“The man was dressed in the garb of a clergyman. He was a large, powerfully built fellow, strength of mind and body marked all over him. He nodded and smiled at me as he drew a long breath to recover his wind and sat down. The dog slunk under the seat, where it lay watching me with steady eyes.

“I cowered in my corner in terror. Had I wished to speak, I could not have done so. The sight of one of my all-powerful foes, visible for the first time, fascinated me. I could not take my eyes from him. Occasionally he looked up at me from his newspaper with a slow, quiet smile which seemed to say: ‘All right, my friend. I’ll deal with you presently.’

“The train clanged and banged over the switches and gathered speed for its rush into the dark night and the loneliness of the countryside. Minute after minute I sat there in panic, watching him, agonized every now and then by that terrible sure smile with which he glanced at me. The silence in the carriage was the oppressive silence which awaits a tragedy to break it with a lightning-flash.

“Mile after mile the train raced on, and nothing happened. The suspense was maddening me. My lips were dry. My tongue stuck to the roof of my mouth. I could feel a cold sweat beading my forehead. I took out my handkerchief to wipe it, and a piece of paper fluttered to the ground, close to his feet. I recognized it. It was the second warning. Before I could move, the man bent to pick it up. He handed it to me with that meaning smile and said, with awful quietness: ‘Are you prepared?’

“I started with terror and felt something hurt the hand which all the time had been gripping the revolver in my pocket. It was the tense pressure of my finger on the weapon.

“The man nodded and smiled at me again. I gasped, feeling certain that my hour had come. With the fascination of a man trapped and bound, I saw him bend sideways and put his hand into his hip pocket. Instantly—I know not how—there was a deafening report in the carriage, and a film of smoke floated between me and him. He sank to the floor. He rolled slightly with his last gasp, his arm outflung. I had killed him! I stood fixed with horror. In his hand was—not a revolver, but a tobacco-pipe.

“For a moment my senses left me. I knew nothing. I was brought to consciousness by a sharp pain in my leg. The white dog held me in a savage grip, growling in a manner frightful to hear. Frenzy overcame me; I kicked and fought in vain. Then, suddenly recollecting the revolver in my hand, I pressed it to his head and fired. I was free. Free? No, trapped in the swaying carriage splashed with blood, its floor heaped with the large body of the man I had killed. The train was racing along at top speed. In five or ten minutes more we should stop and the crime would be discovered. Mad with horror, I rushed to the door, opened it, flung myself into the black night. I remember the roar of the train passing me as I rolled down the embankment, have an impression of a bright light whisked away, and then I lost consciousness.

“When my senses returned, I saw the light in your house. Clambering over a wall, I made my way to it, fainting, scarce able to walk, but frantic, it seemed to me, for help. You kindly took me in. For the moment I have respite, but ‘they’ have triumphed. By their cunning manipulation of the forces behind Life, I have been tricked into murdering one who to all outward semblance was an innocent man. In a day or two I shall be standing in the dock, and finally my life will be violently cut short by my fellow-men, accompanied by every circumstance of ignominy. Fully, indeed, are they revenged!

“Now, sir, you know my story; and if, after hearing it, you care to call in the local police——”
