human way of thinking.
But that was the gist of it. The man he had seen in that new building at Carlson Spacecraft was no ordinary human being.
That, however, didn’t bother Karnes half so much as the gray globe the man had disappeared into after he had been shot at. And Karnes knew, now, that the shots probably hadn’t missed.
The globe was one of two things. And the intruder had been one of two groups.
(A) One of the Surveyors of Ancient Earth, in which case the globe had been a—well, a time machine. Or
(B) A student, in which case the machine was a type of spacecraft.
The question was: Which?
If it were (A), then he and the world around him were real, living, working out their own destinies toward the end point represented by the man in the gray globe.
But if it were (B)—
Then this was the Shrine, and he and all the rest of Earth were nothing but glorified textbooks!
And there would come crises on the Shrine, duplicates of the crises on old Earth. Except that they wouldn’t be permitted to happen. The poor ignorant people on the Shrine had to be coddled, like the children they were. Damn!
Karnes crumpled the sheets of paper in his hands, twisting them savagely. Then he methodically tore them into bits.

When the first dawnlight touched the sea, Karnes was watching it out the east window. It had been twenty-four hours since he had seen the superman walk into his gray globe and vanish.
All night, he had been searching his brain for some clue that would tell him which of the two choices he should believe in. And he couldn’t bring himself to believe in either.
Once he had thought: Why do I believe, then, what the impressor said? Why not just forget it?
But that didn’t help. He did believe it. That alien instrument had impressed his mind, not only with the facts themselves, but with an absolute faith that they were facts. There was no room for doubt; the knowledge imparted to his mind was true, and he knew it.
For a time, he had been comforted by the thought that the gray globe must be a time machine because of the way it had vanished. It was very comforting until he realized that travel to the stars and beyond didn’t necessarily mean a spaceship as he knew spaceships. Teleportation—
Now, with the dawn, Karnes knew there was only one thing he could do.
Somehow, somewhere, there would be other clues—clues a man who knew what to look for might find. The Galactics couldn’t be perfect, or they wouldn’t have let him get the mind impressor in his hands. Ergo, somewhere they would slip again.
Karnes knew he would spend the rest of his life looking for that one slip. He had to know the truth, one way or another.
Or he might not stay sane.

Lansberg picked him up at eight in a police copter. As they floated toward New York, Karnes’ mind settled itself into one cold purpose; a purpose that lay at the base of his brain, waiting.
Lansberg was saying: “—and one of Brittain’s men got the stuff last night. He hadn’t passed it on to Brittain himself yet this morning, but he very probably will have by the time we get there.
“We’ve rigged it up so that Brittain will have to pass it to his superior by tomorrow or it will be worthless. When he does, we’ll follow it right to the top.”
“If we’ve got every loophole plugged,” said Karnes, “we ought to take them easy.”
“Brother, I hope so! It took us eight months to get Brittain all hot and bothered over the bait, and another two months to give it to him in a way that wouldn’t make him suspicious.
“It’s restricted material, of course, so that we can pin a subversive activities rap on them, at least, if not espionage. But we had to argue like hell to keep it restricted; the Spatial Commission was ready to release it, since it’s really relatively harmless.”
Karnes looked absently at the thin line of smoke wiggling from Lansberg’s cigarette.
“You know,” he said, “there are times when I wish this war would come right out in the open. Actually, we’ve been fighting the League for years, but we don’t admit it. There have been little disagreements and incidents until the devil won’t have it. But it’s still supposed to be a ‘worry war’.”
Lansberg shrugged. “It will get hot just as soon as the Eurasian League figures they are far enough along in spacecraft construction to get the Martian colonies if they win. Then they’ll try to smash us before we can retaliate; then, and not before.
“We can’t start it. Our only hope is that when they start, they’ll underestimate us. Say, what’s that you’re fooling with?”
The sudden change of subject startled Karnes for an instant. He looked at the mind impressor in his hands. He had been toying with it incessantly, hoping it would repeat its performance, or perhaps give additional information.
“This?” He covered quickly. “It’s a—a puzzle. One of those plastic puzzles.” Maybe it doesn’t work on the same person twice. If I can get George to fool around with it, he might hit the right combination again.
“Hmmm. How does it work?” George seemed interested.
Karnes handed it to him. “It has a couple of little sliding weights inside it. You have to turn the thing just right to unlock it, then it comes apart when you slide out a section of the surface. Try it.”
Lansberg took it, turned it this way and that, moving his hands over the surface. Karnes watched him for several minutes, but there didn’t seem to be any results.
Lansberg looked up from his labors. “I give up. I can’t even see where it’s supposed to come apart, and I can’t feel any weights sliding inside it. Show me how it works.”
Karnes thought fast. “Why do you think I was fiddling with it? I don’t know how it works. A friend of mine bet me a ten spot that I couldn’t figure out the combination.”
Lansberg looked back at the impressor in his hands. “Could he do it?”
“A snap. I watched him twice, and I still didn’t get it.”
“Mmm. Interesting.” George went back to work on the “puzzle.”
Just before they landed on the roof of the UN annex, Lansberg handed the impressor back to Karnes. It had obviously failed to do what either of them had hoped it would.
“It’s your baby,” Lansberg said, shaking his head. “All I have to say is it’s a hell of a way to earn ten bucks.”
Karnes grinned and dropped the thing back in his coat pocket.
By the time that evening had rolled around, Karnes was beginning to get just a little bored. He and Lansberg had been in and out of
