The third title in this ingenious series of Sherlock Holmes Escape Books, The Adventure of the Analytical Engine is an exhilarating combination of escape room, puzzle book and adventure story. Inspired by real-life escape rooms, where players tackle puzzles while trapped in a locked room, it is an escape room in the form of a locked book, filled with codes, ciphers, riddles and red herrings, and a clever Code Wheel set into the cover.
