Place the suspects, reveal the killer! These visually appealing, addictive puzzles drop solvers into immersive mini murder mysteries, combining features of classic Japanese-style logic puzzles like sudoku with the storytelling of classic grid logic problems. Each Murdoku grid is its own unique crime scene in which every detail is important: rooms, furniture, plants, animals, and most importantly, the suspects. Using the clues, you must find each suspect's location to reveal the killer. This time, though, there's a twist: you've stumbled upon a time portal that's brought you to the past. You'll visit the Stone Age, medieval times, the Old West, ancient Egypt, and the Golden Age of Piracy on your way back to your own time. Each era has its own flavor, but one thing is always true: there are murders to solve. Are you up for the challenge?","forthcoming":false,"isbn13":"9781454961802","publication_date":"20260519","publisher":"Union Square &amp; Co.","slug":"murdoku-volume-2-back-in-time","subtitle":"80 Murder Mystery Logic Puzzles","title":"Murdoku Volume 2: Back in Time"},"discovery":{"categories":{"all":[{"bisac_code":"YAN021010","confidence_band":"medium","label":"Puzzles & Word Games","score":0.7584,"source":"bisac_hint_model"},{"bisac_code":"FIC022100","confidence_band":"medium","label":"Amateur Sleuths","score":0.7444,"source":"bisac_hint_model"},{"bisac_code":"FIC022070","confidence_band":"medium","label":"Cozy Mysteries","score":0.7432,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"YAN021010","confidence_band":"medium","label":"Puzzles & Word Games","score":0.7584,"source":"bisac_hint_model"},{"bisac_code":"FIC022100","confidence_band":"medium","label":"Amateur Sleuths","score":0.7444,"source":"bisac_hint_model"},{"bisac_code":"FIC022070","confidence_band":"medium","label":"Cozy Mysteries","score":0.7432,"source":"bisac_hint_model"}],"publisher":[{"bisac_code":"GAM005000","confidence_band":"high","label":"Brain Teasers & Puzzles","score":1,"source":"onix_publisher_code"},{"bisac_code":"GAM007000","confidence_band":"high","label":"Puzzles","score":1,"source":"onix_publisher_code"},{"bisac_code":"GAM017000","confidence_band":"high","label":"Sudoku","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"Puzzles & Word Games","score":0.7584,"slug":"puzzles-word-games"},{"label":"Amateur Sleuths","score":0.7444,"slug":"amateur-sleuths"},{"label":"Cozy Mysteries","score":0.7432,"slug":"cozy-mysteries"}],"reader_fit":["Good for fans of logic puzzles and murder mysteries","Good for readers interested in time travel and historical settings"],"related_lists":[],"series":null,"similar_books":[{"authors":["Manuel Garand"],"book_id":"9781454961796","cover_image_url":"https://img.bookfrontier.com/9781454961796.jpg?v=20260529T161654Z%3A2026-05-29T17%3A17%3A38Z","score":26.2253,"title":"Murdoku","url":"https://bookfrontier.com/books/9781454961796"},{"authors":["G.
