“Listen,” whispered the older one. “Do you hear him?”
In the silence and blackness there came to them the sound of retreating footsteps, and of small stones and particles of earth falling.
“He must be climbing up,” said Andy. “This cave is bigger than we thought, and he must know the place, even in the dark.
“It is as dark as a pocket,” complained Frank. “I can’t see anything.”
“Wait!” suddenly exclaimed Andy. “Why didn’t we think of them before? Our pocket electrics. They’ll do the trick!”
“Sure enough.”
An instant later two small but powerful gleams of light cut the blackness of the cavern, and the boys were enabled to see so they could hurry ahead. They could still hear the man retreating before them.
“We’re coming!” cried Andy in reckless bravado.
“Hush! He’ll hear you,” cautioned his brother.
“What of it? I want him to. He’ll see our lights anyhow. But I think we have him trapped.”
