In an agony of mind, Mr. Burwell struggled to go on, I soothing and encouraging him.
"Unless you find what I am afraid to think, but—but—yes, I must say it,—that I have not been a good man, as the world thinks, but have—O doctor, if you find that I have unknowingly harmed any human being, I want that person, or these persons, to have my fortune. Promise that."
Seeing the wild light in Burwell's eyes, and the fever that was burning him, I gave the promise asked of me, and the sick man sank back calmer.
A little later, the nurse and attendants came for the operation. As they were about to administer the ether, Burwell pushed them from him, and insisted on having brought to his bedside an iron box from the safe.
"The card is here," he said, laying his trembling hand upon the box, "you will remember your promise!"
Those were his last words, for he did not survive the operation.
Early the next morning I received this message: "The stranger of yesterday begs to see you"; and presently a gentleman of fine presence and strength of face, a tall, dark-complexioned man wearing glasses, was shown into the room.
"Mr. Burwell is dead, is he not?" were his first words.
"Who told you?"
"No one told me, but I know it, and I thank God for it."
There was something in the stranger's intense earnestness that convinced me of his right to speak thus, and I listened attentively.
"That you may have confidence in the statement I am about to make, I will first tell you who I am"; and he handed me a card that caused me to lift my eyes in wonder, for it bore a very great name, that of one of Europe's most famous savants.
"You have done me much honour, sir," I said with respectful inclination.
"On the contrary you will oblige me by considering me in your debt, and by never revealing my connection with this wretched man. I am moved to speak partly from considerations of human justice, largely in the interest of medical science. It is right for me to tell you, doctor, that your patient was beyond question the Water Street assassin."
"Impossible!" I cried.
"You will not say so when I have finished my story, which takes me back to Paris, to the time, eleven years ago, when this man was making his first visit to the French capital."
"The mysterious card!" I exclaimed.
"Ah, he has told you of his experience, but not of what befell the night before, when he first met my sister."
"Your sister?"
"Yes, it was she who gave him the card, and, in trying to befriend him, made him suffer. She was in ill health at the time, so much so that we had left our native India for extended journeyings. Alas! we delayed too long, for my sister died in New York, only a few weeks later, and I honestly believe her taking off was hastened by anxiety inspired by this man."
"Strange," I murmured, "how the life of a simple New York merchant could become entangled with that of a great lady of the East."
"Yet so it was. You must know that my sister's condition was due mainly to an over fondness for certain occult investigations, from which I had vainly tried to dissuade her. She had once befriended some adepts, who, in return, had taught her things about the soul she had better have left unlearned. At various times while with her I had seen strange things happen, but I never realized what unearthly powers were in her until that night in Paris. We were returning from a drive in the Bois; it was about ten o'clock, and the city lay beautiful around us as Paris looks on a perfect summer's night. Suddenly my sister gave a cry of pain and put her hand to her heart. Then, changing from French to the language of our country, she explained to me quickly that something frightful was taking place there, where she pointed her finger across the river, that we must go to the place at once—the driver must lash his horses—every second was precious.
"So affected was I by her intense conviction, and such confidence had I in my sister's wisdom, that I did not oppose her, but told the man to drive as she directed. The carriage fairly flew across the bridge, down the Boulevard St. Germain, then to the left, threading its way through the narrow streets that lie along the Seine. This way and that, straight ahead here, a turn there, she directing our course, never hesitating, as if drawn by some unseen power, and always urging the driver on to greater speed. Finally, we came to a black-mouthed, evil-looking alley, so narrow and roughly paved that the carriage could scarcely advance.
"'Come on!' my sister cried, springing to the ground; 'we will go on foot, we are nearly there. Thank God, we may yet be in time.'
"No one was in sight as we hurried along the dark alley, and scarcely a light was visible, but presently a smothered scream broke the silence, and, touching my arm, my sister exclaimed:—
"'There, draw your weapon, quick, and take the man at any cost!'
"So swiftly did everything happen after that that I hardly know my actions, but a few minutes later I held pinioned in my arms a man whose blows and writhings had been all in vain; for you must know that much exercise in the jungle had made me strong of limb. As soon as I had made the fellow fast I looked down and found moaning on the ground a poor woman, who explained with tears and broken words that the man had been in the very act of strangling her. Searching him I found a long-bladed knife of curious shape, and keen as a razor, which had been brought for what horrible purpose you may perhaps divine.
"Imagine my surprise, on dragging the man back to the carriage, to find, instead of the ruffianly assassin I expected, a gentleman as far as could be judged from face and manner. Fine eyes, white hands, careful speech, all the signs of refinement and the dress of a man of means.
"'How can this be?' I said to my sister in our own tongue as we drove away, I holding my prisoner on the opposite seat where he sat silent.
"'It is a kulos-man,' she said, shivering, 'it is a fiend-soul. There are a few such in the whole world, perhaps two or three in all.'
"'But he has a good face.'
"'You have not seen his real face yet; I will show it to you, presently.'
"In the strangeness of these happenings and the still greater strangeness of my sister's words, I had all but lost the power of wonder. So we sat without further word until the carriage stopped at the little château we had taken near the Parc Monteau.
"I could never properly describe what happened that night; my knowledge of these things is too limited. I simply obeyed my sister in all that she directed, and kept my eyes on this man as no hawk ever watched its prey. She began by questioning him, speaking in a kindly tone which I could ill understand. He seemed embarrassed, dazed, and professed to have no knowledge of what had occurred, or how he had come where we found him. To all my inquiries as to the woman or the crime he shook his head blankly, and thus aroused my wrath.
"'Be not angry with him, brother; he is not lying, it is the other soul.'
"She asked him about his name and country, and he replied without hesitation that he was Richard Burwell, a merchant from New York, just arrived in Paris, travelling for pleasure in Europe with his wife and daughter. This seemed reasonable, for the man spoke English, and, strangely enough, seemed to have no knowledge of French, although we both remember hearing him speak French to the woman.
"'There is no doubt,' my sister said, 'It is indeed a kulos-man; It knows that I am here, that I am Its master. Look, look!' she cried sharply, at the same time putting her eyes so close to the man's face that their fierce light seemed
