knocked over the pitcher of thil , but it didn't matter. The pitcher spring them. "We," he said, "are broke. We are finished, through. Washed up and down the drain." He added, as an afterthought, "Destitute." I looked at him. I said sourly, "You're kidding!" "Kidding." Shannon put his elbows on the table and peered at me through I said, "Bucky. Hold on, fella. I...." blue eyes like a baby, and his voice was softer than Bucky's. He said, "I don't think you understand." I felt cold, suddenly, between the shoulders. Somebody scraped a chair back. It sounded like he'd ripped the floor open, it was so quiet. I Bucky heaved the table off his lap and cursed me. "What's eating you, Bucky Shannon got up. He grinned his pleasantest grin. "Delighted. I'm I looked at Bucky. He looked hungrier than the Marshies did. We didn't Bucky got red around the ears. "Just a minute," he murmured, and Bucky had relaxed. His grey-green eyes began to gleam. He started to The curtains were yanked back suddenly. Beamish shut up. Bucky and I wouldn't die on us, because without her we'd have a sicker-looking circus than even I could stand. feet. He waved and said, "Hiya, boys." Bucky and I checked the bills, paid them, and pocketed the receipts. Bucky yawned and stretched sleepily. Bucky Shannon regarded them possessively, wiping blood from his nose. I said, "Sure," rather sourly. Bucky hiccoughed. Bucky was looking stubborn, so I shrugged. The fight had just put the topper on him. I was afraid he'd fall down the ladder and break his neck. That's why I went along. If I hadn't.... Oh, well, what's a few nightmares among friends? the smell, I think rank and sour and wild. And the sound of them, breathing and rustling in the dark, with the patient hatred walled woman's talking about a sick child. "This time," he said, "I ain't sure." Bucky was almost asleep on me. I started to slap him. And then the mist with blue, cold fire. I yelled, "Gow! Gow, the Vapor snakes! Gow—for God's sake!" I started to run, back along the passageway. Bucky weighed on me, limp I could hear Gertrude's lonely, whistling scream. I thought, " Somebody's down here. Somebody let 'em out. Somebody wants to kill us! " I tried to yell again. It strangled in my throat. I sobbed, and the sweat was thick and cold on me. One of Bucky's dragging, stumbling feet got between mine. We fell. I Bucky moaned and kicked under me. I remember hanging on and thinking, "This is it. This is it, and oh God, I'm scared!" Then I went out. II washstand—I was in my own cell—and I saw what Kanza meant. The damned snakes had done a good job. I looked like I was upholstered in Scotch plaid. I felt sick. Bucky Shannon opened the door. He looked white and grim, and there was "Jig," he said, "those vapor worms were all right when we went in. Somebody followed us down and let them out. On purpose." I hurt all over. I growled, "With that brain, son, you should go far. Nobody saw anything, of course?" Bucky shook his head. "Question is, Jig, who wants to kill us, and why?" "Beamish. He realizes he's been gypped." latch and looked at my feet. "And—uh—Jig, I...." I said, "Skip it. The next time, just don't trip me up, that's all!" like a disaster hoping to happen. To make it worse, Zurt the Jovian strong-man got hurt during the take-off, and the Mercurian cave-cat had kittens. her jaw pulsed like a toad's, and her eyes were red. "The deep swamps are angry," she whispered. "Something has been taken. They are angry, and I smell death in the wind!" could see him plainly, because he was off to one side of the crowd. He fell on his knees in the mud, making noises. It took him three or four tries to get our names out clear enough to understand. Bucky said, "Jig—it's Sam Kapper." Sam Kapper was a hunter, supplying animals to zoos and circuses and too broke, and we were pretty friendly. I hadn't seen him for three seasons. I remembered him as a bronzed, hard-bitten guy, lean and tough as a twist of tung wire. I felt sick, looking down at him. Bucky started to help him up. Kapper was crying, and he jerked all over like animals I've seen that were scared to death. Some guy leaned over and put a cigarette in his mouth and lighted it for him. I was thinking about Kapper, then, and I didn't pay much attention. I realize until later that he looked familiar. We got Kapper inside the shack. It turned out to be a cheap bar, with a the curtain in a lot of curious faces. Kapper dragged hard on the Bucky said gently, "Okay, Sam. Relax. What's the trouble?" Kapper tried to straighten up. He hadn't shaved. The lean hard lines of his face had gone slack and his eyes were bloodshot. He was covered with mud, and his mouth twitched like a sick old man's. He said thickly, "I found it. I said I'd do it, and I did. I found it and brought it out." The cigarette stub fell out of his mouth. He didn't notice it. "Help me," he said simply. "I'm scared." His mouth drooled. Bucky looked at me. Kapper was blue around the mouth. I was scared, Bucky got up. "I'll get a doctor," he said. "Stick with him." Kapper grabbed his wrist. Kapper's nails were blue and the cords in his hands Kapper's face was horrible. I felt sick, listening to him fight for air. I wanted to go for a doctor anyway, but somehow I knew it was no use. Kapper whispered, " Cansin . Male. Only one. You don't know...! Take him back." was standing there. Beamish, bent over, with his ear cocked. Kapper made a harsh strangling noise and fell across the table. Beamish never changed expression. He didn't move while Bucky felt Kapper's pulse. Bucky didn't need to say anything. We knew. "Heart?" said Beamish finally. "Yeah," said Bucky. He looked as bad as I felt. "Poor Sam." The place was awfully quiet, for that kind of a place. The bartender was a big pot-bellied swamp-edger with pale eyes and thick white hair coiled up on top of his bullet head. He was not happy. I leaned on the bar. " Lhak ," I said. He poured it, sullenly, out of a green bottle. I reached for it, casually. "That guy we brought in," I said. "He sure has a skinful. Passed out cold. What's he been spiking his drinks with?" " Selak ," said a voice in my ear. "As if you didn't know." I turned. The man who had given Kapper the cigarette was standing behind me. And I remembered him, then.
