It's not a nice thing to do, sitting up, in any case, for you get creepy, and nervous, and fidgetty; but when it's with a man who is off his mind, why, it's ten times worse; and there I sat with my eyes fixed upon the bed, hour after hour, half afraid lest the poor fellow should get out, or be up to any mad tricks. I suppose it was about two o'clock, and when all was about still in the streets--not even the rumble of a cab to be heard--when somehow or another things seemed to get misty and dim; the bed seemed to be rising and falling, while poor Fred's head was as if it had swelled up, and kept coming closer to me, and then went back; and then I could see nothing at all. I woke up with a start, and a horrible feeling on me that there was something wrong; then came the sound of trampling overhead, while at the same moment the light gave a flickering leap, and went out. I knew the matches were on the table, and after knocking over something I found them lying open; but it was the barley-water jug I had upset, and the matches were dripping wet. Trembling and confused, I stood for a moment not knowing what to do, and then felt my way towards the bed, with the horrid dread upon me that poor Fred might spring at me and strangle me in the dark. Something seemed to tell me that he wasn't in the bed, and therefore I expected he would be crouching down and waiting to spring at me; and in my fancy I thought I could see it all--the struggle for the mastery, and him getting me down, so that I could not cry for help. The confusion must have had something to do with it; but at all events there was I quite unnerved and shaken, as I lightly touched the bed and found all the clothes in a heap; while further search showed me that there was no one there. Then I heard again the trampling noise overhead and hurried towards the door, with both hands stretched out; when, in the dark, one went on either side of the open door, and I struck my forehead a violent blow. There was no time, though, to mind that, for I knew something was wrong upstairs, and that Fred must be at the bottom of it; so, hurrying up, I was soon at the door of the back attic, where, though it was shut, I heard enough to make me shove it open with my shoulder and dash in; for a sound came out as of two savage beasts worrying each other, and then, by the dim light from the open window, I could see two men scuffling upon the floor, while a woman sat on the bed crouched up, and holding a baby to her breast--evidently too frightened to move. As I dashed in, one of the men leaped up, and was through the window in a moment; and then, on going quickly up and leaning out, I could see it was Fred, standing right upon the parapet above the lead gutter, when my heart seemed to quite stand still, as I leaned there, expecting every moment to see the poor fellow fall on to the flags beneath--four stories; for he would have gone right into the basement yard at the back.
