Half an hour later they were out of sight of the prison camp. It was then that Chester leaned forward and touched Hal on the arm.

“Which way now?” he asked.

“I judge that this road will take us to the Swiss border,” said Hal.

“Right you are,” agreed Harding.

“Trouble is,” said Chester, “that we don’t want to get out of Germany just yet.”

“What!” exclaimed Harding.

“Chester is right,” Hal put in. “You see, Harding, we haven’t yet obtained the information we came after.”

“By Jove! So you haven’t!” exclaimed Harding. “Well, what are you going to do about it?”

“Get it,” returned Hal briefly.
