He broke off and wiped his forehead.

“I beg your pardon,” said he, in a tone he evidently tried to make more natural. “I will not talk of this. I have not spoken so for years and I cannot command myself. It is enough for you to know that I saw it all, and that, to the best of my ability, I did my part. As time went on, I established myself as a physician at St. Petersburg. My family connection, although I had no near relatives, was of use to me, and in the end I had an excellent position. I was fortunate in the curing of wounds, and I had the luck to attract attention by saving the life of a near relative of the Czar. All this I looked at as so much work done for the cause. Every advance I made in influence, in wealth, in power, put me in a position to be so much the more serviceable to the great purpose of my life. Personal ambition was so swallowed up in the tremendousness of that issue that self was lost sight of. The patriot cannot remember himself in a land like Russia.

“When the execution”— He paused and turned to me with a singular smile. “You would say the assassination—when the death of General Kakonzoff was determined in our Section, no part was assigned to me, but I was high enough in the counsels of the patriots to know all that was done. He had possession of information which it was necessary to suppress. He came to St. Petersburg to present it in person. He told me frankly enough afterward that he could not trust any one because he counted upon a reward for giving the evidence himself. We were minutely informed of his plans and his movements. We had taken the precaution to replace his body-servant by one of our own men as soon as he began to make inquiries about two patriots who were suspected by the government. He had proofs which would have been fatal to them, and it was necessary to intercept these. If he had been put out of the way, our agent would easily have got possession of the papers, and without the testimony of the general our two friends were safe. The plot failed through one of those chances that make men believe in the supernatural. He was shot as he stepped out of the train at the St. Petersburg station, but the very instant our man fired, Kakonzoff stumbled. The bullet, which should have gone through his heart, passed through his lungs without killing him.”

The perfectly cool manner in which Dr. Polnitzski spoke of this incident affected me like a vertigo. To have a man who is one’s daily companion, and of whom one has become fond, speak of an assassination as if it were an ordinary occurrence, is almost like seeing him concerned himself in a murder. I lay there listening to the doctor with a fascination not unmixed with horror, despite the fact that my sympathies, as he knew beforehand, were strongly with the Nihilists. To be in sympathy with their cause and to come so near as to smell the reek of blood, so to speak, were, however, very different things.

“By a strange chance,” the doctor went on, “I was summoned to attend the wounded man, and although it was a desperate fight, I was after some days satisfied that I could save his life.”

“But,” I interrupted, “I don’t see why you should try to save his life if you were of those who doomed him to death in the first place.”

He looked at me piercingly.

“You forget,” he answered, “that I was called to him as a physician. It is the duty of a physician to save life, as it may be the duty of a patriot to take it. I was trying to do my best in both capacities. I had given the best counsel I could in the Section and, when he was on his feet, I would have shot him myself if it had seemed to my superiors that I was the best person to do it. Does it seem to you that I could have taken advantage of his helplessness, of his confidence, of my skill as a physician, to deprive him of the life which it is the aim of a physician’s existence to preserve?”

He waited for me to reply, but I had no answer to give him. The situation was one so far outside of my experience, so fantastically unreal as measured by my own life, that I could not even judge of it.

“See,” he went on, leaning forward with shining eyes and with increasing excitement of manner, “the patient puts himself into the hands of his physician, body and soul. To betray that trust is to strike at the very heart of the whole sacred art of healing. If I, as a physician, took advantage of this sick man, I not only betrayed the personal trust he put in me, but I was false to the whole principle on which the relation of doctor and patient rests. Don’t you see what a tremendous question is involved? That to harm Kakonzoff was to go beyond the limits of human possibility?”
