"What kind of questions?" demanded Barret.
"I'm not allowed to tell you."
"What were you doing here the other night?" pursued Barret. "The night you saw me here."
"I came down to check our supplies. I knew that we were running short on certain equipment."
"What kind of things?" demanded the professor.
"Well, the timers on the oscillators," Troy replied. "I knew we would need them for the new units you and Commander Walters were planning."
"Guard!" shouted Barret suddenly. "Guard!" He turned and called to Roger and Astro, who were standing guard at the doors. They both came running up, their blasters held at ready.
"What is it?" demanded Astro. "What's going on here?"
"Arrest that man!" shouted Barret. Astro and Roger looked questioningly at Troy. They did not know him personally but had seen him around the hangar and knew that he worked closely with the professor and Barret.
Still vaguely distrustful of Barret's behavior, Astro turned to Hemmingwell. "How about it, Professor?" he asked. "Do we haul this guy in?"
