His revolver gleamed in his hand as he spoke, and he took a step forward. The German moved back a pace, but he made no further move to draw his weapon.

"Now that you have recognized me," continued Chester, "I would advise you to come along with us. We can't afford to let you go back and set up an alarm, you know. I don't want to shoot you, for I remember that I owe my life to you. Walk on ahead of us, now!"

He emphasized this last sentence with a flourish of his revolver, and the German, realizing that a refusal to obey might possibly spell death, obeyed.

"Sorry I didn't place you at once," he exclaimed. "Then I guess we would be going the other way."

"I wouldn't be so sure about that," Hal broke in. "We usually go the way we want to."

Half a block farther on Hal perceived a body of German troops moving toward them.

"Step in between us," he commanded the prisoner.

The latter obeyed without remonstrance.

"One false move and you are a dead man, no matter what happens to us," said Chester quietly.

The prisoner recognized by the lad's tone that he was in earnest, and he would have passed right on, but an officer with the approaching troop walked directly up to him and saluted.
