Roger agreed with a nod of his head. "There's only one thing that bothers me now."

"What's that?" asked Astro.

"Professor Sykes," he said. "We've been so worried about our own necks, we've forgotten about him."

"Well," said Astro, "what about him?"

"What really happened to him," mused Roger, "and why?"

"I wish I knew," said Tom. "But I'll bet Vidac knows."

"Sure," agreed Roger. "But I still say why and what?"

The blond-haired cadet looked around at the faces of his friends. There was no reply to his question.


Every citizen of Roald, man, woman, and child, was at the spaceport to watch the giant cruiser Orion settle slowly to the ground. Vidac watched it through squinting eyes. He had secretly hoped that the uranium disturbances would cause the ship to crash, thus eliminating his difficulties before they could begin, but he couldn't help admiring the way the big cruiser was handled. When the hatch opened and Captain Strong stepped out, resplendent in his black-and-gold uniform, there was a spontaneous roar of welcome from the ground. Vidac stepped forward immediately to greet the Solar Guard officer.
