She said the same thing to Mr. Upton at luncheon in his private sitting-room at the hotel, whereupon he again assured her that he had no desire to know a dead man’s secrets. He had found his boy; that was quite enough for him, and he was able to deliver himself the more freely on the subject since Pocket was not at table, but in bed making up for lost sleep. Not only had he succeeded in finding his son, but he had found him without the aid of police or press, and so not more than a dozen people in the world knew that he had ever disappeared. Mr. Upton explained why he had deemed it essential to keep the matter from his wife’s ears, and added almost equally good reasons for continuing to hush it up on the boy’s account if only it were possible to do so; but would it be possible to Phillida to exclude from her evidence at the inquest all mention of so recent a visitor at her uncle’s house? Phillida promised to do her best, and it proved not only possible but easy. She was questioned as to the habits of the deceased so far as they explained his presence on the Embankment at such a very early hour, but that was all. Asked if she knew of a single person who could conceivably have borne such a grudge against Dr. Baumgartner as to wish to take his life, the witness answered in the negative, and the coroner bowed as much as to say that of course they all knew the character of the murder, but he had put the question for form’s sake. The only one which caused her a moment’s hesitation arose from a previous answer, which connected the doctor’s early ramblings with his hobby of instantaneous photography. Had he his camera with him that morning? Phillida thought so. Why? Well, he always did take it out, and it certainly was not in the house. Mr. Upton wiped his forehead, for he knew that his boy’s name had been on the tip of the witness’s tongue. And there was a sensation in court as well; for here at last was a bone for the detectives, who obtained a minute description of the missing camera, but grumbled openly that they had not heard of it before.

“They never told me they hadn’t got it,” explained Phillida to the coroner, who made her his courteous bow, and permitted her to leave the court on the conclusion of her evidence.

On the stairs Mr. Upton paid her compliments that made her wince as much as the crude grip of his hand; but he was tact itself compared with his friend Mr. Thrush, who sought an interview in order to ply the poor girl there and then with far more searching questions than she had been required to answer upon oath. She could only look at Mr. Upton in a way that secured his peppery intervention in a moment. The two men had scarcely seen each other since the morning, and the ironmaster thought they had enough to say to each other without bothering Miss Platts just then; they accordingly adjourned to Glasshouse Street, and Phillida was to have gone on to the hotel; but she made them drop her at a shop near Sloane Square on the pretext of seeing about her mourning.

Phillida had promised to drive straight back to Trafalgar Square and order tea for herself if Tony had not appeared; but she did not drive straight back. She had a curious desire to see the place where the murder had been committed. It had come upon her at the inquest, while listening to the constable who had found the body, her predecessor in the witness-box. She had failed to follow his evidence. He had described that portion of his beat which had brought him almost on the scene of the murder, almost at the moment of its commission. It included only the short section of Cheyne Walk between Oakley Street and Cheyne Row. The houses at this point are divided from the Embankment by the narrow garden which contains the Carlyle statue. He had turned up Cheyne Row, at the back of the statue, but before turning he had noticed a man on the seat facing the river on the far side of the garden. The man was sitting down, but he was said to have turned round and watched the policeman as he passed along Cheyne Walk. There might have been a second man lying on that seat, or crouching on the flags between the seat and the parapet, but he would have been invisible from the beat. Not another creature was in sight anywhere. Yet the policeman swore that he had not proceeded a dozen yards up Cheyne Row before the shot was fired. He had turned round actually in time to see the puff of smoke dispersing over the parapet. It was all he saw. He had found the deceased lying in a heap, nearer the seat than the parapet, but between the two. Not another soul did he see, or had he seen. And he had not neglected to look over the parapet into the river, and along the foreshore in both directions, without discovering sign or trace of human being.

Such was the story which Phillida found so hard to credit that she proceeded to the spot in order to go over the ground for her own satisfaction. This did not make it easier to understand. It had come on to rain heavily while she was in the shop; the shining Embankment was again practically deserted, and she was able to carry out her experiment without exciting observation. She took a dozen steps up Cheyne Row, pretended she heard the shot, turned sharp round, and quite realised that from where she was the body could not have been seen, hidden as it must have been by the seat, which itself was almost hidden by the long and narrow island of enclosed garden. But a running man could have been seen through the garden, even if he stooped as he ran, and the murderer must have run like the wind to get away as he had done. The gates through the garden, back and front of the statue, had not been opened for the day when the murder took place, so Phillida in her turn made a half-circuit of the island to get to the spot where the body had been found, but without taking her eyes off the spot until she reached it. No! It was as she had thought all along; by nothing short of a miracle could the assassin have escaped observation if the policeman had eyes in his head and had acted as he swore he had done. He might have dashed into the garden, when the policeman was at his furthest point distant, if the gates had been open as they were now; but they had been locked, and he could not have scaled them unobserved. Neither would it have been possible to take a header into the river with the foreshore as described by the same witness. Yet the murderer had either done one of these things, or the flags of the Embankment had opened and swallowed him.

The girl stood on the very spot where the murdered man must have fallen, and in her utter perplexity it was no longer the tragedy but the problem which engrossed her mind. What had happened, had happened; but how could it have happened? She raised her umbrella and peered through the rain at a red pile of many-windowed flats; had that Argus of the hundred eyes been sleeping without one of them open at the time? Her own eyes fell as far as the black statue in the narrow garden, standing out hi the rain, like the greenery about its granite base, as though the blackened bronze were polished marble. How lifelike the colossal scholar in his homely garb! How scornful and how shrewd the fixed eternal gaze across his own old Father Thames! It assumed another character as the girl gazed in her turn, she seemed to intercept that stony stare, to distract it from the river to herself, and to her fevered fancy the grim lips smiled contemptuously on her and her quandary. He knew—he knew—those grim old eyes had seen it all, and still they stared and smiled as much as to say: “You are looking the wrong way! Look where I am looking; that way lies the truth you are poor fool enough to want to know!”

And Phillida turned her back towards the shiny statue, and looked over the wet parapet, almost expecting to see something, but never dreaming of what she actually saw. The tide, which must have been coming in that early morning, was now going out, and between the Embankment masonry and the river there was again a draggled ribbon of shelving foreshore, black as on some volcanic coast; and between land and water, at a point that would necessarily have been submerged for the last eight or nine hours, a small object was being laid more bare by every receding wavelet. It was black and square, perhaps the size of two large cigar-boxes side by side; and it had one long, thin, reddish tentacle, finishing in a bulb that moved about gently in the rain-pocked water.

Phillida felt the parapet strike cold and wet through her rain-coat sleeves as she leant far over to make doubly sure what she object was; but indeed she had not a moment’s doubt but that it was the missing camera of the murdered man.

CHAPTER XXI.
AFTER THE FAIR

Mr. Upton was dumfoundered when the top-floor door in Glasshouse Street was opened before Eugene Thrush could insert his key; for it was the sombre Mullins who admitted the gentleman as though nothing had happened to him except a fairly recent shave.
