Just then some one touched me; and looking sharp round, there was the scared face of the lodger, and he whispered, "He was a-trying to get out, when I woke up and seized him. He's a'most choked me." That was a strange, wild time, as I stood there wondering what was best to be done; and do what I would I could hardly summon up the courage to go after him, though I knew it was only through my neglect that he had escaped from his room, and therefore I was bound to do something. I tried calling him at first; but the only effect that had was to make him begin muttering and walking backwards and forwards upon that giddy parapet, so that it quite chilled one's blood; for, though used enough to scaffolds at proper time and place, there was something horrid in engaging in a struggle with one who was no better than a madman, on such a roof as this. But I did not stop thinking, or I should never have done what I did, which was to get out into the gutter and walk cautiously up to the poor fellow. There--it took only a moment or two--not more, and then he bounded on to me, and we too were struggling together and rocking backwards and forwards all those feet above the ground, with certain death on one side if I slipped, or he proved too strong for me. Now we swayed this way, now that, and wet with the sweat of terror, I could feel myself weaker every moment; and the very thought of what would come at last was too horrid to bear. Once I got him back against the sloping roof, and my spirits revived; but the next moment he leaped up, as though of watch-spring, and had me down on my back upon the stone parapet, and head and shoulders over the horrid pit beneath. I could not cry out, but felt tongue and lips parched, while, with the strength of despair, I clutched his neck, and gazed with startled looks into his wild, glowering, half-shut eyes. He was muttering and talking the whole time, and every moment as I grew weaker, I could feel that I was being forced over the parapet. How many seconds it took I can't say, but it seemed to me like an hour till the time when I felt that all hope was past, and I shut my eyes that I might not see myself fall. There seemed no hope--nothing but death before me, as I lay there, with my flesh seeming to creep, and me unable to give a cry for help. All at once, though, the clutch upon me grew feeble; then it ceased altogether; and I saw poor Fred dragged away backwards; but it was some few moments before I dared try to move, when, shivering in every limb, I rolled myself off the stone parapet, and lay in a half swoon in the gutter. But the danger was over now; for two of the lodgers had dragged the poor fellow back into the attic by his legs, and after a sharp struggle he was securely tied down to the bed; but it was some time before I could work on the top of a house again without getting nervous and upset.
