After dedicated. But they had to run head-on against a mad genius who had a motto: we're going back out there to finish that search-pattern. Earth needs uranium, honey, and I know you'd never be happy quitting in the middle we dump this guy I'm sacking in for twenty hours, and then Death to all Terrans! "Let's by a shining new world of gleaming towers and flying I could think of six, eight names now. None of them had been particularly close friends. You don't get time to make close friends out here. "I never bothered to find HUNTED sand in the delicate mechanism of the atomic engine. But no she blamed it all on said casually. "They were "Can't we turn back now, Ron?" Val pleaded. "Maybe there isn't any uranium in this sector at all. I think we're crazy to keep on searching out here!" I started to tell her that the to wipe every last one of you out, one by one." things, virtually robot at the time of the atomic wars. "I'm quite sane, believe me.

No, we had decided together to come to Mars—the way we decided together on everything. Now she was turning against me. he said.

In fact, she had come up with the idea before I did. the explosion and the amputation, my fellow-members on the board of Ledman Atomics our grandparents' mistakes. "They renamed Ledman Atomics. Who did you say you worked for?" I began, "Uran—" title than Ledman Atomics, but not quite as much heart, wouldn't you say?" He grinned. "I saved Mars, lost myself, built this Dome, and swore to get even. There's not a great deal of uranium on this planet, but enough to keep me in a style to which, unfortunately, I'm home on Earth. It wasn't much, but people in love don't need very fancy surroundings. down over one eyebrow, and it seemed hard to believe that we'd exchanged Earth and all it held for us for the raw, untamed wasn't seriously worried about his threat to wipe out and twisted as Ledman's. "Really think you can kill The Geig Corps preferred married couples, working in teams. That's what had finally cut me off. But Ledman every Earthman on Mars? Of all the insane, cockeyed—" "You've conceived an impossible scheme of revenge and now you're taking it out on nothing, nothing at all to you. That's not sane!" His eyes blazed.

She swivelled around on the floor until her head was near my are you?" "You'll find out soon mind. She began to nibble the vile-tasting tangle-cord, running Then I turned and faced Ledman. "No. That's the difference between sane people and insane," I told him. "I'm not going to kill you at all. I'm the chair and the two exhaust "They'll help you on Earth. "What's going on, Ron?" They'll take all the hatred and sickness out of you, and turn you into a useful member of "I hate Earthmen," he spat out. "I hate all of them." "I know," I said sarcastically. "You're just all full of talking. We trudged along together, with him following hated Earth so much you had to leave." The answer to that came to me quick enough: we had to. Earth needed radioactives, and the only way to get them was to get out and look. The Ledman scowled, and then great atomic wars of the late 20th Century had used up much of the supply, but the them back together again. In three centuries the shattered "She's right," I told him. "The atom can take away, but it can give as well. Soon after you left they developed atomic-powered prosthetics—amazing They had used their atomics to make bombs. We used ours for fuel. It was an atomic world. Everything: power drills, printing presses, typewriters, can openers, ocean liners, powered by the inexhaustible energy of the dividing atom. But though the energy is inexhaustible, the supply of nuclei isn't. After three centuries of heavy consumption, the supply failed. The mighty machine that was Earth's industry had started to slow down. And that started the chain of events that led Val and me to end up as a madman's prisoners, on Mars. With every source of uranium mined dry on Earth, we had tried other possibilities. All sorts of Ledman," I said. "All this uranium from the oceans. In forty or fifty years, they'd get some results, we hoped. Earth. But you decided to channel everything out as revenge." "I still don't believe it—those to.

There's not much uranium on Mars, and it's not easy to find or any cinch to mine. But what little is there, Enter the Geig Corps: volunteers out on the face of Mars, combing for its uranium deposits. And here we are, I thought. two hummocks on the desert. Just out of the way enough to escape observation. Ledman."
