“Unless there’s another way out. But we’re safe for the present. They won’t dare come down that ladder. I’ve got that fellow’s gun and he knows it.”
“But why, in the name of common sense, did they let us know that they had come back? If they had waited till we got out they could have caught us without much trouble, that is if the others are really back.”
“I was thinking of that very thing myself.”
“Well, what about it?” Jack asked as Bob paused.
“I don’t know the answer, if that’s what you mean.”
“Well, I don’t know as the answer’s the important thing just now after all. How are we going to get out, is the big question.”
“I’m afraid it’s too big,” Bob sighed as he threw the rays of his light about the room. “Do you suppose there’s any back door to this place?”
“It seems to me that there must be because when you lifted up that trap, I thought I could feel a draft, but of course I might have imagined it.”
“Well, here goes for a search. You stay here and if you hear anything suspicious let me know.”
While he was speaking Bob was moving about the chamber examining the walls but, after he had made a complete circuit, he had to confess that he had found nothing which promised the faintest hope.
