"Be quiet, Billy!" barked his father.

Roger's face turned a slow red while Tom and Astro grinned. After a few more words, the three cadets again headed for the jet-boat deck.

"That Billy will make a fine radarman someday," drawled Astro.

"How do you figure that, Astro?" asked Tom.

"Did you see the way he spotted Roger's roving eye looking for his pretty sister? Why, in ten years, he'll be picking up asteroids the same way."

Back in their jet boat a few minutes later, blasting through s.p.a.ce on the rest of their tour, Tom turned to his unit mates, a troubled look on his face.

"Did you notice anything aboard Number Twelve that looked--well, suspicious?" he asked.

Astro and Roger shook their heads.

"Me neither," said Tom. "Maybe we've got Vidac pegged wrong. Maybe--"

"I thought of that, Tom," interrupted Roger. "But there's one thing that doesn't seem right."

"What's that?" asked Tom.

"Your report to Captain Strong," Roger replied. "You sent it to him ten days ago. You should have had an answer by now."

"He's out on Pluto," said Astro. "s.p.a.ce Academy might not have forwarded it to him."

"You know the rules," said Roger. "Any official communication to a Solar Guard officer is sent through regardless of where he is in the universe, if communications are at all possible."

"You're right, Roger," said Tom finally. "I should have had some sort of answer by now."

"You think," mused Astro slowly, "maybe Vidac didn't send the report?"

Roger hesitated and then replied, "There's one way to find out."

"How?" asked Tom.

"Take a look in the communications logbook on the control deck."

"We can't, Roger." Tom shook his head. "Vidac's got his own men planted in every one of our departments."

"Yeah," growled Astro. "I been watching the way that guy Smith takes care of the power deck and, believe me, it makes me burn. Why, he hasn't washed down the atomic motor casing once since we blasted off!"

"Wait a minute!" cried Roger suddenly. "Jeff Marshall!"

"Jeff?" asked Tom. "What about him?"

"He can get to the control deck and take a look at the logbook,"

answered Roger.

"Say, that's right," said Tom.

"Come on," said Roger. "Let's finish off this tour and get back to the _Polaris_. If Vidac's on the level, he'll have sent your report to Captain Strong. If not, we know where we stand."

Astro shook his head slowly. "Honestly, fellas, I don't know whether to hope he did or didn't."

Their tour completed, the three cadets returned to the _Polaris_. They quickly audioscribed their report to Vidac and then hurried to the observatory to find Jeff Marshall. Luckily the sergeant was alone and they were able to give him all the reasons for their suspicions of Vidac and tell him what they wanted him to do.

"But what can I say I'm looking for in the logbook?" Jeff Marshall protested.

"We pa.s.sed through a cloud of meteor dust the other day, didn't we?"

asked Tom.

"Yeah," replied Jeff, "but what's that got to do--"

"You had to report it to central weather control," said Tom. "Tell the pilot you lost your own copy of the report and want to get the official path out of the log. Tell him the professor wants it."

Jeff thought a moment, then nodded his head. "O.K. I'll see you later."

The three cadets returned to their quarters to wait while Jeff went up to the control deck. He walked in with a smile, chatted with the pilot a few moments, and then made his request.

"I want to take a look at the log a minute, Johnny," he said casually.

"The professor lost his notes on the meteor dust we pa.s.sed through the other day."

"Sure," said the pilot. He tossed the dog-eared book to the sergeant.

Jeff flipped through the pages and found the day Tom's report was to have been sent. He checked carefully, continuing through the entries for the succeeding days, ending with the last entry made just an hour before. There was no mention of Tom's report. Jeff turned to give the logbook to the pilot when Vidac and Professor Sykes stepped through the hatch. Seeing Jeff with the log in his hands, Vidac frowned.

"What are you doing here, Marshall?" he snapped.

Jeff was trapped. He came to attention and remained silent. Vidac walked across the control deck and stood in front of him.

"Well, Marshall?" he barked. "Answer me!"

"I needed some information about the meteor dust we pa.s.sed through recently, sir," said Jeff.

Vidac turned to the professor. "Did you send him up here?"

Sykes merely shook his head.

"I lost the professor's notes and needed the information in the logbook, sir," said Jeff.

"What are you talking about?" growled Sykes. "The notes are still in my work journal. You put them there yourself!"

"What have you got to say to that?" demanded Vidac.

"I repeat, sir," said Jeff, "that was my reason for looking in the log."

Vidac paused, and when he spoke, his voice was cold. "The control-deck logbook contains cla.s.sified information, Marshall. You know that. I won't say you're lying about reasons for looking at it, but that does not excuse the fact that you _did_ look at it without my permission. I'm confining you to the brig for ten days."
