"Want an asteroid in your backyard? We supply cheap. Trouble also handled without charge." Interplanetary Hauling Company. (ADVT.) [Transcriber's Note: This etext was produced from Planet Stories Summer 1945. she's made of tungsten, iron, quartz crystals, and cinnabar! But there couldn't be two asteroids of that shape anywhere else in the Belt, so asteroid." "Have it your way," Bob Parker sang, happily. He threw the ethergram called because his full name was Quentin Zuyler—dropped the ship straight down to the smooth surface of the asteroid, and clamped it tight with magnetic grapples, Bob flung open the lazarette, brought In the ship, the ethergram from Andrew S. Burnside, of Philadelphia, one of the richest men in the world, still lay on the deck-plates. It was addressed to: Mr. Robert Parker, President Interplanetary Hauling &amp Moving Co., 777 Main Street, Satterfield City, Fontanaland, Mars. The ethergram read: that yes I would like an asteroid in my back yard. Must meet following pay $5.00 per ton. Bob Parker had received that ethergram three weeks ago. And if The Interplanetary Hauling &amp Moving Co., hadn't been about to go on the there was such a rigidly specified asteroid, their financial worries would be over. That they had actually discovered the asteroid, using asteroids in the asteroid belt, and they had been out in space only The "asteroid in your back yard" idea had been Bob Parker's originally. rich man who had decided to hold a wedding on top of an asteroid. Unfortunately, other interplanetary moving companies had cashed in on 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 Neither he nor Queazy had the opportunity to observe the pointer any further. A cold, completely disagreeable feminine voice said, "May I ask what you interlopers are doing on my asteroid?" asteroid "below." "I said," remarked the girl, "that you should scram off of my asteroid. And quit poking around at it with that spectroscope. I've already taken a reading. Cinnabar, iron ore, quartz crystals, tungsten. Goodbye." Her expression darkened as she saw the completely instinctive way he was looking at her and her radioed-voice rapped out, "Now you two boys go and play somewhere else! Else I'll let the Interplanetary Commission know you've infringed the law. G'bye!" She turned and disappeared. " He and Queazy caught up with her on the side of the asteroid they hadn't yet examined. It was a rough plane, completing the rigid and it was three times as big as her gloved hand. "I understand conditions better than you do," she said. "You want to move this asteroid from its orbit and haul it back to Earth. Unfortunately, this is my home, by common law. Come back in a month. I don't expect to be here then." an asteroid that doesn't mean anything to you one way or another. But to us—to me and Queazy here—it means our business. We got an order for this asteroid. Some screwball millionaire wants it for a backyard wedding see? We get five hundred and fifty thousand dollars for it! If we don't take this asteroid to Earth before June 2, we go back to Satterfield City and work the rest of our lives in the glass factories. Don't we, Queazy?" 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." double-crossed. Those boys are after this asteroid too, and they won't hesitate to pull any rough stuff. We're in this together, understand? We got to back each other up." "It's—it's very important that this—this asteroid stay right where it sparks crackled between the hull and the asteroid as the magnetic find out who I am and what I've done. I'm Starre Lowenthal—Andrew S. asteroid like this. But I did, long before he ordered it from you—or nerves. So I decided to trick him and I came out to the asteroid belt 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, find the asteroid in time they wouldn't be able to get it back to Earth, I came out here and decided to live here. Asteroids up to a certain size belong to whoever happens to be on them, by common law.... So I had everything figured out—except," she added the asteroid was delivered, so he gave the order to several companies." Bob swore under his breath. He went reeling across to a port, and was gratified to see his and Queazy's big interplanetary hauler floating 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 ours both travel on the HH drive—inertia-less. But the asteroid has 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 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 later. Okay?" asteroid back? Remember, commercial ships aren't allowed to carry Starre. "He's always pulling me up short when I go off half-cocked. All 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 "Right," he said unsteadily. "Anyway, Starre, as I was saying, this shake. He took her hand. "Starre," he said desperately, "I've got to have to marry him?" Her eyes filled with tears. "I have to live up to the bargain." "There's your ship, Starre." He jabbed his finger at it. "I've got a Starre's blue eyes followed the long cable back to where it was cosmic dimensions, while Starre and Queazy stood over him bursting into discovered the next day. They had expected to pick up the asteroid the still bigger asteroid—inside the Moon's orbit! A mere two hundred the asteroid was several times as massive as the ship which was towing Starre was chortling with glee. Queazy whispered, "Attaboy, Bob! This "I'll inform the Interplanetary Commission!" screamed Saylor. " If you release the asteroid."
