“I watched my chance and took the key from old Crabby’s pocket.”

“Good for you!”

“Now unfasten my bracelets, will you?”

“Certainly.”

With their hands at liberty, the boys felt a trifle better. But the semi-darkness and the heat did not suit them at all. Besides this, the hot stone room was full of a dry dust that set them to coughing.

“I’d like to put old Crabtree in this place,” muttered Jack.

“I wonder if we can’t get out, Jack?”

“What good will it do?”

“A lot of good. We can remain out of Crabtree’s reach until Captain Putnam gets back. Then we can demand a hearing.”
