didn't sleep at all last night."

"He better keep awake," said Roger. "That little fireman's got his
rockets hot tonight. He'll blast Tom sure if--"

"Wait a minute," said Astro suddenly, looking off into the darkness.
"What was that?"

Roger spun around, his rifle in his hands, ready to fire. "What is it?"
he asked.

"I don't know," replied Astro in a whisper. "I thought I saw something
move inside the hangar." He pointed to a large window. "Sort of a shadow
against the frosted glass."

"Are you sure?"

"Of course I'm sure."

"I'll investigate. You get Tom and call Firehouse."

"Right," replied Astro, and raced down the path, alongside the hangar.

Grasping his rifle firmly, Roger inched toward a nearby door. He opened
it a crack, then flattened himself against the wall and watched Astro
run toward the other end of the hangar. He saw the big Venusian say a
few quick words to Tom and then rush off toward the guardhouse and the
communicator. Tom waved to Roger, indicating that he would enter the
opposite door of the hangar.
