Then the moderator questioned Malcomb, while Gavir nervously awaited the moment when his thoughts would be transmitted to millions Gavir thought. Back behind the Preserve Barrier that killed you instantly if you stepped too close to it? Back to the constant fear of vengeance. Back to that world of hopeless fear and hatred? I never want to go ." He heaved himself up from the divan, and, feet planted wide apart, threw back his head and began to howl. startled sidestep saved him from the neck-breaking snap of the great jaws. for one cast of the blade. It had to be done at once. It had to be perfect. If it failed, the knife would be lost and the drock would with it again and again into the gray twitching belly. Colorless blood ran out over the hard, tightly-stretched skin. The drock fell, gave a last convulsion, and lay still. The hunter He began shouting even before Gavir removed his headset. "What kind of a fool are you? Before you started that song, you dreamed things nerve-wracking business. If it weren't for Ethical Conditioning, I Malcomb smiled. "Ethical Conditioning Keeps Society from Fissioning." Malcomb, "Can we go to a bookstore tonight?" "Tomorrow. I'm taking you to your hotel and then I'm going back to my apartment. We both need sleep. And don't forget, you've been warned In a pitifully few days he would be back in the Preserve, back with the fear of MDC, with hunger and the hopeless desire to find and kill only hope to find an alternative to the short, fear-ridden, impoverished life he foresaw for himself. and lowered him through the city's multiple levels.... And, as has always happened to outlanders in cities, he became lost. He was in a quarter where furtive red and violet lights danced in the "But you did not tell me that Earthmen might try to kill me. You have told me that Earthmen are good and peace-loving, that there have been no acts of violence on Earth for many decades. You have told me that only the MDC men are exceptions, because they are living off Earth, and this somehow makes them different." "Well, those people you ran into are another exception." "Why?" "You know about the Regeneration and Rejuvenation treatment we have here on Earth. A variation of it was given you to acclimate you to Earth's gravity and atmosphere. Well, since the R&amp R treatment was developed, we Earthmen have a life-expectancy of about one hundred fifty years. Those people who attacked you were Century-Plus. They are over a hundred years old, but as healthy, physically, as ever." "What is wrong with them?" "They seem to have outgrown their Ethical Conditioning. They live wildly. Violently. It's a problem without precedent, and we don't know what to do with them. The fact is, Senile Delinquency is our number one problem." "Why not punish them?" said Gavir. "They're too powerful. They are often people who've pursued successful careers and acquired a good deal of property and position. And there are getting to be more of them all the time. But come on. You and I gotten into trouble because of his thoughts about MDC. "If you let that boy go back to Mars I'll never dream a Global program like being mad!" "Keep him on Earth." Hoppy Davery pressed a button in the control panel on his divan, and spot on next week's Farfel Flisket Show. If he gets the right response, we talk about a contract. Okay?" Malcomb said, "His visa expires—" "We'll take care of his visa." something they go for. Undoubtedly because you're—forgive me—such a complete barbarian. That's what they're all trying to be." "Spare me another lecture on Senile Delinquency, Our Number One ." "It's part of a fertility rite," Malcomb explained. "Great! Give the Senile Delinquents another workout. It's not quite ethical, but its good for us. But for heaven's sake, Blue Boy, keep your mind off MDC!" mind to his audience. A jubilant Hoppy Davery called him at his hotel next morning. "Best response I've ever seen! The Century-Plussers have been rioting and throwing mass orgies ever since you sang. But they take time out to call us up and beg for more. I've got a sponsor and a two-year congratulated himself. He had learned emotional control from the battered face. "I'm told you got talent. Okay, but a Bluie is a Bluie. I'll pay you because a Bluie on Dreamvision is good publicity for MDC products. But one slip like on your first 'cast and you go back to the Preserve." "Damn right. That Ethical Conditioning slop doesn't work on me. I've lived too long on the frontier. And I know Bluies." lady, we'd deport you so fast your tail would burn. And God help the Bluie!" You're back in civilization where we do what we damned well please." Spurling laughed. "I've heard about you Century-Plussers. You're all sick." "You can't claim any monopoly on mental health. Not with that concentration camp you run on Mars. Coming, Gavir?" strolled out. "You screwball Senile Delinquent," Spurling yelled after Sylvie, "you oughtta be locked up!" Century-Plussers. Gavir told her about the attack, and she laughed. "It won't happen again. You're a hero to the Senile Delinquents now. you are? Why—and how—have you broken away from Ethical Conditioning?" She said, "I didn't do it deliberately. When I reached the age of about a hundred it stopped working for me. I suddenly wanted to do what I I wanted to do. It was Ethical Conditioning or nothing, so I picked "How do you chase nothing?" She set fire to a white tube. "This, for instance. They used to do it before they found out it caused cancer. Now there's no more cancer, but even if there were, I'd still smoke. That's the attitude I have. You try things. You live in the past, if you're inclined, adopt the costumes and manners of some more colorful time. You try ridiculous things, disgusting things, vicious things. You know they're all nothing, but you have to do something, so you go on doing nothing, elaborately and violently." Century-Plussers. Male Century-Plussers by the millions adopted blue doublets and blue kilts in honor of their hero. Blue-dyed hair was now de rigueur enemies, false friends and callous leaders. It was a protest against sufferings that could neither be borne nor prevented. At the climax of deserves, or I will give you death. It will be a personal thing between you and me. I will besprinkle you with corrosive acids I will burn out your eyes I will—" Hoppy cut the voice off. Gavir saw that he was sweating. "There were I cannot always control the pictures I make. These images come into my mind even though they have nothing to do with me." Hoppy shook his head. "That's because you haven't had Ethical Conditioning. We don't have this trouble with our other performers. the Senile Delinquents were giving a party for him in the Pandemonium Room. The only prominent person missing, as Sylvie remarked after surveying the crowd, was the Hat Rat. They wondered about it, but no your salary and keep you here on Earth, and this is what I get for it. "The enemy!" the Hat Rat shouted. The shotgun exploded. red caved-in place in Spurling's chest. Spurling's body sagged to the floor and lay there face up, eyes open. The Senile Delinquents of Lucifer Grotto leaned forward to grin at the tattered body.
