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. "Ditch your clothes in the brush, over there."

"Ditch our clothes!"

"Sure." The gateman nodded determinedly. "You didn't think you could come in the way you are, did you?"

"But we represent the United States Government—"

"I don't give a damn who you represent." The gateman was adamant. "If you want to enter Sunset Glow, you'll do it in bare skin or not at all."
