"Because I was stupid enough to let you stay in my house, that's what for," Lester said bitterly. "Two days ago. Knocking on my door, hardly eight o'clock in the morning. They said there's a man missing, driving a truck, found the truck empty. Man from the Coast Guard station knows him, saw him picking up a couple of hitchhikers at a bridge someplace, recognized one of the hitchhikers. Said the hitchhiker'd been staying at my house. That's you, Howard. Don't lie; he described you. Pudgy, kind of a squinty look in the eyes, dressed like a bum—oh, it was you, all right."

"No, course not. She didn't see the picture, so how would she know? Would've said something if she had. Now come on, Howard, we've got to go to the police and—"

"Uncle Lester!"

The little man paused and looked at him suspiciously. But that was all right; Mooney began to feel confidence flow back into him. It wasn't all over yet, not by a long shot.

"Think, Uncle Lester! Please. Way back when you were a boy—anything like that?"

"Of course not!"

"You're sure? Because I'm warning you, Uncle Lester, you're going to have to take the strictest security check anybody ever took. You've stumbled onto something important. You'll have to prove you can be trusted or—well, I can't answer for the consequences. You see, this involves—" he looked around him furtively—"Schenectady Project."
