Scotty whistled. "They must be made of diamonds! Anyway, a quarter of a million is a lot of money, and even at two hundred bucks each the transistors would make quite a bundle. The Earthman would have to hide them, and then get them off the base. And I'll tell you one thing: If Big Mac stole them, he didn't take them off the base in his own car."

"How do you know?" Rick challenged.

"He's got a Porsche. There's about enough room in the luggage compartment for a spare handkerchief."

"I'll buy it." Another idea hit him. "But he has some other transportation, hasn't he? How about the radar unit he and Pancho run?"

Scotty snapped his fingers. "Now you're cooking! It's a panel truck, loaded with equipment, and they pull the radar antenna behind it on a trailer. There would be plenty of room in the truck. Only he doesn't take it into town, remember?"

"Would he need to? He could drop the transistors somewhere to be picked up later."

"Careless Mesa."

"What?"

"That's his station. Come on. Let's look at a map of the area." Scotty turned and led the way to their barracks.

One thing about the robbery was a major puzzle to Rick. He could see that a rocket shoot might provide the opportunity to commit the theft, and he could see how use of a radar van might get the stolen goods off the base. But the thief had carefully emptied cartons, leaving the cartons as camouflage. That took more time than any thief would have. He considered various ways in which it might have been done and rejected them all.
