"Don't strain yourself," snorted Roger. But when Astro failed to reply in kind, the blond-haired cadet realized he was serious. "What is it?" he asked.
"Why, in the name of the moons of Mars, would Barret want to do the things he did to us?"
"Simple," said Roger, beginning to sweep industriously as he saw the guard walking toward them. "He didn't like the way we manhandled him."
"You think he was just getting even with us?" asked Astro, also resuming work.
"What else?" asked Roger. "We made him look pretty silly. And that was no love tap I gave him that night we caught him in the hangar."
"That's what I mean," said Astro. "I know Major Connel said he was supposed to be there. But with that teleceiver conversation I overheard and all the rest—well, I just don't get it," he concluded lamely.
"You'll get it in the neck if you don't watch out," said Roger. "Here comes Spike and he doesn't like to see us loafing!"
The two cadets worked steadily for ten minutes, and when the guard finally walked away, they paused to watch the big ship again.
"I wonder what Tom is up to?" said Roger thoughtfully. "He said he knew who the saboteur was, but he needed help to prove it."
"I'd give a full year's leave just to get my hands on that guy for ten minutes," said Astro.
