guessed that one particular door I had seen but once would be open; the rest I left to chance. With my heart thumping madly I fled up the stairs, and flung myself against the door; it yielded, and I stumbled through on to the roof of the prison. I could hear down below me a great hubbub, but the roar of the flames had subsided somewhat, and I knew that the fire had been conquered. That meant for me a shorter time in which to make good my escape. I went slipping and sliding along the roof, half wishing myself back inside the prison, and wondering how I should get from that dizzy height to the ground. Fortunately I was young, and fit, and strong, and they had put me to the hardest work in the prison for those first months, thereby hardening my muscles to their own undoing; and I was active as a cat. After lying on the roof for what seemed a long time—until, in fact, the hubbub below had almost subsided entirely—I determined that I could afford to wait no longer. I raised my head where I lay and peered over the edge, as I have said, just as the great clock struck four. I looked straight into the open mouth of a rain-water pipe a few inches below me. It was almost full daylight by this time, but a hazy, misty morning. I worked my way to the very edge of the roof, and lay along it; then I got my arms over the edge and gripped the broad top of the pipe. There could be no half measures about such a matter; I threw myself over bodily, and dropped to the stretch of my arms, and hung there. Then I quickly lowered one hand and gripped the smooth, round pipe, and began to slide down. I remember wondering if by some fatality I should drop into the arms of an expectant warder. But that didn't happen. I reached the ground in safety and crouched there, waiting; there was still the outer wall to scale. In that I was less fortunate, for although in the grey light I made the circuit of it inside twice over, I failed to discover anything by which I could mount. But at last I came upon a shed that was used for storing the oakum, picked and unpicked; it had a heavy padlock on the wooden door, and the roof of the shed inclined at an angle against the high wall. It was my only chance, and there was but one way to do it. I stepped back a few paces, and took a running leap for the edge of the roof, jumping for the padlock. I tried three times, and the third time I got my foot upon the padlock, and caught the gutter with my hands. Exerting all my strength, I drew myself up until I lay flat upon the shelving roof of the shed, scrambled up that, and stood upright against the outer wall,
