A moment later, however, he heard some one approaching through the woods behind him, and a voice called out: 

“What are you doing?  Get away from there!”

Rapid footsteps sounded, and Tom, in a panic, turned and fled, with an unknown pursuer after him.

CHAPTER XXIV.

UNEXPECTED HELP

Tom rushed on through the woods.  The lighted room into which he had been looking had temporarily blinded him when it came to plunging into the darkness again, and he could not see where he was going.  He crashed full-tilt into a tree, and was thrown backward.  Bruised and cut, he picked himself up and rushed off in another direction.  Fortunately he struck into some sort of a path, probably one made by cows, and then, as his eyes recovered their faculties, he could dimly distinguish the trees on either side of him and avoid them.

His heart, that was beating fiercely, calmed down after his first fright, and when he had run on for several minutes he stopped.

“That—­that must—­have been—­the—­the man—­from the boat,” panted our hero, whispering to himself.  “He came back and saw me.  I wonder if he’s after me yet?”

Tom listened.  The only sound he could hear was the trill and chirp of the insects of the woods.  The pursuit, which had lasted only a few minutes, was over.  But it might be resumed at any moment.  Tom was not safe yet, he thought, and he kept on.

“I wonder where I am?  I wonder where my motor-cycle is?  I wonder what I had better do?” he asked himself.

Three big questions, and no way of settling them; Tom pulled himself up sharply.

“I’ve got to think this thing out,” he resumed.  “They can’t find me in these woods to-night, that’s sure, unless they get dogs, and they’re not likely to do that.  So I’m safe that far.  But that’s about all that is in my favor.  I won’t dare to go back to the house, even if I could find it in this blackness, which is doubtful.  It wouldn’t be safe, for they’ll be on guard now.  It looks as though I was up against it.  I’m afraid they may imagine the police are after them, and go away.  If they do, and take the model and papers with them, I’ll have an awful job to locate them again, and probably I won’t be able to.  That’s the worst of it.  Here I have everything right under my hands, and I can’t do a thing.  If I only had some one to help me; some one to leave on guard while I went for the police.  I’m one against three—­no, four, for the man in the boat is back.  Let’s see what can I do?”

Then a sudden plan came to him.

“The lake shore!” he exclaimed, half aloud.  “I’ll go down there and keep watch.  If they escape they’ll probably go in the boat, for they wouldn’t venture through the woods at night.  That’s it.  I’ll watch on shore, and if they do leave in the boat—­” He paused again, undecided.  “Why, if they do,” he finished, “I’ll sing out, and make such a row that they’ll think the whole countryside is after them.  That may drive them back, or they may drop the box containing the papers and model, and cut for it.  If they do I’ll be all right.  I don’t care about capturing them, if I can get dad’s model back.”
