"And so," he concluded, "we've figured that Chet and Biff may have been kidnapped in mistake for us."
"There's something in that, too," agreed Phil. "And here's something else that may help. I forgot about it when we were searching for the fellows the other day. Just a little while before they went on their trip I was talking to Chet and Biff and I remember that Biff said he had always wanted to visit Blacksnake Island."
"Blacksnake Island!" exclaimed Frank. "That's the place that is overrun with big blacksnakes, isn't it? Nobody ever goes there."
"That's the place, and that's why it's called Blacksnake Island. And you can't blame people for staying away from it—with a name like that. But Biff had read about it and said he wanted to see what the place was like."
"That's Biff all over," agreed Tony. "But did they decide to go?"
"Chet didn't want to go. Blacksnake Island is down the coast, and Chet wanted to go up the coast."
"Sure! That's why we searched up the coast—because Chet said that was where they were going!" Frank declared.
"Well, Biff kept on saying that he wanted to see Blacksnake Island anyway, and while Chet wasn't very much struck with the idea he might have gone there."
"Perhaps they went that way after all. I wish we'd known that when we made our first search. They might have started for Blacksnake Island and got captured on the way." Frank drained the last of his bottle of pop. "Say, I'd like to start another search for them, and go down the coast in that direction. What do you say?"
"I guess I can get away all right," said Tony. "How about you, Phil?"
