“Not so loudly,” warned Ollie. “I don’t know where he is now, but I only lost sight of him a few seconds before you poked that gun to my head. He had started for home. He ought to be out there straight ahead somewhere. Wonder where George is?” There was no time to loiter, however, if they were going to capture the man they were after, and after waiting for several seconds without hearing or seeing any sign of their friend approaching, they began cautiously and silently to push forward again. Stretched out almost flat upon the ground, pulling themselves forward by handgrips upon the turf, only occasionally raising their heads to take a hurried but unsuccessful survey of the vicinity to locate the enemy, they finally came upon the first of the bodies over which he had been working. They had made no mistake. The most cursory glance showed that the dead man was a captain in the United States army, and that every pocket of his uniform had been rifled. Not only that, but the shirt beneath had been torn loose and the chest was bared, showing that the most thorough search had been made for anything of value that might have been concealed there. The lads paused for a moment in an effort to identify the officer, but it was out of the question even to attempt to read his identification tag, and a shell fragment had so mutilated his head and face that in the darkness it was impossible for them even to guess who he was. With a suppressed sigh and a muttered threat against the man who thus had defiled the dead, they pressed onward, but without any definite idea as to the exact direction they should pursue, or how far they ought to go. The second body was that of a first lieutenant, and here, also, the search had been complete. The boys had no doubt that each had had upon their persons explicit instructions of the whole advance, at least so far as it was purposed that their units should participate in it, but not the slightest trace of a paper, map or photograph could be found on either of them. Capture of the spy, therefore, was imperative. But where was the enemy who had committed these thefts? A few moments before he had been plainly visible to Ollie. The latter had crouched down again to continue his own advance, and when he again looked, the man had disappeared completely. True it was a dark night; but the open space was broad, and he had been clearly silhouetted against the skyline. It was inconceivable that he could have covered a sufficient distance in the meantime to take him out of sight of the lads. They decided, therefore, to continue on.
