<passage>:
I The girl with the Slider egg glittering in her hair watched the bailiff lead Asa Graybar out of the courtroom. He recognized her as criminal. There was, perhaps, a crease of puzzlement in her brow, as if she had thought crimes were committed by shriveled, rat-faced types, and not by young biological engineers who still affected crewcuts. rap?" "Five or one." "Take the five," Jumpy advised. "Learn basket-weaving in a nice air-conditioned rehab clinic. A year on a changeling deal will seem a lot longer, even if you're lucky enough to live through it." Planet, with his physiology adapted to the environment of that wretched world, he could study the eggs under conditions no laboratory could duplicate. He might even be able to cause trouble for Hazeltyne. of altered shape before they signed a release. The requirement held whether or not the individual, like Asa, was already experienced. By the time humanity traveled to the stars, medical biology had made it possible to regenerate damaged or deficient organs of the body. "Four," answered the doctor. "Squiffs for New Arcady. Adapted for climbing the skycraper trees and with the arm structure modified into pseudo-wings or gliding. Then we one of them sounded like a woman's. But since women neither served on spaceships nor worked in the dome settlements on harsher worlds, he decided it was his imagination. He might have been dead cargo for all he learned about space travel. to die. There's nothing like a fresh one. And I'm not the first to go crazy over them. When I was reconverted and got home I had nine thousand dollars waiting for me. That'll buy a two-year-old egg that flashes maybe four times a day. So I stole a new one and got caught." Electrical instruments picked up static discharges from the egg, but swooping out of nowhere at you." "I've been meaning to ask you," Asa said. "How do you handle the Sliders?" Kershaw grinned. "First you try to catch it with a rocket. If you miss you start leaping for home. All this time you're broadcasting for help, you understand. learn the discomfort of double gravity. He was told he needed another When he finally awoke he felt well rested and very comfortable. But for a long time he was afraid to open his eyes. "Come on, Graybar," said a deep, booming voice. "Let's test our wings." It was not Kershaw's voice, but it had to be Kershaw. Asa opened his eyes. and muscle coordination was perfect. He found himself leaping as high as Kershaw's head. how to operate the radio he would carry and how to fire the pencil-slim rockets of this gun. Finally he was told to eat a few berries from a He leaped twenty feet into the air for a closer look. Gazing at him with repugnance, after witnessing the end of his session with Furston, were Harriet Hazeltyne and general manager Tom Dorr. The girl's presence merely puzzled Asa, but Dorr's being here worried him. Dorr had tried to get rid of him once and was now in an excellent position to make the riddance permanent. two were doing out here. "The girl will inherit this racket some day, won't she?" asked one of the others. "She wants to see what kind of suckers are making her rich." "Maybe that guy Dorr brought her along to show her what a big wheel he is," said one of the others. "Just hope he doesn't take over the and work that muck." Furston sent Graybar and Kershaw out together so that the veteran could not at all uncomfortable, and the dripping air caressed their skins like a summer breeze back on Earth. Tiny, slippery creatures skidded start shooting." At each leap along the trail they peered quickly around. They saw no before it was thrown away, to make sure it didn't conceal an egg. As he worked, Asa kept thinking what an inefficient system it was. Everything forward. Asa leaped with all his strength, sailing far out of the clearing. helicopter, Asa got under his companion's belly and lifted him by the waist. He hadn't realized before just how strong his new body was. Kershaw, as a muck man, would have weighed close to three hundred pounds on Earth, close to six hundred here. Dorr made no move to help, but the girl reached under Kershaw's cabin was crowded. Harriet. "You see, Miss Hazeltyne, I don't trust your friend. You might worried Asa. "Whatever you say, Graybar," Dorr said. He turned to the controls. In another minute the helicopter was in the sky. A round trip for the helicopter should have taken no more than twenty all along the way. A man had no chance of getting five miles with an egg by himself. He could leave the egg here, of course. Even so he There were no landmarks in this wilderness of bog to help him find his way. The workers were supposed to home in on radio signals, if they lost their bearings, but Dorr would deny him that help. Then he smiled in relief, for it was the helicopter, the blessed helicopter, coming in over the swamp. But what if it was Dorr, coming back alone to dispose of him without any witnesses? Asa leaped for the No machine-gun blast of rockets came from the helicopter. The big the landing skids caught against the Slider's body and the helicopter flipped forward on its nose, one of the rotor blades plunging deep into Asa leaped forward in consternation. Not only was his chance of safe passage back to the settlement wrecked, but now he would have the extra burden of taking care of the pilot. When he reached the nose of the helicopter he saw that the pilot, untangling herself from the controls to get up, was Harriet Hazeltyne. IV herself as she climbed out of the machine. "I guess not," she said. "But taking a fall in this gravity is no fun. From the way my face feels I ought to be getting a black eye pretty soon." "What happened?" "I made a fool of myself." She made a face back in the direction of the settlement. "Dorr wasn't going to come after you. He said anyone who talked back to him should try arguing with the Sliders." She looked up at the machine-gun on the helicopter. "They feed at night, you know. And they eat their own kind," she said. "The Slider you killed would draw them like ants to jam." Asa glanced around quickly to make sure no Sliders had already come. He eyed the helicopter with distaste at the thought of what a flimsy fort it would make. "Anyway," Harriet said, "I told him he couldn't just leave you here here was to check up for my father on the way he was running things and there seemed to be a lot wrong. So he told me very politely I could run things to suit myself and he walked off." She shrugged, as if to indicate that she had made a mess of things. "And you took the helicopter by yourself," Asa said, as if he could hardly believe it yet. "Oh, back on Earth I can make a helicopter do stunts. But I wasn't used to this gravity. I don't suppose you could make this machine stand up straight?" the plane. He pulled with all his strength at the rotor blade sunk in the mud, but the weight of the helicopter was upon it and the mud held it with a suction of its own. After a few minutes he had to give up. "We fight off the Sliders, then," she said, as matter of factly as if that problem was settled. "If it's any comfort, I know how to handle the machine-gun." "Nope. In this drizzle, at night, the Sliders would be on us before
