CHAPTER XVI
The Alarm
The Hardy boys were quivering with excitement. They had found the whereabouts of their chums; they had learned the dismaying news that Fenton Hardy had been captured by his enemies; they had discovered the hiding place of the gang. All this had taken place in a few fleeting hours.
Their first problem was to release Chet and Biff. But at first glance that seemed impossible. For when Pete came back into the cave he flung a bunch of keys into the sand beside the fire and laughed harshly.
"They'll get tired bein' chained up to a rock after a few more days," he said. "They'll come through yet."
"We can wait as long as they can," declared Red.
"If they'll only write a letter to their mother now and tell her we want that ransom we'll be sitting pretty. Fenton Hardy can't come after them—that's certain."
