when a man gets his feet down on gravity again. This one didn't. But it might have worked out, at that. It was just Garrity's luck that he signed on the Brooklyn. The Brooklyn carried ore from Serco to Terra, and Terran machinery back to Serco, a regular, steady run. When I bumped into Garrity in the hiring hall, he told me he'd just signed on her, and I told him I had, too. Naturally, I asked him how the Garrity old-age-insurance system was working out. "Well," he confessed, "I'm not married yet. But I've got a likely girl here in Terra City. All I've got to do is ask her. Now if I can line one up in Serco—" "In Serco?" I turned a little pale, I think. "Listen, Garrity, have you ever been in Serco?" "No. Why? Aren't they humanoids?" "Oh, sure." I was trying to think just how you'd describe Serco and its peculiar people. "Only different." "How're they different?" Looking at that stubborn mug of his, I knew I wasn't going to be able to explain this in a million years. It was just no use. Garrity had everything all figured out. But I took one try. "They've never been much of a mechanical culture; they buy all their stuff from outside, in exchange for ore and timber. But they're one of the oldest civilizations in the Galaxy. They've spent a million years learning about minds and thoughts, all that philosophy sort of thing. I don't mean they aren't perfectly all right. They're human, but they know a lot. It wouldn't pay to fool around with them." Garrity laughed. "Maybe they might read my mind?" I knew it was no use. I just shrugged, bought Garrity a beer to celebrate, and we headed for the spaceport. No, the Sercoans don't read minds. At least, I don't think they do, though there are times when they're that clever at adding you up that you'd think they were looking at your thoughts. Garrity didn't get caught that way. He got caught because he couldn't keep from telling the rest of us about his great idea. One of the navigators, a man named Lane, was the one who told Katha about it.
