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', in which participants are locked in rooms, and must solve the puzzles they find there to make good their escape.
Here, the book becomes the locked room, the pages become the path, and the reader can take on a challenge every bit as brain-teasing from the comfort of their own home.
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.
Solve the puzzles correctly to escape. Get them wrong, and you will find yourself further and further along the path to your own demise.
