“Of course,” Bob replied as he cut the rope which bound his hands and feet. “Are you all right?”

“Sure only a bit stiff.”

“Then let’s get out quick.”

“Why the rush?”

Quickly Bob explained the situation. “Those fellows may be back at any minute,” he finished.

Bob crawled through the hole closely followed by Jack and had just gotten to his feet when a shaft of light was shot through the opening above.

“Get back, quick,” he ordered.

“Of all the luck,” Jack groaned as soon as they were back in the larger chamber again.

“Either they’ve come back or that fellow’s got loose,” Bob said, “and I don’t believe he got that cord off by himself.”

“And we’re caught like rats in a trap.”
