The Cypher Files
THE ULTIMATE GIFT FOR WANNABE SPIES: AN INTERACTIVE PUZZLE BOOK FROM THE CREATOR OF THE BESTSELLING CULT PHENOMENON, JOURNAL 29! In this brain-bending interactive game, you'll solve puzzles on every page, and obtain keys to move forward by submitting answers online. To solve each puzzle, you'll need to think outside the book. You are an agent of CY.P.H.E.R., the secret international agency working on 'unsolvable' code-based cases. Called upon to investigate cryptic clues discovered in the wake of a series of mysterious disappearances, the clock is ticking to crack the codes before it's too late. To escape this book, you must write, draw, search, fold and cut pages, explore virtual escape rooms and think laterally to identify the perpetrator and solve the mystery. All you need to play is a pencil, a pair of scissors, an internet connection, and a curious mind.
The Escape Book 2
Will you get to the Orwellians before the Wanstein Club get to you? The clock is ticking… Based on the global phenomenon of Escape Rooms, and following on from the international bestseller The Escape Book by Ivan Tapia, this book puts your ingenuity, wit and perseverance to the test with even more fiendish challenges, puzzles, and enigmas that you must solve to thwart the sinister Wanstein Club. Investigative journalist Candela Fuertes is at rock bottom: her fight against Castian Warnes, the head of the powerful and sinister Wanstein Club, has undermined her credibility as a journalist, and meanwhile she suspects Warnes is behind the car accident that put her boss in hospital. Corroded by the thirst for revenge, she decides to turn to the only people who can help her in a cause that seems already lost: the Orwellians, a group of hackers hell bent on revealing the secrets of the rich and famous. In order to get to the Orwellians, you and Candela must follow their trail all over London. The chapters of the book are jumbled up, and to know where to continue reading, you must solve the puzzles, optical illusions, conundrums and anagrams that you find. Each time you solve a puzzle, the number you arrive at will indicate the page from which you can continue the story.
