by Robert Arthur (1980)
A competitor of the Hardy Boys/Nancy Drew books, this Hitchcock-supported series mostly written by Robert Arthur concerns Jupiter Jones and his middle-school-age amateur detective club which operates out of one of the parents' businesses. It's a junkyard, and as such offers lots of cover for the clubhouse location, storage and getaways from nefarious characters. "Fiery Eye" follows the search for a jewel inheritance through a riddle in a poem, clues hidden in Greek and Roman busts and a burial location requiring them to note the angle of the sun at a specific hour without being seen by pursuing crooks. Originally printed in the 1960's and reprinted several times; available today at many used bookstores.

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.
