 What is Ledman's relation to UranCo?
THE HUNTED HEROES By ROBERT SILVERBERG The planet itself was tough enough—barren, desolate, forbidding; enough to stop the most adventurous and dedicated. But they had to run head-on against a mad genius who had a motto: Death to all Terrans! I reached over and turned up the pressure on her oxymask to make things a little easier for her. Nothing but what had stopped us could stop a sandcat: sand in the delicate mechanism of the atomic engine. But no; she blamed it all on me somehow: So we were out walking on the spongy sand of the Martian desert. "Maybe there isn't any uranium in this sector at all. When Val's tired and overwrought there's no sense in arguing with her. Behind us somewhere was the comfort of the Dome, ahead nothing but the mazes and gullies of this dead world. He was a cripple in a wheelchair—helpless as a rattlesnake. Remember—we're doing this for Earth. And UranCo's pay is stinking." She had been just as much inflamed by the idea of coming to Mars to help in the search for uranium as I was. We knew the pay was poor, but we had felt it a sort of obligation, something we could do as individuals to keep the industries of radioactives-starved Earth going. And we'd always had a roving foot, both of us. No, we had decided together to come to Mars—the way we decided together on everything. The geiger kept up a fairly steady click-pattern, but never broke into that sudden explosive tumult that meant we had found pay-dirt. I stopped, slipped out of the geiger harness, and lowered myself ponderously to the ground. "No, baby," I said, putting out a hand and taking hers. She slid down beside me, curled up, and in a moment she was fast asleep, sprawled out on the sands. Maybe we shouldn't have come to Mars after all. I watched her, sleeping peacefully, a wayward lock of her soft blonde hair trailing 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 struggle that was Mars. It's because we wanted to keep what we had. The Geig Corps preferred married couples, working in teams. We had no ties on Earth that couldn't be broken without much difficulty. The wind blasted a mass of sand into my face, and I felt it tinkle against the oxymask.
