"He will not be in London," he answered doggedly. He stepped between me and the door with looks which I did not like. At the same time I felt that some allowance must be made for a man treated in this way. "I am sorry," I said, "but I cannot do what you ask. I will do this, however. If you think the delay of importance, and will give me your brother's address in Liverpool, I will undertake to post the letters to him at once." He considered the offer, eyeing me the while with the same disfavour which he had exhibited in the drawing-room. At last he said slowly-- "If you will do that?" "I will," I repeated. "I will do it immediately." He gave me the direction--"George Ritherdon, at the London and North-Western Hotel, Liverpool," and in return I gave him my own name and address. Then I parted from him, with a civil good night on either side--and little liking--the clocks striking midnight, and the servants coming in as I passed into the cool darkness of the square. Late as it was, I went straight to my club, determined that, as I had assumed the responsibility, there should be no laches on my part. There I placed the packet, together with a short note explaining how it came into my possession, in an outer envelope, and dropped the whole, duly directed and stamped, into the nearest pillar-box. I could not register it at that hour, and rather than wait until next morning, I omitted the precaution, merely requesting Mr. Ritherdon to acknowledge its receipt. Some days passed during which it may be imagined that I thought no little about my odd experience. It was the story of the Lady and the Tiger over again. I had the choice of two alternatives--at least. I might either believe the young fellow's story, which certainly had the merit of explaining in a fairly probable manner an occurrence which did not lend itself freely to explanation. Or I might disbelieve his story, plausible in its very strangeness as it was, in favour of my own vague suspicions. Which was I to do? I set out by preferring the former alternative. This, notwithstanding that I had to some extent committed myself by withholding the papers. But with each day that passed without bringing an answer from Liverpool, I leaned more and more to the other side. I began to pin my faith to the tiger, adding each morning a point to the odds in the animal's favour. So it went on until ten days had passed.
