"Never I!" cried the Frenchman. "I am a member of the French Secret Service, and for months I have consorted with that dog!" and he pointed at the dead man. "I but played a part to gain his confidence and to learn from what sources Germany was getting her secret information about our soldiers and yours. Now I know. I will explain. But come, we must get out of here."
"Can we get out?" asked Blake.
"Surely, yes. The tunnel goes from here into the German trenches, and the other end was not damaged by the explosion."
"But," exclaimed Joe, "the German trenches! We don't want to go there to be captured again."
"Have no fear," said the Frenchman, with a smile. "I should, perhaps, have said what were the German trenches. They are now held by some of your own troops—the brave Americans!"
"They are?" cried Charlie.
"That is true! You shall see!"
"Hurrah!" cried the moving picture boys, and their fears and weariness seemed to depart from them in a moment.
"The great airship raid was a success," went on the Frenchman. "Our troops and yours have made a big advance, and have captured many prisoners. They would have had Labenstein, but he is beyond prisons now. Let us go hence! Even dead I can not endure his company. I suffered much on his account."
"Well, things are happening so fast I don't know which to begin to think of first," remarked Joe. "But, on general principles, I presume it's a good thing to get out of this tunnel. Come on, boys."
