Book excerpt: This is the second title in a series of Sherlock Holmes Escape Books: a unique, new form of puzzle books, in which the reader must solve the puzzles to escape the pages. Inspired by the urban craze for escape rooms, where players tackle challenges while trapped in a locked room, this is an escape room in the form of a locked book: filled with codes, ciphers, riddles and red herrings, plus an ingenious Hieroglyphic Code Wheel set into the cover. Taking on the role of Sherlock Holmes, in this new adventure readers find themselves trapped with Watson in the Enlightenment Gallery of the British Museum after a curator collapses in the Egyptian Collection. With King George V due to arrive at the nearby tube station, and rumors of an anarchist plot, Holmes and Watson must find their way through the museum, and fathom the involvement of both Mycroft and Colonel Sebastian Moran, if they are to win their freedom and save the day.
