[Illustration: _Presently there was not one Robot, but three!_] [Sidenote: From somewhere out of Time come a swarm of Robots who inflict on New York the awful vengeance of the diabolical cripple Tugh.] The extraordinary incidents began about 1 A.M. in the night of June 8-9, 1935. I was walking through Patton Place, in New York City, with my friend Larry Gregory. My name is George Rankin. My business--and Larry's--are details quite unimportant to this narrative. We had been friends in college. Both of us were working in New York; and with all our relatives in the middle west we were sharing an apartment on this Patton Place--a short crooked, little-known street of not particularly impressive residential buildings lying near the section known as Greenwich Village, where towering office buildings of the business districts encroach close upon it. This night at 1 A. M. it was deserted. A taxi stood at a corner; its chauffeur had left it there, and evidently gone to a nearby lunch room. The street lights were, as always, inadequate. The night was sultry and dark, with a leaden sky and a breathless humidity that presaged a thunder storm. The houses were mostly unlighted at this hour. There was an occasional apartment house among them, but mostly they were low, ramshackle affairs of brick and stone. We were still three blocks from our apartment when without warning the incidents began which were to plunge us and all the city into disaster. We were upon the threshold of a mystery weird and strange, but we did not know it. Mysterious portals were swinging to engulf us. And all unknowing, we walked into them. Larry was saying, "Wish we would get a storm to clear this air--_what the devil?_ George, did you hear that?" * * * * * We stood listening. There had sounded a choking, muffled scream. We were midway in the block. There was not a pedestrian in sight, nor any vehicle save the abandoned taxi at the corner. "A woman," he said. "Did it come from this house?" We were standing before a three-story brick residence. All its windows were dark. There was a front stoop of several steps, and a basement entryway. The windows were all closed, and the place had the look of being unoccupied. "Not in there, Larry," I answered. "It's closed for the summer--" But I got no further; we heard it again. And this time it sounded, not like a scream, but like a woman's voice calling to attract our attention. "George! Look there!" Larry cried. The glow from a street light illumined the basement entryway, and behind one of the dark windows a girl's face was pressed against the pane. Larry stood gripping me, then drew me forward and down the steps of the entryway. There was a girl in the front basement room. Darkness was behind her, but we could see her white frightened face close to the glass. She tapped on the pane, and in the silence we heard her muffled voice: "Let me out! Oh, let me get out!"
