The searchers now did the simple, obvious thing.

They divided the grounds up into sections, and beat over each section thoroughly, with the result that a corporal and a private speedily came upon Boris and Fred, and, raising a sort of view halloo, dragged them out into the open, flashing their electric torches in their eyes.
"Here they are!" cried the corporal.

"Herr Hauptmann, here they are!" A captain came up quickly, and at the sight of Fred exclaimed sharply in his surprise.
"You're the boy I chose to help with the work in the house here!" he said.

His face darkened.

"He is a spy! Take him into the guard room and lock him up." He barely glanced at Boris.
