"How?" Henry's goatee jerked with contempt. "How would I know anyone was there? I saw him. He was right behind the blonde with the cute—"
"Henry!"
"Oh, all right. Anyhow, he was right behind a blonde girl. I saw him when I looked through my glasses while I was showing Joseph how to use them."

"I'll be damned if I know what to do!" he exploded. "I've got to find that spy. But I can hardly seize a whole nudist camp just because a red-headed man bought a pair of binoculars."
"Couldn't you ask that all red-headed men be brought to the gate?" suggested Professor Paulsen.
"No." The officer shook his head. "If the man we want is there, that would tip him off."
"Excuse me, sir," broke in the sergeant who accompanied Major Coggleston, "but why not just search the whole place with the men you've got detailed for guard duty? It wouldn't be much of a job."
The major nodded.
