Ri glanced nervously at Lin out of the tail of his eye. unless it turns out that you are the bait! Lin's face was impassive. "Of me." Extrone asked, "Is there a pass?" bait." There was perspiration trickling down Ri's forehead, a single drop, creeping toward his nose. "You'll be safe," Extrone said, studying his face with amusement. "I'll Extrone raised his eyebrows. Ri gulped for air. "But ... if there should be more than one?" Extrone shrugged. "I—Look, sir. Listen to me." Ri's lips were bloodless and his hands were trembling. "It's not me you want to do this to. It's Mia, sir. He "He what?" Extrone demanded, leaning forward intently. He's the one you ought to use for bait. Then if there was an accident, fault for setting us down on this side. I told him it was the other side. I told him so." Ri shrugged hopelessly. Extrone said, "Which one is he?" Mia said, "I don't think he even saw a blast area over here. I think he wanted to get us in trouble." Extrone aimed carefully and fired, full charge, then lowered the rifle "That's what I mean. The pilot don't like businessmen. He had it in for 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." asked. "You think it's their blast?" "So?" Ri said. "But who are they?" Extrone laughed nervously. "He must have heard." Extrone dug his boot cleats into the tree, braced himself.

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 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. "No," Extrone argued. "People should hunt for the love of hunting." "Hunting," Extrone repeated harshly. "He's good bait," Extrone said. "He's fat enough and he knows how to Ri had stopped screaming he was huddled against the tree, fearfully eying the forest across from the watering hole. "What in hell do you want?" Extrone asked. "Wait," Extrone said. "Let's see what they do." He had not moved Extrone's face looked much too innocent. "How did it get there, "So?" Extrone mocked. "You'll destroy this one, too," Extrone said. Extrone said, "To begin with, they probably don't even know I'm here. without any politeness whatever. Ri obeyed the order. Extrone narrowed his eyes. "I see by your eyes that you are Ri glanced nervously around the tent, his sharp eyes avoiding Extrone's glittering ones. "Few people have seen them, sir." "Oh?" Extrone questioned mildly. "I wouldn't say that. I understand Ri waited uneasily, not answering. you had killed the last one. Don't you think so?" Ri's hands worried the sides of his outer garment. "Yes, sir. It would Extrone pursed his lips. "It wouldn't have been very considerate of you Extrone's lip twisted in wry amusement. "If I had waited until it was "Of course," Extrone said. "But you should have spoken to me about it, his hand in a broad gesture, "the highest as well as the lowest slave, know me and love me. I know your intentions were the best." Ri squirmed, his face pale. "We do indeed love you, sir." "Yes, sir. Know you and love you, sir," Ri said. Mia glanced suspiciously around him at the shadows. "You begin to understand a lot of things, after seeing him." Ri picked nervously at the cover of his sleeping bag. "It makes you think," Mia added. He twitched. "I'm afraid. I'm afraid he'll.... Listen, we'll talk. When we get back to civilization. You, me, the bearers. About him. He can't let that happen. He'll kill us first." Ri looked up at the moon, shivering. "No. We have friends. We have influence. He couldn't just like that—" "He could say it was an accident." "No," Ri said stubbornly. "He can say anything," Mia insisted. "He can make people believe anything. Whatever he says. There's no way to check on it." "No," Ri said. "Even if we tried to tell them, they wouldn't listen. Everybody would know want to overthrow him!" Ri's teeth, suddenly, were chattering. "That's another lie," Mia continued. "That he protects the people from the Army. That's a lie. I don't believe they were him, don't you see?" Ri whined nervously. him in power when the people were in rebellion against military rule." Ri swallowed. "We couldn't make the people believe that." You'll see. Because I think the Army is getting ready to invade the alien system!" "The people won't support them," Ri answered woodenly. " Think. If he tells them to, they will. They trust him."

"It was to keep the natural economic balance." "You know that's not right." Ri lay down on his bed roll. "Don't talk about it. It's not good to talk like this. I don't even want to listen." "When the invasion starts, he'll have to command Ri swallowed sickly. "Remember our guide? To keep our hunting territory a secret?" Ri shuddered. "That's different. Don't you see? This is not at all like that." Extrone laughed harshly. "It's 'sir' whenever you contradict me?" Extrone carried the only weapon, slung easily over his shoulder, a "Extrone. Eh?... Oh, you got their ship. Well, why in hell bother "I don't want to listen to your gabbling when I'm hunting!" Extrone Extrone squinted up at the sun "Look," Extrone said. "If that's the case, why do we bother tracking the—ah—the bait." Ri twisted at the grass shoot, broke it off, worried and unhappy. "What's he want to see me "I don't know," Lin said curtly.
