"He'll reason that he's a dead man if we get him and he might as well die fighting," remarked Frank, as with his comrades he picked his way through the woods.

"Righto," agreed Tom. "And even if he didn't have a weapon when he escaped, there are lots of them lying around and he won't have any trouble in picking one up."

"I wonder if he'll stick to the horse," mused Bart.

"I hardly think so," replied Billy. "He knows from the shots that were sent after him that we know he used a horse in escaping and will be looking for a man on horseback. So he'll try to deceive us by going on foot."

"He'll probably hang about in the woods until it's pitch dark and then try to get through the lines," said Frank. "He may be behind any tree or bush, and we want to be mighty careful to examine each one as we go past it."

"Maybe he'll climb a tree," suggested Tom, looking up to the branches of one he happened to be under at the moment.

"Not a chance at this time of the year," objected Billy. "There aren't any leaves to hide him, and even in the darkness we could probably see his outline against the sky. Then, too, if he were seen he could be potted too easily. No, he's not up a tree."

"Queer that he should have got away so soon after we'd been down to the hut," remarked Frank.

"Queer!" snorted Tom. "It isn't queer at all to my way of thinking. The whole thing was cut and dried."

"Then you think that Rabig was in cahoots with him?" asked Bart dubiously.

"I'm sure of it," responded Tom. "Use your common sense, fellows. We see half a dozen suspicious things that look as if Rabig and the prisoner had some understanding. A little while after the prisoner escapes.

What's the answer?"

"The answer might be several things," replied Frank, who hated to believe evil of even his worst enemy. "A lot of things are due to coincidence. It may be perfectly true that Rabig was in sympathy with the German, but that doesn't say that he'd go so far as to let him actually escape. He was taking big chances with his own skin in doing it."

"Besides, there's no doubt that Rabig was wounded," remarked Bart. "That fellow seems to have given him an awful knock. He was bleeding like fury."

"Oh, it was easy enough to arrange that," answered Tom, unconvinced. "It would have been too raw to have Rabig let the fellow go and still be safe and sound. How could he explain it? He'd be brought up for court-martial. But a scalp wound could be easily made where it would produce the most blood and do the least harm."

"But what object would Rabig have in taking such chances?" asked Billy.

"The fellow had been searched and couldn't have had any money with him."

"No, but he could have promised plenty," argued Tom. "Perhaps he's told Rabig that the grateful Kaiser would make him rich. How do we know that Rabig wouldn't fall for that? He's got an ivory dome anyway. If there were more than two ideas in his head at one time they'd be arrested for unlawful a.s.semblage."

The boys laughed and Tom went on:

"Besides, how do we know but what Rabig is planning to desert and wants to pave the way for a warm welcome on the other side? It would be easy enough to slip across while the lines are so near each other."

"But Rabig seemed to be pretty badly hurt," said Billy. "You saw him faint."

"Which only proves that he is a good actor," retorted Tom dryly. "Don't think me hardhearted, fellows, because I'm not. I'm always ready to give everybody his due. But I feel sure down in my heart that this thing was all fixed up beforehand, and some day you'll find that I'm right."

For more than two hours they kept up the search without result, and the fact that they had not had their supper was forced upon them with growing insistency.

"Isn't there any time limit to this?" grumbled Bart. "I'll be hunting for acorns instead of a prisoner before long."

"I've got a vacuum where my stomach ought to be," moaned Billy. "Gee, wouldn't I like to be streaking it for the mess room."

"Cork up, you fellows," commanded Frank. "Listen! I thought I heard something just then."

The talking ceased instantly, and all stood as rigid as statues.

"It's a horse coming this way," whispered Frank, after a moment of strained attention. "Quick, fellows, get behind these bushes and have your rifles ready!"

They crouched low and peered up a little glade that ran through the forest.

But the noise ceased as suddenly as it had begun and they began to think that their comrade had been mistaken.

"Guess Frank's been stringing us," chaffed Billy.

"He's the only one who seems to have heard anything," said Tom.

"Don't you worry about my hearing," said Frank. "I tell you I heard a horse's hoofs. Perhaps the rider suspects something and is trying to get a line on us, just as we're trying to get one on him."

"It may have been a horse all right," said Billy, "but that doesn't say he had any rider. He may be rambling around all by his lonesome, and perhaps he's stopped to graze somewhere."

"There he goes again!" exclaimed Frank, and this time every one of them heard what was undeniably the thud of a horse's hoofs.

But there was a hesitation, an uncertainty about the animal's movements that seemed unusual. It moved as though it had no purpose in view no guiding hand on the reins. At times the canter seemed to subside into a walk. There was something about this unseen steed, at large in the dim forest, that gave the boys a most uncomfortable feeling.

Then suddenly a more resolute note in the sound and an increase in its volume told the listening boys that the horse was coming straight toward them.

The clatter of hoofs drew nearer, and they clutched their guns more tightly.

Soon they were able to distinguish in the gloom the outline of a horse and rider. The man's figure loomed up huge and threatening, and they felt sure that it was the big German corporal for whom they were searching.

The boys waited until the horse was almost upon them and then rushed out into the road.

"Halt!" cried Frank. He seized the horse's rein while the others leveled their rifles at the rider.

The horse reared in fright, but the rider made no answer nor did he attempt to draw a weapon.

"Get down!" commanded Frank. "We've got you covered. Surrender."

Still the rider remained silent.

Frank having quieted the horse went alongside and put his hand on the man's arm.

"Come----" he began, then stopped suddenly.

There was a moment of utter silence, and Frank for the first time in his life could feel the hair rising on his head. Then he controlled himself.

"Put up your rifles boys," he commanded. "The man is dead!"
