“So you see, I did not actually share lodging with him.”

“Yes, I was aware of that. But why are you the only one who knows where to find him?”

“I’m not. Brad knows. Other members of the project know, though they never talk about it.”

This time her flush was frustration, and he felt the angry flexure in the muscle of her leg. She doesn’t like to be balked.

“Brad told me you were the only one who could summon him!”

“It’s an — arrangement we have.”

“Brad knows where Schön is, but won’t go for him himself? That doesn’t sound like—”

The journey by rail was over, no tunnel of love. “Brad can’t go for him himself. I guess you could call me an intermediary, or maybe a personal secretary. An answering service: that’s closest Schön simply won’t come out for anyone unless I handle it. He doesn’t involve himself with anything that isn’t sufficiently challenging.”

“An alien destroyer that has our whole exploratory thrust stymied — isn’t that enough?”

So she knew what Brad had told him. “I’m not sure. Schön is a genius, you see.”

“So Brad has informed me, many times. An IQ that can’t be measured, and completely amoral. But surely this is cause!”

“That’s what I’m here to decide.”

They arrived at the common room: a large compartment of almost standard Earth-gravity, with easy chairs and several games tables. Ivo wondered what billiards or table-tennis would be like in partial gravity. Beside the entrance were several hanging frameworks: games ladders with removable panels. On each panel was a printed name.

“Who’s Blank?” he asked, reading the top entry of the first.

“That’s a real name,” she said. “Fred Blank, one of the maintenance men. He’s the table-tennis champion. I don’t really think they should — I mean, this room is for the scientists, the PhD’s. To relax in.”

“The maintenance men aren’t supposed to relax?”

She looked a little flustered. “There’s Fred now, reading that magazine.”

It was a Negro in overalls and unkempt hair. Beside him sat a Caucasian scientist, portly and cheerful. Both looked hot; evidently they had just finished playing a game. It seemed to Ivo that Afra was the only one disturbed, and that told him something about both her and the other personnel of this station. The scientists respected skill wherever they found it; Afra had other definitions. The portly white for the moment probably envied Blank his facility with the paddle, without being concerned with such irrelevancies as education.

In the center of the room stood a pedestal bearing a shining statuette mounted at eye level. Ivo paused next to contemplate this honored edifice. It was a toy steam-shovel, of storybook design, with a handsome little scoop. The cab was shingled like the top of a country cottage, with a delicately sagging peaked roof and a bright half-moon on the door. Within the jawed shovel was a ball like a marble, and so fine was its artistry that he could see the accurate outline of the continent of North America etched upon the surface of that little globe.

The pedestal bore the ornate letters S D P S. “What does it mean?”

Afra looked embarrassed again. “Brad calls it the ‘Platinum Plated Privy,’ ” she murmured, quiet though no one else was close. “It really is. Platinum plated, I mean. He — designed it, and the shop produced it. The men seem to appreciate it.”

“But those letters. S D P S. They can’t stand for—”

She colored slightly, and he liked her for that, sensing a common conservatism though their viewpoints in other respects differed strongly. “You’ll have to ask him.” Then she shifted ground. “Here we are talking about unimportant things and ignoring you. Where do you come from, Ivo? That is, where did you settle after you left your project?”

“I’ve been walking around the state of Georgia, mostly. All of us who participated in the project were provided with a guaranteed income, at least until we got established. It isn’t much, but I don’t need much.”

“That’s very interesting. I was born in Macon, you know. Georgia is my home state.”

Macon! “I didn’t know.” But somehow he had known.

“But what interested you about that state? Do you know someone there?”

“Something like that.” How could he explain ten years of seeming idleness, retracing the various routes of a native son?

She didn’t press him. “I should show you the infirmary, too; Brad did mention that. I suppose he wants you to be able to describe it accurately to Schön.”

They traveled on. Ivo wondered what was supposed to be so important about the infirmary, but was content to wait upon her explanation. He was learning more about her every moment, and positive or negative, he was eager for the information.

“One thing I don’t understand,” Afra fretted, “is why Schön was in that other project. He should have been with Brad.”

“He was hiding. Do you know the parable about the good fish?”

“The good fish?” Her brow furrowed prettily.

“The good fish that the fisherman caught in the net and gathered into vessels, while the bad were cast away. Matthew XIII:48.”

“Oh. Yes, of course. What is the relevance?”

“If you were one of the fish in that lake, which kind would you want to be?”

“A good one, naturally. The whole point of the parable is that the good people shall find favor with God, while the bad ones will perish.”

“But what happens, literally, to the good fish?”

“Why, they are taken to the market and—” She paused. “Well, at least they aren’t wasted.”

“While the bad fish continue to swim around the lake, just as they always did, because no fisherman wants them. I’d rather be one of them.”

“I suppose so, if you take it that way. But what has that to do with—” She broke off again. “What did they do with the geniuses in Brad’s project?”

“Well, I wasn’t involved in that. But I would guess Schön wanted to live his own life, unsupervised by the experimenters. So he hid where they would never find him. A bad fish.”

“Brad had no trouble. I know he didn’t fool them any more than he fooled me. He’s a lot more intelligent than he says he is.”

Ivo remembered that Brad had represented himself to her as IQ 160. “That so? He always seemed pretty regular to me.”

“He’s like that. He gets along with anybody, and you really have to get to know him before you realize how deep and clever he is. He was the big success of the project — but of course you know that. Even if he does try to claim he’s stupid compared to Schön. I used to think he made Schön up, just to amuse me; but since this crisis—”

“Yeah. That’s the way it was with me too, in a way. But now I sort of have to believe in Schön, much as I might prefer to forget all about him, or there isn’t much point in hanging around.”

She smiled. “I’d tell you not to feel sorry for yourself, if I didn’t so often feel the same way. Nobody likes to feel stupid, but around Brad—”

“Yeah,” he said again.

They entered the infirmary. It carried the usual aseptic odors, the normal aura of spotless depression. “These are the — five,” she said, bringing him to a row of seated men. “Dr. Johnson, Dr. Smith, Dr. Sung, Dr. Mbsleuti and Mr. Holt. All most respected astronomers and cryptologists.”

“Johnson? Holt? Sung? I’ve heard those names before.”

“Yes, Brad would have mentioned them, if you weren’t already familiar with their reputations. The significant planets they discovered were named after them. Did Brad explain — ?”

“He showed me some planets. I didn’t realize — well, never mind. I know now.”

He looked at the seated men. Dr. Johnson was a saintly-looking man of perhaps sixty, with iron hair and brows and deep lines of character about the eves. His gaze was direct and compelling, but fixed, as though he were concentrating on some transcendent intangible.
