a sudden flash of the old eyes beneath the straight Heredith brows. At such times the Heredith face—the warrior face of a long line of fierce fighters and freebooting ancestors—leaped alive in the ageing features of the last but one of the race.

His companion was a man of about fifty-five. His face was brown, as though from hot suns, his close-cropped hair was silver-grey, and he had the bold, clear-cut features of a man quick to make up his mind and accustomed to command. His eyes were the strangest feature of his dominating personality. They were small and black, and appeared almost lidless, with something in their dark direct gaze like the unwinking glare of a snake. His apparel was unconventional, even for war-time, consisting of a worn brown suit with big pockets in the jacket, and a soft collar, with a carelessly arranged tie. On the little finger of his left hand he wore a ruby ring of noticeable size and lustre.

Vincent Musard was a remarkable personality. He came of a good county family, which had settled in Sussex about the same time that the first Philip Heredith had burnt down the moat-house, but his family tree extended considerably beyond that period. If the name of Here-Deith was inscribed in the various versions of the Roll of Battle Abbey to be seen in the British Museum, the name of Musard was to be found in the French roll of "Les Compagnons de Guillaume à la Conquête de l'Angleterre en 1066," the one genuine and authentic list, which has received the stamp of the French Archæological Society, and is carved in stone and erected in the Church of Dives on the coast of Normandy. Vincent Musard was the last survivor of an illustrious line, a bachelor, explorer, man of science, and connoisseur in jewels. He had been intended for the Church in his youth, but had quarrelled with it on a question of doctrine. Since then he had led a roving existence in the four corners of the earth, exploring, botanizing, shooting big game, and searching for big diamonds and rubies. He had written books on all sorts of out-of-the-way subjects, such as "The Flora of Chatham Islands," "Poisonous Spiders (genus Latrodectua) of Sardinia," "Fossil Reptilia and Moa Remains of New Zealand," and "Seals of the Antarctic." But his chief and greatest hobby was precious stones, of which he was a recognized expert.

His father had left him a comfortable fortune, but he had made another on his own account by his dealings in gems, which he collected in remote corners of the world and sold with great advantage to London dealers. He was intimately acquainted with all the known mines and pearl fisheries of the world, but his success as a dealer in jewels was largely due to the fact that he searched for them off the beaten track. He had explored Cooper's Creek for white sapphires, the Northern Territory for opals, and had once led an expedition into German New Guinea in search of diamonds, where he had narrowly escaped being eaten by cannibals.

The passage of time had not tamed the fierce restlessness of his disposition. Although he was not quite such a rover as of yore, the discovery of a new diamond field in Brazil, or the news of a new pearl bed in southern seas, was sufficient to set him packing for another jaunt half round the world. He was the oldest friend of the Herediths, and Miss Heredith, in particular, had a high opinion of his qualities. Musard, on his part, made no secret of the fact that he regarded Miss Heredith as the best of living women. It had, indeed, been rumoured in the county a quarter of a century before that Vincent Musard and Alethea Heredith were "going to make a match of it."

It was, perhaps, well for both that the match was never made. Musard had departed for one of his tours into the wilds of the world, not to return to England until five years had elapsed. Their mutual attraction was the attraction of opposites. There was nothing in common except mutual esteem between a wild, tempestuous being like Musard, who rushed through life like a whirlwind, for ever seeking new scenes in primitive parts of the earth, and the tranquil mistress of the moat-house, who had rarely been outside her native county, and revolved in the same little circle year after year, happy in her artless country pursuits and simple pleasures.

Of late years, Musard had spent most of his brief stays in England with the Herediths. He had his own home, which was not far from the moat-house, but he was a companionable man, and preferred the warm welcome and kindly society of his old friends to the solitary existence of a bachelor at Brandreth Hall, as his own place was named.

He had recently returned to England after a year's wanderings in the southern hemisphere, and had arrived at the moat-house on the previous day, bringing with him a dried alligator's head with gaping jaws, a collection of rare stuffed birds and snakeskins for Phil, who had a taste in that direction, and a carved tiki god for Miss Heredith. He had also brought with him his Chinese servant, two kea parrots, and a mat of white feathers from the Solomon Islands, which he used on his bed instead of an eiderdown quilt when the nights were cold. He had left in his London banker's strong room his latest collection of precious stones, after forwarding anonymously to Christie's a particularly fine pearl as a donation towards the British Red Cross necklace.

Musard's present stay at the moat-house was to be a brief one. The British Government, on learning of his return to his native land, had asked him to go over to the front to adjust some trouble which had arisen between the head-men of a Kaffir labour compound. As Musard's wide knowledge of African tribes rendered him peculiarly fitted for such a task, he had willingly complied with the request, and was to go to France on the following day.

Miss Heredith had taken advantage of his brief visit to consult him about the Heredith pearl necklace—a piece of jewellery which was perhaps more famous than valuable, as some of the pearls were nearly three hundred years old. Sir Philip had given it to Violet when she married Phil. But Violet had locked it away in her jewel-case and never worn it. She had said, only the night before, that the setting of the clasp was old-fashioned, and the pearls dull with age. Miss Heredith, although much hurt, had realized that there was some truth in the complaint, and she had asked Musard for his advice. Musard had expressed the opinion that perhaps the pearls were in need of the delicate operation known as "skinning," and had offered to take the necklace to London and obtain the opinion of a Hatton Garden expert of his acquaintance.

Vincent Musard smiled at Miss Heredith in friendly fashion as he entered the dining-room, and Sir Philip greeted his sister with polite, but somewhat vague courtesy. Sir Philip's manner to everybody was distinguished by perfect urbanity, which was so impersonal and unvarying as to suggest that it was not so much a compliment to those upon whom it was bestowed as a duty which he felt he owed to himself to perform with uniform exactitude.

Musard began to talk about the arrangements for his departure the following day, and asked Tufnell about the trains. On learning that the first train to London was at eight o'clock, he expressed his intention of catching it.

"Is it necessary for you to go so early, Vincent?" inquired Miss Heredith. "Could you not take a later train?"

"I daresay I could. Why do you ask?"

"I was thinking about the necklace. Violet was too unwell to give it to me to-night, and she may not be awake so early in the morning. I should like you to take it with you, if it could be managed."

"I can take a later train. It will suit me as well."

"Is Violet unable to go with us to the Weynes' to-night?" said Sir Philip, glancing at his sister.

"Yes; her head is too bad."

"It is a pity we have to go without her, as the party is given in her honour. Of course, we must go."

"Where is her necklace?" asked Musard. "Is it in the safe?"

"No," replied Miss Heredith. "It is in Violet's room, in her jewel-case."

"Well, as Mrs. Heredith will be alone in the house to-night, I think it would be wise if you locked it in the safe," said Musard. "There are many servants in the house."

"I think that is quite unnecessary, Vincent. Our servants are all trustworthy."

"Quite so, but several of your guests have brought their own servants—maids and valets."

"Very well. If you think so, Vincent, I will see to it after dinner."

The conversation was terminated by the sound of the dinner-gong. The guests came down to dinner in ones and twos, and assembled in the drawing-room before proceeding to the dining-room. The men who were not in khaki were dressed for dinner. The gathering formed a curious mixture of modern London and ancient England. The London guests, who were in the majority, consisted of young officers, some young men from the War Office and the Foreign Office, a journalist or two, and the ladies Miss Heredith had entertained at tea on the lawn. These people had been invited because they were friends of the young couple, and not because they were anybody particular in the London social or political world, though one or two of the young men had claims in that direction. Mingled with this very modern group were half a dozen representatives of old county families, who had been invited by Miss Heredith.

The party sat down to dinner. There were one or two murmurs of conventional regret when Miss Heredith explained the reason of Mrs. Heredith's vacant place, but the majority of the London guests—particularly the female portion—recognized the illness as a subterfuge and accepted it with indifference. If Mrs. Heredith was bored with her guests they, on their part, were tired of their visit. The house party had not been a success. The London visitors found the fixed routine of life in a country house monotonous and colourless, and were looking forward to the termination of their visit. The life they had led for the past fortnight was not their way of life. They met each morning for breakfast at nine o'clock—Miss Heredith was a stickler for the mid-Victorian etiquette of everybody sitting down together at the breakfast table. After breakfast the men wandered off to their own devices for killing time: some to play a round of golf, others to go shooting or fishing, generally not reappearing until dinner-time. After dinner they played billiards or auction bridge, and the ladies knitted war socks or sustained themselves till bedtime with copious draughts of the mild stimulant supplied by their favourite lady novelists. At half-past ten o'clock Tufnell entered with a tray of glasses, and the guests partook of a little refreshment. At eleven Miss Heredith bade her visitors a stately good-night, and they retired to their bedrooms. The great lady of the moat-house was a firm believer in the axiom that a woman should be mistress in her own household, and she saw no reason why her guests should not adopt her way of life while under her roof. She was a country woman born and bred, believing in the virtues of an early bed and early rising, and she was not to be put out of her decorous regular way of living by Londoners who turned night into day with theatres, late suppers, night clubs, and other pernicious forms of amusement which Miss Heredith had read about in the London papers.

Dinner at the moat-house was a solemn and ceremonious function. In accordance with the time-honoured tradition of the family, it was served at the early hour of seven o'clock in the big dining-room, an ancient chamber panelled with oak to the ceiling, with a carved buffet, an open fireplace, Jacobean mantelpiece, and old family portraits on the walls. There were sconces on the walls, and a crystal chandelier for wax candles was suspended from the centre of the ceiling above the table. The chandelier was never lit, as the moat-house was illuminated by electric light, but it looked very pretty, and was the apple of Miss Heredith's eye—as the maidservants were aware, to their cost.

The dinner that night was, as usual, very simple, as befitted a patriotic English household in war-time, but the wines made up for the lack of elaborate cooking. Sir Philip Heredith and his sister followed their King's example of abstaining from wine during the duration of war, but it was not in accordance with Sir Philip's idea of hospitality to enforce abstinence on their guests, and the men, at all events, sipped the rare old products of the Heredith cellars with unqualified approval, enhanced by painful recollections of the thin war claret and sugared ports of London clubs. Such wine, they felt, was not to be passed by. Of the young men, Phil Heredith alone drank water, not for the same reason as his father, but because he had always been a water drinker.

Under the influence of the good wine the guests brightened up considerably as the meal proceeded. Sir Philip, in his old-fashioned way, raised his glass of aerated water to one and another of the young men. He was an ideal host, and his unfailing polished courtesy hid the fact that he was looking forward to the break up of the party with a relief akin to that felt by the majority of his guests. Conversation had been confined to monosyllables at first, but became quite flourishing and animated as the dinner went on. Miss Heredith smiled and looked pleased. As a hostess, she liked to see her guests happy and comfortable, even if she did not like her guests.

The conversation was mainly about the war: the Allies' plans and hopes and fears. Several of the young men from London gave their views with great authority, criticising campaigns and condemning generals. Phil Heredith listened to this group without speaking. Two country gentlemen in the vicinity also listened in silence. They were amazed to hear such famous military names, whom they had been led by their favourite newspapers to regard as the hope of the country's salvation, criticised so unmercifully by youngsters.

"And do you think the war will soon be over, Mr. Brimley?" said a feminine voice, rather loudly, during a lull in the conversation. The speaker was a near neighbour and friend of Miss Heredith's, Mrs. Spicer, who was not a member of the house party, but had been invited to dinner that night and was going to the Weynes' afterwards. She was stout and fresh-faced, and looked thoroughly good-natured and kind-hearted.

She addressed her question to a tall young man with prematurely grey hair, prominent eyes, and a crooked nose. His name was Brimley, and he was well-known in London journalism. His portrait occasionally appeared in the picture papers as "one of the young lions of Fleet Street," but his enemies preferred to describe him as one of Lord Butterworth's jackals—Lord Butterworth being the millionaire proprietor of an influential group of newspapers which, during the war, had stood for "the last drop of blood and the last shilling" rallying cry. As one of the foremost of this group of patriots, Mr. Brimley had let his ink flow so freely in the Allies' cause that it was whispered amongst those "in the know" that he was certain for a knighthood, or at least an Empire Order, in the next list of honours.

Mr. Brimley looked at the speaker haughtily, and made an inaudible reply. Although he was a lion of Fleet Street, he did not relish being called upon to roar in the wilds of Sussex.

"Won't the poor German people be delighted when our troops march across the Rhine to deliver them from militarism," continued the old lady innocently.

There was a subdued titter from the younger girls at this, and a young officer sitting near the bottom of the table laughed aloud, then flushed suddenly at his breach of manners.

"Have I said something foolish?" asked the old lady placidly. "Please tell me if I have—I don't mind."

"Not at all," said another young officer, with a beardless sunburnt face. "Personally, I quite agree with you. The Germans ought to be jolly well pleased to be saved from their beastly selves."

"What a number of land girls you have in this part of the world, Miss Heredith," remarked the young officer who had laughed, as though anxious to turn the conversation. "I saw several while I was out shooting to-day, and very charming they looked. I had no idea that sunburn was so becoming to a girl's complexion. I saw one girl who had been riding a horse through the woods, and she looked like what's-her-name—Diana. She had bits of green stuff sticking all over her, and cobwebs in her hair."

"That reminds me of a good story," exclaimed a chubby-faced youth in the uniform of the Flying Corps. "You'll appreciate it, Denison. Old Graham, of the Commissariat, was out golfing the other day, and he turned up at the club all covered with cobwebs. Captain Harding, of our lot, who was just back in Blighty from eighteen months over there, said to him, 'Hullo, Graham, I see you've been down at the War Office.' Ha, ha!"

The other young men in khaki joined in the laugh, but a tall gaunt man with an authoritative glance, the Denison referred to, looked rather angry. Miss Heredith, with a hostess's watchful tact for the suspectibilities of her guests, started to talk about a show for allotment holders which had been held in the moat-house grounds a few weeks before. It seemed that most of the villagers were allotment holders, and the show had been held to stimulate their patriotic war efforts to increase the national food supply. The village had entered into it with great spirit, and some wonderful specimens of fruit, vegetables, poultry and rabbits had been exhibited.

"The best part of it was that Rusher, my own gardener, was beaten badly in every class," put in Sir Philip, with a smile.

"Not in every class," corrected Miss Heredith. "The peaches and nectarines from the walled garden were awarded first prize."

"Rusher was beaten in the vegetable classes—in giant vegetable marrows and cabbages," retorted Sir Philip, with a chuckle. "He hasn't got over it yet. He suspects the vicar of favouritism in awarding the prizes. The fact that his daughter won first prize for rabbits with a giant Belgian did little to console him."

"And we raised quite a respectable sum for the Red Cross by charging threepence admission to see a stuffed menagerie of Phil's," added Miss Heredith.

"A stuffed menagerie! What a curious thing," remarked a young lady.

"Not quite a menagerie," said Sir Philip. "Merely the stuffed remains of some animals Phil used to keep as a youngster. When they died—as they invariably did—he used to skin them and stuff them. He was quite an expert taxidermist."

"Tell them about your museum exhibit, Philip," said Miss Heredith, with quite an animated air.

"We also arranged a little exhibition of—er—old things," continued Sir Philip diffidently. "Armour, miniatures, some old jewels, and things like that. That also brought in quite a respectable sum for the Red Cross."

"From the Heredith collection, I presume?" said Mr. Brimley.

"What wonderful old treasures you must have in this wonderful old house of yours," gushed the young lady who had spoken before. "I am so disappointed in not seeing the Heredith pearl necklace. What a pity dear Mrs. Heredith is ill. She was going to wear the pearls to-night, and now I shall have to go away without seeing them."

Sir Philip bowed. He did not quite relish the trend of the conversation, but he was too well-bred to show it.

"You shall see the pearls in the morning," said Miss Heredith courteously.

"I adore pearls," sighed the guest.

"If you admire pearls, you should see the collection which is being made for the British Red Cross," remarked Vincent Musard. "I had a private view the other day. It is a truly magnificent collection."

All eyes were turned on the speaker. The topic interested every lady present, and they were aware that Musard was one of the foremost living authorities on jewels. The men had all heard of the famous traveller by repute, and they wanted to listen to what he had to say. Musard seemed rather embarrassed to find himself the object of general attention, and went on with his dinner in silence. But some of the ladies were determined not to lose the opportunity of learning something from such a well-known expert on a subject so dear to their hearts, and they plied him with eager questions.

"It must be a wonderful collection," said a slight and slender girl named Garton, with blue eyes and red hair. She was a lady journalist attached to Mr. Brimley's paper. Twenty years ago she would have been called an advanced woman. She believed in equality for the sexes in all things, and wrote articles on war immorality, the "social evil" and kindred topics in a frank unabashed way which caused elderly old-fashioned newspaper readers much embarrassment. Miss Garton was just as eager as the more frivolous members of her sex to hear about the Red Cross pearls, and begged Mr. Musard to give her some details. She would have to do a "write up" about the necklace when she returned to London, she said, and any information from Mr. Musard would be so helpful.

"It is not a single necklace," said Musard. "There are about thirty necklaces. The Red Cross committee have already received nearly 4,000 pearls, and more are coming in every day."

"Four thousand pearls!" "How perfectly lovely!" "How I should love to see them!" These feminine exclamations sounded from different parts of the table.

"I suppose the collection is a very fine and varied one?" observed Sir Philip.

"Undoubtedly. The committee have had the advice of the best experts in London, who have given much time to grading the pearls for the different necklaces. In an ordinary way it takes a long while—sometimes years—to match the pearls for a faultless necklace, but in this case the experts have had such a variety brought to their hands that their task has been comparatively easy. But in spite of the skilful manner in which the necklaces have been graded, it is even now a simple matter for the trained eye to identify a number of the individual pearls. The largest, a white pearl of pear shape, weighing 72 grains, would be recognized by any expert anywhere. There are several other pearls over thirty grains which the trained eye would recognize with equal ease in any setting. The few pink and black pearls are all known to collectors, and it is the same with the clasps. One diamond and ruby clasp is as well-known in jewel history as the State Crown. The diamonds are in the form of a Maltese Cross, set in a circle of rubies."

"That must have been the gift of the Duchess of Welburton," remarked Sir Philip. "She inherited it from her great aunt, Adelina, wife of the third duke. There was a famous pearl necklace attached to the clasp once, but it disappeared about ten years ago at a ball given by the German Ambassador, Prince Litzovny. I remember there was a lot of talk about it at the time, but the necklace was never recovered. The clasp, too, has a remarkable history."

"All great jewels have," said Musard. "In fact, all noteworthy stones have dual histories. Their career as cut and polished gems is only the second part. Infinitely more interesting is the hidden history of each great jewel, from the discovery of the rough stone to the period when it reaches the hands of the lapidary, to be polished and cut for a drawing-room existence. What a record of intrigue and knavery, stabbings and poisonings, connected with some of the greatest jewels in the British Crown—the Black Prince's ruby, for example!"

Musard gazed thoughtfully at the great ruby on his own finger as he ceased speaking. The guests had finished dinner, and Miss Heredith, with a watchful eye on the big carved clock which swung a sedate pendulum by the fireplace, beckoned Tufnell to her and directed him to serve coffee and liqueurs at table.

"What is your favourite stone, Mr. Musard?" said a bright-eyed girl sitting near him, after coffee had been served.

"Personally I have a weakness for the ruby," replied Musard. "Its intrinsic value has been greatly discounted in these days of synthetic stones, but it is still my favourite, largely, I suppose, because a perfect natural ruby is so difficult to find. I remember once journeying three thousand miles up the Amazon in search of a ruby reputed to be as large as a pigeon's egg. But it did not exist—it was a myth."

"What a life yours has been!" said the girl. "How different from the humdrum existence of us stay-at-homes! How I should like to hear some of your adventures. They must be thrilling."

"If you want to hear a real thrilling adventure, Miss Finch, you should get Mr. Musard to tell you how he came by that ruby he is wearing," said Phil Heredith, joining in the conversation.

The eyes of all the guests were directed to the ring which Musard was wearing on the little finger of his left hand. The stone in the plain gold setting was an unusually large one, nearly an inch in length. The stone had been polished, not cut, and glowed rather than sparkled with a deep rich red—the true "pigeon's-blood" tint so admired by connoisseurs.

"Nonsense, Phil"—Musard flushed under his brown skin—"your guests do not want to hear me talk any more about myself. I've monopolized the conversation too long already."

"Oh, please do tell us!" exclaimed several of the guests.

"Really, you know, I'd rather not," responded Musard, in some embarrassment. "It's a long story, for one thing, and it's not quite—how shall I express it—it's a bit on the horrible side to relate in the presence of ladies."

"I do not think that need deter you," remarked one of the young officers drily. "We are all pretty strong-minded nowadays—since the War."

"Oh, we should love to hear it," said the lady journalist, who scented good "copy." "Shouldn't we?" she added, turning to some of the ladies near her.

"Yes, indeed!" chorused the other ladies. "Do tell us."

"Go ahead, Musard—you see you can't get out of it," said Phil.

"Perhaps, Phil, as Mr. Musard does not think it a suitable story—" commenced Miss Heredith tentatively. Her eye was fixed anxiously on the clock, which was verging on twenty minutes past seven, and she feared the relation of her old friend's experience might make them late at the Weynes. But at that moment Tufnell approached his mistress and caught her eye. A slight shade of annoyance crossed her brow as she listened to something he communicated in a low voice, and she turned to her guests.

"I must ask you to excuse me for a few moments," she said.

She rose from her place and left the room. As the door closed behind her the ladies turned eagerly to Musard.

"Now, please, tell us about the ruby," said several in unison.

The explorer glanced at the eager faces looking towards him.

"Very well, I will tell you the story," he said quietly, but with visible reluctance.

CHAPTER IV

"It was before the war. Many strange things have happened in the world before the Boche broke loose with his dream of 'Deutschland über Alles.' I had been to Melville Island trying to match a pearl for the Devonshire necklace, and I went from the pearl fisheries to New Zealand, led there by rumours of the discovery of some wonderful black pearls. It was, however, a wild-goose chase. These rumours generally are. One of the experts of the New Zealand Fishery Department had been exploring the Haurakai Gulf, and returned to Auckland with a number of black pearls, which he had found in an oyster-bed on one of the Barrier Islands. He thought his fortune was made, though, being a fishery expert, he ought to have known better. They were black pearls right enough, but they came from edible oysters, and were valueless as jewels—not worth a shilling each.

"I put up at the Royal hotel, Auckland, waiting for a ship to take me back to England. I had arranged to return round the Cape, to look at a parcel of diamonds which were expected to arrive at Capetown from the fields in about six weeks' time. The day before I was due to sail, a rough-looking man named Moynglass, a miner, came to the hotel to see me. He had heard of me as a mining expert, and he had a business proposition which he wanted to place before me.

"He told me he and four others had just returned to Auckland after putting in six weeks among the volcanic beaches of the North Island, searching—'fossicking,' he called it—for fine gold. These black sand volcanic beaches are common in parts of New Zealand. The black sand is derived from the crystals of magnetic iron, and there is frequently a fair amount of fine gold mingled with them. By the continued action of the surf the heavier materials, gold, and ironstone sand, are mingled together between high and low water mark, and what appears as a stratum of black sand is found on the surface or buried under the ordinary sand. The gold is usually very fine, and the trouble of sifting and collecting it is great. A man works for wages, and hard-earned wages at that, who goes in for this kind of mining. But your true miner is ever an adventurer and a gambler, and gold thus won is dearer to his heart than gold which might be earned with less effort and more regularity in the form of sovereigns. You see, there is always the chance of a big find.

"Moynglass and his party had met with fair success along the beaches, but they wanted more than that. Moynglass was anxious to trace the fine gold to its source, and find a fortune. He believed, like most miners, that this fine gold is carried along the beds of the larger rivers and distributed by the action of the sea along the different beaches where it is found. His theory was that if the drift of the gold sands could be traced to their source, a great quartz reef would be found which would make the discoverers wealthy men. But he and his mates knew nothing about geology, and they wanted somebody to go with them who could chart the course, and lead them to the launching point of the gold.

"I had heard this theory before, and was not impressed by it. I should probably have turned down Moynglass's proposition if, in the course of his conversation, he had not produced a sample of ruby quartz from his pocket and showed it to me. He said he had found it while exploring one of the rivers of the Urewera country. I examined the quartz attentively. It was emery rock, and imbedded in the pale green mass were ruby crystals, and true Oriental rubies at that. I realized the valuable nature of the discovery, and questioned the man closely as to where he had obtained the ruby rock, but he became instantly suspicious, and guarded in his replies. If I joined his party—well and good: he would show me the spot, and we would share and share alike, but he would tell me nothing otherwise.

"I decided to go, and the terms were agreed upon. We set out from Auckland, the five of us, a week later. We went by coastal steamer to a little port in the Bay of Plenty, and there we plunged into the Urewera Mountains. My companions thought of nothing but the search for the source of the golden sands, but I was interested only in the ruby rock. There lay the fortune, if I could find it. I carried the specimen of corundum in my waistcoat pocket.

"The river we were ascending to its source was called the Araheoa. It was a rushing, noisy torrent, winding along a deep and narrow gorge, which in places almost met overhead. Some patches of olivine and serpentine encouraged me to think that we should find a heavy belt of the rock somewhere along the upper part of the valley, but my hopes were not realized. Day after day passed, and I found no more of it. When my companions washed the sands of likely stretches of river beach for fine gold, I examined the waste for corundum crystals, but I found no signs of them.

"We followed the river until we reached an inaccessible mountain gorge which seemed to bar our further progress. But, by diverting our course some miles to the northward, we were able to ascend to the upper reaches of the river, and, here, to my delight, I found the banks and rapids studded with great green masses of olivine rocks.

"I was anxious to examine these rocks, which extended up the mountain side, and my companions agreed with me that it was advisable to leave the bed of the river for the spur of the mountains where the river apparently took its rise. We crossed the stream, and commenced a gradual but oblique ascent of the spur. But after climbing for some hours we found our further progress stopped by a wide and deep gully, a sinister place, full of masses of dark green rocks. At the foot of one of the largest of these rocks we came across a large hole descending almost perpendicularly into the earth.

"We lit our lamps and descended. After some scrambling we found ourselves on a landing-place, from which another low passage of an easier gradient led into a large cave in the solid rock.

"The surface underneath our feet was covered with a dust so fine that it slipped from beneath us like sand, and rose in thick clouds about us. The cave was high enough to walk upright in, and seemed to run a great distance, with many lateral passages and smaller recesses off the principal chamber. Moynglass entered one of these passages and disappeared from view. A few moments afterwards we heard him, in a very excited voice, calling us to follow him.

"We proceeded stooping, in Indian file, down the passage, and found Moynglass in a smaller cave at the end of it, staring intently at something which was at first difficult to see in the gloom. Then, by the light of our lamps, we made out a sapling sticking up between two rocks, with a withered human hand impaled on it by a rusty sheath knife.

"As I was examining it, one of my companions, who had been exploring the cave, gave a cry of astonishment which caused me to look round. In a corner of the cave, revealed by his lamp, lay two skeletons side by side. The hand of one skeleton was missing, and in the eye of the other there gleamed a large uncut ruby. We examined the skeletons and searched the cave, but found nothing to throw any light on the mystery or reveal any clue of identity. There was not a vestige of food or clothing around the remains, and not a scrap of writing—only the two crumbling skeletons, the sapling, the sheath knife, and the ruby.

"What had brought about such a tragedy in the dim recesses of that prehistoric cave? Who could say? Perhaps the men had been prospecting together, and one had found the ruby and hidden in the cave, where his companion had found him and cut off his right hand with some primitive idea of making his vengeance fit the crime. Then, perhaps, they had been unable to escape from the cave, and had died together of thirst and hunger. But what is the use of speculating? The secret must ever remain hidden in the cave where the skeletons still lie."

Musard stopped abruptly, and sat staring straight in front of him. His strange eyes had a fixed look, as if gazing into the distance. His brown hand rested lightly on the white tablecloth, and the great ruby on his little finger gleamed fitfully in the light.

"You haven't told us all the story yet," said Phil Heredith quietly.

The other looked doubtfully at the ring of intent faces regarding him. "I left that part untold for a good reason," he admitted. "It is—well, I thought it a little bit too horrible to relate."

"Oh, do tell us," said the lady journalist enthusiastically. "We are all dying to hear it. It is such an unusual and exciting story that it would be cruel to leave us in suspense about the end."

"Very well, then," said Musard, as the other ladies chorused their approval. "We left the cave, and Moynglass, who considered himself the leader of the expedition, put the ruby in his pocket. That night we camped at a wild desolate spot, not far from the edge of a cliff about two hundred feet high, at the foot of which the bitter sulphurous waters of the river flowed into a chasm. In the morning we found Moynglass lying dead in his blanket, with the rusty sheath knife he had brought away from the cave sticking in his breast. The ruby was gone, and, so, also, was the eldest member of our party—an elderly dark-faced Irishman named Doyne, who, the previous day, had angrily disputed Moynglass's right to carry the ruby.

"We searched for Doyne all that day, but could find no trace of him. The next day we tracked across a glacier-like expanse littered with large blocks of sandstone. It was a grim spot. A horrible, stony, treeless waste which might have been the birthplace of the earth and the scene of Creation—a tableland between great mountains, full of masses of rhodonite contorted into grotesque shapes of stone images; a place where our lightest whispers came shouting back out of the profound stillness from the huge castellated black rocks bristling on the edge of a precipice which slit the valley from end to end.

"It was there we found Doyne, staggering along the lip of the gorge. He had gone mad in the solitude, and was wandering along bareheaded, tossing his arms in the air as he walked. When I saw him I thought of Cain trying to escape from the wrath of God after killing Abel. He saw us as soon as we saw him, and started to run. We set out in pursuit, but he fled with great speed, leaping from rock to rock like a mountain goat. He was getting away from us when he slipped and fell into the chasm with a loud cry. We found a path down the precipice and descended, and discovered him at the foot, battered to death, with the ruby clutched in his hand. That ended the expedition. The others insisted on returning to the coast without delay, and when we arrived there they gladly sold their shares in the ruby to me."

There was rather a long silence when the explorer had finished his narration. The long hand of the clock on the mantelpiece was creeping past the half-hour, but the circle round the dining-room table had been so enthralled by the story that nobody had noted the passage of time.

"What a ghastly adventure, Mr. Musard!" began one of the ladies, with a mirthless little laugh. "Did you never discover anything more about the two dead men in the cave?"

"No," replied Musard. "As I said, there were no papers or any clue to throw light on their identity. The skeletons must have lain there for many years, for the bones were crumbling into decay."

"You have never revisited the spot?" asked Sir Philip.

"I was in the Ureweras two years later with a Maori guide, investigating copper deposits for the New Zealand Government, but I did not go back to the valley."

"Would it not have been possible to give the poor things—the skeletons, I mean—Christian burial?" Mrs. Spicer asked timidly.

"It was impossible to dig a grave in the solid rock. Besides, they have a sepulchre of Nature's which will outlast any human grave," replied Musard.

"The thing that puzzles me is how the ruby got into the skeleton's eye," remarked the lady journalist musingly. "If that was the skeleton of the man who killed the other for stealing the ruby, who placed the ruby where you found it? Obviously, he could not have done it himself, for it must have been put there after death. Who, then, could it have been?"

"I have no idea," said Musard, in a tone which suggested that he did not care to discuss the subject further.

"May I look at the ring?" Miss Garton asked.

Musard drew it off his finger and handed it to her in silence. The others wanted to see it, so it was passed from hand to hand round the table, to the accompaniment of many admiring comments on the size and beauty of the stone. One of the young officers, with an air of much interest, asked Musard whether he thought there were other rubies like it to be found near the spot.

"Hardly in that form," replied Musard. "It is a puzzle to me how the men who found the ruby managed to get it out of the ruby rock and partially polish it. They had no tools or instruments of any kind—at least, we found none in the cave. Undoubtedly there are rubies in that part of the world. It was near the valley that Moynglass found his sample of corundum, with a ruby crystal in it. On our way back, at the head of the valley, I came across a belt of magnesian rocks charged with ores of copper and iron, and probably containing the matrix of ruby crystals."

"I wonder you wear the thing," said the chubby-faced youth of the Flying Corps, handing the ring across the table to the explorer.

"Why not?" asked Musard.

"Well, I wouldn't care to wear a ring found in a skeleton's head. I should expect the old bus to flop to the ground while I was doing a stunt, if I had a thing like that on my finger. Aren't you frightened of being haunted by the original owner?"

"Oh, I don't know," replied Musard indifferently. "There's a horrible history attached to most jewels, if it comes to that. I am not superstitious." He replaced the ring on his finger, and added thoughtfully: "I suppose many people would regard it in that light—as a grim sort of relic. Certainly, I shall never forget the valley of rocks where we found it. It was the strangest place I have ever seen—a 'waste howling wilderness.' And sometimes I fancy I can still hear the cry Doyne gave as he slipped or jumped from one of the black rocks into space. I remember how it came ringing back from the cliffs a hundred times repeated. It was—"

He broke off suddenly, as a scream pealed through the moat-house—a wild shrill cry, which, coming from somewhere overhead, seemed to fill the dining-room with the shuddering, despairing intensity of its appeal. It was the shriek of a woman in terror.

The ladies at the dinner table regarded one another with frightened eyes and blanched faces.

"What was that?" several of them whispered together.

"It came from Violet's room! My God, what has happened?" exclaimed Phil. He sprang to his feet in agitation and pushed back his chair. His face was white, his mouth drawn, and he fumbled at his throat with a shaking hand, as though the pressure of his collar impeded his breathing. Musard rose from the table and walked to where the young man was standing.

"Don't get upset needlessly, Phil," he said soothingly, placing a hand on his shoulder.

Sir Philip had also risen from his seat, and for the briefest possible space the three men stood thus, facing each other, as if uncertain how to act. Then the tense silence of the dining-room was broken by the loud report of a fire-arm.

"Let me go!" cried Phil shrilly, shaking off Musard's arm. He turned and limped rapidly towards the door, and as he did so his infirmity of body was apparent. One of his legs was several inches shorter than the other, and he wore a high boot.

Musard reached the door before him in a few rapid strides, and Sir Philip came hurrying after his son. The rest of the male guests followed, flocking towards the door in a body.

The first sight that Musard's eye fell upon as he passed through the doorway was the figure of Miss Heredith, rapidly descending the staircase. By the hall light he could see that her face was pale and agitated. She walked swiftly up to her old friend, and laid a trembling hand on his arm.

"Oh, Vincent, I was just coming for you—something terrible must have happened!" she began, in a broken, sobbing voice. "I was going upstairs to my room, when I heard the scream, and then the shot. They must have come from Violet's room. Will you go up and see, Vincent?"

Musard did not wait for her concluding words. He was already mounting the staircase, taking two or three of the broad shallow stairs in his stride. Phil hobbled after him, and Sir Philip and some of the guests straggled up in their wake.

CHAPTER V

A shaded light in an alcove at the head of the stairs threw a dim light down the passage which led off the first-floor landing, but Musard felt for the electric switch and pressed it. The light flooded an empty corridor, with the door of the room nearest to him gaping into a dark interior.

Musard stepped inside the open door, struck a match to find the switch, and walked over and turned on the light. As he did so, Phil and his father reached the door and followed him into the room, where, less than two hours before, Miss Heredith had been with Phil's young wife, and left her to sleep. The room seemed as it had been then; there was no sign of any intruder. The cut-glass and silver bottles stood on the small table by the head of the bed; the gold cigarette case was open alongside them; a novel, flung face downward on the pillows, revealed a garish cover and the bold lettering of the title—"What Shall it Profit?"—as though the book had dropped from the hand of some one overcome by sleep. But the white rays of the electric globe, hanging in a shade of rose colour directly overhead, fell with sinister distinctness on the slender figure of the young wife, lying in a huddled heap on the bed, her fashionable rest gown stained with blood, which oozed from her breast in a sluggish stream on the satin quilt. A sharp, pungent odour was mingled with the heavy atmosphere of the room—the smell of a burning fabric. There was no disorder, no weapon, no indication of a struggle. Only the motionless, bleeding figure on the bed revealed to the guests clustering outside the room that somebody had entered and departed as silently as a tiger.

Musard went swiftly to the bedside and bent over the girl.

"She has been shot," he said, in a tone which was little more than a whisper.

"She has been murdered!" It was Phil, pressing close behind Musard, who uttered these words. "Murdered!" he cried, in an unnatural voice, which was dreadful to hear. He made a few steps in the direction of the bed with his arms outstretched, then stopped, and, swinging round, faced the guests who were thronging the corridor outside. "Murdered, I say!" he repeated. "Where is the murderer?"

He stood for a moment, fixing a wild eye on the group of frightened faces in the doorway, as though seeking the murderer among them. Then his face became distorted, and he fell to the ground. His limbs seemed to grow rigid as he lay; his legs were extended stiffly, the upper part of his arms were pressed against his breast, but the forearms inclined forward, with the palms of the hand thrown back, and the fingers wide apart. Even in his unconsciousness he looked as though he were warding off the horror of the sight which had stricken him to the ground.

In the presence of domestic calamity human nature betrays its inherent weakness. At such times the artificial outer covering of civilization falls away, and the soul stands forth, stark, primitive, forlorn, and cries aloud. The strain of the tremendous tragedy which had entered his house, swift-footed and silent, was too much for Sir Philip. He sank on his knees by the side of his unconscious son, whimpering like a child—a weak and helpless old man. There was no trace of the dignity of the Herediths or pride of race in the wrinkled face, now distorted with the pitiful grin of senility, as Sir Philip crouched over his son, stroking his face with feeble fingers.

One or two of the women in the passage became hysterical. The young men looked on awkwardly, with grave faces, not knowing what to do. There was something very English in their shy aloofness; in their dislike of intruding in the room unasked.

Musard, looking round from the bedside, glanced briefly at the prostrate figure of Phil, and then his gleaming eyes travelled to the group at the doorway. He, at all events, was calm, and master of himself.

"The ladies had better go downstairs," he said, speaking in a subdued voice, but with decision. "They can do no good here. And will you two"—he singled out two of the young men with his eye—"carry Phil downstairs? He has only fainted. Please take Sir Philip away also. Telephone for Dr. Holmes immediately, and send for Sergeant Lumbe. And some of you young men search the house thoroughly—at once. No, not this room. Search the house from top to bottom, and the grounds outside. Be quick! There is no time to be lost."

The group in the doorway melted away. The ladies, pale-faced and weeping, went downstairs together like a flock of frightened birds, and the young men, only too glad to obey somebody who showed nerve and resolution at such a moment, dispersed at once to search the house.

Musard was left in the room alone, but not for long. Miss Heredith entered from the corridor almost immediately. Tufnell accompanied her to the door, but stopped there, with staring eyes directed towards the bed. Miss Heredith's face was drawn, but she had recovered her self-control. She walked quickly towards Musard, who was still bending over the bed.

"Vincent!" she cried. "In pity's name tell me what dreadful thing has happened? They have carried Phil downstairs, and they tried to detain me, but I broke away from them and came straight to you. Is Violet——"

Musard sprang to his feet at the first sound of her voice, and wheeled round swiftly, as if trying to impose his body between her and the figure on the bed.

"Go back, Alethea!" he sternly commanded. "Go back, I say! This is no sight for you, and you can do no good."

He still sought to intercept her as she approached, but she gently put aside his detaining hand, and, walking to the bedside, looked down. Then, at that sight, her fingers sought for his with an impulsive feminine movement, and held them tight.

"Do not be afraid for me," she whispered. "See! I am calm—I may be able to help. Is she—dead?"

"Dying," said Musard sadly.

"Is it...?" her voice dropped to nothingness, but her frightened eyes, travelling fearfully into the shadowy corners of the big bedroom, completed the unspoken sentence.

Musard understood her, and bowed his head silently. Then, turning his face to the door, he beckoned Tufnell to approach. The old servant advanced tremblingly into the room, vainly endeavouring to compose his horror-stricken face into a semblance of the impassive mask of the well-trained English servant.

"Go downstairs and get me some hot water," said Musard quietly. "Look sharp—and bring it yourself. I do not want any maidservants here to go into hysterics."

Tufnell hastened away. Musard resumed his place at the bedside, silently watching the figure on the bed. There was blood on his hands and clothes.

"Is there no hope? Can nothing be done to save her?" whispered Miss Heredith.

"Nothing. The lung is penetrated. She is bleeding to death."

His quick eye noticed a change in the figure on the bed. The face quivered ever so slightly, and the blue eyes half opened. Then the stricken girl made an effort as though she wanted to sit up, but a sudden convulsion seized her, and she fell back on her pillow, with one little white hand, glittering with rings, flung above her head, as if she died in the act of invoking the retribution of a God of justice on the assassin who had blotted out her young life in agony and horror.

"She is dead," said Musard gently. "This is a terrible business, and our first duty is to try and capture the monster who committed this foul crime."

They stood there in silence for a moment, looking earnestly at one another. Outside, somewhere in the woodland, there sounded the haunting gush of a night-bird's song, shivering through the quietness like a silver bell. The sweet note finished in a frightened squawk, and was followed by the cry of an owl. The song had betrayed the singer.

Musard turned away from Miss Heredith, and walked restlessly around the bedroom, scanning the heavy pieces of furniture and the faded hangings, and peering into every nook and corner, as if seeking for the murderer's place of concealment. A roomy old wardrobe near the window attracted his eye, and he stopped in front of it and flung its doors open. It contained some articles of the dead girl's apparel—costumes and frocks—hanging on hooks.

His eye wandered to the window, shrouded in the heavy folds of the damask curtains. He walked over to it, and drew the curtains aside. The bottom half of the window was wide open.

Miss Heredith, who was following his movements closely, gave vent to a faint cry of surprise.

"The window!" she exclaimed.

Musard looked round inquiringly.

"The window—what of it?" he asked.

"It was closed when I came in here before dinner to see Violet."

"You are quite sure of that?"

"Oh, yes! At least, I think so."

"I do not understand you."

"I mean that the atmosphere of the room was heavy and thick, as if the window had not been opened all day."

"It has been a still, close day."

"But Violet never had a window open if she could help it. She disliked fresh air. She was always afraid of catching cold."

Musard looked out of the window into the velvet darkness of the night.

"If the window was closed before, the murderer has opened it and escaped through it," he said.

"It is hardly possible."

"Why not?" He turned round and faced her.

"The ground falls on that side. The window is nearly twenty feet from the ground. And—there is the moat to be crossed. There is no bridge on that side of the house, and this window opens on the garden. Don't you remember?"

"I remember now."

"I thought you would."

"Still——" Musard broke off abruptly, and walked away from the window.

Near the window stood the dressing-table. The swing oval mirror reflected its contents—ivory brushes, silver hand mirrors, all the costly bijoutry of a refined woman's toilet. Among them stood Violet's silver jewel-case. Musard strode over and examined the case. It was locked.

"This ought to be put away," he said.

"I was coming up to get it when I heard the scream," whispered his companion.

"Perhaps you will take charge of it now," he said, placing it in her hands. As he did so there flashed across his mind the cynical appropriateness of the old proverb about locking doors after stolen steeds.

There was a restraint and lack of spontaneity about their conversation of which both were acutely conscious. The note was forced, as though from too great an effort to strike the right key. A curious psychological change had swept over both since they stood together by the bedside of the dying woman. It had come with the entry of death. They conversed hurriedly and guardedly, as if they mistrusted each other. In each of them two entities were now apparent—a surface consciousness, which talked and acted mechanically, and a secondary inner consciousness, watchful, and fearful of misinterpretation of the spoken word. The faculties which make up the human mind are different and complex, and mysteriously blended. It may be that when tragedy upsets the frail structure of human life the brute instincts of watchfulness and self-preservation come uppermost, guarding against chance suspicion, or the loud word of accusation. Perhaps through Musard's mind was passing the thought of the strange manner in which the murder had been committed, and how he, by detaining everybody downstairs at the dinner table while he told his story had been an instrument in its accomplishment.

The situation was terminated by the arrival of Tufnell with some hot water. Almost on his heels came the young men who had been searching the house. Musard was relieved by their return, though his impassive face did not reveal his feelings. Miss Heredith left the room with Tufnell, taking the jewel-case with her. Musard met the young men at the threshold.

The tall young officer with the sunburnt face, Major Gardner, informed Musard that they had completed a search of the house from top to bottom, but had found nothing. They had also searched the grounds, without result.

"Mrs. Heredith is dead," Musard gravely informed them. "She died while you have been searching for the miscreant who fired the shot we heard at the dinner table. Gentlemen, he must be found. It seems hardly possible that he has succeeded in getting clear away in so short a time."

"We have searched the place from top to bottom," remarked one of the young men.

"It is a strange, rambling old place, and difficult to explore unless you know it thoroughly," said Musard.

"We have done the best we could."

"I do not doubt it, but there are many old nooks and corners in which a man might hide."

"His first thought, after such a dreadful crime, would be to get away as quickly as possible," said Major Gardner.

"But how did he escape? Certainly not by the staircase, because we rushed out from the dining-room directly we heard the shot, and we should have caught him on his way down."

"Is there not a window in the bedroom? Could he not have escaped that way?"

"The window is nearly twenty feet from the ground."

"An athletic man might jump that distance," remarked Major Gardner thoughtfully.

"I still think it possible he may be concealed about the premises," replied Musard. "There is an old unused staircase at the end of this passage, which opens on the south side of the moat-house. Did you find it? It shuts with a door at the top, and might easily have escaped your notice."

"I opened the door and went down the staircase," said the young flying officer. "Nobody could have escaped that way. The door at the bottom is locked, and there is no key."

The scared face of a maidservant at that moment appeared at the head of the stairs.

"If you please, sir," she said, addressing Musard, "one of the gentlemen downstairs sent me up to tell you that he has been trying for the last ten minutes to ring up the police, but he can't get an answer."

"Send the butler to me at once."

The maid disappeared, and in another moment the butler came hurriedly up the stairs.

"Tufnell," said Musard quickly, "you must go at once to the village and get Sergeant Lumbe and Dr. Holmes. Hurry off, and be as quick as you can. And now, gentlemen," he added, turning to the others, "let us go downstairs. While we are waiting for the police I will help you make another search of the house and grounds. The murderer may escape while we stand here talking. We have wasted too much valuable time already."

CHAPTER VI

The butler left the moat-house at a brisk pace which became almost a run after he crossed the moat bridge. His way across the park lay along the carriage drive, bordered by an avenue of tall trees, between an ornamental lake and some thick game covers, and then through the outer fields to the village.

It was a soft and mellow September night, with a violet sky overhead sprinkled with silver. But a touch of autumn decay was in the air, which was heavy and still, and a white mist was rising in thick, sluggish clouds from the green, stagnant surface of the lake. The wood was veiled in blackness, in which the trunks of the trees were just visible, standing in straight, regular rows, like soldiers at attention.

Tufnell hurried along this lonely spot, casting timid glances around him. He was not a nervous man at ordinary times, but like many country people, he had a vein of superstition running through his phlegmatic temperament, and the events of the night had swept away his calmness. The croaking of the frogs and the whispering of the trees filled him with uneasiness, and he kept glancing backwards and forwards from the lake to the wood, as though he feared the murderer might suddenly appear from the misty surface of the one or the dim recesses of the other.

He had almost reached the confines of the wood when he was startled by a loud whirr, which he recognized as the flight of a covey of partridges from a cover close at hand. What had startled them? Glancing fearfully around him he saw, or thought he saw, the crouching figure of a man in one of the bypaths of the wood, partly hidden by the thick branches which stretched across the path a short distance from the drive.

Tufnell's first impulse was to take to his heels, but he was saved from this ignominious act by the timely recollection that he was an Englishman, whose glorious privilege it is to be born without fear. So he stood still, and in a voice which had something of a quaver in it, called out:

"Who is there?"

In the wood a bird gave a single call like the note of a flute, the wind murmured in the tall avenue of trees, a frog splashed in the still waters of the lake, but there was no sound of human life. Glancing cautiously into the wood, the butler could no longer see anything crouching in the path. The man—if it had been a man—had vanished.

"It may have been my fancy," muttered the butler, speaking aloud as though to reassure himself by hearing his own voice.

He walked quickly onward, and was relieved when he had left the wood behind him, and could see the faint lights of the village twinkling beyond the fields. Crossing a footbridge which spanned a narrow stream at the bottom of the meadows, Tufnell climbed over a stile, and walked along the road on the other side until he reached a cottage standing some distance back from the road at the summit of a gentle slope. Tufnell ascended the slope and knocked loudly at the cottage door.

After the lapse of a few moments the door was opened by a woman with a candle in her hand—a stout countrywoman of forty, with a curved nose, prominent teeth, and hair screwed up in a tight knob at the back of her head. Her small grey eyes, scanning the visitor at the door, showed both surprise and deference. The butler of the moat-house was not in the habit of mixing with the villagers, and by them he was accounted something of a personage. He not only shone with the reflected glory of the big house, but was respected on his own merit as a "snug" man, who had saved money, and had a little property of his own.

"Is your husband at home, Mrs. Lumbe?" he asked, in response to her mute glance of inquiry. He spoke condescendingly, like a man who recognized the social gulf between them, but believed in being polite to the lower orders.

"Yes, he is in, Mr. Tufnell. Will you come inside?"

The butler rubbed his boots carefully on the doormat, and followed the woman down a narrow passage to a small sitting-room at the end of it, where a man was sitting, reading a newspaper and smoking a pipe.

"Robert," said the woman, "here is Mr. Tufnell to see you."

The man looked up from his newspaper in some surprise, and got up to greet his visitor. He was not in uniform, and his rough, ungainly figure and round red face revealed the countryman, but from the crown of his close-cropped bullet head to his thick-soled boots he looked like a rural policeman. There was an awkward pose about him as he stood up—a clumsy effort to maintain the semblance of an official dignity. The questioning look his ferret eyes cast at the butler through the haze of tobacco smoke which filled the room indicated his impression that the visit was not merely a neighbourly call. Tufnell did not leave him in doubt on the point.

"You are wanted at the moat-house at once, Sergeant Lumbe," he said gravely. "A terrible crime has been committed. Mrs. Heredith has been murdered."

"Murdered!" ejaculated the sergeant, looking vacantly across the table at his wife, who had given vent to a cry of horror. "Murdered!" he repeated, as though seeking to assure himself of the truth of the butler's statement by a repetition of the word.

"Yes. She was shot in her bedroom a little while ago while the other guests were at dinner. You must come at once."

Sergeant Lumbe laid his pipe on the table with a trembling hand. He was overwhelmed by the magnitude of the catastrophe, and hardly knew what to do. His previous experience of crime was confined to an occasional arrest of the village drunkard, who invariably went with him confidingly. His eye wandered to a bookcase in the corner of the room, as if he would have liked to consult a "Police Code" which was prominently displayed on one of the shelves. Apparently he realized the indignity of such a course in the presence of a member of the public, so he turned to Tufnell and said:

"I'll go with you, but I must first put on my tunic."

"Be as quick as you can," said the butler, taking a chair.

Sergeant Lumbe went into an inner room, where his wife followed him. Tufnell heard them whispering as they moved about. Then Sergeant Lumbe hastily emerged buttoning his tunic. There was an eager look on his face.

"The wife has been saying that we ought to take her brother along," he said. "He belongs to Scotland Yard. He's spending his holidays with us."

"Where is he?" asked Tufnell, impressed by the magic of the name of Scotland Yard.

"He's just stepped over to the Fox and Knot to have a game of billiards, finding it a bit lonesome here, after London. Do you think we might send for him and take him with us?"

"I think it would be a very good idea," said Tufnell. "But can he be got at once?" he added, with a glance at the little clock on the mantelpiece. "The sooner we return the better."

"The wife can bring him while I am changing my boots. Hurry down to the Fox, Maggie, and tell Tom he's wanted at once."

"Don't tell him what it's for until you get him outside," hastily counselled the butler as the policeman's wife was departing on her errand. "Sir Philip won't like it if he hears that what happened to-night was discussed in the Fox tap-room."

The little clock on the mantelpiece had barely ticked off five additional minutes when Mrs. Lumbe returned in a breathless state, accompanied by a young man with billiard chalk on his coat and hands.

"This is my brother, Detective Caldew," said Mrs. Lumbe, between pants, to the butler. "I told him about the murder, and we hurried back as fast as we could."

"It's a horrible crime, and we must lose no time while there is still a chance of catching the murderer," said the young man, regaining his breath more easily than his stout sister. He brushed the billiard chalk off his clothes as he spoke. "Let us go at once."

Tufnell cast a curious glance at the new-comer. He saw a man of about thirty-five, tall, well-built and dark, with a clean-shaven face and rather intelligent eyes under thick dark brows. He had some difficulty in recognizing Detective Caldew as the village urchin of a score of years before who had touched his cap to the moat-house butler as a great personage, second only in importance to Sir Philip Heredith himself.

Tufnell was not aware that in the former village boy who had become a London detective he was in the presence of a young man of soaring ambition. Caldew had gone to London fifteen years before with the idea of bettering himself. After tramping the streets of the metropolis for some months in a vain quest for work, he had enlisted in the metropolitan police force rather than return to his native village and report himself a failure. At the end of two years' service as a policeman he had been given the choice of transfer to the Criminal Investigation Department of Scotland Yard. He had gladly accepted the opportunity, and had shown so much aptitude for plain-clothes work that by the end of another two years he had risen to the rank of detective. Caldew thought he was on the rapid road to further promotion, and had married on the strength of that belief. But another ten years had passed since then, and he still occupied a subordinate position, with not much hope of promotion unless luck came his way. And there seemed very little chance of that. Caldew's professional experience had imbued him with the belief that the junior officers of Scotland Yard existed for no other purpose than to shoulder the blame for the mistakes of their official superiors, who divided amongst themselves the plums of promotion, rewards, and newspaper publicity. That, of course, was the recognized thing in all public departments. Caldew found no fault with the system. His great ambition was to obtain some opening which would bring him advancement and his share of the plums.

He believed his opportunity had arrived that night. It had always been his dream to have the chance to unravel single-handed some great crime—a murder for choice—in which he alone should have all the glory and praise and newspaper paragraphs. He determined to make the most of the lucky chance which had fallen into his hands, before anybody else could arrive on the scene. He had confidence in his own abilities, and thought he had all the qualifications necessary to make a great detective. He was, at all events, sufficiently acute to realize that opportunity seldom knocks twice at any man's door.

The three men set out for the moat-house. At the butler's request Sergeant Lumbe went ahead to summon the doctor, who lived on the other side of the village green, and while he was gone Caldew drew the details of the crime from his companion. Lumbe rejoined them at the footbridge which led across the meadows into the Heredith estate, and they proceeded on their way in silence. Sergeant Lumbe's brain—such as it was—was in too much of a whirl to permit him to talk coherently; Tufnell, habitually a taciturn individual, had been rendered more so than usual by the events of the night; and Caldew was plunged into such a reverie of pleasurable expectation, regarding the outcome of his investigations of the moat-house murder, that the stages of his promotion through the grades of detective, sub-superintendent, and superintendent, flashed through his mind as rapidly as telegraph poles flit past a traveller in a railway carriage. The crime which had struck down one human being in the dawn of youth and beauty, turned another into a murderer, and plunged an old English family into horror and misery, afforded Detective Caldew's optimistic temperament such extreme gratification that he could scarcely forbear from whistling aloud. But that is human nature.

They passed through the wood, and crossed the moat bridge. The mist was creeping out of the darkness on both sides of the moat-house, casting a film across the faint light which gleamed from one or two of the heavily shuttered windows. Caldew, pausing midway on the bridge to glance at the mist-spirals stealing up like a troop of ghosts, asked his brother-in-law if the moat was still kept full of water. He received an affirmative reply, and walked on again.

A maidservant answered Tufnell's ring at the front door, and informed him in a whisper that Sir Philip and Miss Heredith were in the drawing-room. Thither they bent their steps, and found Musard awaiting them near the door. He nodded to Sergeant Lumbe, whom he knew, and glanced interrogatively at Caldew. Lumbe announced the latter's identity.

"You had better come in here first," said Musard, opening the door of the drawing-room and revealing the baronet and Miss Heredith sitting within. Brother and sister glanced at the group entering the room.

"This is Detective Caldew, of Scotland Yard," Musard explained to them, indicating the young man. "He is staying with Lumbe, who thought it advisable to bring him."

"Have you told them everything?" Miss Heredith spoke to Tufnell. Her dry lips formed the words rather than uttered them, but the old retainer understood her, and bowed without speaking. "What do you wish to do first, Detective Caldew?" she added, turning to him, and speaking with more composure. She was quick to realize that he would take the lead in the police investigations. A glance at Sergeant Lumbe's flustered face revealed only too clearly that the position in which he found himself was beyond his official capabilities.

Caldew stepped briskly forward. He was in no way embarrassed by his unaccustomed surroundings or by the commanding appearance of the great lady who was addressing him. He was a man who believed in himself, and such men are too much in earnest to be diffident.

"I should like to ask a few questions first, madam," he said. "So far, I have heard only your butler's version of what happened." Without waiting for a reply he launched a number of questions, and made a note of the replies in a pocket-book.

Musard, who assisted Miss Heredith to answer the questions, was rather impressed by the quick intelligence the detective displayed in eliciting all the known facts of the murder, but Sergeant Lumbe, who remained standing near the door, was shocked to hear Caldew cross-questioning the great folk of the moat-house with such little ceremony. He thought his brother-in-law a very forward young fellow, and hoped that Miss Heredith would not hold him responsible for his free-and-easy manner.

"Now I should like to commence my investigations," said Caldew, replacing his pocket-book. "There has been too much time lost already. I will start with examining the room where the body is, if you please."

"Certainly." Miss Heredith rose from her seat as she uttered the word.

"My dear Alethea!"—Musard's tone was expostulatory—"I will take the detective upstairs. There is no need for you to come."

"I prefer to do so." Miss Heredith's tone admitted of no further argument. She was about to lead the way from the room when she paused and glanced at Tufnell. "When will Dr. Holmes be here?" she asked.

"Almost immediately, ma'am."

"You had better stay here and receive him, Philip." Miss Heredith placed her hand affectionately on her brother's shoulder. He had not spoken during the time the police were in the room, but had sat quietly on his chair, with bent head and clasped hands, looking very old and frail. "It will be as well for him to see Phil before going upstairs," she added.

Sir Philip looked up at the mention of his son's name. "Poor Phil," he muttered dully.

"I think the doctor should examine Phil the moment he comes," continued Miss Heredith, aside, to Musard. "His look alarms me. I fear the shock has affected his brain. Tufnell, be sure and show Dr. Holmes to Mr. Philip's room directly Sir Philip has received him."

"You can rely upon me to do so, ma'am," said Tufnell earnestly.

"Very well. We will now go upstairs."

She left the drawing-room and proceeded towards the broad oak staircase, with Musard close behind her. Detective Caldew followed more slowly, noting his surroundings. When they reached the head of the staircase Miss Heredith switched on the electric current, and the bedroom corridor sprang into light. Detective Caldew was surprised at its length.

"Where does this passage lead to?" he asked abruptly.

"To the south side of the moat-house," replied Musard.

"Has it any outlet?"

"Yes; a door at the end communicates with a narrow staircase, leading to another door at the bottom. The second door was a former back entrance—it opens somewhere near the servants' quarters, I think?" He glanced inquiringly at Miss Heredith.

"Those stairs are never used now," she replied. "The entrance door at the bottom of the staircase is kept locked."

"There are such things as skeleton keys," commented the detective.

Musard opened the door of the death-chamber and switched on the light. Caldew walked at once to the bedside. He drew away the covering which had been placed over the face of the young wife, and stood looking at her.

Death had invested her with pathos, but not with dignity. On the pallor of the death mask the tinted lips, the spots of rouge, the pencilled eyebrows of the dead face, were as clearly revealed as print on a white page. The lips were parted; the small white teeth were showing beneath the upper lip. The little nose rose in the sharp outline of death; between the half-closed eyelids the darkened blue eyes looked out vacantly. The thick, fair hair, spotted with blood, flowed in disordered waves over the white pillow; the numerous rings on the dead hands blazed and glittered with hard brilliance in the electric light.

It was these costly jewels on the murdered girl's hands which prompted the question which sprang to the detective's lips:

"Did the murderer take anything?" he asked. "Has anything been missed?"

"No," said Miss Heredith. "Nothing has been taken."

"Mrs. Heredith had more jewellery than this, I suppose?" pursued the detective. "Brooches and necklaces, and that kind of thing. Where were they kept?"

"Mrs. Heredith's jewel-case is downstairs, in the safe in the library," replied Miss Heredith. She did not feel called upon to add the additional information that she had taken it there herself, and locked it up, not half an hour before.

Detective Caldew made a mental note of the fact that the motive for the crime was not robbery, unless, indeed, the murderer had become flurried, and fled. His eye, glancing round the room, was attracted by the window curtains, which were stirring faintly. He flung them back, and saw the open window.

"How long has this window been open?" he asked.

Miss Heredith gave her reasons for believing that the window was closed when she left Violet to go downstairs to the dining-room. Caldew listened thoughtfully, and nodded his head in quick comprehension when she added the information that the bedroom window was nearly twenty feet from the ground.

"You think the murderer did not jump out of the window," he said. "The more important point is, did he get in that way? It is not a difficult matter to scale a wall to reach a window if there is any sort of a foothold. It is a point I will look into afterwards."

He tried the window catch, and then walked about the room, examining it closely. His quick, eager eyes, looking about in every direction, were caught by something glittering on the carpet, close to the bed. He glanced at his companions. As a detective, he had long learnt the wisdom of caution in the presence of friends and relatives.

"I should like to be left alone in the room in order to examine it more thoroughly," he briefly announced.

When Miss Heredith and Musard had left the room he locked the door behind them, and, kneeling down by the bedside, disentangled a small shining object almost concealed in the thick green texture of the carpet. It was a trinket like a bar brooch, with gold clasps. The bar was of transparent stone, clear as glass, with a faint sea-green tinge, and speckled in the interior with small black spots. Caldew had never seen a stone like it. The frail gold of the setting suggested that it was not of much intrinsic value, but it was a pretty little trinket, such as ladies sometimes wear as a mascot. Caldew reflected that if it were a mascot it was by no means certain that the owner was a woman. Many young officers took mascots to the front for luck.

As he turned it over in his hand he observed some lettering on the underside. He examined it curiously, and saw that an inscription had been scratched into the stone in round, irregular handwriting—obviously an unskilled, almost childish effort. Holding the brooch closer to the light, he was able to decipher the inscription. It consisted of two words—"Semper Fidelis."

It seemed to Caldew that the inscription rather weakened the correctness of his first impression that the trinket had been worn as a feminine mascot. He doubted very much whether any modern woman would cherish a mid-Victorian sentiment like "Always Faithful." On the other hand, many men might. His experience as a detective had led him to the belief that men were more prone to such sentiments than the other sex, though their conduct rarely accorded with their protestations and temporary intentions.

Struck by a sudden thought, he dropped the trinket back on the carpet. It was just visible in the thick pile.

"A good idea!" he murmured, as he rose to his feet. "I'll watch this room to-night."

As he stood there, speculating on the possibility of the owner of the trinket returning to the room to search for it, he was interrupted by a low tap at the door. He walked across and opened it. Tufnell stood outside, grave and composed.

"Mr. Musard would like to see you in the library," he said.

His tone was even and almost deferential, but the detective's watchful eyes intercepted a fleeting glance cast by the butler over his shoulder in the direction of the still figure on the bed.

"Very well, I will see him," said the detective.

"I will take you to him, if you will come with me." The butler preceded him along the passage with noiseless step, and Caldew followed him, deep in thought.

The butler escorted him to the library, and entered after him. Musard was in the room alone, standing by the fireplace, smoking a cigar. He looked up as Caldew entered.

"I have just learnt something which I think you ought to know," he said. "The information comes from Tufnell. He tells me that while he was going around the house this afternoon he found the outside door of the back staircase unlocked."

"Do you mean the door at the bottom of the staircase in the left wing?" asked Caldew.

"Precisely."

"I understood from Miss Heredith that this door was always kept locked."

"So it is, as a rule. It was only by chance that the butler discovered this evening that it had been unlocked. You had better explain to the detective, Tufnell, how you came to find it unfastened."

"I was going round by the back of the house this evening," said the butler, coming forward. "As I passed the door I tried the handle. To my surprise it yielded. I opened the door, and found that the key was in the keyhole, on the other side. I locked the door, and took the key away."

"What time was this?" inquired Caldew.

"A little before six—perhaps a quarter of an hour."

"Is it your custom to try this door every night?"

"Oh, no, it is not necessary. The door is always kept locked, and the key hangs with a bunch of other unused keys in a small room near the housekeeper's apartments, where a number of odds and ends are kept."

"When was the last time you tried the door?"

The butler considered for a moment.

"I cannot rightly say," he said at length. "The door is never used, and I rarely think of it."

"Then, for all you know to the contrary, the key may have been in the door for days, or weeks past."

"Why, yes, it is possible, now that you come to mention it," said the butler, with an air of surprise, as though he had not previously considered such a contingency.

"The key had been taken off the bunch?"

"Yes."

"Do the servants know where the key is kept?"

"Some of the maidservants do. The back staircase is occasionally opened for ventilation and dusting, and the maid who does this work gets the key from the housekeeper."

"Who has charge of the room where the keys are kept?"

"Nobody in particular. It is really a sort of a lumber-room. The housekeeper has charge of the keys."

"Thank you; that is all I wish to know."

The butler left the room, and Caldew looked up, to encounter Musard's eyes regarding him.

"Do you think this has anything to do with the murder?" Musard asked.

Caldew hesitated for a moment. It was on the tip of his tongue to reply that he attached no importance to the butler's statement, but professional habits of caution checked his natural impulsiveness.

"I want to know more about the circumstances before advancing an opinion," he replied. "Tufnell's story was rather vague."

"In what respect?"

"In regard to time. The door may have been left unlocked for days."

"Who would unlock it?" replied Musard. "The inference, in view of what has happened, seems rather that the door was unlocked to-day, and Tufnell stumbled upon the fact by a lucky chance—by Fate, if you like. At least it looks like that to me."

"And the murderer entered by the door?"

"Yes."

"I think that is assuming too much," said Caldew. He had no intention of pointing out to his companion that such an assumption overlooked the fact that Tufnell's discovery, and the locking of the door, had not prevented the crime and the subsequent escape of the murderer.

He turned to leave the room, but Musard was in a talkative mood. He offered the detective a cigar, and kept him for a while, chatting discursively. Caldew was in no humour to listen. His mind was full of the problems of this strange case, and he was anxious to return upstairs. He took the first opportunity of terminating the conversation and leaving the room.

It was his intention to conceal himself in one of the wardrobes of the bedroom in the hope that the owner of the trinket he had found would return in search of it. As he reached the landing he was surprised to see that the door of the murdered woman's bedroom was wide open, although he remembered distinctly that he had closed it when he left the room to accompany the butler downstairs. With a quickly beating heart he hurried across the room to the spot where he had left the trinket. But it was gone.

CHAPTER VII

It was the morning after the murder, and five men were seated in the moat-house library. One of them attracted instant attention by reason of his overpowering personality. He was a giant in stature and build, with a massive head, a large red face from which a pair of little bloodshot eyes stared out truculently, and a bull neck which was several shades deeper in colour than his face. He was Superintendent Merrington, a noted executive officer of New Scotland Yard, whose handling of the most important spy case tried in London during the war had brought forth from a gracious sovereign the inevitable Order of the British Empire. Merrington was known as a detective in every capital in Europe, and because of his wide knowledge of European criminals had more than once acted as the bodyguard of Royalty on continental tours, and had received from Royal hands the diamond pin which now adorned the spotted silk tie encircling his fat purple neck.

The famous detective's outlook on life was cynical and coarse. The cynicism was the natural outcome of his profession; the coarseness was his heritage by birth, as his sensual mouth, blubber lips, thick nose, and bull-neck attested. It was a strange freak of Fate which had made him the guardian of the morals of society and the upholder of law and order in a modern civilized community. By temperament and disposition he belonged to the full-blooded type of humanity which found its best exemplars in the early Muscovite Czars, and, if Fate had so willed it, would have revelled in similar pursuits of vice, oppression, and torture. As Fate had ironically made a police official of him, he had to content himself with letting off the superfluous steam of his tremendous temperament by oppressing the criminal classes, and he had performed that duty so thoroughly that before he became the travelling companion of kings his name had been a terror to the underworld of London, who feared and detested his ferocity, his unscrupulous methods of dealing with them, and his wide knowledge of their class.

He was a recognized hero of the British public, which on one occasion had presented him with a testimonial for his capture of a desperado who had been terrorizing the East End of London. But Merrington disdained such tokens of popular approval. He regarded the public, which he was paid to protect, as a pack of fools. For him, there were only two classes of humanity—fools and rogues. The respectable portion of the population constituted the former, and criminals the latter. He had the lowest possible opinion of humanity as a whole, and his favourite expression, in professional conversation, was: "human nature being what it is...." He was still a mighty force in Scotland Yard, although he had passed his usefulness and reached the ornamental stage of his career, rarely condescending to investigate a case personally.

His present visit to the moat-house was one of those rare occasions, and was due to the action of Captain Stanhill, the Chief Constable of Sussex, who was seated near him. Captain Stanhill was a short stout man, with a round, fresh-coloured face, and short sturdy legs and arms. He wore a tweed coat of the kind known to tailors as "a sporting lounge," and his little legs were encased in knickerbockers and leather gaiters, which were spattered with mud, as though he had ridden some distance that morning. He was a very different type from Superintendent Merrington—a gentleman by birth and education, a churchman, and a county magnate. He never did anything so dangerous as to think, but accepted the traditions and rules of his race and class as his safe guide through life. Like most Englishmen of his station of life, he was endowed with just sufficient intelligence to permit him to slide along his little groove of life with some measure of satisfaction to himself and pleasure to his neighbours. He was a sound judge of cattle and horses, but of human nature he knew nothing whatever, and his first act, on being informed of the murder at the moat-house, was to ring up Scotland Yard and request it to send down one of its most trusted officials to investigate the circumstances. In reply to this call for assistance, Superintendent Merrington, not unmindful of the county standing and influence of the Herediths, had decided to investigate the case himself, and had brought with him two satellites—a finger-print expert who was at that moment paring his own finger-nails with a pocket-knife as he stared vacantly out of the library window, and an official photographer, who was upstairs taking photographs in the death chamber.

Seated near the finger-print expert was a police official of middle-age, Inspector Weyling, of the Sussex County Police. He was a saturnine sort of man, with a hooked nose, a skin like parchment, and a perfectly bald sugar-loaf head, surmounted at the top by a wen as large as a duck-egg. His deferential attitude and obsequious tone whenever Superintendent Merrington chose to address a remark to him indicated that he had a proper official respect for the rank and standing of that gentleman. Inspector Weyling was merely a police official. He had no personal characteristics whatever, unless a hobby for breeding Belgian rabbits, and a profound belief that Mr. Lloyd George was the greatest statesman the world had ever seen, could be said to constitute a temperament.

The fifth man was Detective Caldew, who had just completed a narrative of the events of the previous night for the benefit of his colleagues, but more especially for Superintendent Merrington, in whose hands lay the power of directing the investigations of the crime. It was by no wish of Detective Caldew that Superintendent Merrington had been brought into the case. Caldew thought when the county inspector arrived and found a Scotland Yard man at work he would be only too glad to allow him to go on with the case, and he anticipated no difficulty in obtaining the consent of his official superiors at Scotland Yard to continuing the investigations he had commenced. But Inspector Weyling, when notified of the crime by Sergeant Lumbe, had telephoned to the Chief Constable for instructions. The latter, distrustful of the ability of the county police to bring such an atrocious murderer to Justice, had begged the help of Scotland Yard, with the result that Superintendent Merrington and his assistants appeared at the moat-house in the early morning before the astonished eyes of Caldew, who was taking a walk in the moat-house garden after a night of fruitless investigations.

In the arrival of Merrington, Caldew saw all his fine hopes of promotion dashed to the ground. He was by no means confident that Merrington would permit him to take any further share in the investigations, but he was quite certain that if he did, and the murderer was captured through their joint efforts, very little of the credit would fall to his share when such a famous detective as Merrington was connected with the case. Merrington would see to that.

Caldew, in his narration of the facts of the murder, laid emphasis on the mysterious nature of the crime, in the hope that Merrington might deem it wiser to return to London and leave him in charge of the case, rather than risk a failure which would greatly damage his own reputation. Merrington listened to him gloomily. He fully realized the difficult task ahead of the police, and his temper was not improved in consequence.

"Apparently the murderer has got clean away without leaving a trace behind him?" he said.

"Yes."

"No sign of any weapon?"

"No."

"Anything taken?"

"No. Miss Heredith says nothing was taken from the room, and nothing is missing from the house."

"The motive was not robbery then," remarked Captain Stanhill.

"It may have been," responded Merrington. "Caldew says the first intimation of the crime was the murdered woman screaming. The scream was followed in a few seconds by the revolver shot. If she screamed when she saw the murderer enter her room, he may well have feared interruption and capture, and bolted without stealing anything."

"Why did he murder her, then, in that case?" asked Captain Stanhill.

"To prevent subsequent identification. Many burglars proceed to murder for that reason. I know plenty of old hands who would commit half a dozen murders rather than face the prospect of five years' imprisonment. I do not say that burglary was the motive in this case, but we must not lose sight of the possibility."

"It seems a strange case," murmured Inspector Weyling absently. He was thinking, as he spoke, of his rabbits, and wondering whether his wife would remember to give the lop-eared doe with the litter a little milk in the course of the morning.

"It's a very sad case," said Captain Stanhill. "Poor young thing!" The Chief Constable was a human being before he was a police official, and his face showed plainly that he was stricken with horror by the story of the crime.

"It's a damned remarkable case," exclaimed Merrington, in his booming voice. "I do not remember its parallel. An English lady is murdered in her home, with a crowd of people sitting at dinner in the room underneath, and the murderer gets clean away, without leaving a trace. No weapon, no finger-prints or footprints, and no clue of any kind."

Caldew had been hoping to get an opportunity of telling Merrington privately about the missing trinket, but he realized that he was not doing his duty by delaying the explanation.

"There was something which might have helped us as a clue," he said. "Last night, while I was examining Mrs. Heredith's bedroom, I saw a small trinket lying on the floor near the bedside."

"What sort of a trinket?" asked Merrington.

"A small bar brooch."

"Where is it?"

"I do not know," replied Caldew awkwardly. "I left it where I saw it, hidden in the carpet, thinking it possible that the person who had lost it might return in search of it, but while I was downstairs it disappeared."

"It is rather strange," said Merrington thoughtfully. "I am not inclined to think there is anything in it to help us," he added, after a moment's consideration. "Still, I will look into it later. Why did you leave the trinket in the room, Caldew?"

"I thought it possible that if the owner had anything to do with the crime he—or she—might return for it," said Caldew. "So I left it where I found it, and watched the room from the end of the passage."

"A murderer doesn't go about wearing a cheap trinket, and, if he did, he wouldn't risk his neck coming back to look for it. The brooch was more likely dropped by one of the maidservants, who picked it up again."

"Would a girl go into a room where there was a dead body?"

"A country wench would. English countrywomen have pretty strong nerves. You ought to know that. But why did you leave the room if you expected the owner of the trinket to return in search of it?"

"I was called downstairs to see Mr. Musard. An unused outside door which is generally kept locked was discovered unlocked by the butler before the murder was committed. As the door opens on a staircase leading to the left wing, Mr. Musard thought the butler's discovery had some bearing on the crime."

"He thought the murderer may have entered the house that way? Such a theory would suggest that one of the servants is implicated."

"Yes; but I do not agree with Mr. Musard."

"What is your own opinion?"

"I think the key must have been left in the door by one of the servants—perhaps some days ago. The fact that the butler locked the door when he found it unfastened did not prevent the murder being committed, or the murderer escaping afterwards."

"The murderer may have entered by the door before the butler discovered that it had been unlocked, and then concealed himself inside the house awaiting an opportunity to commit the crime."

"In that case, he would have tried to escape the same way, but it is quite certain that he did not do so. Mr. Musard says that the staircase was the first place to be searched when the guests rushed upstairs. If the murderer had gone that way he would have found the door at the bottom locked, and the key removed, and he must have been caught before he could get back upstairs."

"There's something in that," said Merrington. "But how do you account for the door being unlocked in the first instance?"

"The servants know where the key is kept. One of the maids may have taken it to steal out of the house that way to keep an appointment with a sweetheart, and forgotten all about it when she returned. The back staircase and entrance are never used by the members of the household, and the key, which was inside the door, may have been there for days without being noticed. Tufnell admits that it was only by chance he tried the door yesterday. He had not tried it for weeks before."

"I'll have a look at this door later. And now, we had better get to work. We have got to catch this murderer pretty quickly, or the press and the public will be up in arms. He's had too long a start already. You must make up your mind for considerable public indignation about that, Caldew."

"I do not see how I can be held responsible for the murderer getting away," said Caldew, in an aggrieved tone. "He had his start before I arrived. I did everything that I could. I searched the house inside and out, and Sergeant Lumbe has been scouring the country-side since daybreak looking for suspicious characters."

"I am not blaming you, Caldew," responded Merrington, but his voice suggested the reverse of his words. "I am merely pointing out to you the way the British public will look at it. They will say, 'Here is a young wife murdered in the bosom of her home and family, and the murderer gets right away. What do we pay the detective force for? To let murderers escape?' Mark my words, if we don't lay our hands on this chap quickly, we'll have the whole of the London press howling at our heels like a pack of wolves. Half a dozen special reporters travelled down in the train with me and pestered me with questions all the way. They are coming along here later for a statement for the evening editions. But never mind the journalists—let us get to work without further loss of time. Have you made a list of all the guests who have been stopping in the house?"

"Not yet. Here is a sketch plan of the moat-house interior and the grounds which you may find useful."

"Thanks. You had better prepare a list of the guests before they leave. They are sure to get away as fast as possible, and we may want to interview some of them later on. Now we had better have a look at the body."

They went upstairs to the bedroom. There they found a young man, with a freckled face and a snub nose, packing up a photographic apparatus. He was the photographer, and he had been taking photographs of the dead body.

"Finished?" inquired Merrington. "That's right. Then you and Freeling had better return to London by the next train—you'll be wanted in that Putney case."

The photographer and the finger-print expert left the room together, and Merrington walked across to the bed. He drew away the sheet which covered the dead girl, and bent over the body, examining it closely, but without touching it.

"The corpse has not been moved, I suppose?" he remarked to Caldew, who was standing beside him.

"Not since I arrived. But she may not have been shot in that position. She lived some minutes afterwards, and may have moved slightly—not much, I should say, for there are no marks of bloodstains on any other part of the bed."

Merrington nodded. He was looking at the bullet wound, which was plainly visible through a burnt orifice in the rest-gown which the dead girl was wearing. The wound was a circular punctured hole in the left breast, less than the size of a sixpenny piece.

"The wound has been washed," he observed. "Was that done by the police surgeon?"

"The police surgeon has not been here. The corpse was examined by the village medical man, Dr. Holmes."

"I should like to see him. Where is he to be found?"

"He will be here in the course of the morning. He is attending young Heredith, who is suffering from the shock. The doctor fears brain fever."

"When he comes I want to see him. It is idle speculating about the cause of death in the absence of a doctor. Death in this case appears to have been due to hæmorrhage. Apparently the murderer aimed at the heart and missed it, and the shot went through the lungs. The shot was fired at very close range too—look how the wrapper is burnt! Any sign of the bullet, Caldew?"

"I found none."

"Well, we shall have to wait for the doctor to clear up these points."

His trained eyes swept round the bedroom, taking stock of every article in it. He next carefully examined the door, and the lock on it.

"The door was open when the others came upstairs, you said, Caldew?"

"Yes—about half open."

"That accounts for the scream and the shot being heard so plainly downstairs. It also suggests that the murderer fled very hurriedly, leaving the door open behind him."

"It seems to me more likely that he escaped by the window, even if he did not enter that way. Miss Heredith, who was the last inmate of the household to see Mrs. Heredith alive, thinks that the window was closed when she was in the room before dinner."

Merrington walked over to the window and examined it, testing the lock and looking at the sill.

"Does Miss Heredith say that the window was locked, or merely closed, when she was in the room?" he asked.

"She cannot say definitely. She thinks it was closed because the air was heavy, and she knew that Mrs. Heredith disliked having her bedroom window open."

Merrington shrugged his shoulders contemptuously.

"A woman's fancies are not much to build a theory upon," he said. "Have you any other reason for thinking that the murderer may have escaped by this window?"

"Yes. After the shot was fired the guests rushed upstairs immediately, and the murderer would have run into them if he had attempted to escape downstairs."

"Is there no other means of escape from the wing except by the staircase?"

"There is the back staircase I told you of, at the end of the corridor. That staircase is never used. The door is kept locked, and the key hangs in a room downstairs. It was the door at the bottom of this staircase which was found unlocked by the butler yesterday evening."

"I'll have a look at it, and then we'll go downstairs. I want to see this bedroom window from outside."

They left the bedroom and proceeded to the end of the corridor, where Caldew pointed out the door at the top of the staircase. Merrington opened it, and went down the stairs. He reappeared after the lapse of a few minutes with dusty hands and cobwebs on his clothes.

"The murderer didn't get in that way," he said. "On the face of it, it seems a plausible theory to suggest that he entered by the locked door and hid himself somewhere in this wing, and escaped after committing the murder by jumping through the bedroom window. But it is impossible to get over your point that if he had entered by the door he would have tried to escape by the same means, not knowing that the door had been locked in the meantime. To do that he must have traversed the corridor twice and gone down and up these back stairs while the guests were coming up the other stairs. He couldn't have done it in the time. He would have been caught—cut off before he could get back. Look at this steep flight of stairs and the length of the corridor! That disposes of the incident of the door. Whoever unlocked it was not the murderer."

Merrington retraced his steps along the corridor. As he walked, his eyes roved restlessly over the tapestry hangings and velvet curtains, and took in the dark nooks and corners which abound in old English country-houses.

"Plenty of places here where a man might hide," he muttered, in a dissatisfied voice.

At the head of the front staircase he paused, and looked over the balusters, as though calculating the distance to the hall beneath. Then he descended the stairs.

It still wanted half an hour to breakfast time. There was no sign of anybody stirring downstairs except a fresh-faced maidservant, who was dusting the furniture in the great hall. She glanced nervously at the groups of police officials, and then resumed her dusting. Merrington strode across to her.

"What is your name, my dear?" he asked, in his great voice.

"Milly Saker, sir."

"Very well, Milly. I'll come and have a talk with you presently—just our two selves."

The girl, far from looking delighted at this prospect, backed away with a frightened face. Merrington strode on through the open front door, and turned towards the left wing.

It was a crisp autumn morning. The early sunshine fell on the hectic flush of decay in the foliage of the woods, but a thin wisp of vapour still lingered across the moat-house garden and the quiet fields beyond. Merrington kept on until he reached the large windows of the dining-room, which opened on to the terraced garden.

"That's Mrs. Heredith's window," he said, pointing up to it. "Her bedroom is directly over the dining-room. If the murderer escaped by the window he must have dropped on to this gravel path."

"It is a pretty stiff drop," said Captain Stanhill, measuring the distance with his eye.

"Oh, I don't know," replied Merrington. "He'd let himself down eight feet with extended arms, and that would leave a drop of only ten feet or thereabouts—not much for an athletic man. But if he dropped he must have left footprints."

"There are none. I have looked," said Caldew.

The information did not deter Merrington from examining the path anew. He got down on his hands and knees to scrutinize the gravel and the grass plot more thoroughly.

"Nothing doing here either," he said as he scrambled to his feet. "There are neither footprints nor marks such as one would expect to find if a man had dropped out of the window. What are you looking at, Weyling?"

In reply Inspector Weyling made his first and only contribution towards the elucidation of the crime.

"Could not the murderer have climbed up to the bedroom by that creeper?" he asked, pointing to a thin trail of Virginia creeper which stretched up the wall almost as high as the window.

Merrington tested the frail creeper with his great hand. His sharp tug detached a mass of the plant from the brickwork.

"Not likely," he replied. "It might bear the weight of a boy or a slender girl, but not of a man. What do you think, Caldew?"

Caldew nodded without speaking. Weyling's remark had started a train of thought in his mind, but he had no intention of revealing it to a man who plainly did not intend to confer with him on equal terms, or disclose his own theory of the murder—if he had formed one.

"Let us get inside again," said Merrington, in his masterful way.

He turned back towards the house, and the others followed.

CHAPTER VIII

As they reached the library again a small silver clock on the mantelpiece gave a single chime. Merrington looked at it, and then glanced at his watch.

"Half-past eight!" he said. "That clock is five minutes slow—by me. The people who have been staying here will go off after breakfast. Visitors always leave a house of trouble as soon as possible—like rats deserting a sinking ship. The thing is to question as many as we can get hold of before they go. As some of them knew Mrs. Heredith before her marriage, we may elicit something about her or her antecedents which will throw some light on the motive for the crime."

"I do not think Sir Philip will care to have his guests questioned," remarked Captain Stanhill doubtfully. "They must be all well-connected and very respectable people, or they would not have been invited here."

"There have been very respectable and highly connected murderers before to-day, Captain Stanhill, as no doubt you are aware," rejoined Merrington caustically.

"The guests were all downstairs in the dining-room at the time the murder was committed," said Caldew. "Miss Heredith told me so herself."

"I am aware of that fact also," retorted Merrington sharply. "Nevertheless, they must be seen. We cannot afford to throw away a chance."

"It is a delicate and awkward business," murmured the Chief Constable.

"It will be a delicate and awkward business for us if we don't lay our hands on this criminal," responded Merrington. "Sir Philip Heredith, with his influence and connections, will be able to make it pretty hot for Scotland Yard and the County Police if the murderer of his son's wife is allowed to escape. You'd better take the job in hand at once, Caldew. Weyling can go with you and help. See as many of the guests as you can—especially the ladies—and get what you can out of them. But I'd be glad if you'd first ask Miss Heredith to grant me an interview before breakfast. Don't send a servant, but see her yourself."

Caldew left the room to undertake the investigations allotted to him, and Weyling followed him with a startled expression of face. He felt overweighted by the magnitude of the task which had been thrust upon him, and doubted his ability to discharge it properly.

"Miss Heredith will be able to give us more information than Sir Philip," remarked Merrington in a friendly tone to Captain Stanhill, as the door closed behind the subordinate officials. "A woman is generally more observant than a man—particularly if anything underhand has been going on."

Captain Stanhill cast a puzzled glance at his companion. As a simple-minded English gentleman he was quite unable to penetrate the obscurity of expression which masked the meaning of the last remark. Merrington caught the look, but had formed too poor an opinion of his companion's understanding to explain himself further. Besides, he liked mystifying people.

"I'm going to put the servants through their facings straight away," he continued. "If there is anything to be learnt we are more likely to find it out from them than the guests. Trust the backstairs for knowing what's going on upstairs! Servants want skilful handling, though. You've got to know when to bully and when to coax. Half measures are no good with them."

Captain Stanhill did not reply. He wandered round the spacious library, glancing at the rows of books in their oaken shelves. Superintendent Merrington, while awaiting the arrival of Miss Heredith, drew forth the plan of the moat-house which Caldew had sketched, and studied it closely.

The moat-house had only two stories, but it was a rambling old place and covered a considerable area of ground, facing three sides of the county. The principal portion, consisting of the old house which had been burnt down and rebuilt, faced the north. The two wings had been added later.

The front door opened into a spacious entrance hall which in former times had been the dining-room. At the end of the hall was the grand staircase, adorned by statues, armour, and the Heredith arms carved in panels. The principal rooms, with the exception of the dining-room, were all on the ground floor of the main building, but corridors led off the entrance hall to the newer wings at each side, extending on the right side to the billiard room, conservatory, greenhouses, and orangery, and on the left side to the dining-room, Miss Heredith's private sitting-room, and Sir Philip's study.

Merrington carefully studied the arrangements of this wing, as depicted on Caldew's sketch plan. The upper portion was reached by a staircase which opened off the corridor almost opposite the dining-room door, and ran, with one turning, to a landing which was only a few feet away from the door of the bedroom in which Mrs. Heredith was murdered. Next to this room was a dressing-room, and a spare bedroom. The remainder of the wing consisted of two bathrooms, a linen room, and Miss Heredith's bedroom, which was at the south end of the wing. The rooms all faced the west side of the house, and were lit by windows opening on the terraced gardens. They were entered by a corridor which ran the whole length of the wing, terminating in the door which opened on the unused back staircase.

Before Merrington had finished his scrutiny of the plan, the door opened, and Miss Heredith entered the library. She looked pale and worn, and there were dark rings under her eyes which suggested a sleepless night. But her face was composed, though grave.

Captain Stanhill advanced and shook hands with her, uttering a few words of well-bred sympathy as he did so, and then introduced Superintendent Merrington.

"Superintendent Merrington has been kind enough to come down from Scotland Yard at my request to give us the benefit of his skill in investigating this terrible crime," he said simply.

"I desired an interview with you in order to ask a few questions," said Merrington, coming to the point at once.

Miss Heredith bowed.

"Were all the blinds down in the dining-room last night during dinner?" asked Merrington.

Captain Stanhill looked quickly at his colleague. He failed to see the purpose of the question.

"I think so," replied Miss Heredith, after a moment's reflection. "I cannot say for certain, as I was out of the room during the latter portion of the dinner, but I can easily ascertain." She touched a bell, which was answered by a maidservant. "Tell Mr. Tufnell I wish to speak to him," she said.

The girl went away, and Tufnell appeared a moment afterwards.

"Were the blinds all drawn in the dining-room during dinner last night, Tufnell?"

"Yes, ma'am. I pulled them down myself before sounding the gong."

"Thank you, Tufnell."

"I understand that you were not present at the dinner table when the shot was fired?" said Merrington when the butler had left the room.

"No, I was not."

"May I ask why you left the table?"

The question was put suavely enough, but a half-uttered protest from Captain Stanhill indicated that he, at least, realized the sting contained within it. But Miss Heredith, looking at Merrington with her clear grey eyes, replied calmly:

"I was called out of the room to speak to our chauffeur. He had been ordered to have an extra vehicle in readiness to convey our guests to an evening entertainment, and he wished to consult me about it."

"Why did you not return to the dining-room?"

"Because dinner was nearly finished when I left the room."

"Where were you when the shot was fired?"

"I was on the stairs, on the way to my room when I heard the scream. I was hastening back to the dining-room as quickly as possible, but before I reached it the shot rang out."

"Surely these questions are unnecessary, Merrington," exclaimed Captain Stanhill. "Anyone would think—I mean that there is not the slightest idea in our minds that Miss Heredith—at least, I meant to say—" Captain Stanhill floundered badly as he realized that his remarks were capable of a terrible interpretation which he did not intend, and broke off abruptly.

"I am very glad that Superintendent Merrington has asked these questions," said Miss Heredith coldly.

Merrington bowed a grim acknowledgment. He had still many questions he wanted to ask Miss Heredith, and he proceeded to put them in his own masterful way, very much as though he were examining a witness in the police court, Captain Stanhill thought, but in reality with a courtesy and consideration quite unusual for him. It was his best manner; his worst, Captain Stanhill was to see later. As a matter of fact, it was impossible for Merrington to be gentle with anybody. He had spent so many years of his life probing into strange stories and sinister mysteries that he had insensibly come to regard the world as a larger criminal court, made up of tainted and adverse witnesses, whom it was his privilege to cross-question.

He questioned Miss Heredith searchingly about the young bride. According to an eminent expert in jurisprudence, the tendency to believe the testimony of others is an inherent instinct implanted in the human breast by the Almighty. If that be so, it is to be feared that the seed had failed to germinate in Merrington's bosom, for his natural tendency was to look upon his fellow creatures as liars, particularly when they were of good social standing, with that hatred of notoriety which is characteristic of their class. Merrington had this fact in his mind as he interrogated Miss Heredith closely about the circumstances of her nephew's marriage. He hoped to extract from her something which her English pride might lead her to conceal, something which might throw a light on the motive for the murder.

Miss Heredith answered him with a frankness which even Merrington grudgingly realized left nothing to be desired. She was, apparently, only too anxious to help the police investigations to the best of her ability. But what she had to tell amounted to very little. Her first knowledge of her nephew's intention to marry was contained in a letter written home some four months before, in which he announced his engagement to a young lady engaged in war work in a London Government office. A month later came the news that he was married, and was bringing his young bride to the moat-house. The young couple arrived a week after the receipt of the second letter. They were welcomed home, and settled down to country life in the old place. Phil left his post in the War Office, and busied himself in looking after the estate. He was very fond of his young wife, but it was obvious from the first that Violet found the quiet country existence rather dull after her London life. She knew nobody in Sussex except Mrs. Weyne, the author's wife, who had been an acquaintance of hers in London years before, and she did not seem to care much for the county people who visited the moat-house. She received letters from girl friends in London, and sometimes read extracts from them at the breakfast table, but her life, on the whole, was a secluded one. It was in order to brighten it that Phil suggested a house party. The guests consisted principally of Violet's and Phil's London friends and acquaintances.

"Do you know the names of these girl friends who used to write to her?" asked Merrington.

Miss Heredith replied that she did not.

"I suppose her husband would know them?"

"It is quite impossible to question my nephew," said Miss Heredith decisively. "He is dreadfully ill."

Merrington nodded in a dissatisfied sort of way. He was aware of Phil's illness, and his suspicious mind wondered whether it had been assumed for the occasion in order to keep back something which the police ought to know. His thick lip curled savagely at the idea. If these people tried to hide anything from him in order to save a scandal, so much the worse for them. But that was something he would go into later.

The next questions he put to Miss Heredith were designed to ascertain what she thought of the murder, whether she had any suspicions of her own, and whether there was any reason for suspecting Miss Heredith herself. At that stage of the inquiry it was Merrington's business to suspect everybody. He could not afford to allow the slightest chance to slip. His object was to get at the truth; to weigh each particle of supposition or evidence without regard to the feelings or social position of the witness.

The case so far puzzled him, and Miss Heredith's answers to his questions revealed little about the murder that he had not previously known. The only additional facts he gleaned related to the murdered girl's brief existence at the moat-house; of her earlier history and her London life Miss Heredith knew nothing whatever. Merrington made some notes of the replies in an imposing pocket-book, but he was plainly dissatisfied as he turned to another phase of the investigation.

"Were all your guests in the dining-room at the time the scream and the shot were heard?" he asked.

"They were all there when I left the room. The butler can tell you if any left afterwards."

"I will question Tufnell on that point later. No, on second thoughts, it will be better to settle it now. I attach importance to it."

Tufnell was recalled to the room, and, in reply to Superintendent Merrington's question, stated that none of the guests left the dining-room before the shot was fired. Tufnell added they were all interested in listening to a story that Mr. Musard was telling. Having imparted this information the butler returned to the breakfast room, overweighted with the responsibility of superintending the morning meal in his mistress's absence.

"Is this Musard the jewel expert of that name?" asked Merrington.

"Our guest is Mr. Vincent Musard, the explorer," replied Miss Heredith coldly.

"The same man." Merrington made another minute note in his pocket-book, and continued, "May I take it, then, that all your guests who were staying here were assembled in the dining-room at the time the murder was committed?"

"Yes; except one who left during the afternoon."

"Who was that?"

"Captain Nepcote, a friend of my nephew's. He received a telegram recalling him to the front, and returned to London by the afternoon train."

Merrington made a note of this in his pocket-book with an air of finality, and asked Miss Heredith to see that the servants were sent to the library one by one, to be questioned. Miss Heredith said she would arrange it with the housekeeper, and was then politely escorted to the door by Captain Stanhill.

The next few hours were educative for Captain Stanhill. Although he was Chief Constable of Sussex, he took no part in the proceedings, but sat at the table like a man in a dream, living in a world of Superintendent Merrington's creation—a world of sinister imaginings and vile motives, through which stealthy suspicion prowled craftily with padded feet, seeking a victim among the procession of weeping maids, stolid under-gardeners, stable hands, and anxious upper servants who presented themselves in the library to be questioned. But it seemed to Captain Stanhill that though the women were flustered and the men nervous, they knew nothing whatever about the atrocious murder which had been committed a few hours before in the room above their heads. Merrington also seemed to be aware that he was getting no nearer the truth with his traps, his questions, and his bullying, and he grew so angry and savage as the day wore on that he reminded Captain Stanhill of a bull he had once seen trying to rend a way through a mesh. As the morning advanced, Merrington's face took on a deeper tint of purple, his fierce little eyes grew more bloodshot, and between the intervals of examining the servants he mopped his perspiring head with a large handkerchief.

The significance of one fact he did not realize until afterwards. The last of the inmates of the moat-house to come to the library was the housekeeper, Mrs. Rath, who presented herself at his request in order to acquaint him with the details of the domestic management of the household. Mrs. Rath entered the room with a nervous air. Her white face contrasted oddly with her black dress, and her hands shook slightly, in spite of her effort to appear composed. Merrington stared at her careworn face and hollow grey eyes with the perplexed sensation of a man who is confronted with a face familiar to him, but is unable to recall its identity.

"Where have I seen you before?" he blurted out.

The housekeeper raised frightened eyes, ringed with black, to his truculent face, but dropped them again without speaking. Merrington did not repeat his question. He did not imagine the housekeeper knew anything about the murder, but it was a mistake to put a witness on her guard. It was in quite a different tone that he thanked Mrs. Rath for sending the servants to the library, and asked her to describe the household arrangements of the previous night. Mrs. Rath, who had been palpably nervous after his first question, became reassured and more at her ease, and answered him intelligently.

"And where were you at the time of the murder, Mrs. Rath?" pursued Merrington, when he had drawn forth these details.

"I was in my sitting-room."

"Did you hear the scream and the shot?"

"I heard the scream, but not the shot."

"How was that?"

"My sitting-room is a long way from Mrs. Heredith's room. Perhaps that is the reason."

Merrington looked at the position of the housekeeper's room on the plan of the moat-house which Caldew had drawn. As she said, it was a considerable distance to her room, which was in the old portion of the house, near the rear, and on the ground floor.

"Were you alone in your room?" he asked.

"No. My daughter was sitting with me."

To a quick ear it may have seemed that the answer was a trifle long in coming.

Merrington shook his head irritably. Really, it seemed impossible to reach the end of the people who were in this infernal moat-house at the time of the murder.

"Does your daughter live with you here?" he asked.

"Oh, no. She came to see me yesterday afternoon, and stayed all night because she missed her train back after—after the tragedy."

"Is she here now?"

"No. She went away by an early train. She is employed as a milliner at Stading, the market town, which is ten miles away."

"She lives there, I suppose?"

"Yes. She lives in."

"Who is her employer?"

"Mr. Closeby, the draper. Daniel Closeby and Son is the name of the firm."

Merrington made another note in his pocket-book. It sounded plausible enough, but the girl must be added to the lengthening list of people in the case who would have to be seen.

"I think that is all I need detain you for, Mrs. Rath," he said.

The housekeeper lingered to inquire when the gentlemen would like their lunch. Merrington, who had breakfasted early and passed an arduous morning, replied bluntly that it could not be too soon to please him.

"I'll have it served in the small breakfast-room in a quarter of an hour," said Mrs. Rath, hurrying away.

Her whole bearing, as she departed, indicated such an air of irrepressible relief at having passed through a trying ordeal that all Merrington's former doubts of her revived.

"I'd give something to remember where I've seen that infernal woman before," he ejaculated, slapping his thigh emphatically.

"What infernal woman?" asked Captain Stanhill, who had come to the conclusion that he did not like Superintendent Merrington or his style of conversation.

"Why, that woman who has just left the room—that housekeeper. I've seen her before somewhere, in very different circumstances, but I cannot recall where. I recollect her face distinctly—particularly her eyes. I flatter myself I never forget a pair of eyes. Confound it, where the devil have I seen her?"

Captain Stanhill turned away indifferently, and the conversation was terminated by the appearance of Detective Caldew, who appeared in the doorway as Mrs. Rath left the room.

"Dr. Holmes is waiting in the drawing-room if you wish to see him," he announced.

"Bring him here," commanded Merrington curtly. He had a great notion of his self-importance, and had no intention of dancing attendance on a mere country practitioner.

Caldew went away, and shortly reappeared with a little man whom he introduced as Dr. Holmes. The doctor was a meagre shrimp of humanity, with a peevish expression on his withered little face, as though he were bored with his own nonentity. He was dressed in faded clothes and carried a small black bag in one hand and a worn hat in the other. If he had any idea of airing a professional protest at being compelled to wait upon the police, the thought vanished as his eye took in the stupendous stature of Superintendent Merrington, who towered above him like a mastiff standing over a toy terrier.

"Sit down, doctor," he curtly commanded. "I want to ask you a few questions about the death of Mrs. Heredith. You examined the body, I understand?"

Dr. Holmes bowed, put on a pair of gold-rimmed spectacles in order to see Superintendent Merrington better, and waited to be questioned.

"I understand you were summoned to the moat-house last night, doctor, after Mrs. Heredith was murdered, and examined the body. What was the cause of death?"

"The cause of death was a bullet wound," pronounced the doctor oracularly.

"I am aware of that much," answered Merrington irritably. "But a bullet wound is not necessarily fatal. Mrs. Heredith lived some time after her death, so it is certain that the bullet which killed her did not penetrate the heart. What is the nature of the injuries it inflicted?"

"Death in Mrs. Heredith's case was the result of a bullet passing through the left lung. It passed between the second and third ribs in entering the body, traversed the lung, causing a great flow of blood, which filled the air passages."

"Then the cause of death was hæmorrhage?"

"Yes. There was very severe internal hæmorrhage. The face and the left-hand side of the neck were covered with blood. There had also been bleeding from the mouth and nose. Mr. Musard, who accompanied me to the room, told me he had washed it away while Mrs. Heredith was dying, in an endeavour to staunch the flow."

"She was quite dead when you saw her?"

"Oh, yes. Judging by the warmth of the body, and by the fact that blood had ceased to flow, I should say that death had taken place about forty minutes before."

"What time did you reach the moat-house?"

"It would be about twenty minutes past eight. Sergeant Lumbe called at my house at ten minutes past the hour—I made a note of the time—and I went immediately. It is about ten minutes' walk to the moat-house from the village."

"Was the main blood vessel of the lung broken?" asked Captain Stanhill, who had been following the doctor's remarks with close attention.

"The aorta? It is difficult to say from an external examination. Mr. Musard tells me that Mrs. Heredith died about five minutes after he reached the room. The aorta is a very large vessel, and if it were burst bleeding to death would be very rapid."

"Could the wound have been self-inflicted?" asked Merrington.

Dr. Holmes pursed his lips.

"I can form no definite opinion on that point," he said. "By the direction of the bullet, I should say not."

"Have you found the bullet?"

"No, it is in the body. As apparently it took a course towards the right after entering the body, and there is no corresponding wound in the back, I should say that it is lodged somewhere in the vertical column. Of course, I cannot be sure."

"The Government pathologist will clear up these points when he makes the post-mortem examination," said Merrington. "I do not think we have any more questions to ask you, doctor."

"How is your patient, the young husband?" asked Captain Stanhill, as Dr. Holmes rose.

"The symptoms point to brain fever. The family, on my advice, have sent to London for Sir Ralph Horton, the eminent brain doctor."

"I do not wonder his mind has given way under the shock," remarked Captain Stanhill. "To lose his wife in such terrible circumstances after three months' marriage must have been a cruel blow."

"It was the worse in his case because he has always been nervous and highly strung from childhood—partly, I think, as the result of his infirmity. He has a deformed foot. His present illness seems to be a complete overthrow of the nervous system. I have been with him the greater part of the night. He has been highly delirious, but he is a little quieter now."

Merrington pricked up his ears at this last remark. After his fruitless investigations of the morning he was inclined to think that the clue to the murder lay in the past—it might be in some former folly or secret intrigue of the young wife's single days. The question was, in that case, whether the husband was likely to have any knowledge of his wife's secret. If he had, he might, in his delirium, babble something which would provide a clue to trace the murderer. It was a poor chance, but the poorest chance was worth trying in such a baffling case.

"I should like to have a look at your patient," he said to Dr. Holmes.

"It would be impossible to question him in his present state," replied the doctor stiffly.

"I do not wish to question him. I merely wish to look at him."

"In that case you may see him. He is quite unconscious, and recognizes nobody. I will take you to his room, if you wish."

The little doctor bustled along the corridor, and turned into a passage traversing the right wing of the moat-house. About half way down it he paused before a door, which he opened softly, and motioned to the other two to enter.

It was a single bedroom, panelled in oak, which was dark with age, with one small window; but it had the advantage of being as far away as possible from the upstairs bedroom in the left wing where Phil's wife lay murdered. A small fire burnt in the grate, a china bowl of autumn flowers bloomed on a table near the bedside, and a capable looking nurse was preparing a draught by the window. She glanced at the three men as they entered, but went on with her occupation.

The sick man lay on his back, breathing heavily. His black hair framed a face which was ghastly in its whiteness, and his upturned eyes, barely visible beneath the half-closed lids, seemed fixed and motionless.

"Any change, nurse?" the doctor asked.

"No change, sir."

But even as she spoke Phil's face changed in a manner which was wonderful in its suddenness. His features became contorted, as though a sword had been thrust through his vitals, and he struggled upright in his bed, with one shaking hand outstretched. His eyes, glaring with delirium, roved restlessly over the faces of the men at the foot of the bed.

"She's dead, I tell you! Violet's dead.... Have they found him? Ah, who's that?"

Once again he uttered his young wife's name, and fell back on the pillow, motionless as before, but with one arm athwart his face, as though to cover his eyes.

"I shall be glad if you will leave the room," said the little doctor gravely. "Your presence excites him." He hurried round to the bedside and bent over his patient.

CHAPTER IX

"Have you formed any theory of the murder yet?"

It was the evening of the same day, and Superintendent Merrington and Captain Stanhill were once more in the moat-house library. It was Captain Stanhill who asked the question, as he stood warming his little legs in front of a crackling fire of oak logs which had just been lighted in the gloomy depths of the big fireplace. Although it was early in autumn, the evening air was chill.

Superintendent Merrington was walking up and down the room with rapid strides, occasionally glancing with some impatience at the clock which ticked with cheerful indifference on the mantelpiece. He was about to return to London, but was waiting for the return of Detective Caldew and Sergeant Lumbe. Caldew had cycled to Chidelham to see the Weynes, and Lumbe had been sent to investigate a telephoned report of a suspicious stranger seen at a hamlet called Tibblestone, some miles away.

Merrington's face wore a gloomy and dissatisfied expression. He had spent the afternoon in a whirlwind of energy in which he had done many things. He had explored the moat-house from top to bottom, squeezing his vast bulk into every obscure corner of the rambling old place. He had rowed round the moat in a small boat, scrutinizing the outside wall for footmarks. He had mustered the male servants, and superintended an organized beat of the grounds, the woods, and the neighbouring heights. He had interviewed the village station-master to ascertain if any stranger had arrived at Heredith the previous day, and had made similar inquiries by telephone at the adjoining stations. He had inspected the horses and vehicles at the village inn to see if they showed marks of recent usage, and he had peremptorily interrogated everybody he came across to find out whether any one unknown in the district had been seen skulking about the neighbourhood.

Merrington lacked the subtle and penetrative brain of a really great detective, but he possessed energy, initiative, and observation. These qualities had stood him in good stead before, but in this case they had brought nothing to light. The mystery and meaning of the terrible murder of the previous night were no nearer solution than when he had arrived to take up the case, ten hours before.

The most baffling aspect of the crime to him was the apparent lack of motive and the absence of any clue. In most murders there are generally some presumptive clues to guide those called upon to investigate the crime—such things as finger-prints or footprints, a previous threat or admission, an overheard conversation, a chance word, or a compromising letter. Such clues may not prove much in themselves, but they serve as finger-posts. Even the time, which in some cases of murder offers a valuable help to solution, in this case tended to shield the murderer. It seemed as though the murderer had chosen an unusual time and unusual conditions to shield his identity more thoroughly and make discovery impossible.

The case was full of sinister possibilities and perplexities. It bore the stamp of deep premeditation and calculated skill. As the crime was apparently motiveless, it was certain that the motive was deep and carefully hidden. The only definite conclusion that Merrington had reached was that the murderer would have to be sought further afield, probably in London, where the dead girl had lived all her life. There seemed not the slightest reason to suspect anybody in the neighbourhood, as she was a stranger to the district, and knew nobody in it except Mrs. Weyne, who lived some miles away. It was unfortunate that her husband, who was the only person able to give any information about her earlier life, was too ill to be questioned.

On hearing Captain Stanhill's question, Merrington paused abruptly in his impatient pacing of the carpet, and glanced at him covertly from his deep-set little eyes. If he had consulted his own feelings he would have told the Chief Constable that it was not the time to air theories about the crime. But in his present position it behoved him to walk warily and not make an enemy of his colleague. If there was to be an outburst of public indignation because the murderer in this case had not been immediately discovered and brought to justice, it would be just as well if the county police shared the burden of responsibility. Merrington realized that he could best make Captain Stanhill feel his responsibility by taking him fully into his confidence. He was aware that he had practically ignored the Chief Constable in the course of the day's investigations, and it was desirable to remove any feeling that treatment may have caused. Superintendent Merrington had the greatest contempt for the county police, but there were times when it was judicious to dissemble that feeling. The present moment was one of them.

Captain Stanhill, on his part, cherished no animosity against his companion for his cavalier treatment of him. He realized his own inexperience in crime detection, and had been quite willing that Superintendent Merrington should take the lead in the investigations, which he had assisted to the best of his ability. He thought Merrington rather an unpleasant type, but he was overawed by his great reputation as a detective, and impressed by his energy and massive self-confidence. The Chief Constable had not asserted his own official position, because he was aware that he was unable to give competent help in such a baffling case. He was, above all things, anxious that the murderer of Violet Heredith should be captured and brought to justice as speedily as possible, and he had no thought of his personal dignity so long as that end was achieved.

The abstract ideal of human justice is supposed to be based on the threefold aims of punishment, prevention, and reformation, but the heart of the average man, when confronted by grevious wrong, is swayed by no higher impulse than immediate retribution on the wrongdoer. Captain Stanhill was an average man, and his feelings, harrowed by the spectacle of the bleeding corpse of the young wife, and the pitiful condition to which her murder had reduced her young husband, clamoured for retribution, swift, complete, and implacable, on the being who had committed this horrible crime. And he hoped that the famous detective would be able to assure him that his desire was likely to have a speedy attainment. That was why he asked Merrington whether he had formed any theory about the crime.

"It would be too much to say that I have formed a theory," replied Merrington, in response to Captain Stanhill's question. "It is necessary to have clues for the formation of a theory, and in this case we are faced with a complete absence of clues."

"Do you not think that the trinket found by Detective Caldew in Mrs. Heredith's bedroom has some bearing on the murder?" said Captain Stanhill.

"I attach no importance to it. There were a number of persons in the bedroom after the murder was committed, and any of them might have dropped the ornament. Or it may have been lost there days before by a servant, and escaped notice."

"But it was picked up again during Caldew's absence from the room. Do you not regard that as suspicious? Detective Caldew, when he was relating the incident to us this morning, seemed to think that the trinket belonged to the murderer, who took the risk of returning to the room to recover it for fear it might form a clue leading to discovery."

"Caldew reads too much into his discovery," replied Merrington, with an indulgent smile. "Like all young detectives, he is inclined to attach undue importance to small points. As I told him, I cannot imagine a murderer taking such a desperate risk as to return to the spot where he had killed his victim, in order to search for a trinket he had dropped. Caldew may have concealed the brooch so effectually in the thick folds of the velvet carpet that he could not find it again when he looked for it on his return to the room. That explanation strikes me as probable as his own theory of a mysterious midnight intruder returning to search for it while he was out of the room. The trinket may have some connection with the crime, or it may not, but as I have not seen it I prefer to leave it out of my calculation altogether. This case is going to be difficult enough to solve without chasing chimeras. But to return to your question. Although I have not actually formed a theory, my preliminary investigations of the circumstances have led me to arrive at certain conclusions and to exclude possibilities I was at first inclined to adopt. I will go over the case in detail, and then you will see for yourself the conclusions I have formed, and understand how I have arrived at them.

"In the first place, the greatest problem of this murder is the apparent lack of motive. There seems to be no reason why this young lady should have been killed. She had only recently been married, and, apparently, married happily, to a wealthy young man of good family, who was very much in love with her. It is obvious that money difficulties have nothing to do with the crime. Her husband is the only son of a wealthy father, and he is able to give his wife everything that a woman needs for her happiness and comfort. She is cherished, petted, and loved, and has a beautiful home. Who, therefore, had an object in putting an end to this young woman's life in her own home, in circumstances and conditions attended with the utmost possibility of discovery and capture? The perpetrator of the deed must have acted from some very strong motive or impulse to venture into a country-house full of people, at a time when everybody was indoors, in order to kill his victim.

"In a seemingly purposeless murder like this, a certain amount of suspicion gathers round the other members of the household. Human nature being what it is, one should never take anything for granted, but should always be on the watch for hidden motives. But in this case the members of the household, with the exception of Miss Heredith, were downstairs in the dining-room at the time the murder was committed. Miss Heredith left the room a few minutes before the shot was heard. You will recall that she volunteered that statement to us this morning. It occurred to me at the time that that may have been bluff to put us off the scent. Clever criminals often do that kind of thing. My suspicions against her were strengthened by the additional fact that Miss Heredith did not like her nephew's wife. She masked the fact beneath a well-bred semblance of grief and horror, but it was plain as a pikestaff to me. But, after thinking over all the circumstances, I came to the conclusion that she had nothing whatever to do with it."

"Such a possibility is inconceivable," exclaimed Captain Stanhill. "A lady like Miss Heredith would never commit murder."

"It was not for that reason that I excluded her from suspicion," replied Merrington drily. "The points against her were really very damaging. She was out of the dining-room when the scream was heard, and when the others rushed out of the dining-room on hearing the shot, the first thing they saw was Miss Heredith descending the staircase of the wing in which her nephew's wife had been murdered. Fortunately for Miss Heredith, she was almost at the bottom of the staircase when she was seen. The guests streamed out of the dining-room directly the shot was heard, therefore it is impossible that Miss Heredith could have shot Violet Heredith and then reached the bottom of the stairs so quickly. She is able to establish an alibi of time, by, perhaps, half a minute.

"As all the members of the house party were in the dining-room at the time, it is clear that they had nothing to do with the actual commission of the crime. The next thing is the servants, and they also can be excluded from suspicion. When we examined them this morning they were all able to prove, more or less conclusively, that they were engaged in their various duties at the time the murder was committed. The point is that not one of them was upstairs in the left wing of the house when Mrs. Heredith was shot.

"My original impression that the murder was not committed by a native of the district has been deepened by our afternoon's investigations. Where, then, are we to look for the murderer? To answer that question, in part, let us first consider how the murder was committed, and try and reconstruct the circumstances in which the murderer must have entered and left the house.

"Caldew thinks that the murderer entered the house by scaling the bedroom window, and made his exit by the same means. He bases that view on Miss Heredith's belief that the window was closed when she was in the bedroom before dinner. After the murder was committed the window was found open. But Miss Heredith's statement about the closed window does not amount to very much. She does not actually know whether the window was open or shut, because the window curtains were completely drawn at the time she was in the room. Those curtains are so thick and heavy that they would keep out the air whether the window was open or shut, and account for the stuffy atmosphere in a room which had been occupied all day.

"I do not regard the open window as a clue one way or the other. The one thing we must not lose sight of is that nobody can say definitely when it was opened. It may have been opened by Mrs. Heredith herself before Miss Heredith came into the room, or the murderer may have flung it open and escaped from the room that way after committing the murder. Personally, I do not think that he did, but I am not prepared altogether to exclude the possibility of his having done so. But I am convinced that he did not enter the bedroom by scaling the outside wall and getting in through the window. In the first place, there are no marks of any kind on the window sill or the window catch. There is not very much one way or another in the absence of marks on the sill or even on the catch, supposing the window was locked. The murderer might have opened the catch from outside without leaving a mark—I have known the trick to be done—and he might have got into the room without leaving any marks on the sill, particularly if he wore rubber boots. But, what is far more important, there are no marks on the wall outside, or any disturbance or displacement of the Virginia creeper which covers a portion of the wall, to suggest that the murderer climbed up to the room that way. I think it is certain that if he had done so he would have left his marks on the one or the other. The wall is of a soft old brickwork which would scratch and show marks plainly, and the Virginia creeper would break away. In any case, as I said this morning, it would barely sustain the weight of a boy, or a very slight girl. Finally, there are no marks of footsteps approaching the wall in the garden outside.

"The question of entry is naturally of great importance, and that was why I questioned the butler this morning whether the blinds were drawn in the dining-room last night. At that time, before I had had an opportunity of making my subsequent investigations, I deemed it possible that the murderer might have entered from outside by the window. In that case he would have had to pass the dining-room windows to reach the bedroom window, and might have been seen by one of the guests in the dining-room. It would be dark at the time, but last night was a very clear one, and his form might have been discerned flitting past the dining-room windows. But the absence of footprints in the gravel, and more particularly, in the soft yielding earth beneath the bedroom window, is conclusive proof to me that he did not get into the room that way.

"Did he escape by the window? That question is more difficult to answer. It is quite possible that it might have been done without injury, but it is a desperate feat to leap from an upstairs window in the dark. The murderer was in desperate straits, and for that reason we must not rule out the possibility that he did so. But if the leap was made through the window, my argument about the absence of footprints in the soft garden soil underneath the window comes in with additional force. A person leaping from such a height, even in stocking feet or rubber boots, would be certain to leave the impress of the drop, in footmarks or heelmarks, in the soil where he landed.

"Caldew's principal reason for believing that the murderer escaped by the window was based on the point that there was no other avenue of escape possible. We can only speculate as to what happened in the bedroom immediately before the murder was committed, but Caldew's theory is that Mrs. Heredith saw the murderer approaching her, and screamed for help. That scream hurried the murderer's movements. The scream was sure to arouse the household, and it left the murderer with the smallest possible margin of time in which to shoot Mrs. Heredith and make escape by the window. An attempt to escape down the front staircase meant running into the arms of the inmates of the dining-room rushing upstairs. The only other exit from that wing of the house was the disused back staircase, and that was found locked when it was searched after the murder. Therefore, according to Caldew, the murderer escaped by the window because there was no other way out.

"That theory is plausible enough on the surface, but only on the surface. For the same reason that establishes Miss Heredith's innocence, the murderer could not have escaped by running down the staircase, because there was not sufficient time to get past the people who had been alarmed by the scream. But if the murderer was a man, it is just possible that he might have darted out of the bedroom and dropped over the balusters, before the dining-room door was opened, getting clear away without being seen by anybody—not even by Miss Heredith. An examination of the staircase of the left wing has convinced me that this feat was possible. The staircase has a very sharp turn in the middle, which has the effect of hiding the top of the staircase from the bottom, and the bottom from the top. The leap is not so dangerous as the one from the window, because it is not so high. It is probably six feet less, allowing for the flooring beneath and the higher window opening above. The spot by the foot of the staircase where the murderer might have dropped is well screened, even from the view of anybody near the bottom of the staircase, by some tall tree shrubs in tubs, and some armour.

"But there is another and likelier way by which the murderer might have escaped. I saw the possibility of it as soon as I examined the upstairs portion of the wing in which the murder had been committed. There are several places where the murderer could have hidden until chance afforded the opportunity of escape. He would avoid seeking shelter in any of the adjoining bedrooms, because he would realize that they would be searched immediately the murder was discovered, but there are excellent temporary places of concealment behind the tapestry hangings, or in the thick folds of the heavy velvet curtains at the entrance to the corridor, or in the small press or wardrobe which is built right over the head of the stairs. Suppose that the murderer, after firing the shot, dashed out into the corridor with the idea of escaping down the stairs. He hears the guests coming upstairs, and realizes that he is too late. He instinctively looks round for some place to hide, sees the curtains, and slips behind them. From their folds he watches the guests troop along the corridor to the murdered woman's bedroom. He could touch them as they passed, but they cannot see him. Then, while they are all congregated round the doorway of Mrs. Heredith's bedroom, he emerges on the other side of the curtains, slips down the staircase, and gets out of the house without meeting anybody."

"But all the guests did not go upstairs," observed Captain Stanhill, who was following his companion's remarks with close attention. "Some stayed in the dining-room. Tufnell, the butler, made that quite clear when you were examining him this morning."

"Yes—a few hysterical females cowering and whimpering with fear as far away from the door as possible," retorted Merrington contemptuously. "The butler made that clear also."

"But the servants would also have heard the scream and the shot," pursued Captain Stanhill earnestly. "Is it not likely that some of them would have been clustered near the foot of the staircase, wondering what had happened?"

"No," replied Merrington. "Servants are even more cowardly than they are curious. They would be too frightened to congregate at the foot of the staircase, for fear the murderer might come leaping downstairs and discharge another shot in their midst. It is possible, however, that the murderer remained hidden upstairs for some time longer—perhaps until the butler left the house to go to the village for the police, and Musard took all the male guests downstairs to make another search of the house. He would then have an exceedingly favourable opportunity of slipping away unobserved. It is true that the upstairs portion of the wing was searched before that time arrived, but the search was conducted by amateurs who knew nothing about such a task, and would probably overlook such hiding-places as I have indicated."

It appeared to Captain Stanhill that Superintendent Merrington, instead of always adopting his theory of fitting the crime to the circumstances, was sometimes in danger of reversing the process.

"From what you say it seems to me that it is very difficult to tell how the murderer escaped," he remarked.

"It is even more difficult to say how the murderer, after entering the moat-house, found his way to Mrs. Heredith's bedroom in order to murder her. The house is a big rambling place, consisting of a main building and two wings. It would be impossible for you or me or any other stranger to find our way about it without previous knowledge of the place, unless we had a plan. How, then, did the murderer accomplish it? How did he know that Mrs. Heredith slept in the left wing? How did he know that he would find her alone in that wing while everybody else was downstairs at the dinner-table?"

Again, it seemed to Captain Stanhill that Merrington's detective methods had a tendency to multiply difficulties rather than clear them up.

"Perhaps he was provided with a plan of the house," he suggested.

"That answers only one of my points. In my consideration of this aspect of the case, two possible solutions occurred to me. It is impossible for any of the guests to have committed the crime, because they were all downstairs at the time, but it is just possible one of them may have instigated it."

"It is incredible to me that a guest staying in a gentleman's house could plot such a crime," said Captain Stanhill.

"Nothing is incredible in crime," replied Merrington. "I've no illusions about human nature. It is capable of much worse things than that. Strange things can happen in a big country-house like this, filled with a large party of young people of both sexes—flirtations, intrigues, and worse still."

"But not murder, as a general rule," commented Captain Stanhill, with a trace of sarcasm in his mild tones.

"You cannot lay down general rules about murder. An unbalanced human being, under the influence of hatred, jealousy, or revenge, is no more amenable to the rules of society than a tiger. But I do not think that this crime was instigated by one of the guests, because in that case it would probably have been arranged to be committed later in the evening, when the members of the house-party were at the house of the Weynes, and the moat-house was occupied only by the servants. Still, I do not intend to lose sight of the hypothesis. Another possibility is that one of the servants was in league with the murderer. A third possibility is that Mrs. Heredith may have brought in the murderer herself."

"What do you mean?"

"She may have had a lover, and the lover may have murdered her."

"Oh, impossible!" Captain Stanhill repelled the idea with an instinctive gesture of disgust. "It is too monstrous to suppose that a happily married young wife would be carrying on an intrigue three months after her marriage."

"More monstrous things happen every day—human nature being what it is," retorted Merrington coolly. "You must remember that we know practically nothing about her. The people who knew her in London left the house before they could be questioned; Miss Heredith and her brother have no knowledge of her past; and her husband is too ill to tell us anything. Her marriage was apparently a hasty love match—a love match so far as young Heredith was concerned. So far, we have only two slender facts to guide us in our estimate of her, which are contained in the two letters in which young Heredith announced his marriage to his people. According to those statements, she was an orphan who was earning her living as a war clerk in the Government department in which young Heredith held his appointment. That does not carry us very far. During her brief life at the moat-house she seems to have been reticent about her earlier life. Miss Heredith is not the type of woman to have questioned her, and, apparently, she vouchsafed no information. An examination of her boxes and her writing-table has brought to light nothing in the way of writing or correspondence to help us. Such a girl—a bachelor girl in London in war-time—may have had passages in her past life of which her husband knew nothing—passages which may have an important bearing on her murder. Not until we have a thorough knowledge of her antecedents and her past life can we hope to pierce the hidden motives which have led to this murder. It is there, in my opinion, that we must seek for the clue to this strange murder, and it is to that effort I shall devote my energies as soon as I return to London. Until those facts are brought to light we are merely groping in the dark."

CHAPTER X

In accordance with Merrington's instructions, Caldew devoted a considerable portion of the morning seeking information among the moat-house guests. But few of them showed any inclination to talk about the murder. Many of the women were too upset to be seen, and the men had plainly no desire to be mixed up in such a terrible affair by giving interviews to detectives. Everybody was anxious to get away as speedily as possible, and Caldew was compelled to pursue his inquiries amongst groups of hurrying people, flustered servants, and village conveyances laden with luggage. Most of the departing guests replied to his questions as briefly as possible, and gave their London addresses with obvious reluctance; the few who were willing to aid the cause of justice could throw very little light on the London life of the murdered girl. Even those who had been acquainted with her before her marriage seemed to know very little about her.

Caldew finished his inquiries by midday. By that time most of the guests had departed from the moat-house and were on their way to London. Superintendent Merrington and Captain Stanhill were in the library examining the servants. Sergeant Lumbe had gone by train to Tibblestone to sift the story of the suspicious stranger who had descended on that remote village during the previous night.

It wanted an hour to lunch-time, and Caldew decided to spend the time by making a few investigations on his own account before cycling over to Chidelham in the afternoon to see the Weynes.

Caldew had not been impressed with Merrington's handling of the case. Subordinates rarely are impressed with the qualities of those placed over them in authority. They generally imagine they could do better if they had the same opportunities. Caldew was no exception to that rule. It seemed to him that Merrington lacked finesse, and was out of touch with modern methods of criminal investigation. He had been spoilt by too much success, by too much newspaper flattery, by too many jaunts with Royalty. No man could act as sheep-dog for Royalty and retain skill as a detective. That kind of professional work was fatal for the intelligence. Merrington had a great reputation behind him, and his knowledge of European criminals was probably unequalled, but his methods of investigating the moat-house murder suggested that he was no longer one of the world's greatest detectives, if, indeed, he had ever deserved recognition in their ranks. Caldew recalled that his fame rested chiefly on his wide experience rather than on the more subtle deductive methods of modern criminology. It was said in Scotland Yard that when Merrington was at the height of his reputation, twenty years before, his knowledge of London criminals and their methods was so extensive that he could in most cases identify the criminal by merely looking at his handiwork.

As a modern criminologist, Caldew believed that the less a detective intruded his own personality into his investigations the better for his chances of success. He did not think that the loud officialism of Merrington was likely to solve such a deep, subtle crime as the murder of Violet Heredith, and, consequently, he had the chance for which he had waited so long. It now remained for him to prove that he could do better than Merrington. He had sufficient confidence in his own abilities to welcome the opportunity, but at the same time he believed that he was confronted with a crime which would tax all his resources as a detective to unravel.

Like Merrington, he had been struck by the strangeness of the murder. All the circumstances were unusual, and quite outside his previous experience of big crimes. He had also come to the conclusion that the ease with which the murderer had found his way into the moat-house, and afterwards escaped, pointed to an intimate knowledge of the place.

It would be too much to say that Caldew and Merrington reached different conclusions by the same road. Up to a certain point their independent deductions from the more obvious facts of the case were alike, as was inevitable. In every crime there are circumstances and events which are as finger-posts, pointing the one way to the experienced observer. But their subsequent deductions from the outstanding facts branched widely, perhaps because the younger detective did not read so much into circumstances as Merrington. From the same facts they had reached different theories about the murder. Merrington, by a process of minute and careful deductions which he had placed before the Chief Constable, had convinced himself that the key to the murder and the murderer was to be found in London; Caldew believed that the solution of the mystery lay near the scene of the events, and perhaps in the house where the murder was committed.

Caldew was aware that he could have given no satisfactory reason for holding that belief, apart from the point that the murder had been committed by somebody who knew the moat-house sufficiently well to get in and out of the place without being seen. But that point was open to the explanation that the criminal might have provided himself with a plan of the house. Nevertheless, the impression had entered his mind so strongly that he could not have shaken it off if he had tried. But he did not try. He had sufficient imagination to be aware that intuition, in crime detection, is sometimes worth more than the most elaborate deductions.

For the rest, all his speculations about the crime were affected by the trinket he had found in the bedroom on the night of the murder. But the discovery and subsequent disappearance of that clue, as he believed it to be, had not led him very far as yet. He felt himself in the position of a palæontologist who is called upon to reproduce the structure of an extinct prehistoric animal from a footprint in sandstone. The vanished trinket was a starting-point, and no more. It was a possible hypothesis that the person who had dropped the stone and entered the death-chamber in search of it was the murderer, but so far it was incapable of demonstration or proof. As an isolated fact, it was useless, and brought him no nearer the solution of the mystery. But, on the other hand, it was an undoubted fact, and, for that reason, was dependent upon other facts for its existence. It was his task to find out who had dropped the trinket in the bedroom and subsequently returned for it during his own brief absence downstairs. To establish those essential kindred facts was, he believed, to lay hands on the murderer of Violet Heredith.

Caldew walked thoughtfully from the moat-house down to the village, intent on commencing his own independent investigations into the crime. If the solution of the mystery lay near the scene, as he believed, it was possible that some clue might be picked up among the villagers, to whom the daily doings of the folk in "the big house" were events of the first magnitude, and who might, presumably, be supposed to know anything which was likely to throw light on the obscure motive for the crime. It was for that reason he directed his footsteps towards the fountain head of gossip in an English village—the inn. He flattered himself he would be able to extract more local information from the patrons of the place than any other detective could hope to do. To begin with, he was a Sussex man and a native of the village, and since his return, after so many years' absence, he had spent his evenings at the inn renewing old associations and talking to the companions of his boyhood.

A week's renewed village life had taught him the ways of the place and the war-time drinking customs of the inhabitants. Constrained by recent legislation to compress their convivial intercourse into extremely limited periods, the village tradesmen, and a fair proportion of the surrounding farm labourers and shepherds, had fallen into the habit of assembling at the inn at midday, to discuss the hard times and drink the sour weak "war beer" forced on patriotic Britons as an exigent war measure.

Caldew entered a side door which opened into a small snuggery, divided from the tap-room by a wooden partition. It was here that the regular cronies and select patrons of the establishment sat in comfortable seclusion to discuss the crops, the weather, and market prices in the broad Sussex dialect, which Caldew, from the force of old association, unconsciously fell into again when he was with them.

The room was nearly full, but his appearance threw a marked restraint on the group of assembled countrymen. The conversation, which had obviously been about the murder, ceased instantly as he entered and seated himself on one of the forms placed against the partition. The innkeeper, who was standing behind the bar in his shirt sleeves, nodded uneasily in response to his friendly salutation, but the customers awkwardly avoided his glance by staring stolidly in front of them. Caldew attempted to dispel their reserve with a friendly remark, but no reply was forthcoming. It was obvious that the patrons of the inn wanted neither his conversation nor company. One after another, they finished their beer and walked out of the inn with the slow deliberate movements of the Sussex peasant.

Caldew had not allowed for the change the murder had effected on the village mind. His familiar relations with the inn customers had changed overnight. He was no longer the former village lad, returned to his native village, and welcomed from his old association with the place, but a being invested with the dread powers and majesty of the law, from which no man might deem himself safe.

Caldew walked out of the snuggery and opened a door at the side of the house. It opened into a billiard room—a surprising novelty in an English country inn, and the outcome of a piece of enterprise on the part of the landlord, who had picked up a small table cheap at a sale, and installed it in the clubroom, hoping to profit thereby. Again Caldew was conscious of the same distinct air of constraint immediately he entered. Two or three men who were talking and laughing loudly became as mute as though their vocal organs had been suddenly smitten with paralysis. The village butcher, who was at the billiard table in the act of attempting some complicated stroke, stopped abruptly with his cue in mid air, and gazed at the detective with open mouth and a look of apprehension on his florid face, as though he expected instant accusation and arrest for the moat-house murder.

With an irritated appreciation of his changed status in village eyes, Caldew left the inn and walked home for a meal before setting forth to Chidelham to interview Mrs. Weyne.

There was a strong smell of soap suds in his brother-in-law's house, and a vision of his sister's broad back, in vigorous motion over a steaming wash-tub in the kitchen, indicated that she was in the throes of her weekly wash. She ceased her labours at the sound of footsteps, and turned round.

"Oh, it's you, Tom. Come for a bite to eat? Jest sit you down, and I'll have dinner on the table in no time. I got something good for you. Old Upden, the shepherd, brought me a nice rabbit this mornin', and I've stewed it. It's the last one we'll get, I expect. Upden was telling me he ain't going to snare no more, because the boys steal his snares, which ain't no joke, with copper wire at five shillings a pound."

Caldew took a seat at the table, and watched his sister dish up the dinner. As Sergeant Lumbe's income was not sufficient to permit of all the refinements of civilized life, such as a separate room for dining, the family midday dinner was taken in the kitchen, which was the common living room. Mrs. Lumbe's preparations for the meal were prompt and effective. She carried the tub of clothes outside, opened the window to let out the steam, laid knives and forks and plates on the deal table, then put a liberal portion of stewed rabbit into each plate out of the pot which was steaming on the side of the stove. Dinner was then ready, and brother and sister commenced their meal.

Caldew ate in silence, and his sister glanced at him wistfully at intervals. She had no children of her own, and she had a feeling of admiration for the brother she had mothered as a boy, who had gone to the great city and become a London detective. From her point of view he had achieved great fame and distinction, and she cherished in her workbox some newspaper clippings of crime cases in which his name had been favourably mentioned by friendly reporters. She hoped he would be successful in finding the moat-house murderer. She would have liked to question him about the case, but she stood a little in awe of him and his London ways.

"What's the best way to Chidelham, Kate?" asked Caldew, as he rose from the table. "There used to be a footpath across by Dormer's farm which cut off a couple of miles. Is it still open?"

"It's still open, Tom. Old Dormer tried to get it closed, and went to law about it, but he lost. Be you going across to Chidelham?"

"Yes, I shall ride over on my bicycle this afternoon. Do you know where the Weynes live?"

"The Weynes? Oh, you mean the writing chap that bought Billing's place. Their house stands by itself a mile out of the village, just afore you come to Green Patch Hill."

"Thanks. I know Billing's place very well, but I wasn't aware that he had sold it. I'd better be getting along. It's a good long ride."

"What be you goin' there for, Tom?" asked Mrs. Lumbe, with keen curiosity. "About this case?"

"Yes," replied Caldew shortly.

"Have you found out anything yet, Tom?" pursued his sister earnestly, her curiosity overcoming her awe of her clever brother. "Jem was telling me before he went to Tibblestone that a ter'ble gre'at detective come down from Lunnon this mornin', and was stirrin' up things proper. Jem says he's a detective what travels about with the King, and 'e's got letters to his name because of that. Is he on the tracks of the murderer yet, Tom?"

"No, and he's not likely to, as far as I can see," said her brother a little bitterly.

"Dear, dear, that's a pity, for it's a ter'ble thing, and an awful end for the young lady. Jem came home all of a tremble like last night with the ghastly sight of her corpse and I had to give him a drop of spirits to help him to sleep. We was a talkin' about it in bed, and wond'ring who could 'ave done it. Nobody hereabouts, for I'm sure there's nobody in the village would hurt a fellow creature. Besides, the folk at the big house is too respected for a living soul to think of harming them."

"They are popular with everybody, are they?" said Caldew, sitting down again with the realization that he was likely to gather as much information about the Heredith family from his sister as he could obtain anywhere else.

"Oh, yes," replied his sister. "It's only nat'ral they should be. Sir Philip is a good landlord, and he and Miss Heredith are very generous to folk."

"Is Philip Heredith well-liked in the district?"

"He's been away so long that folk don't know much about him. But I never heard anybody say anything against him. He's different from Sir Philip, but he seems gentle and kind."

"He used to be a quiet and solitary little chap years ago," remarked Caldew. "I remember climbing a tree in Monk's Hill wood for a bird's nest for him. He couldn't climb himself because of his lameness."

"It doesn't seem like a Heredith to be small and lame," said Mrs. Lumbe thoughtfully. "I've heard those who ought to know declare that Miss Heredith never forgave his mother for bringing him into the world with a lame foot. The servants at the big house say Mr. Phil has always been ter'ble sensitive about his lameness. That's what made him so lonely in his ways, though he was rare fond of animals and birds. We was all taken aback when we heard of his marriage. He always seemed so shy of the young ladies. The only girl I ever knowed him to take any notice of was Hazel Rath. I have met them walking through the woods together."

"Who is Hazel Rath?"

"The daughter of the moat-house housekeeper. She came to the moat-house with her mother nearly ten years agone. She was a pretty little thing. Miss Heredith was very fond of her, and sent her to school. Mr. Philip was fond of her too, in his way, though, of course, there could never a'been anything between them. But nobody hereabouts ever expected him to marry a London young lady."

"Why not?" asked Caldew.

"The Herediths have always married in the county, as far back as can be counted. It was thought Miss Heredith would make a match between Mr. Philip and the daughter of Sir Harry Ravenworth, of the Wilcotes. The Ravenworths are the second family in the county, and well-to-do. 'Twould a'been a most suitable match, as folk here agreed. But 'twas not to be, more's the pity."

Caldew nodded absently. His original interest in his sister's talk was relapsing into boredom because it seemed unlikely to lead to anything of the slightest importance about the murder.

"The young lady he did marry was not a real lady, so I've heard say," continued Mrs. Lumbe, placidly pursuing the train of her reflections. "She didn't come much into the village, but when she did she walked about as though she were bettermost, and everybody else dirt beneath her feet. But I have heard that she had to earn her own living in London before Mr. Philip fell in love with her pretty face. If that's the truth, she gave herself enough airs afterwards, and did all she could to make Miss Heredith feel she'd put her nose out of joint, as the saying is."

"What do you mean by that?" asked Caldew sharply, with all his senses again alert.

"Well, you know, Tom, Miss Heredith has been the mistress of the moat-house and the great lady of the county since Lady Heredith died. But when Mr. Philip brought his young wife down from London that was all changed. The young lady soon let her see that she wasn't going to be ruled by her, and didn't care for her or her ways. They do say it was a great trial to Miss Heredith, though she tried not to let anybody know it."

"Where did you learn this?" Caldew asked abruptly.

"Lord, Tom, how short you pick me up! Milly Saker, who's parlourmaid at the moat-house, told me in the strictest confidence, because she knew I wouldn't tell anybody. And I wouldn't tell anybody but you, Tom. She told me from the very first that she didn't think the two ladies would get on together. They were so different, Milly said, and she was certain Miss Heredith didn't think the young lady good enough to marry into the Heredith family."

"Did she tell you if they had ever quarrelled?"

"I asked her that, and she said no. Miss Heredith is always the lady, and she wouldn't lower herself by quarrelling with anybody, least of all with anybody she did not consider as good a lady as herself. But Milly says she was sorely tried at times. Milly thought it would end up in her leaving the moat-house and marrying her old sweetheart, Mr. Musard, who's just returned from his foreign travels. Perhaps you've seen him."

"Yes, I've seen him," said Caldew. "So he is her old sweetheart, is he?"

"So folk used to say," returned Mrs. Lumbe. "I remember there was some talk of a match between them when I was a girl, but nothing came of it. It's my opinion that Miss Heredith must have refused him then because of his wild days, and he took to his travels to cure his broken heart. But they still think a lot of each other, as is plain for everybody to see, and go out for walks together arm in arm. So perhaps it will all come right in the end."

With this comfortable doctrine of life, based on her perusal of female romances, Mrs. Lumbe got up from her seat to clear the table.

"I trust it will," said her brother, but his remark had nothing to do with the triumph of true love in the last chapter.

He left the room to get his bicycle to ride to Chidelham.

CHAPTER XI

On his way to Chidelham, Caldew again pondered over the murder, and for the first time seriously asked himself whether Miss Heredith could have committed the crime. He had glanced at that possibility before, and had practically dismissed it on the score of lack of motive, but his sister's story of the differences between Miss Heredith and her nephew's wife supplied that deficiency in a startling degree. In reviewing the whole of the circumstances by the light of the information his sister had given him, it now seemed to him that Miss Heredith fitted into the crime in a remarkable way.

The most important fact leading to that inference was that she alone, of all the inmates of the moat-house the previous night, was out of the dining-room when the murder was committed. That supposition took no cognizance of the servants, but Caldew had all along eliminated the servants in his consideration of the crime. In the next place, it supplied an explanation for the disappearance of the bar brooch from the bedroom. In all likelihood the butler had first acquainted his mistress with his discovery of the unlocked staircase door, and she, realizing where she had dropped her brooch, had seized upon the opportunity to request Musard to call the detective downstairs and tell him about the door. In his absence she returned to the bedroom for the brooch.

This theory seemed plausible enough at first blush, but as Caldew examined it closely several objections arose in his mind. The hidden motive of the crime, as innocently laid bare by his sister, was strong, but was it strong enough to impel a woman like Miss Heredith, with the rigid principles of her birth, breeding, and caste, and a woman, moreover, who had spent her life in good works, to commit such an atrocious murder? Caldew considered this point long and thoughtfully. With his keener imagination he differed from Merrington by relying to some extent on external impressions, and he could not shake off his first impression of Miss Heredith as a woman of exceptionally good type. He had to admit to himself that her graciousness and dignity were not the qualities usually associated with a murderer. Religion, hypocrisy, smugness, plausibility; these were the commonest counterfeit qualities of criminals; not dignity, worth, and pride.

There was, of course, the possibility that Miss Heredith, grown imperious with her long unquestioned sway at the moat-house, had quarrelled with the young wife, and committed the murder in a sudden gust of passion. The most unlikely murders had been committed under the sway of impulse. Caldew recalled that Miss Heredith had been the last person to see the murdered woman alive, and nobody except herself knew what had occurred at that interview. It might be that the young wife had said something to her which rankled so deeply that she conceived the idea of murdering her.

Caldew, on reaching this stage of his reasoning, shook his head doubtfully. He had to admit to himself that such a theory did not ring true. If Miss Heredith had been maddened by some insult at the afternoon's interview, she was far more likely to have killed Mrs. Heredith immediately than have waited until dinner-time. And, if she had committed the murder, why had she gone about it in the manner likeliest to lead to discovery, openly leaving her guests a few minutes before, and allowing herself to be seen afterwards descending the staircase? Even the veriest neophyte in crime usually displayed some of the caution of self-preservation.

But Caldew was too experienced in criminal investigation to reject a theory merely because it was contrary to experience. There existed presumptions for suspicion of Miss Heredith which at least warranted further inquiry. And, thinking over these presumptions, he arrived at the additional conclusion that the theory of her guilt could also be made to account for the puzzle of the open window in Mrs. Heredith's bedroom. Caldew believed that the open window had some bearing on the crime. His first impression had been that the murderer had entered and escaped by that means. The Virginia creeper to which Weyling had directed attention that morning had strengthened that belief, in spite of Merrington's opinion that the plant would not bear a man's weight. But now it seemed to him that Miss Heredith might have opened the window for the purpose of throwing the revolver into the moat so that it should not be found. He determined to investigate that possibility as soon as he returned to the moat-house.

He reached his destination only to learn that Mr. and Mrs. Weyne had motored over to the moat-house to pay their condolences to the family. He remounted his bicycle and rode back as fast as he could, chagrined to think that he had wasted the best part of an afternoon in a fruitless errand.

It was evening when he reached Heredith again, and rode through the woods towards the moat-house. It looked deserted in the gathering twilight. A fugitive gleam of departing sunshine fell on the bronze and blood-red chrysanthemums in the circular beds, but the shadows were lengthening across the lawn, and the mist from the green waters of the moat was creeping up the stained red walls.

His ring at the front door was answered by the pretty parlourmaid who had been dusting the hall before breakfast. He recognized in Milly Saker a village playmate of nearly twenty years ago, and he recalled that it was she who had told his sister of the difference which had existed between Miss Heredith and her nephew's wife.

Milly greeted the detective with a coquettish smile of recognition.

"How are you?" she said. "You wouldn't look at me this morning. You seemed as if you didn't want to recognize old friends."

Caldew's mind was too preoccupied to meet these rural pleasantries in the same spirit.

"Is Miss Heredith in?" he asked, stepping into the hall.

"I shouldn't be here talking to you if she was," replied the girl pertly. "She's gone to the village in the motorcar to meet Mr. Musard. She's just got a telegram to say he's coming back."

"I thought he was going to France," said Caldew.

"Well, he's not. The telegram says he's not. So Miss Heredith's gone to meet him by the evening train. Tufnell's out too. I don't know where he's poked to, but I shan't cry my eyes out if he never comes back."

"Have Mr. and Mrs. Weyne been here?"

"Yes. They drove over in their car, and saw Miss Heredith and Sir Philip. They weren't here very long."

"Where are Superintendent Merrington and Captain Stanhill?"

"In the library. They come in about an hour ago. The big gentleman has to go back to London to-night—I heard him say so. A good riddance too. He had all the servants in the library this morning, bullying them dreadfully."

"What did he say to you?" asked Caldew, with a smile.

"Nothing," responded the girl promptly, "except what he said early this morning, when he stopped me in the hall here, and put his great ugly hand under my chin, and told me he'd have a talk with me by-and-by. But he didn't get the chance, because I was over in the village all the morning with my mother, who's been ill. But he gave all the other girls such a time that they haven't done talking of it yet. Gwennie Harden, who sleeps with me, says he must have thought one of us murdered Mrs. Heredith, and the cook was so angry with the questions he asked her that she was going to give a month's warning on the spot, but old Tufnell talked her over, saying that it was only done in the way of duty, no personal reflection being intended. Tufnell begged her pardon for what she'd had to put up with, and the cook granted it, and there the matter ended. But they do say that Mrs. Rath—that's the housekeeper—came out of the library looking fit to drop. But Hazel Rath didn't go into the library, although she stayed here last night, and has been with her mother all day. Favouritism, I call it. Why should they put all us servants through our facings, and leave her alone?"

The mention of Hazel Rath's name recalled to Caldew's mind the information his sister had given him about the early association between her and Philip Heredith. But the import of that statement, and the significance of the piece of news Milly Saker had just given him, were not made clear to him until later. At the moment his thoughts were fixed on the idea of testing his new theory about the open window while Miss Heredith was absent. As he turned away, he asked the girl where Sir Philip was.

"He's sitting with Mr. Phil," was the reply.

"I suppose there is nobody upstairs in the left wing?" he added.

"Nobody but the corpse," responded Milly, with a slight shiver. "Miss Heredith's had her bedroom shifted. Last night she slept downstairs, but this morning she gave orders for the white bedroom in the right wing to be prepared for her. I reckon she wants to get as far away from it as possible, and I don't blame her."

Caldew proceeded upstairs, and entered the death-chamber in the silent wing. On his way back from Chidelham he had picked up a round stone, which he now took from his pocket, intending to throw it from the window, and mark the spot where it fell into the moat. He opened the window, and looked out across the garden. The distance to the moat was much farther than he had imagined; so great, indeed, that his own shot at the water fell short by several feet. It was impossible that Miss Heredith could have accomplished such a remarkable feat as to hurl a revolver across the intervening space between the window and the moat. No woman could throw so far and so straight.

This unforeseen obstacle rather disconcerted Caldew at first, but on looking out of the window again it seemed to him, by the lay of the house, that the window of Miss Heredith's bedroom was closer to the moat than the window at which he was standing. As Miss Heredith had transferred her bedroom to the other wing, he decided to go into the room and see if he were right. He still clung to his new idea that the revolver had been thrown into the moat, although his altered view that it might have been thrown from Miss Heredith's window meant the abandonment of his other assumption that the disposal of the revolver by that means accounted for the open window in Mrs. Heredith's bedroom. Caldew realized as he left the room that the question of the open window still remained to be solved. What he did not realize was that he was distorting the facts of the case in order to establish the possibility of his own theory.

The door of the room which Miss Heredith had occupied was ajar. He pushed it open and entered. There was within that deserted and desolate air which a room so quickly takes on when the occupant has vacated it. The heavier furniture and the bed remained to demonstrate the ugliness of utility after the accessories and adjuncts of luxury had been carried away.

The blind was down and the room in partial darkness. Caldew went to the window, raised the blind, and looked out. The distance to the moat was appreciably nearer, compared with the window of the room he had just left, but the distance was still considerable.

As Caldew turned from the window, with the reluctant conviction that he had been nursing an untenable theory, a last ray of sunshine shot through the open window, causing the dust he had raised by his entrance to quiver and gyrate like a host of mad bacilli dancing a jig. The shaft of light, falling athwart the dismantled toilet-table, brought something else into view—a tiny fragment of gold chain dangling from the polished satinwood drawer.

Caldew pulled the drawer open. Inside was a lady's thin gold neck chain, with a bundle of charms and trinkets attached to the end, which had evidently been left behind and forgotten. He glanced at the chain carelessly, and was about to replace it in the drawer, when his eye was arrested by one of the trinkets. It was a small image, not much over an inch in length; a squatting heathen god, with crossed arms and a satyr's face—a wonderful example of savage carving in miniature.

It was not the perfection of the carving or the unusual nature of the ornament which attracted Caldew's attention, but the material, of which it was composed, a clear almost transparent stone, with the faintest possible tinge of green. Holding it in the sunlight, Caldew was able to detect one or two minute black flecks in the stone. There was no doubt about it—the image was of the same peculiar material as the trinket he had seen in the murdered woman's room the previous night.

As he stood there examining the charm, the murmur of voices not far away fell on his ears. Looking cautiously out of the window, he saw Musard and Miss Heredith walk round the side of the house to the garden, deep in earnest conversation. Caldew backed away to an angle where he was not visible from beneath, and watched them closely. Musard was talking, occasionally using an impressive gesture, and Miss Heredith was listening attentively, with a downcast face, and eyes which suggested recent tears. As she passed underneath the window at which he was watching, she raised a handkerchief to her face and sobbed aloud. Caldew wondered to see the proud and reserved mistress of the moat-house show her grief so freely in the presence of Musard, until he remembered what his sister had told him of their supposed early love for each other. And with that thought came another. It must have been Musard, the explorer, the man who had wandered afar in strange lands in search of precious stones, who had brought to the moat-house the peculiar stone of which the missing brooch and the little image had been fashioned.

Acting on the swift impulse to take the image to Miss Heredith and see how she received it, Caldew slipped the chain into his pocket and hurried downstairs. At the bottom of the staircase he was stopped by Tufnell, who had evidently been waiting for him to descend. The usually imperturbable dignity of the butler was for once ruffled, and he looked slightly flushed and dishevelled.

"I have been down to the village looking for you," he said, in a querulous tone. The majesty of the law had not vested Caldew with any dignity in the old butler's eyes. He saw in him only the village urchin of a score of years ago, whose mischievous pranks on the Heredith estate had been a constant source of worry to him.

The detective appreciated the estimation in which the old man held him, and the fact did not tend to lessen his own irritation.

"What did you want me for?" he curtly asked.

"I did not want you, but the gentlemen in the library do. Superintendent Merrington thought you had been a long time away, and he sent me down to the village to look for you. He is anxious to return to London. You will find him in the library."

The butler's cool assumption that it was Merrington's privilege to command, and Caldew's duty to obey, nettled the latter considerably. He felt that Merrington had, in his offensive way, deliberately asserted his official authority in order to humiliate him in his native place. Acting on the impulse of anger he replied:

"I have some things to attend to before I can see him. You can tell him so, if you like."

He walked away towards the hall door, conscious that the butler was standing stationary by the stairs, watching him. When he got outside, he turned his steps towards the garden; but brief as had been the interval since he had seen Musard and Miss Heredith conversing together by the sundial, it had been sufficient to bring the conversation to a conclusion. Miss Heredith was no longer to be seen, and Musard was sauntering along the gravel walk smoking a cigar.

Had they seen him at the window, and broken off their conference in consequence? It looked as if this were so. Miss Heredith must have entered the house by another door, because if she had gone in by the front door he must have encountered her. Caldew would have retraced his steps if Musard had not looked up, and, seeing the detective, waited for him to approach.

Caldew walked towards him, wondering whether Miss Heredith had missed her chain of charms, and had gone upstairs to find it. In that case, he reflected grimly, the position of the previous night was reversed, and this time it was she who was forestalled. It was an ironical situation, truly, but he was to some extent the master of it.

Musard nodded to the detective and proffered his cigarcase. Caldew accepted a cigar and admired the case, which was made of crocodile skin, worked and dressed in a manner altogether new to him. He had never seen anything like it in London tobacconists' shops, and he said so.

"Native manufacture," replied Musard, selecting a fresh cigar. "My Chinese boy shot the crocodile which provided it. It's a rare thing for a Chinese to be a good shot with a modern English rifle, but my boy would carry off anything at Bisley. He never misses. It was lucky for me that he didn't that time, because the brute came along to bag me while I was swimming in a river. Suey, hearing me call, ran out from the tent with my rifle, and shot him from the bank. He got him through the eye—the eye and the throat are the only two vulnerable spots in a crocodile. A bullet will rebound off the head as off a rock."

"Where did this happen?" asked Caldew, in an interested tone. His own knowledge of crocodiles was confined to the fact that he had once seen a small one in a tank at the Zoological Gardens.

"In Zambesi. There are plenty of them there in the rivers and mango swamps. Some hunters stake a dog overnight by the river bank, and the animal gives them warning of the approach of the reptiles by howling with terror. It is rather cruel—to the dog."

"Undoubtedly," said Caldew.

"How are you getting on with your investigations in this case?" continued Musard, abruptly changing the conversation.

Caldew was instantly wary, and stiffened into an attitude of official reserve, wondering why Musard should seek to question him about the murder.

"I am an old friend of the Herediths," continued Musard, as though divining the other's thoughts. "This murder is a very terrible thing for them. I am afraid it may mean Sir Philip's death-blow. He is old and feeble, and the shock, and his son's illness, have had a very bad effect on him. I should have gone to France to-day for the War Office, but I arranged for somebody to go in my place in order to remain with the family in their hour of trial. Have you found out anything which leads you to suppose you are on the track of the murdered?"

"I am afraid I cannot tell you anything about the investigations," replied the detective cautiously. "I am not in charge of the case, you know."

"I understand," rejoined the other, with a nod. "Perhaps I should not have asked you. My anxiety must be my excuse."

He uttered this apology so courteously and pleasantly that Caldew felt momentarily ashamed of his own rigidly official attitude. But his instincts of caution quickly reasserted themselves, and he told himself that in this sinister case it was his business to be on his guard and talk to nobody.

The situation was terminated by the reappearance of Miss Heredith from a door at the side of the house. The detective was a little surprised to see her again, for he had conceived the idea that she had gone indoors to avoid meeting him. She went eagerly to Musard without noticing him.

"Oh, Vincent!" she exclaimed, and the look of relief on her face was unmistakable. "Sir Ralph Horton is just leaving. He says that Phil has passed the crisis, and there is no need for him to stay any longer. Phil still needs great care and attention, but Sir Ralph says it will be quite safe to leave him in Dr. Holmes's hands. There is no fear for his brain, thank God."

"This is good news," said Musard. "Have you told Sir Philip?"

"Not yet. I thought it better to defer it until after dinner. I want you to tell him then."

Miss Heredith turned as though to re-enter the house, but Caldew, who had been hovering a few paces away within earshot of this dialogue, approached her with the gold chain in his hand.

"Excuse me, Miss Heredith," he said. "One of the maids told me that you no longer occupied the room upstairs in the left wing, so I took the liberty of going in there to see if it was possible for the murderer to have escaped by clambering from the window of one room to another, and while I was there I found this chain. It was hanging out of a drawer of the toilet-table near the window, and as it had obviously been forgotten I thought I had better restore it to you."

He held it out to her as he finished speaking, keenly watching her face for some sign of confusion or trepidation. But Miss Heredith received the chain calmly, and thanked him for returning it. Caldew was disappointed at the failure of his test, but he essayed a further shot.

"I noticed a very peculiar little image among the charms on the chain," he said hesitatingly. "I have never seen anything like it before, and I couldn't help wondering where it came from."

It was a clumsy trap, and he realized it, but he was too anxious to achieve his end by more subtle methods. There was nothing in Miss Heredith's calm countenance to suggest that she was alarmed or uneasy at his curiosity. She turned to Musard.

"Mr. Caldew means the strange little image you gave me when you arrived, Vincent. What is it?"

She held out the chain, and the explorer took it in his big brown hand. He separated the image from the other charms with his forefinger, and turned it over carelessly.

"That is a tiki," he said.

The explanation conveyed nothing to Caldew.

"I have never heard the word before," he said. "What is a tiki?"

"It is the Maori word for the creator of man, and is also taken to represent an ancestor," Musard explained. "The Maoris are to some extent ancestor worshippers, and adorn their pahs and temples with large wooden images of immense size, supposed to represent some renowned fighting ancestor. These images are worshipped as gods, and are believed to be visited by the spirits, who ascend to converse with them by the hollow roots of a pohutukawa tree, which descends into the Maori nether regions. The smaller tikis, or, more strictly speaking, hei-tiki, such as this, are carved as representations in miniature of the larger images, and are worn as neck ornaments. They are supposed to render the wearer immune from the wicked designs of evil spirits."

"From what material are they carved?" said Caldew, who had followed this explanation attentively. "I have never seen anything resembling it. It seems as clear and colourless as glass, but it emits a faint greenish lustre, and there are black flecks in it."

"It is nephrite, or Maori greenstone," replied Musard. "London jewellers term it New Zealand jade."

"Surely this stone is not jade?" said Caldew, in some surprise. "I have seen New Zealand jade ornaments in London shops, but they were made from a dull deep greenstone, not a bit like this stone, which is clear as crystal, and has a lustre."

"There are different sorts of jade," replied Musard. "The present craze of Society women is for Chinese pink jade and tourmalin. A good pink jade necklace will readily bring a thousand pounds in Bond Street, and it is going to be the fashionable jewel of the season. New Zealand nephrite has not yet come into popular favour with English ladies, and only the commoner dark green variety, which is frequently spurious, is seen here. This image was made of the rarer kind of pounamu, as the Maoris call it."

"It is very pretty," said Caldew. "Have you any more of it?" He flattered himself that the assumption of carelessness in his tone was not overdone.

"No," replied Musard. "It was the only piece of the rare kind I was ever lucky enough to obtain."

"There was another small piece, Vincent," remarked Miss Heredith. "You brought it about ten years ago. It was the same kind of transparent stone, with black flecks in it."

"I had forgotten. I gave it to Phil, didn't I? What did he do with it?"

"He had it made into a brooch for Hazel Rath, and gave it to her as a birthday gift."

CHAPTER XII

As Caldew returned to the house for his interview with Merrington, the one clear impression on his mind was that the discovery of the owner of the missing brooch was the starting point in the elucidation of the murder.

In the library he found Superintendent Merrington, Captain Stanhill, Inspector Weyling, and Sergeant Lumbe. The sergeant, who looked tired and dirty, was apologetically explaining that his visit to Tibblestone had been fruitless.

"I had my journey for nothing," he was saying in his thick country voice, as Caldew entered. "I had a wild goose chase all over the place, and then it turned out that this chap Mr. Hawkins telephoned about was only a canvasser for In Memoriam cards for fallen soldiers. I come across him at last sitting by the roadside eating his dinner and reading a London picture paper. He looked a doubtful sort of a customer, sure enough, but he was able to prove that he was playing bagatelle in the inn last night at the time the murder was committed."

Superintendent Merrington dismissed this information with a nod, and turned to Caldew.

"Did you interview Mrs. Weyne?" he asked.

"They were not in," was the reply. "I was told they had motored to the moat-house. Did you see them?"

Superintendent Merrington frowned. He had not seen the Weynes, and he had not been informed of their visit. It was another addition to the sum of untoward incidents which had happened to him since his arrival at the moat-house, and he felt very dissatisfied and wrathful.

"I am returning to London by the next train, Caldew," he said, in his authoritative voice. "Official business of importance demands my immediate presence. I will have some inquiries made at Scotland Yard about the people who have been staying here. In the meantime, you had better remain on the spot and continue your inquiries under the Chief Constable."

"I shall be very glad of Detective Caldew's help in unravelling this terrible mystery," Captain Stanhill remarked courteously.

Caldew drew several conclusions from his chief's speech. Merrington was puzzled about the case, but had no intention of taking him into his counsel. Merrington believed that the murderer had got clear away, and, therefore, further local investigation was useless, but he deemed it advisable to keep a Scotland Yard man on the scene to watch for possible developments, because he placed no reliance on the county police. It was apparent that Merrington thought the murderer had come from a distance, and he was going to seek him in London. But he was leaving nothing to chance. He was retaining control of the investigations at both ends in order to monopolize the glory of the capture. If the murderer escaped, Caldew and the county police could be made the scapegoats for public indignation.

But while paying the involuntary tribute of swift anger towards these astute tactics of his departmental chief, Caldew realized with satisfaction that he was in the possession of a piece of valuable information which might upset his calculations.

"There are several people in the district whom it will be advisable to interview," continued Merrington, hastily consulting his notes. "In the first place, you must make another effort to see the Weynes. Mrs. Weyne may be able to give us some valuable information about Mrs. Heredith's earlier life. And I think you should see the station-master of Weydene Junction. The murderer may have walked across country to the junction rather than face the greater risk of subsequent identification by taking the train at one of the village stations on this side of it. And you had better see the housekeeper's daughter and get a statement from her. I do not suppose she knows anything about the crime, but she was here last night, and she had better be seen. She is employed as a milliner at the market town of Stading."

"Do you mean Hazel Rath?" inquired Caldew, in some surprise.

"Yes. She is the daughter of the housekeeper. She stayed here last night with her mother, but left to go back to her employment by the first train this morning."

"There must be some mistake about that. I understand she is still in the house."

"Who told you so?"

"One of the maidservants."

"We had better have the maid in and question her. What is her name?"

"Milly—Milly Saker."

Merrington touched the bell, and told the maidservant who answered it to send in Milly Saker.

The girl came in almost immediately, looking half defiant and half afraid. Merrington glanced at her keenly.

"You're the girl I saw dusting the hall this morning," he said. "Why did you not come in with the other servants to be examined?"

"Because I wasn't here," answered the girl pertly.

"Where were you?"

"Down in the village, at my mother's place."

"Who gave you permission to go?"

"Mrs. Rath, the housekeeper."

"Did you ask her for leave of absence?"

"No. She knew my mother was ill, and she said to me after breakfast, 'Milly, would you like to go and see your mother this morning?' I said, yes, I should, if she could spare me. She told me she could, so I thanked her and went."

Superintendent Merrington and Captain Stanhill exchanged glances. The same thought occurred to both of them. Mrs. Rath, the housekeeper, had assured them that she had sent all the servants to the library to be examined. Merrington turned to the girl again.

"Mrs. Rath's daughter was staying with her last night, wasn't she?"

"Yes."

"Is she still here?"

"Yes."

"Are you quite sure of that?"

"Yes, when I was outside about half an hour ago, I saw her through the window, sitting in her mother's room."

This piece of information conveyed some significance to Merrington's mind which was not apparent to Caldew. He paused for a moment, and then continued abruptly:

"Where were you last night at the time of the murder?"

"Please, sir, I don't know nothing about it," responded the girl with a whimper.

"Control yourself, my good girl," said Captain Stanhill soothingly. "Nobody suggests you had anything to do with it."

For reply, the girl only sobbed loudly. Superintendent Merrington, who had his own methods of soothing frightened females, shook her roughly by the arm.

"Listen to me," he sternly commanded. "Do you want to go to prison?"

"N—o, sir," responded Milly, between a fresh burst of sobs.

"Then you'd better stop that noise and answer my questions, or I'll put you under lock and key till you do. Where were you last night when the murder was committed?"

"I was waiting at table till dessert was served," replied the girl, thoroughly subdued by the overbearing manner of the big man confronting her.

"What did you do when you left the dining-room?"

"I went to the kitchen and was talking to cook for a while."

"And what did you do then?"

"I went up the passage and into the hall to see if dinner was finished. I knew Miss Heredith was anxious to have dinner over early as they were all going out, and I wanted to get dinner cleared away as quickly as I could, because I wanted to go out myself. I saw her leave the room and go towards the front door, but nobody else came out of the dining-room, and I could hear somebody talking. So after waiting a little while, and seeing nobody else come out, I went back towards the kitchen."

"Where were you standing while you were waiting?"

"Just at the corner of the passage leading up from the kitchen."

"You didn't go up stairs at all?"

"No, of course I didn't. 'Tisn't my place to go upstairs."

"Don't be saucy, but answer my questions. Did you hear the scream and the shot?"

"No, I didn't. I was back in the kitchen before then, and the kitchen is right at the back of the house. Cook and me didn't know anything about it till one of the girls came running down and told us about what had happened."

"Did you see anybody except Miss Heredith in the hall or on the staircase of the left wing while you were standing at the end of the passage?"

"Nobody except Miss Rath."

"Do you mean the housekeeper's daughter?"

"Yes."

"When did you see her?"

"As I was standing there waiting for a chance to clear away the dinner things, she come up from the centre passage leading from the housekeeper's rooms, and turned into the hall."

"Where was she going?"

"I don't know. I didn't ask her," replied the girl, who had regained something of her pert assurance.

"Did she see you?"

"No. I was standing at the end of the kitchen passage, which is close to the right wing. The passage she come out of was quite a long way from where I was standing, almost in the centre of the house. She turned the other way."

"She turned to the right, then, as she emerged from the passage, and walked in the direction of the left wing?"

"I don't know where she was going to. All I know is that I saw her turn out of the passage, and walk, as if might be, up the hall in that direction."

"Did you notice her actions?"

"I can't say as I did particular, except that she was walking in the shadow, on the side nearest to the passage she come out of, and seemed to be looking at the dining-room door."

"You are sure it was Hazel Rath?"

"Oh, it was her all right," replied Milly confidently. "I recognized her, as well as the dress she was wearing."

"Was this before or after you saw Miss Heredith leave the dining-room?"

"About ten minutes afterwards."

"Did you mention to anybody that you saw her?"

"I did not," replied the girl, as if the matter were one of supreme indifference to her.

"Why not?"

"I suppose Miss Rath is free to go where she pleases," said the girl airily. "She's privileged. When she used to live here she had the run of the house, just like one of the family. Tain't my business to question her comings and goings."

"Oh, Miss Rath used to live here, did she? How long ago?"

"Till about two years ago, before she went to business."

"And how long did she live here?"

"It must have been a good seven years or more," said Milly, considering. "She come here as a little girl when her mother come as housekeeper. Miss Heredith took a great fancy to her, and she was made quite a pet of the house, and did just what she liked. When she grew up she used to help her mother, and do little things about the house. But she never gave herself airs—I will say that."

"Very well. You may go now."

"Caldew," said Merrington quickly as the door closed behind the girl, "go and find the housekeeper and send her in here. And then keep an eye on her daughter, and do not let her out of your sight, until I send for you. Then bring her in."

When Caldew left the room on his errand, Captain Stanhill turned to Superintendent Merrington with a pained expression on his face.

"Do you suspect—" he commenced.

"I suspect nobody—and everybody," was the prompt reply. "My duty is to find out the facts, and my business is now to ascertain why the housekeeper lied to me about her daughter this morning. She was a fool to try and trick me. There's something underneath all this which I'll sift to the bottom before I leave."

There was a timid tap, and the door opened slowly, revealing the frail black figure of the housekeeper standing hesitatingly on the threshold. Her frightened eyes were directed to Merrington's truculent ones as though impelled by a magnet.

"You—you wished to see me?" she stammered.

"Yes. Come in." Merrington curtly commanded. "Close that door, Lumbe. Sit down, Mrs. Rath, I have a few questions to ask you."

The housekeeper took a seat, with her eyes still fixed on Merrington's face. She looked ill and haggard, but the contour of her worn face, and the outline of her slender figure suggested that she had once possessed beauty and attraction. Merrington, staring at her hard, again had the idea that he had seen her long ago in different conditions and circumstances, but he could not recall where.

"Look here, Mrs. Rath," he commenced abruptly. "I want to know why you lied to me this morning."

"I—I don't know what you mean. I didn't come here to be insulted." The housekeeper uttered these words with a weak attempt at dignity, but her lips went suddenly white.

"Don't put on any fine-lady airs with me, for they won't go down," said Merrington, in a fierce, bullying tone. "You know what I mean very well. You told me this morning, when I asked you, that you had sent in all the servants to be examined. I have just discovered that you did not. There was a girl, Milly Saker, whom I did not see. Why was that?"

It seemed to Captain Stanhill that the tension of the housekeeper's face relaxed, and that a look of relief came into her eyes, as though the question were different from the one she had expected.

"I did not tell you a lie," she replied, in a firmer tone. "I sent in all the servants who were in the house at the time. Milly was not at home."

"Where was she?"

"She went across to the village to see her mother, who is ill."

"With your permission, I presume?"

"Yes."

"Why did you permit her to go?"

"The girl's mother was very ill, and needed her daughter."

"You let her go, although I had told you I wanted to question all the servants?"

"No, it was before you told me that I gave Milly permission to have the morning off," responded Mrs. Rath quietly.

"Is that the true explanation?"

"Yes."

"Is it as true as your other statement?"

"What other statement?"

"The statement you made to me this morning when you assured me your daughter had left this house to return to her employment at Stading?" said Merrington, with a cruel smile. "That wasn't true, you know. How do you describe that untruth? As a temporary aberration of memory, or what?"

The housekeeper looked up with swift, startled eyes, and her thin hand involuntarily clutched the edge of the table in front of her, but she did not speak.

"You lied about that, you know," continued Merrington. "I've found out your daughter has been in the house all day. Why did you tell me a lie? Come, out with it!"

"You are too abrupt, Merrington," said Captain Stanhill, interposing with unexpected firmness. "You have frightened her. Come, Mrs. Rath," he said gently, "can you not give us some explanation as to why you misled us this morning?"

"Because I didn't want my daughter to be drawn into this dreadful thing," she exclaimed wildly. "I suppose it was very foolish of me," she added, in a more composed voice, as though reassured by the kindly look in Captain Stanhill's eyes, "but I really didn't think it mattered. My daughter knew nothing about the murder and as she is highly strung I did not want her to be upset."

"Where was your daughter last night when the murder was committed?" asked Merrington.

"In my room."

"Did either of you hear the scream or the shot?"

"No, my rooms are a long way from the left wing, and we were sitting with the door shut."

"Then when did you learn about the murder?"

"Very soon after it happened. One of the maidservants came and told me."

"And you say that your daughter was with you at the time, and had been with you a considerable time before?"

"Yes."

"I think that will do, Mrs. Rath, I have given you every opportunity, but you still persist in telling falsehoods. Your daughter was seen walking up the hall last night in the direction of the left wing shortly before the murder was committed. The person who saw her was the maid Milly Saker. Was that the real reason why you gave Milly leave of absence to visit her mother this morning—so that she should not tell us what she knew?"

"It is not true," gasped the housekeeper. "My daughter was not out of my rooms last night, I assure you that is the truth."

"I wouldn't believe you on your oath," retorted Merrington. "Lumbe, go and tell Caldew to bring in the girl."
