Part 45 (2/2)

”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 j.a.panese 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 pa.s.sed 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 compa.s.s 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 pa.s.sed 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 succ.u.mbed 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.
