"I'm just refreshing your memory, General," Capper hastened to reassure. "Just reminding you that there isn't much difference between a German and an Englishman, after all—if the German wants to play the Englishman and knows his book. He can fool a lot of us."

"Have you seen Captain Woodhouse, General?"

"Not a half hour ago. He called to report."

"Seemed all right to you—this Woodhouse?" Capper eyed the other's face narrowly.

"Of course. Why not?"
