“It wouldn’t have been hard to slip past a sentry in the pouring rain, sir,” suggested Jordan.
“No, not at all,” agreed the colonel. “With this reference to your soldiering, I presume that you young men will have an added cause now to go after this ghost person.”
“That’s a pretty heavy insult!” smiled Major Rhodes.
“Well, the ghost must know now that an active campaign is afoot to drive him off the Ridge,” said the colonel. “That ought to make the game more interesting than ever. Our foe is warned and will play his game with skill. That gives you boys greater odds to move against, but I feel sure that you will be successful in making an end to the affair.”
The regular routine of that day seemed to take longer than usual, but as soon as it was over the members of the Ghost Patrol gathered together to look around in back of the camp for signs of the night visitor. The ground was wet and they argued that if the prowler ever left any traces he would surely have done so that night. Their first search took in the soft soil back of Jim’s tent and they found encouraging signs at once.
“More than one footprint here,” proclaimed Don, grimly, as they bent over the depressions in the dirt.
Someone had sneaked up close to the wall of the tent, and the prints of large shoes were very plain. In the heels of the left shoe they found a peculiarity that gave them something to work on. There had been some kind of a cut down the center of the leather heel and it showed plainly in the soft mud.
“Maybe when the heel was cut out of block leather the knife slipped and left that mark,” Jordan thought. “With a plain marking like that we ought not to have much trouble. Let’s look under that tree where the cardboard was found.”
Under this tree they had more difficulty, because the feet of the curious cadets had churned up the ground so that it was almost impossible to make out anything definite. But at a distance of perhaps three yards they found the marked heel print again. Whoever had placed the sign in the tree had come down the slope above the camp, and the print could be followed for a short distance up the hillside. But before long they struck a section of rocky ground and hunt as they would they could not find another trace of the print.
