“He walked down the road and went into one or two liquor shops, staying for nearly half an hour in the last of them. When he came out, he staggered in his walk, and was evidently pretty well on. There was a hansom just in front of me, and he hailed it. I followed it so close that the nose of my horse was within a yard of his driver the whole way. We rattled across Waterloo Bridge and through miles of streets, until, to my astonishment, we found ourselves back in the terrace in which he had boarded. I could not imagine what his intention was in returning there; but I went on and pulled up my cab a hundred yards or so from the house. He entered it, and his hansom drove away. Give me a glass of water, if you please. My mouth gets dry with the talking.”

I handed him the glass, and he drank it down.

“That’s better,” he said. “Well, I waited for a quarter of an hour, or more, when suddenly there came a noise like people struggling inside the house. Next moment the door was flung open and two men appeared, one of whom was Drebber, and the other was a young chap whom I had never seen before. This fellow had Drebber by the collar, and when they came to the head of the steps he gave him a shove and a kick which sent him half across the road. ‘You hound!’ he cried, shaking his stick at him; ‘I’ll teach you to insult an honest girl!’ He was so hot that I think he would have thrashed Drebber with his cudgel, only that the cur staggered away down the road as fast as his legs would carry him. He ran as far as the corner, and then seeing my cab, he hailed me and jumped in. ‘Drive me to Halliday’s Private Hotel,’ said he.

“When I had him fairly inside my cab, my heart jumped so with joy that I feared lest at this last moment my aneurism might go wrong. I drove along slowly, weighing in my own mind what it was best to do. I might take him right out into the country, and there in some deserted lane have my last interview with him. I had almost decided upon this, when he solved the problem for me. The craze for drink had seized him again, and he ordered me to pull up outside a gin palace. He went in, leaving word that I should wait for him. There he remained until closing time, and when he came out he was so far gone that I knew the game was in my own hands.

“Don’t imagine that I intended to kill him in cold blood. It would only have been rigid justice if I had done so, but I could not bring myself to do it. I had long determined that he should have a show for his life if he chose to take advantage of it. Among the many billets which I have filled in America during my wandering life, I was once janitor and sweeper - out of the laboratory at York College. One day the professor was lecturing on poisons, and he showed his students some alkaloid, as he called it, which he had extracted from some South American arrow poison, and which was so powerful that the least grain meant instant death. I spotted the bottle in which this preparation was kept, and when they were all gone, I helped myself to a little of it. I was a fairly good dispenser, so I worked this alkaloid into small, soluble pills, and each pill I put in a box with a similar pill made without the poison. I determined at the time that when I had my chance my gentlemen should each have a draw out of one of these boxes, while I ate the pill that remained. It would be quite as deadly and a good deal less noisy than firing across a handkerchief. From that day I had always my pill boxes about with me, and the time had now come when I was to use them.
