“You didn’t?”
“No. You see we ran across what you might call unsurmountable obstacles, so to speak.”
“But what—”
“I’ll tell you all about it,” Bob interrupted, and proceeded to give him a full account of their adventures.
“Well, of all things,” Mr. Sleeper declared as he finished. “Why didn’t you call me on that radio set?”
“Well, you see, while we were tied up we couldn’t and after we got free and got our things back we figured that we’d better get away without any unnecessary delay,” Bob told him.
“But you say there was no way to get out of that cave except through the door?”
“I said we couldn’t find any. Of course there must be a way. A man can’t just naturally evaporate, you know.”
“No, but isn’t it possible that there was some place in the cave where he could hide?”
“It’s possible, of course, but we didn’t find any,” Bob assured him.
