CHAPTER XIII.

THE DISCOVERY.

Early in the morning of the same day upon which Leon had offered himself to Agnes, Madame Medjora, reading her Herald, had at last found the long-awaited personal, "Come," the signal which she had arranged with the detective. Immediately after breakfast, therefore, she had started forth to learn what had been discovered.

Arrived at the agency, she was at once ushered into the presence of
Mr. Barnes.

"Well," said she, scarcely waiting to be seated, "what have you found out?"

"I have learned everything," said Mr. Barnes, without any show of feeling.

"You have? Well, go on. Why don't you tell me?" Madame was very impatient, but the detective was in no hurry.

"I have known what I have learned for over a week, Madame Medjora," said he slowly, "and during that time I have hesitated to send for you. Even now, when you are here, I am not sure that I shall be doing the right thing to give you any information upon this subject, without first communicating with your husband."

"Ah! I see," said Madame, with a sneer, "you think he would pay you better than I. You are mistaken. I have plenty of money. My own money. What is your price?"

Mr. Barnes arose from his seat, in anger, but perfectly calm outwardly. As deferentially as though he were addressing a queen, he bowed and said:

"Madame, pardon me, but be kind enough to consider our interview at an end."

"What do you mean? You wish me to go?"

"Precisely, Madame. That is my wish."

"But you have not yet told me—ah! I see! I have made a mistake. But you will pardon me, Mr. Barnes. I did not know. How could I? I judged you by what I have heard of detectives. But you are different. I see that now, and I ask your forgiveness. You will forget my stupid words, will you?" She extended her hand cordially, and appeared truly regretful. Mr. Barnes yielded to her persuasive influence, and sat down again.

"Madame Medjora, I do not fully comprehend your motives in this matter. That is why I hesitate to speak." Mr. Barnes paused a moment. "Suppose you answer one or two questions. Will you?"

"Certainly! Ask me what you please."

"Very well, Madame! You married Dr. Medjora after his trial for murder. At that time he had little money. Am I right, then, in concluding that you married him because you loved him?"

"I loved him with my whole soul!"

"And now, do you love him as well now?" Mr. Barnes scrutinized her closely, lest her words should belie her real feeling. But her answer was sincere.

"I love him more now than I ever did. He is all the world to me!"

"Ah! I see!" Mr. Barnes communed with himself for a brief moment, then suddenly asked: "You have had no children, I believe?" Madame grew slightly paler, and answered in a low tone:

"None!"

"Just so! Now then, Madame, you of course recall the trial. It was more than hinted at that time that the Doctor had a child by his first wife. Did he ever tell you the truth about that?"

"Never!"

"Suppose that he had done so, and had confided to you the fact that rumor was right, and that there was a child. Understand I am only supposing a case! But if so, what would you have done?"

"I would have taken the little one, my husband's child, and I would have cherished it for its father's sake!"

This was a deliberate lie, but Madame uttered the words in tones of great sincerity. She was a very shrewd woman, and half-suspecting the object of the detective's questioning, did not hesitate to tell this falsehood in order to gain her own end. She succeeded, too, for after a few moments more, Mr. Barnes said:

"After all, Madame Medjora, I am merely a detective, and it is my business to take commissions such as you have intrusted to me, and work them out. I will make my report to you. With the letter which you gave me it was easy enough to make a start. I found the writer, Matilda Grath, and a particularly unprepossessing old hag she is. As is readily seen by her letter, she is ignorant of even common-school knowledge. She is simply a rough product of her surroundings, and is as untutored as when she was born. But she had a younger sister, Margaret, who was very different. This Margaret was a very attractive girl, and having some ambition, attended school until she was fairly well educated. This her elder sisters called "putting on airs" and "flyin' in the face of the Lord, tryin' to know more 'n her elders." Margaret also had numerous beaux, and this was another source of irritation to her sisters. Finally there came a young man to the neighborhood, and in the language of the people thereabout, Margaret "set her cap" for him. However, he did not marry her, but after he had left the vicinity, Margaret went to Boston, where she remained several months. When she returned she brought a baby back with her. That baby was Leon."

"Then he was her child?"

"The gossips said so, but there is no doubt in my mind that he was not. He was the child of the man to whom she had given her heart, but the mother was his lawful wife."

"Then why was the baby given to Margaret Grath?"

"Because the mother died, and the father was tried for murdering her!"

"My God! You mean that——"

"I mean that Leon's father is your husband, Dr. Medjora!"

"Impossible!" Madame wished to disbelieve exactly what she had always suspected to be the truth.

"What I tell you is fact. I never do anything by halves. In the first place I had a hint of the truth from your own suspicions. You of course had little to go on, but you loved your husband, and when a jealous eye watches the relation between the beloved one and another, it will see much. I had no doubt that you had taken your idea from your observation of the love which the Doctor bestowed upon his protégé. Next I noted the coincidence of the dates. Margaret Grath appeared with the child a very few months prior to the death of Mabel Sloane. But I obtained substantial proofs."

"What are they?"

"Matilda Grath is an avaricious old woman. Her letter was in the nature of blackmail. She did not actually know that the Doctor is the boy's father, but she adopted that idea merely from the fact that he appeared upon the scene as soon as the guardian died. Then at the auction, it appears that there was a squabble over the possession of a collie dog, and the Doctor settled the dispute by purchasing the animal, and presenting it to Leon."

"Oh! He did that?" Madame was inwardly incensed, but she quickly suppressed any expression of her emotion.

"Yes! Old Miss Grath thought this was 'queer.' Then when she subsequently learned, what she did not at first know, that Leon had been taken into the Doctor's home, her doubts vanished. This accounts for her allusion to the Doctor in the letter, and the reason why she did not write again, was that she had no proof with which to substantiate her suspicions. I instituted a search, however, and unearthed a package of old letters in a worm eaten writing-desk, upon which no bid had been offered at the auction, so that it had been thrown into the waste bin in the barn. Among these I found two, which were from the Doctor, alluding to the boy, and also a photograph of himself sent at the earnest solicitation of Margaret Grath, as one letter explains. I suppose he thought that this was the least repayment he could make for a lifelong sacrifice."

"You have those letters?" asked Madame, with some anxiety.

"I have them here," answered the detective. "Do you wish them?"

"I do!"

"I will give them to you upon one condition,—that you give them to your husband. They are perhaps more valuable to Leon, as the only evidence which would prove that he is the Doctor's son. But as the Doctor has taken him into his house, it is evident that he means to provide for him."

"I will accept your terms. My husband shall know what you have told me, and I will give him the letters to-night."

"With that understanding, I give them into your custody."

He handed a packet to Madame, who quickly placed it in her hand-satchel. Then she arose to depart. Handing him a check already signed she said:

"Please fill in the amount of my indebtedness to you."

Mr. Barnes took the check, wrote "five hundred dollars" on the proper line, and handed it back to Madame Medjora.

"Will that be satisfactory?" he asked.

"Quite!" she answered shortly, and left the office. Having accomplished her purpose she had no further need to assume a friendliness which she did not feel.

All the way home this woman's heart grew more and more bitter because of the jealous thoughts that rankled in her breast. Her love for her husband was of that selfish sort, that exacted all for herself. She wished not only to be first in his affections, but she desired to be second, third, and last. He must not love any other than herself, unless indeed it might have been a child of hers. Having been denied that boon, she could not bear to think that he had been the father of a child not hers. She hated that dead mother, and lacking opportunity to vent her spite in that direction, she transferred her venom to her offspring. She had never liked Leon, but now she despised him utterly. She thought of Lossy, the dog which her husband had bought and presented to Leon. That the Doctor should have been so solicitous for the lad, galled her. The dog had always been an object upon which she would vent her spite when it could not be known, but now she would give some open evidence of her displeasure.

As she entered the hallway at home, imagine her delight to see Lossy, poor dog, sitting down idly tearing a fine lace handkerchief with his teeth. It seemed to her that Providence offered her an excuse for what she contemplated. She called the dog to her, and the faithful, unsuspecting creature followed her up the stairs to his doom. She went into the laboratory, knowing that both the Doctor and Leon were out, and readily found a bottle marked "Aconite."

She sat upon a low bench and called Lossy. The confiding beast went to her, and, raising himself, planted his forepaws in her lap. He would have kissed her face, but she prevented him. Grasping his jaws in her powerful hands she forced them open, and poured the entire contents of the bottle into his mouth, holding his jaws apart until he was forced to swallow the liquid. Then she released him, and he ran to that asylum of refuge and safety, his master's room. Alas, that master was away, courting! Thus Lossy's fate was sealed!

Madame awaited for Leon's return, anxious to gloat over his grief at the death of his pet, and it was for this, and to carry out another design, that she went to his room while he was ministering to his dog. Before she could fulfil her other project her husband, having returned home, interrupted them, having been attracted by the noise from Leon's room.

When she left them Madame went to her own apartment, and after the death of the dog, Dr. Medjora followed her there, determined to discover the whole truth. As he entered she arose to meet him, facing him with an undaunted air.

"Cora," demanded the Doctor, "how dared you commit such a hideous crime? Why did you poison that dog?"

"Because it was my pleasure to do so!"

"Your pleasure to deprive a poor dumb brute of life? You should be ashamed to make such a confession!"

"I am not the only one who might make confessions!"

"What do you mean?" The Doctor instantly realized that a covert threat lay hidden in her words.

"You have deceived me," cried his wife, at last giving full play to her anger. "For years you have lied to me. But at last I know everything. I know who Leon is!"

"Do you?" The man was exasperatingly calm. He folded his arms and, gazing coldly upon the wrathful woman, added, "What is it that you think you know?"

"I do not think! I tell you I know! You brought him here, calling him a poor boy whom you wished to befriend. That was a lie! He is your own child!"

"How do you know that?"

"I hired a detective. He found out the whole hideous truth. I have your letters for proof, so you need not attempt denial."

"So you have found letters? Are they genuine? Let me see them?"

"I am not such a fool as that. I have hidden them where you cannot find them. I have a better use for them than to give them to you!"

"Indeed, and may I ask what use you intend to make of them?"

"I mean to take them to Judge Dudley, and to his daughter Agnes! Ha!
That idea does not please you, does it?"

"With what purpose would you show them the letters?"

"I know what you are aiming at! I am not the fool that you think! I have studied you, and watched you all these years, and I understand you very well. You wish Leon and Agnes to be married?"

"I do! What of it?"

"What of it? It shall never be! That shall be my vengeance for your long deception. I will prevent that marriage if it cost me my life!"

"If you dare to interfere with my plans it may cost you your life!" The words were said in threatening tones, which at any other time would have cowed Madame, but now she had thrown aside her mask, and could not be stayed from her purpose. She answered haughtily, and with a tantalizing sneer:

"No! No! My fine Doctor! You cannot rid yourself of me, as you did of
Mabel Sloane! I will not drink your poison!"

"Woman! Beware!" He grasped her wrists, but with a wrench she freed herself, and stepping back spoke wildly on:

"Yes! You can strangle me perhaps! You are strong, and I am only a woman. But, before I die, I will frustrate your grand scheme to marry this miserable son of yours to an aristocrat. When I tell Judge Dudley that the boy is yours, he will hesitate to admit the son of a murderer into his family. For though he obtained your acquittal, and though he has been your friend for so many years, mark me, he will decline an alliance with one who was so near the gallows!"

She paused to note the effect of her words, a slight fear entering her heart, as she thought that perhaps she had said too much. To her amazement, her husband, without answering a single word, turned and left the room.

Leon lay beside his dog so long, that at last the twilight closed in, and slowly the light of day faded until darkness surrounded him.

He heard the strokes upon the Japanese bronze which summoned him to dinner, but he did not heed. It seemed to him that he would never care to eat again. Through the weary hours of the night Leon was struggling against suggestion. It will be remembered that, in his little story, he likened the killing of a dog to murder. Therefore in his opinion the killing of Lossy, was a murderous act; and thus the thought of murder occupied his mind. He considered Madame a self-confessed criminal, and, as such, justice demanded that she should be punished. But the justice of man did not include her act within the statutes of the criminal code. She had killed Lossy, but, were he to demand her punishment at the hands of the law, the law's representatives would laugh at him. But punished she should be, of that he was already determined.

If it seem to you that Leon over-estimated the wrong which had been done to him, then one of two things is true. Either you have never loved and been loved by a dog, or else you forget that the love lavished upon him by Lossy was all the affection which Leon had enjoyed for years. To the lad, his collie was his dearest friend. In the grief for his death he had even forgotten for the time his human love, Agnes. Thus it was that the idea of meting out justice against Madame himself, having once entered his mind, took a firm hold upon him.

How should he accomplish it? What should her punishment be? What is the usual punishment of murder? Death! A chill passed over him at the thought. Yet was not Lossy's life as dear to him, as Madame Medjora's was to her? Then why should not she lose her life in payment for the crime which she had committed, her victim being a defenceless and confiding dog? Leon pictured to himself how she had accomplished the deed. He saw, in his mind, the poor creature going to her, and thus placing himself within her power. The thought maddened him, and setting his teeth together he muttered audibly:

"She shall die!"

Then his brain sought some way to compass such an end with safety to himself, and before long he had concocted a scheme of devilish ingenuity. His knowledge of chemistry warned him that poisons could be traced in the tissues of the body after death, and that such means would be suicidal.

"But suppose she were to die a natural death? Then, not even suspicion would be aroused."

That was the idea. He must convey to her the germs of some deadly disease from which she would be apt to die. Then the post-mortem would show nothing out of the common. There would be no way to detect how the disease had been contracted. The attending physician would certify that the death was due to a known disease, and an autopsy, if held, would substantiate his statements.

What disease should he choose? Asiatic cholera? He had some pure cultures in a tube in the laboratory. But no! That would not serve his purpose. Cholera is such an uncommon and dangerous malady, that the Board of Health would strictly investigate a sporadic case. It might not be difficult to trace the fact that he had obtained the germs from the European laboratory whence they had been sent to Dr. Medjora for experimental purposes. It would be safer to select some disease of frequent occurrence. He had the germs of diphtheria also, in the form of a pure culture. Should he use them? It would not be sure that the woman would die, but at any rate she might, and surely she would suffer. Yes! He would cause her to contract diphtheria. But how to proceed? Ah! He would use chloroform upon her in her natural sleep, and thus obtain the opportunity for his inoculation.

And so the idea grew, and his plans were arranged and perfected hour after hour, until at last midnight had arrived. Stealthily he left his room and went towards the Doctor's study. Arrived there, he was about to cross and enter the laboratory, when his attention was attracted by a line of light under the door. Some one was evidently in the laboratory. Leon slipped behind a curtain and waited. The minutes passed tediously, but at last the door opened, and there appeared Dr. Medjora, only partly dressed, his feet slippered. In one hand he carried a night lamp, and in the other he held a bottle and a test tube. Of this Leon was certain. Closing the door of the laboratory, the Doctor crossed the study and went out into the hall. Leon stole after him, and saw him start up the stairs. He watched until, as the Doctor ascended, the light gradually disappeared. Then he heard footsteps overhead, and knew that the Doctor had gone to his own room. Madame slept at the other end of the dwelling.

"Some experiment which he is studying out," muttered Leon, and proceeded with his own grim purpose. He went into the laboratory, and lighted a lamp which was on the bench. He searched the closet where the drugs were kept, but the chloroform bottle was missing. He turned to the rack where he had left the tube in which the diphtheria bacillus had been cultivated, but that also could not be found.

In a moment, realizing that the means of committing the contemplated crime had in some mysterious way been taken from him, he awoke from the delirium of his thoughts, which had been brought on by his grief at the death of his dog, and he fervently thanked the fortune which had saved him from committing murder. Like a culprit, he returned stealthily to his room, head down, and there he sat at the window, looking out at the stars, grateful that he could do so, free from that dread secret which might have been his. He was saved!

On the next morning, however, Leon was horrified to hear that Madame had been suddenly taken ill, and that the malady was diphtheria, in its most virulent form. He could not understand it, but he was more than glad that his own conscience was free from stain.

Two days later, Madame Medjora succumbed to the disease, which is often fatal when it attacks one of her age; and so she went to her long account, with her sins upon her head.
