"I owe Cygni something, too," said Sutton. "I owe Cygni my life. My ship crashed and I was killed."

Adams nodded, almost sleepily.

"Yes, that is what Clark said. That you were killed."

"Who is Clark?"

"Clark is a space construction engineer," Adams told him. "Sleeps with ships and blueprints. He studied your ship and he calculated a graph of force co-ordinates. He reported that if you were inside the ship when it hit, you didn't have a chance."

Adams stared at the ceiling.

"Clark said that if you were in that ship when it hit you would have been reduced to jelly."

"It's wonderful," said Sutton, dryly, "what a man can do with figures."

Adams prodded him again. "Anderson said you weren't human."

"I suppose Anderson could tell that by looking at the ship."
