"I've known this man for years. This is Eddie Nevins."

"And this is Sam Reese."

Hargraves heard the voices, saw the conclusion they were reaching.

"One moment," he said.

The voices went into silence. Eyes turned questioningly to him.

"Even if these men are really Hal Sarkoff and Eddie Nevins and Sam Reese, if they are the companions we knew as dead who have miraculously been returned to us, there are still facts that do not fit into a logical pattern. Even here on this world the laws of logic must hold true."

Silence fell. Men looked at him and at each other. Where there had been wonder on their faces, new doubts were appearing.

"What facts, Jed?" Sarkoff questioned.

"The sphere that attacked us, that attempted to destroy us, without warning. This is a fact that does not fit."

"The sphere?" Uncertainty showed on Sarkoff's face. Then he grinned again and turned to Thulon. "You tell him about that sphere."
