I became glass-like and saw within myself. There were two selves in me. One, the former D-503, Number D-503; and the other.... Before, that other used only to show his hairy paws from time to time, but now the whole other self left his shell. That shell was breaking, and in a moment.... Grasping with all my strength the last straw (the arms of the chair), I asked loudly (so as to hear my first self), "Where, where did you get this poison?" "Oh, this? A physician, one of my...." "'One of my! one of my' what?" And my other self jumped up suddenly and yelled: "I won't allow it! I want no one but me.... I shall kill any one who.... Because I.... You." ... I saw my other self grasp her rudely with his hairy paws, tear the silk, and put his teeth in her flesh!... I remember exactly, his teeth!... I do not remember how, but I-330 slipped away and I saw her straightened, her head raised high, her eyes overlain by that cursed impenetrable curtain. She stood leaning with her back against the closet door and listening to me. I remember I was on the floor; I embraced her limbs, kissed her knees and cried supplicatingly, "At once, right away, right away." Sharp teeth.... The sharp mocking triangle of the brows.... She bent over and in silence unbuttoned my badge. "Yes, yes, dear--dear." I began hastily to remove my unif. But I-330, silent as before, lifted my badge to my eyes, showing me the clock upon it. It was twenty-two-twenty-five. I became cold. I knew what it meant to be out in the street after twenty-two-thirty. My insanity disappeared at once. I was again I. I saw clearly one thing: I hated her, hated her, hated-- ... Without saying good-bye, without looking back, I ran out of the room. Hurriedly trying to fasten the badge back in its place, I ran down the stairs (I was afraid lest some one notice me in the elevator), and jumped out into a deserted street. Everything was in its place; life so simple, ordinary, orderly. Glittering glass houses, pale glass sky, a greenish, motionless night. But under that cool glass something wild, something red and hairy, was silently seething. I was gasping for breath but I continued to run, so as not to be late. Suddenly I felt that my badge which I had hurriedly pinned on, was detaching itself; it came off and fell to the sidewalk. I bent over to pick it up and in the momentary silence I heard somebody's steps. I turned. Someone small and hunched was disappearing around the corner. At least so it seemed. I started to run as fast as I could. The wind whistled in my ears. At the entrance of my house I stopped and looked at the clock; one minute to twenty-two-thirty! I listened; nobody behind. It was my foolish imagination, the effect of the poison.
