Frank and Joe are an accident waiting to happen when they go undercover to expose sabotage! The Shorewood Nature Center is a beautiful place to hike...to learn about local ecology...or to fall off a cliff. The Hardys learn that the hard way when they go undercover to investigate strange happenings on the grounds. In no time at all, they get jumped, smoked out, and booby-trapped. The Hardys have never run from a challenge, and they're not about to start now. Someone will do anything to shut the center down, and Frank and Joe have a clue why: there's a secret buried somewhere on the center's grounds—a very valuable secret that's worth a lot more than the lives of two young detectives!
Franklin W. Dixon is the author of the ever-popular Hardy Boys books.
