The Mystery of Cabin Island (The Hardy Boys Mystery Stories Book 8)

With two mysteries to solve, Frank and Joe must climb aboard their iceboat the Sea Gull to reach Cabin Island, where a belligerent stranger orders them off. Sabotage to the boat, danger to themselves, and a ghostly prowler do not daunt the Hardy boys in their search for Johnny Jefferson and for clues to stolen antique medals. How the teenage investigators outwit a ruthless foe and succeed in solving both mysteries makes for mounting suspense in this brisk-paced adventure.
