Tom Swift and his Motorboat
by Victor Appleton
Tom Swift's father, a world-renowned scientist, has been robbed of one of his greatest inventions, and Tom must bring the culprits to justice without killing himself in the process. Unfortunately, Tom himself quickly becomes the target of the wrath of the scoundrels when he unknowingly buys a boat in which they hide a stolen diamond. He must use every bit of his wits to keep himself in front of a gang of criminals. (source: Wikipedia)
