This Book Contains a Crime. Puzzle Mysteries Collection
When a strange fantasy novel appears in the secret reading club of four friends, something doesn’t add up. The author died just days after publication — and the initials of the book’s chapters seem to spell out a desperate message: someone was trying to warn the world about a murder. To uncover the truth, the boys must decode hidden clues scattered across the novel’s pages, follow a trail of literary puzzles, and investigate the mysterious world of editors, manuscripts, and rival ambitions. Because this time the crime isn’t just inside the story — it’s hidden inside the book itself.
This Book Contains a Crime is part of the Puzzle Mysteries series, a highly engaging middle-grade collection (age 10+), created by a remarkable group of acclaimed Italian authors from the Book on a Tree collective. Each stand-alone novel is a brilliantly constructed interactive puzzle that reinvents the classic whodunit with fresh, contemporary twists. With no supernatural shortcuts, every mystery is solved through logic, deduction, and sharp observation. Readers are treated as real detectives, invited to gather clues, untangle deceptions, and solve the case alongside unconventional young protagonists. From gothic Alpine boarding schools and isolated islands to luxury trains and high-pressure contemporary concerts, each book offers a distinctive setting and a fresh angle on the genre. In this series, every clue matters — and every reader becomes the detective.
