The escape room company Time Run is creating the experience. Sherlock creators Steven Moffat and Mark Gatiss and the show's executive producer Sue Vertue were approached by Time Run with the idea, and currently work as consultants for it. It's been in the works for more than a year.
"It fits Sherlock," Moffat told BuzzFeed News. "Sherlock in the original stories are little puzzles, that's what they are. So it is a good match for us, and it would feel properly like the show."
Here's the concept of the game: Sherlock (Benedict Cumberbatch) is out of action. Fans of the show will be able to step into his shoes and solve problems against the clock in teams of four or five players, in various rooms that you will recognise from the show. The 90-minute experience, spread over 17,000 square feet, will feature specifically made video and audio of characters from the show, with their lines written by Moffat and Gatiss. Tickets will be available for £54.
"It's what you want to do when you originally read the stories: be Sherlock, or certainly try and make deductions," Gatiss told BuzzFeed News. "And of course in real life you rarely get to do that, so it's a chance to do that."
