"Well, it's a good day's work. I'm goin' to sleep," said one of the other men. He pulled a blanket about him and curled up beside the fire.
"Good idea," remarked Red. "We might as well all turn in."
Shortly afterward, the various members of the gang were sprawled about in their blankets on the sand. Frank noticed that they all slept on the same side of the fire, and also noted that the reason for this was that on one side of the cave the floor was a ledge of rock.
"We'll wait till they go to sleep," he whispered to Joe.
His brother nodded. The two boys remained crouched among the rocks. The rain had died away to a mere drizzle.
Gradually the fire, untended, died down, and there was only a faint, rosy glow through the interior of the cave. Two or three of the men had talked together in low murmurs for a while, but gradually their voices died away and soon the boys could hear their snores. It was nearly an hour, however, before they were satisfied that all the men were asleep.
"I'm going in after Chet and Biff," whispered Frank, with determination.
"I'm with you."
"The keys are still lying beside the fire."
"Good."
