"You take this knife, Gregory," said Chester. "I wouldn't know what to do with it."
Hal approached the canvas door to their prison and poked his head out.
"Get back there!" came a guttural command in German.
Hal spied a sentry standing before the tent.
"Hello," he said pleasantly. "Didn't know you were there. All by yourself, too, eh?"
"Not much," was the reply. "There's a man in the rear, too."
"I just wondered," murmured Hal.
"Get back inside," commanded the guard.
"Oh, all right," said Hal, "if you are going to be nasty about it.
But, say, do you have a pack of cards you can lend us?"
"No, I don't," said the guard.
