Ten Little Tenants. Puzzle Mysteries Collection
The city is slipping into darkness. Blackouts spread. Tremors shake the streets. And in the middle of this growing unease, a murder is committed in Ash Building, a grim apartment block standing alone on the edge of town. The case is assigned to Lucius Asgren, the most brilliant detective on the force — a legend known for solving the impossible. But this investigation is unlike anything he has faced before. The tenants are bizarre, secretive, and deeply suspicious, and as Asgren begins to question them, they start dying one by one. What begins as a single murder turns into a nightmare spiral of death, hidden identities, and mounting dread. In a building where every door conceals a secret, Asgren must untangle the most infernal mystery of his career — before the case consumes him too.
Ten Little Tenants 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.
