His last words had an odd sound. It was difficult to know what he meant by them. He might have an intention of returning, or he might not. Perhaps he was uncertain himself. He knew well enough that he might be arrested at any moment, just as his confederate had been. In that case he (Paul) might lie there, bound hand and foot, for days and nights, gradually getting weaker and weaker, and finally dying of starvation. The prospect was not a very agreeable one.

So Paul determined to do his best to free himself of the coils that bound him. He was a strong boy, and struggled might and main to loosen them; but Zuker seemed to have tied them with devilish cunning. Struggle as Paul would, he was unable to loosen them. And the more he struggled, the more the rope cut into his flesh.

"My! The tightest knots I've ever struck," said Paul, as he lay back gasping.

"Paul!"

What was that? An echo, or some one calling him by name?

"Paul!"

There it was again. Surely it was some one calling him. He tried to turn his quivering limbs in the direction whence the voice came. Was he awake or was he dreaming?

The figure of a boy was creeping towards him—creeping, as it seemed to him, from the shadows in the tunnel. Who—who was it? Was it really a being of flesh and blood? At first it seemed to him that it must be the wraith of the little fellow about whom he had been speaking—Hibbert—but even as the thought filtered through his mind the boy was kneeling beside him, looking anxiously into his face.

It was Moncrief minor.

"Harry!" cried Paul in amazement.
