Discover the hilarious and action-packed first book in the Brixton Brothers series: The Case of the Case of Mistaken Identity by Mac Barnett — a clever, fast-paced mystery that turns a kid who just wants to finish his homework into America’s most unlikely detective!

Steve Brixton dreams of being a real detective like his heroes, the Bailey Brothers, whose books he’s read cover to cover. But when he heads to the library to grab a book for his social studies report, he accidentally checks out the wrong one — a mysterious volume packed with classified American secrets dating back to George Washington. Suddenly, everyone thinks Steve is a master spy: helicopter-rappelling librarians turn out to be secret agents, ninjas chase him through the stacks, and a criminal mastermind is after the book. To clear his name and survive, Steve has no choice but to solve the biggest mystery of all — while dodging danger, outsmarting villains, and proving he’s more detective than he ever imagined.

With witty humor, over-the-top action, clever twists, and fantastic illustrations by Adam Rex, Mac Barnett delivers a laugh-out-loud adventure that’s part homage to classic detective stories and part pure fun — perfect for readers who love a mix of mystery, comedy, and heart.

Ideal for middle-grade readers (ages 8–12) who enjoy humorous mysteries with smart, relatable heroes, fans of series like A to Z Mysteries, Encyclopedia Brown, or the 39 Clues but with more laughs and absurdity, kids who love detective stories full of gadgets, chases, and unexpected heroes, and anyone who appreciates clever writing and a story that keeps you guessing (and giggling) — great for quick, exciting reads or sharing with friends!
