"We'll take a look in there," said Blake, when they had drawn near and had discovered that the ruins of the concrete dugout had been covered with brush, to "camouflage" it from spying airmen.
They approached cautiously, and, as they did so, they became aware of a faint light coming from the ruins. So faint was it that at first it seemed no more than the reflection of the stars, but a long look showed that it was a light from within, but carefully screened.
"We've got to have a look in!" whispered Blake. "Maybe the films are there, and maybe not; but some person is."
"Probably Germans," said Joe.
"Very likely. But it may be that Frenchman. If we could only capture him!"
"I'd like a chance at him!" exclaimed Charlie.
"Hush!" cautioned Blake. The boys were now close to the hut, for that was all it was since the bombardment. They tried on three sides of the place to look in, but without success. Then, as they moved around to the side which faced the German lines, they saw a crack through which the light streamed in greater volume.
"Take a look, Blake," advised Joe.
His chum did so, and, with an exclamation of surprise and satisfaction, turned away from the slot, motioning to the others to look for themselves. And as Joe and Charlie looked they saw, seated on the ruins of a machine gun and other things that had been in the place, Secor and Labenstein. The two plotters had between them boxes which the boys had no difficulty in recognizing as their missing war films.
Joe was about to utter an exclamation of delight when Blake softly put his hand over his chum's mouth.
