The new interactive puzzle book from the creator of the bestselling cult phenomenon Journal 29

The Cypher Files is an utterly unique reading experience. 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.
