★ The Latest Trend in Interactive Mystery Fiction.
A brand-new entry in the wildly popular genre sweeping the US and Europe. It is the perfect reason to put down your phone and dive into the thrill of paper-based detective work. It’s an ideal brain workout for adults and teens alike.

A killer is running through the city. The map knows where. Do you?
CrimeMaps is a detective logic puzzle book for adults unlike any other: every case hands you an illustrated city map, a trail of movements, and a handful of witness statements, camera sightings and impossible clocks. Your job? Reconstruct the killer’s escape route, step by step, and deduce the one place they’re hiding.

No trivia. No word searches. Just pure deduction — the same satisfying logic of Sudoku and escape rooms, rebuilt as a murder mystery brain game you solve with a pencil on a beautiful map.

Chase killers across the world’s greatest cities. Track a poisoner through the ramen alleys of Tokyo. Corner a strangler between the minarets of Istanbul. From Barcelona to Rome, London, Paris and New York, every city brings new streets, new transports — metro, ferry, taxi, bike — and new ways for a killer to disappear.

Difficulty that grows with you. Cases climb from friendly warm-ups to true Mastermind challenges, including double-killer cases where two accomplices move through the city at once — and only cross-examining both trails will break their pact. Every single puzzle is logically airtight: one unique solution, no guessing, ever, with full step-by-step solutions explained at the back.

Perfect for fans of murder mystery puzzle books, logic grid puzzles, detective games and escape room puzzles — and a standout gift for puzzle lovers, true crime fans and armchair detectives who think they’d catch the killer.

Open the map. Follow the trail. Find them.
