" 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.

"If I have to, that's just what I plan," he replied. "However, there are
women in that camp. Nude women. And, frankly, I don't hanker after any
of the kind of publicity which undoubtedly would result from such a
search. So I want to avoid it if I can."

"Then what--"

"I'll go in alone! That's it!" Major Coggleston straightened, suddenly
decisive. "Sergeant, go back to the laboratory and round up all but a
skeleton guard. Bring them back to the nudist camp and surround it.
Don't let anyone escape! Do you understand me?"

"Yes, sir. I am to surround the nudist camp with our men as soon as
possible, leaving only a skeleton guard on the laboratory."

"Right. On your way."

The sergeant strode out, and a moment later the car in the driveway
roared to life. And back in the house, the major drew a deep breath.

"Well, I'm off!" he snapped. "Wish me luck!"

"You?" Major Coggleston stared. "What for?"

Henry started in indignation at the other's tone. He drew himself to his

Officer: how are you going to identify the man who bought my glasses if
I'm not along?"

The major considered this. Then, at last:

"All right. I guess you'll have to come."

"Then so do I."

It was Professor Paulsen.

"Joe, there's no need to talk like that," Major Ray Coggleston began.

"If Henry goes, I go," the savant reiterated stubbornly. "He gets in
enough jams with me around to look after him. Lord knows what he'd do if
he got away from me."

And so it was, ten minutes later, that the three appeared at the main
gate of the Sunset Glow Nudist Colony: Let Old Sol Bring You Health.
From within the fenced enclosure came the glow of firelight and the
sound of festivities. A burly short-clad gateman was on duty.

"Well?" he demanded.

Major Coggleston displayed his credentials.

"You've got a man in there whom we suspect of being a spy," he
explained. "We've got to come in and investigate."

The gateman hesitated and chewed his lower lip.

"O.K.," he said finally. "Dit
