I love a good puzzle. But even more, I love a book with a good puzzle! This list of puzzle mysteries is fantastic for any kid who loves to solve problems and look for clues. Although I have an additional middle grade mystery book list and an early chapter book list of mysteries, I chose titles for this list based on their density of conundrums, brainteasers and puzzles that junior sleuths must piece together. Many of these mysteries also require the protagonists to crack codes and go on scavenger hunts. All in all, they are the kinds of books that keep kids reading long after bedtime!
These books are great for ages 8-12, and make excellent read alouds, too. Why not get the whole family involved for a little puzzle-solving and choose a title for family read aloud night! (Note: book covers and titles are affiliate links)
The Ambrose Deception by Emily Ecton. Three middle school contestants, Melissa, Wilf and Bondi, compete for a ten thousand dollar scholarship.

Fast-paced and enjoyable!
The classic puzzle mystery! I still remember my 5th grade teacher reading The Westing Game to the class. I was completely riveted and it continues to be one of my favorite chapter books of all time. Mr. Westing, an eccentric millionaire writes his will as a game. The named beneficiaries must discover who murdered him in order to inherit his fortune. “Players” are separated into teams with clues. This unusual mystery kept my son on the edge of his seat, with its host of curious characters and surprising plot twists. I love how this book requires listeners to pay attention to details, thus exercising kids’ reading comprehension skills.

Chasing Vermeer by Blue Balliet. (series) This book is a tour de force! In fact the whole series could be on this list of puzzle mysteries.

If they solve the mystery, he will return the painting. Illustrator Brett Helquist incorporates clues for the reader throughout the book’s illustrations.

The Mysterious Disappearance of Leon (I Mean Noel) by Ellen Raskin. The Westing Game gets so much credit, Raskin’s other books are often overlooked. As you can tell from the title, wordplay is a big part of the puzzles in this marvelous puzzle mystery for kids.

In this elaborate story, three friends band together in New York City to solve a cipher that connects their apartment building to a centuries-old mystery of how the city was conceived. This is a hefty, compelling book with stellar writing, and complex, well-rounded characters. Best for ages 10 and up.
The Mysterious Benedict Society (series) in an incredibly popular series. I find the plot hard to describe in just a sentence or two, there are so many puzzles and mysteries to be solved, but the story centers around 4 children who answer an advertisement for gifted children only to find themselves at the center of an elaborate adventure that puts all their mental strengths to the test.
The Blackthorn Key by Kevin Sands. There is some dark subject matter in this book but it is an incredibly suspenseful and action-packed read aloud for older kids. (On par with some of the darker imagery in the Harry Potter books). Christoper, an orphaned apprentice in 17th century London must solve a complex puzzle surrounding the murders of apothecaries. Despite the seriousness of the plot, the well-drawn characters provide some humor. Be sure to pick up the companion book, Mark of the Plague.
