shook with joyful ejaculations. "She checks down to the last dimension," Bob chortled, working with slide-rule and logarithm tables. "Now all we have to do is find out if neither Bob nor Queazy would have thought of sending an answering before this if he hadn't been lanky and tall while they were giants. Now that he and Queazy had found the asteroid, they were desperate to Bob Parker said, in astonishment, "Hell! There's something screwy about Bob started so badly that the spectroscope's settings were jarred and know you've infringed the law. G'bye!" She turned and disappeared. Bob awoke from his trance, shouted desperately, "Hey! Wait! You! expression did not change. She put her hands on the bulging hips of her space-suit. "Okay," she said. "Now I understand the conditions. Now we both understand each other. G'bye again. I'm staying here and—" she smiled sweetly "—it may interest you to know that if I let you have the asteroid you'll save your business, but I'll meet a fate worse than 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!" Bob Parker's stomach caved in. A few hundred feet away, floating We got to back each other up." The girl nodded dumbly. Suddenly she seemed to be frightened. "It's—it's very important that this—this asteroid stay right where it is," she said huskily. "What—what will they do?" Bob Parker didn't answer. The big ship had landed, and little blue There was no answer from Queazy. With sick eyes, Bob studied the 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!" The sudden rush of oxygen to his brain dizzied him. Then he was lying on a bunk, and gradually the world beyond his sick body focussed in his clearing eyes and he knew he was alive—and going to stay that way, for awhile anyway. "Thanks, Queazy," he said huskily. Queazy was bending over him, his anxiety clearing away from his suddenly brightening face. "Don't thank me," he whispered. "We'd have both been goners if it hadn't been for her. The Saylor brothers left her paralyzed like us, and when she woke up she was on a slow orbit around her ship. She unstrapped her holster and threw it away from her and it gave scattered us far and wide." Queazy's broad, normally good-humored face twisted blackly. "The so and so's didn't care if we lived or died." Bob saw the girl now, standing a little behind Queazy, looking down at him curiously, but unhappily. Her space-suit was off. She was wearing flower in her hair. Something in Bob's stomach caved in as his eyes widened on her. The girl said glumly, "I guess you men won't much care for me when you find out who I am and what I've done. I'm Starre Lowenthal—Andrew S. Burnside's granddaughter!" Bob came slowly to his feet, and matched Queazy's slowly growing anger. stubbornest old hoot-owl in this universe! He's always had his way, and when people stand in his way, that's just a challenge to him. He's been badgering me for years to marry Mac, and so has Mac—" "Who's Mac?" Queazy demanded. "My fiancé, I guess," she said helplessly. "He's one of my granddad's protégés. Granddad's always financing some likely young man and giving him a start in life. Mac has become pretty famous for his Mercurian water-colors—he's an artist. Well, I couldn't hold out any longer. If you knew my grandfather, you'd know how absolutely and picked out an asteroid that was shaped so a wedding could take place on it. I took the measurements and the composition, then I told my grandfather I'd marry Mac if the wedding was in the back yard on top of an asteroid with those measurements and made of iron ore, tungsten, and so forth. He agreed so fast he scared me, and just to make sure " Ouch! " Bob groaned. Then he looked at Starre Lowenthal with 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 a few hundred thousand miles this side of Earth. And we can have a fling at getting the asteroid back!" Her eyes sparkled. "You mean—" she cried. Then her attractive face "That's right," Bob said grimly. "We're in business. For us, it's a matter of survival. If the by-product of delivering the asteroid is your marriage—sorry! But until we do get the asteroid back, we three can work as a team if you're willing. We'll fight the other problem out at Bob. "You're plain nuts," he complained. "How do you propose to go 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 galley. Bob Parker was in love with Starre Lowenthal. He knew that after five days out, as the ship hurled itself at breakneck speed toward Earth probably that distracting emotion was the real reason he couldn't attach any significance to Starre's dumbbell-shaped ship, which trailed astern, attached by a long cable. Starre apparently knew he was in love with her, too, for on the fifth day Bob was teaching her the mechanics of operating the hauler, and she gently lifted his hand from a finger-switch. "Right," he said unsteadily. "Anyway, Starre, as I was saying, this at—Oh, hell!" Bob groaned, the serious glory of her eyes making him shake. He took her hand. "Starre," he said desperately, "I've got to tell you something—" She jerked her hand away. "No," she exclaimed in an almost frightened voice. "You can't tell me. There's—there's Mac," she finished, faltering. "The asteroid—" "You 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 How? " Starre's blue eyes followed the long cable back to where it was for Bob brought the hauler's speed down to zero—and Starre Lowenthal's little ship, possessing its own inertia, kept on moving! The excited cry came from Starre. But Bob swore. The dumbbell ship Bob sweated, having only fractions of seconds in which to maneuver ticklish work completely to nullify the "yo-yo's" speed. Bob used again. All this had happened in such a short space of time that the Saylor brothers must have had only a bare realization of what was going on. Starre was chortling with glee. Queazy whispered, "Attaboy, Bob! This you're alive," Bob snarled wrathfully. "And you won't be unless you release the asteroid."
