Rick identified it easily. It was a tiny transistor, an integral part of modern electronic apparatus.

Mac took it in his big fingers. "Thanks. I must have stuck it in my pocket absent-mindedly while we were repairing the equipment."

"Where do you go when you're on a field radar job?" Rick asked. "Just tell me to mind my own business, if I get into anything classified."

"There's no classification on what we do," Pancho Kelly said. "Only the results. We go to Careless Mesa. Everyone knows that."

The boys let the conversation lag and ordered dinner. They didn't want to seem too inquisitive. Constant questions would only make Mac and Pancho suspicious.

Later, as they rode through the star-studded night in their jeep, Scotty suddenly asked, "What do you think of Big Mac and Pancho?"

Rick shrugged. He knew what had prompted Scotty's question. He had the same feeling himself. "They're friendly enough, but I think it's an act. What I mean, is ..."

"That they haven't any real interest in being friendly, they're just cordial for the sake of appearances," Scotty concluded.

"On the nose, pal. I get the feeling they could switch from casual conversation to mayhem without batting an eye."

Scotty thought it over for a moment. "Mac's the driving force of the pair, but I'd say they're equally tough. I'd guess Pancho is a combination of Irish and Mexican, both from his looks and his name."
