"No wars were fought on this planet," Neff spoke quickly. "These cities show no evidence of conflict."

"Um," Thompson said. The four men were looking uneasily at him. They were waiting for him to make up his mind, to decide on a course of action.

Thompson did not like his own thinking. Something—the blood-brother of death—had been here on this planet, that much was certain. The evidence was everywhere.

"We will return to the ship," Thompson said.

Grant saw them coming, had the lock open for them. His worried face looked out at them. "What gives here?"

"We don't know," Thompson answered. The cat, Buster, pushed forward between Grant's legs, took a long leap at Thompson's chest, made a twenty-claw safe landing there. "Hi, old fellow, were you worried about me?"

They passed through the lock. "Take her up," Thompson said. "We need a little time to think about this enigma. Maybe we can think better when we're not so close to it."

At his words, relief showed on the faces of the men. "Maybe sometime soon we'll be heading for home?" Kurkil spoke, grinning hopefully.

"You can be certain of that," Thompson said.
