you weren't afraid of them, were you?" Extensive research did not uncover any evidence that the U.S. copyright on this publication was renewed.] Of course using live bait is the best way to lure dangerous alien animals ... unless it turns out that you are the bait! "No, sir. No, because...." "We're somewhat to the south, I think," Ri said, bending over the crude "What are you going to do?" Ri asked, terrified. "Why, I'm going to tie the rope around your waist and stake you out as bait." "No!" "Oh, come now. When the farn beast hears you scream—you Delicately, Extrone raised a hand to his beard. "I'd hate to lose a day crossing the ridge," he said. "Yes, sir," Ri said. Suddenly he threw back his head. "Listen!" "You'll be safe," Extrone said, studying his face with amusement. "I'll shoot the animal before it reaches you." Ri gulped for air. "But ... if there should be more than one?" were trembling. "It's not me you want to do this to. It's Mia, sir. "He what?" Extrone demanded, leaning forward intently. Ri breathed with a gurgling sound. "He said he ought to kill you, sir. That's what he said. I heard him, sir. He said he ought to kill you. He's the one you ought to use for bait. Then if there was an accident, sir, it wouldn't matter, because he said he ought to kill you. I wouldn't...." Mia glanced nervously over his shoulder. "It's that damned pilot's Ri shrugged hopelessly. us." Ri cleared his throat nervously. "Maybe you're right." "It's the Hunting Club he don't like." "Wait," Ri begged, fighting off the rope with his hands. "You don't want to use me, sir. Not after I told you.... Please, sir. If anything should happen to me.... Please, sir. Don't do it." then, I wouldn't be one of his guides. Why didn't he hire somebody else?" "Tie it," Extrone ordered. "No, we better go on. He may have sent a spy in." They pushed on, being careful to blaze the trees, because they were not professional guides. Ri was almost slobbering in fear. "We don't want to get too near," Ri said after toiling through the "So?" Ri said. "But who are they?" It was Mia's turn to shrug. "Whoever they were, they couldn't have been hunters. They'd have kept the secret better." "We didn't do so damned well." "We didn't have a chance," Mia objected. "Everybody and his brother had Extrone dug his boot cleats into the tree, braced himself. "I like this. There's more excitement in waiting like this than in anything I know." too. That was our mistake. The pilot must have been the one who told Extrone we'd hunted this area." "I didn't think a Club pilot would do that." I didn't tell Extrone, if that's what you're thinking," Mia said. Ri's mouth twisted. "I didn't say you did." "Listen," Mia said in a hoarse whisper. "I just thought. Listen. To hell with how he found out. Here's the point. Maybe he'll shoot us, too, when the hunt's over." Ri licked his lips. "No. He wouldn't do that. We're not—not just anybody. He couldn't kill us like that. Not even him . And besides, why would he want to do that? It wouldn't do any good to shoot us. Too Ri, below, whimpered childishly and began to retreat toward the tether tree, his eyes wide. "There's a lot of satisfaction in fooling them, too," Extrone said. "Making them come to your bait, where you can get at them." He opened his right hand. "Choose your ground, set your trap. Bait it." He snapped his hand into a fist, held the fist up before his eyes, imprisoning the idea. "Spring the trap when the quarry is inside. Clever. That makes the waiting more interesting. Waiting to see if they really will come to your bait." Lin shifted, staring toward the forest. "I've always liked to hunt," Extrone said. "More than anything else, I "No," Extrone argued. "People should hunt for the love of hunting." "Killing?" "Hunting," Extrone repeated harshly. The farn beast coughed. Another answered. They were very near, and there was a noise of crackling underbrush. "He's good bait," Extrone said. "He's fat enough and he knows how to scream good." Ri had stopped screaming he was huddled against the tree, fearfully eying the forest across from the watering hole. "Wait," Extrone said. "Let's see what they do." He had not moved the rifle. He was tense, bent forward, his eyes slitted, his breath beginning to sound like an asthmatic pump. Extrone's face looked much too innocent. "How did it get there, gentlemen? Why wasn't it destroyed?" waited, frozen, his eyes staring at the farn beast in fascination. The farn beast plunged into the water, which was shallow, and, throwing "Watch! Watch!" Extrone cried gleefully. And then the aliens sprang their trap. Extrone held back the flap of the tent. "Won't you come in?" he asked without any politeness whatever. Ri obeyed the order. Ri looked away from his face. Ri waited uneasily, not answering. Extrone's lip twisted in wry amusement. "If I had waited until it was safe for me to hunt on an alien planet, I would not have been able to "Get out!" Extrone said. "It makes you think," Mia added. He twitched. "I'm afraid. I'm afraid "No," Ri said stubbornly. "Listen," Mia pleaded. "No," Ri said. "Even if we tried to tell them, they wouldn't listen. Everybody would plotting against him. Not even at first. I think they helped "No?" Mia challenged. "Couldn't we? Not today, but what about tomorrow? "The people won't support them," Ri answered woodenly. learning that he was getting ready to invade them, but more to keep them from exposing him like we were, so easy." "No!" Ri snapped. "It was to keep the natural economic balance." "You know that's not right." their loyalties. To keep them from revolt again. They'd be ready to believe us, then. He'll have a hard enough time without people running around trying to tell the truth." "You're wrong. He's not like that. I know you're wrong." guess?" Ri swallowed sickly. "Remember our guide? To keep our hunting territory a secret?" in the middle of a radio broadcast, sir." "I don't want to listen to your gabbling when I'm hunting!" Extrone find out what they want, first. I don't want to be bothered unless it's important." "Look," Extrone said. "If that's the case, why do we bother tracking them? Why not make them come to us?" "They're too unpredictable. It wouldn't be safe. I'd rather have surprise on our side." "You don't seem to see what I mean," Extrone said. " We won't be the—ah—the bait." "Oh?" "Let's get back to the column." Ri twisted at the grass shoot, broke it off, worried and unhappy. "What's he want to see me for?"
