The lieutenant was taken aback.

"Why, I know no reason," he said, "except that your presence in our company, if ill fortune should befall us, would probably mean your arrest as enemies of Germany. You might even be convicted as spies, and shot."

"We are willing to take any chances necessary to get us to Brussels and put an end to mother's worries," declared Hal stoutly. "Aren't we, Chester?"

"You bet we are," replied Chester.

The lieutenant turned to Captain Derevaux. "What do you say?" he asked.

The captain shook his head.

"It's a bad business," he replied slowly. "If we are caught it will go hard with our young friends, I am afraid. Of course, I am willing to do anything in my power to aid them, but this—this, I fear, is impossible."

"Don't say no," implored Hal. "Just think how mother must be worrying. Why, we would go through anything to save her pain. Besides, you don't expect to be captured, do you?"

The captain shook his head.

"You have a good plan of escape, I am sure, or you would not tackle it.
Isn't that so?" continued Hal.
