He would shout and maybe some one would come.

He tried it; but in the darkness the distant echoes sounded so hideously that he tried it no more.
The hours wasted away, and hunger came to torment the captives again.
A portion of Tom's half of the cake was left; they divided and ate it.
But they seemed hungrier than before.

The poor morsel of food only whetted desire.
By-and-by Tom said: "SH! Did you hear that ?" Both held their breath and listened.

There was a sound like the faintest, far-off shout.

Instantly Tom answered it, and leading Becky by the hand, started groping down the corridor in its direction.
Presently he listened again; again the sound was heard, and apparently a little nearer.
"It's them!" said Tom; "they're coming! Come along, Becky--we're all right now!" The joy of the prisoners was almost overwhelming.
