It was true. Tawney had recovered from his shock ... but rather than grow more worried as Mars grew large on the screen, he seemed to become more cheerful by the minute. "He doesn't seem very worried, does he?" Tom said.

"No, and it doesn't quite add. We've got enough on him to get Jupiter Equilateral pushed right out of the Belt."

"I'd still feel better if we had the whole picture for the Major," Tom said. "We still don't know what Dad found, or where he hid it...."

The uneasiness grew. Tawney ignored them, staring at the image of the red planet on the viewscreen almost eagerly. Then, eight hours out of Sun Lake City a U.N. Patrol ship appeared, moving toward them swiftly. "Intercepting orbit," Greg said. "Looks like they were waiting for us."

They watched as the big ship moved in to tangential orbit, matching its speed to theirs. Then Greg snapped the communicator switch. "Sound off," he said cheerfully. "We've got a prize for you."

"Stand by, we're boarding you," the Patrol sent back. "And put your weapons aside."

Four scooters broke from the side of the Patrol ship. Greg activated the airlock. Five minutes later a man in Patrol uniform with captain's bars stepped into the control cabin, a stunner on ready in his hand. Three Patrolmen came in behind him.

The captain looked around the cabin, then saw Tawney, and took a deep breath. "Well, thank the stars you're safe at any rate. Pete, Jimmy, take the controls."

"Hold on," Greg said. "We don't need a pilot."

The Captain looked at him. "Sorry, but we're taking you in. There won't be any trouble unless you make it. You three are under arrest, and I'm authorized to make it stick if I have to. I suggest you just cooperate."
