MK's Detective Club: The Double Trouble Puzzle

Join the best kid's detective club EVER in this mystery series of thrills, chills, laughs, and unforgettable characters—from #1 bestselling mystery maven James Patterson

Minerva Keen is the absolute best kid detective Chicago has ever seen, and she’s hungry for a new mystery to solve with her friends. But a know-it-all new girl, Zoe, tries to take control of MK’s detective club. Worse still, Ms. Claire Voyant, who has always had a soft spot for Minerva, takes Zoe's side. It’s clear to Minerva that someone…or something has taken over her favorite teacher.

Add in terrifying nightmares, the return of Minerva’s parents (who come home with more dangerous baggage than just their luggage), and some shocking developments—MK’s Detective Club might have more mysteries than they can solve. With nowhere to turn, the club walks right into danger…and the stakes just might be deadly.
