DESCRIPTION: From the description:

FRANK and Joe Hardy are called upon to find a wealthy industrialist'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.  


********

This copy is dated to roughly 1976 based on the order blank at the back of the book, which lists available titles through "The Witchmaster's Key". Illustrated with line drawings. Endpapers use the classic line drawings from previous book covers, which replaced the sepia-toned endpapers of the 1960s.  

CONDITION: Front cover looks good, bumping to head and tail of spine, and rear cover has scuffing and some mid-intensity dark stains, with the cover price of the book marked over in permanent marker. Contents appear entirely clean and unmarked, order form is included.
