Frank and Joe Hardy are called upon to find a wealthy industrialists's son who has mysteriously disappeared. Did Graham Retson flee from his home because he was at odds with his father, or was he kidnapped? Finding the answer turns into something more dangerous and larger in scope than Frank and Joe ever bargained for. The only clue in the case leads the two young detectives to South America, where the intrigues of evil adversaries almost cost them their lives. Involved in this complex mystery are a fierce-looking monkey trained to be a killer, a school of voracious, man-eating piranhas, a ruthless gang of passport thieves, and a cleverly operated change-your-identity mill for criminals. Only through their courage and perseverance do the Hardys solve one of the toughest cases they have ever tackled. - Flyleaf.
