"This chase. That man knows what he's doing and we don't. If he wanted to he could have been out of this cave a dozen times or more, yet he's staying in and leading us on. He has some object in it, and I don't mind confessing that I'm afraid of it."
"How do you mean afraid?"
"I think we may come to some harm. He fairly enticed us in here and now he's playing with us as a cat does with a mouse. I'm going to stop and go back to the entrance."
"Well, perhaps you're right," admitted Andy, and it was quite an admission for him, as he was always willing to take more risks than was his brother. "We'll stand still a few minutes and see what happens."
They remained there, quiet in the darkness. For a time not a sound broke the stillness. Then, with startling suddenness came a hail:
"Well, why don't you catch me?"
"Catch me?" repeated the echoes, and there followed a mocking laugh.
"Here he is!" cried Andy. "Off to the left."
"No, the right," insisted Frank. "Over this way."
"All right," agreed Andy, and he followed his brother.
