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 yo
