Back in the hall, I tried two more doors, both locked. A third opened, and I found myself looking down the cellar stairs. They were steep and dark like cellar stairs always seem to be but they might be the way out. I felt for a light switch, flipped it on. A weak illumination showed me a patch of damp-looking floor at the foot of the steps. It still wasn't inviting, but I went down. There was an oil furnace in the center of the room, with dusty duct work spidering out across the ceiling; some heavy packing cases of rough wood were stacked along one wall, and at the far side of the room there was a boarded-up coal bin--but no cellar door. I turned to go back up and heard a sound and froze. Somewhere a cockroach scuttled briefly. Then I heard the sound again: a faint grinding of stone against stone. I peered through the cob-webbed shadows, my mouth suddenly dry. There was nothing. The thing for me to do was to get up the stairs fast, batter the iron trellis out of that kitchen window, and run like hell. The trouble was, I had to move to do it, and the sound of my own steps was so loud it was paralyzing. Compared to this, the shock of stumbling over the gun was just a mild kick. Ordinarily I didn't believe in things that went bump in the night, but this time I was hearing the bumps myself, and all I could think about was Edgar Allan Poe and his cheery tales about people who got themselves buried before they were thoroughly dead. There was another sound, then a sharp snap, and I saw light spring up from a crack that opened across the floor in the shadowy corner. That was enough for me. I jumped for the stairs, took them three at a time, and banged through the kitchen door. I grabbed up a chair, swung it up, and slammed it against the trellis. It bounced back and cracked me across the mouth. I dropped it, tasting blood. Maybe that was what I needed. The panic faded before a stronger emotion--anger. I turned and barged along the dark hall to the living room--and lights suddenly went on. I whirled and saw Foster standing in the hall doorway, fully dressed. "OK, Foster!" I yelled. "Just show me the way out of here." Foster held my eyes, his face tense. "Calm yourself, Mr. Legion," he said softly. "What happened here?" "Get over there to that gun," I snapped, nodding toward the .30 calibre on the bar. "Disarm it, and then get the front door open. I'm leaving." Foster's eyes flicked over the clothes I was wearing. "So I see," he said. He looked me in the face again. "What is it that's frightened you, Legion?" "Don't act so damned innocent," I said. "Or am I supposed to get the idea the brownies set up that booby trap while you were asleep?" His eyes went to the gun and his expression tightened. "It's mine," he said. "It's an automatic arrangement. Something's activated it--and without sounding my alarm. You haven't been outside, have you?" "How could I--"
