SHERLOCK HOLMES ESCAPE BOOK: LONDON WATERWORKS (AMMONITE/PB)

You are Sherlock Holmes, at home at 221b Baker Street, when a mysterious letter is posted through your door. What is the meaning of the message cut from newsprint? Is there a clue hidden in the letters? Could there be more to discover in the fog-bound alleys of London town? This ingenious new series is a spin on the current urban craze for 'Escape Rooms'. Visual clues are hidden among the intriguing illustrations; fiendish riddles, logic puzzles, and timed challenges unlock hidden doors and reveal the direction of travel; and mathematical problems provide the codes required to follow the correct path. There are maps and mazes to explore; references to the original Sherlock Holmes adventures to unravel; and a code-wheel that holds the key to unlocking the next page towards your escape.
