The transformation of Fast and Furious movies into a a rollercoaster makes horrible sense, and the Saw series obviously translates well into haunted houses, but what do you do when you want to make a visitor attraction out of Steven Moffat and Mark Gatiss’ Sherlock?

It seems like the BBC might have nailed it.

We have learned that discussions have happened, and may be rather advanced, for Sherlock spin-off escape rooms – or, at the very least, escape room singular.

An escape room is a kind of puzzle game – indeed, they’re sometimes called puzzle games – in which a group of players get locked into a room and have to find clues and solve puzzles in order to escape. They are tremendous fun, even addictive. They’re a bit Crystal Maze-y, but tend to be more integrated and less obstacle course-like.

There are several companies who specialise in designing these rooms and we understand that BBC Worldwide or their reps have engaged such a company, or companies, to do some work on a Sherlock room. The most obvious choice might be to base the experience on 221B Baker Street, or even (mild season four spoiler right here) Sherrinford from The Final Problem.

Maybe they’ll book Andrew Scott to record some scary Moriarty messages for in-room video screens, setting challenges, giving clues and taunting the players? Suffice to say, the match between “Sherlock” and “escape room” is a very good one.

There’s nothing official out there yet but we’ve got communications open with our source on this and will keep you posted should any more information come to light.
