he thought they would actually find what they were looking for. Queazy discharged their tremendous inertia into the motive-tubes in such a manner that the big, powerful ship was moving at the same rate as the asteroid below—47.05 miles per second. He came slogging back excitedly, put his eyes to the eyepiece. He gasped, and his big body shook with joyful ejaculations. "She checks down to the last dimension," Bob chortled, working with "Whee! Mr. Andrew S. Burnside, you owe us five hundred and fifty thousand dollars!" Queazy straightened. A slow, likeable smile wreathed his tanned face. to the winds and it fell gently to the deck-plates. While Queazy—so neither Bob nor Queazy would have thought of sending an answering Now that he and Queazy had found the asteroid, they were desperate to Saylor made no pretense of being scrupulous. Neither he nor Queazy had the opportunity to observe the pointer any Queazy made a gulping sound and slowly straightened. He automatically He and Queazy caught up with her on the side of the asteroid they Queazy said simply, "That's right, miss. We're in a spot. I assure you death! So that's that." Bob recognized finality when he saw it. "Come on, Queazy," he said fuming. "Let this brat have her way. But if I ever run across her without a space-suit on I'm going to give her the licking of her life, right where it'll do the most good!" Oh! " Bob Parker's stomach caved in. A few hundred feet away, floating surveying the three who faced them. think of this situation Billy?" "It's obvious," drawled Billy Saylor, rocking back and forth on his heels, "that Bob Parker and company have double-crossed us. We'll have to take steps." laughter. Bob Parker's gorge rose. "Scram," he said coldly. "We've got an Queazy. Queazy got the idea, urged his immense body into motion. He before the flickering points of light in his brain subsided to complete What had happened to Queazy he didn't know. He felt so horribly sick, no asteroid, no girl, no Queazy. He was alone in the vastness of space. Alone in a space-suit. "Queazy!" he whispered. "Queazy! I'm running out of air!" There was no answer from Queazy. With sick eyes, Bob studied the oxygen indicator. There was only five pounds pressure. Five pounds! That meant he had been floating around out here—how long? Days at least—maybe weeks! It was evident that somebody had given him a dose of spastic rays, enough to screw up every muscle in his body to the snapping point, putting him in such a condition of suspended animation that his oxygen needs were small. He closed his eyes, trying to fight against panic. He was glad he couldn't see any part of his body. He was probably scrawny. And he was hungry! "I'll starve," he thought. "Or suffocate to death first!" He couldn't keep himself from taking in great gulps of air. Minutes, then hours passed. He was breathing abnormally, and there wasn't enough air in the first place. He pleaded continually for Queazy, hoping that somehow Queazy could help, when probably Queazy was in the same condition. He ripped out wild curses directed at the Saylor brothers. Murderers, both of them! Up until this time, he had merely thought of them as business rivals. If he ever got out of this— He groaned. He never would get out of it! After another hour, he was gasping weakly, and yellow spots danced in his eyes. He called Queazy's name once more, knowing that was the last time he would have strength to call it. He did not lose consciousness. He heard voices, Queazy's and the Queazy was bending over him, his anxiety clearing away from his us, and when she woke up she was on a slow orbit around her ship. her enough reaction to reach the ship. She got inside and used the Bob saw the girl now, standing a little behind Queazy, looking down at Bob came slowly to his feet, and matched Queazy's slowly growing anger. "Say that again?" he snapped. "This is some kind of dirty trick you and your grandfather cooked up?" If you knew my grandfather, you'd know how absolutely impossible it find the asteroid in time they wouldn't be able only a few hundred feet away. He swung around, looked at Queazy. "How long were we floating around out there?" "Three weeks, according to the chronometer. The Saylor boys gave us a stiff shot." " determination. "Miss, pardon me if I say that this deal you and your granddad cooked up is plain screwy! With us on the butt end. But I'm going to put this to you plainly. We can catch up with the Saylor long, spiraling orbit. We can go direct and probably catch up with them Queazy looked from one to another of them. He waved his hand scornfully at Bob. "You're plain nuts," he complained. "How do you propose to go about convincing the Saylor brothers they ought to let us have the Starre. "He's always pulling me up short when I go off half-cocked. All I know is, that maybe we'll get a good idea as we go along. In the meantime, Starre—ahem—none of us has eaten in three weeks...?" Starre got the idea. She smiled dazzlingly and vanished toward the "Even I know that isn't the control to the Holloway vacuum-feeder, go from zero speed to our top speed of two thousand miles a second just like that!" He snapped his fingers. "No acceleration effects. This type of ship, have to marry him?" Her eyes filled with tears. "I have to live up to the bargain." "And ruin your whole life," he ground out. Suddenly, he turned back to the control board, quartered the vision plate. He pointed savagely to Starre's blue eyes followed the long cable back to where it was got out of the chair so fast. "Can you imagine it! A yo-yo!" He disappeared from the room. "Queazy!" he shouted. " Queazy, I've got It was Queazy who got into his space-suit and did the welding job, Parker practiced and experimented for three hours with this yo-yo of cosmic dimensions, while Starre and Queazy stood over him bursting into strange, delighted squeals of laughter whenever the yo-yo reached the end of its double cable and started rolling back up to the ship. Queazy snapped his fingers. "It'll work!" His gray eyes showed satisfaction. "Now, if only the Saylor brothers are where we calculated!" They weren't where Bob and Queazy had calculated, as they had naked-eye distance of the Saylor brothers' ship. Below, Earth was Queazy's big hand gripped his shoulder. "Go to it, Bob!" again. All this had happened in such a short space of time that the Saylor Queazy was across the room in two running strides. He threw in the telaudio and almost immediately, Wally Saylor's big body built up in the plate. Wally Saylor's face was quivering with wrath. "What do you damned fools think you're trying to do?" he roared. He snapped the hauler into its mile-a-second speed again, stopped it at zero. And the "yo-yo" went on its lone, destructive sortie. For a fraction of a second Wally Saylor exhibited the countenance of a doomed man. In the telaudio plate, he whirled, and diminished in size with a strangled yell. heavily, then rebounded and came spinning back with perfect, sparkling precision. And even before it snugged itself into its berth, it was apparent that the Saylor brothers had given up. Like a wounded terrier, their ship shook itself free of the asteroid, hung in black space for
