"Yes; it came out better than I expected; but there were great difficulties, the usual agony between the conception and the execution. Anyhow I got it done at about seven o'clock to-night, and I thought I should like a little of the fresh air. I went out and wandered rather aimlessly about the streets; my head was full of my tale, and I didn't much notice where I was going. I got into those quiet places to the north of Oxford Street as you go west, the genteel residential neighborhood of stucco and prosperity. I turned east again without knowing it, and it was quite dark when I passed along a sombre little by-street, ill lighted and empty. I did not know at the time in the least where I was, but I found out afterwards that it was not very far from Tottenham Court Road. I strolled idly along, enjoying the stillness; on one side there seemed to be the back premises of some great shop; tier after tier of dusty windows lifted up into the night, with gibbet-like contrivances for raising heavy goods, and below large doors, fast closed and bolted, all dark and desolate. Then there came a huge pantechnicon warehouse; and over the way a grim blank wall, as forbidding as the wall of a jail, and then the headquarters of some volunteer regiment, and afterwards a passage leading to a court where wagons were standing to be hired. It was, one might almost say, a street devoid of inhabitants, and scarce a window showed the glimmer of a light. I was wondering at the strange peace and dimness there, where it must be close to some roaring main artery of London life, when suddenly I heard the noise of dashing feet tearing along the pavement at full speed, and from a narrow passage, a mews or something of that kind, a man was discharged as from a catapult under my very nose and rushed past me, flinging something from him as he ran. He was gone and down another street in an instant, almost before I knew what had happened, but I didn't much bother about him, I was watching something else. I told you he had thrown something away; well, I watched what seemed a line of flame flash through the air and fly quivering over the pavement, and in spite of myself I could not help tearing after it. The impetus lessened, and I saw something like a bright half-penny roll slower and slower, and then deflect towards the gutter, hover for a moment on the edge, and dance down into a drain. I believe I cried out in positive despair, though I hadn't the least notion what I was hunting; and then to my joy I saw that, instead of dropping into the sewer, it had fallen flat across two bars. I stooped down and picked it up and whipped it into my pocket, and I was just about to walk on when I heard again that sound of dashing footsteps. I don't know why I did it, but as a matter of fact I dived down into the mews, or whatever it was, and stood as much in the shadow as possible. A man went by with a rush a few paces from where I
