Joe and Biff found themselves roughly hauled to their feet, their arms held tightly behind them. They heard the clatter of footsteps as two of the other men ran after Frank and Chet.
"Back to the cave with 'em," growled Red. "Looks like we've got one of the guys that helped 'em get away. I've been thinkin' all day that there was some one hangin' around here that we didn't know about."
The lads were shoved and pushed ahead of their captors, dragged and bundled across the rocks until they reached the cave. Then they were roughly shoved through the entrance into the light of the fire.
"Ah! I thought so!" declared Red. "One of the guys that tried to help them get away." He peered closer at Joe. "Blessed if it ain't one of those two boys that was in the boat with the Hardys that day."
One of the other men ordered the boys to sit down, and they crouched beside the stirred-up fire, sick at heart, wondering how it fared with Frank and Chet.
When Joe and Biff were captured it was Chet's first impulse to turn and go back, but a warning shout from Frank restrained him.
"Keep running!" he called. "If they're caught we'll have a chance to get help."
The wisdom of this course flashed through
