“Brace up, Blake, and show that you can stand whatever may be coming,” he managed to say in a low tone to his companion.

Then the commander of Battery K arrived. He was a bluff sort of a man, not much given to beating around the bush when he had anything to say; nor could he smooth over disagreeable news as some men might.

“I’m sorry to report that young Gregory seems to have disappeared from camp altogether,” he immediately remarked. “It is a most extraordinary occurrence. In fact, several officers with whom I’ve spoken say they would never have believed a man could vanish from the midst of a thousand or two of his fellows, with sentries posted, and camp rules in force. But I’ve sent out in every direction to find Gregory, but without any success so far.”

Both Blake and Bud left things pretty much to Hugh, knowing his ability to handle such a case. Like a wise scout, the patrol leader immediately began to ask questions, with the design of getting facts that might give them a clue to the solution of the camp mystery.

“Several men seemed to agree on that point,” replied the accommodating officer, “and I am inclined to say that it was just about half an hour back. At the time he was talking with a civilian who had managed in some way to gain permission to enter the camp in his car. From what I have learned, I believe Felix appeared to be considerably excited while he held this conversation with the stranger.”

“Hugh, just as we suspected, it must have been that man!” gasped Blake. Bud Morgan nodded his head, and pinched the other to keep him quiet.

“Did any of them describe the man and his car, Captain?” continued Hugh. “You remember what we told you about the party who gave us so much trouble on the road? He was a small fellow, with a dark face, and snappy eyes, and his car was one of that cheap class called a flivver. Does that agree with what any of the men said, sir?”

“It seems to cover the case exactly, Hugh,” the officer hastened to admit; “and, taken in conjunction with your remarkable story, makes the matter seem more mysterious than ever. Apparently, then, that man who tried to prevent you from getting to camp, finding that all his schemes had failed, turned another tack, and now aims to keep Felix from seeing you. How he has been able to get him out of the camp beats me; it would seem to be an impossible task.”

Hugh was on his mettle now; his fighting blood aroused. The gleam in his eyes told that, as he shut his teeth together with a snap, and went on to say:
