Fan of Sherlock Holmes? Love exploring London? Have I got the game for you!

For some time now Hiddencity have been leading teams of intrepid explorers around London, York, Manchester and Brighton. The task is simple: solve a set of cryptic clues and you just might find your way to the end of the trail. I can’t promise that you’ll emerge victorious (you’ll be competing against other teams and making every legal attempt to upset their chances of winning) but I can promise you that you’ll see hidden parts of the city that you never even knew existed.

The best part of it is that you’ll spend an afternoon with friends laughing and showing off your investigative and general knowledge skills and it will be a day you will never forget.

So what is Moriarty’s Game? The team at HiddenCity promise that even Sherlock Holmes himself would be challenged by this one. Inspired by the Sherlock Holmes stories, this adventure will run from 2 December 2015 to 31 March 2016 and booking opens today.

In this adventure, you will be challenged to find Moriarty’s safehouse. You’ll get to explore exhibitions celebrating contemporary architecture, drink in Georgian public houses, scrutinise 15th century art in a Mayfair townhouse and solve a host of cryptic challenges from the master of misdirection himself.

Up for the challenge? Find a team of up to four people and visit the Moriarty's Game page to book.
