A little while back, we bought you news of the resurrection of Sherlock. Kind of.

In a cryptic video, they said that something Sherlock-related is going to be happening this year, although Moffat was at pains to point out that it was “not a new episode, and not a new series, and not a film… but an actual new adventure – a proper one, involving the people that you’d expect to be involved in a Sherlock adventure…”

A link took you to thegameisnow.com, whereupon sign-up, another video awaited, this time with Gatiss and Benedict Cumberbatch reprising their roles as the brothers Holmes.

Now there’s a new video, and confirmation of what the event is.

An interactive game.

This is what the site said:

You’ve always known you could. You’ve seen the show. You’ve read the stories. “It’s not so hard,” you said to yourself. “I can do it.” Well, now’s your chance.

Sherlock: The Game Is Now is the only official Sherlock Escape Game, a 90 minute immersive experience for teams of 4-6 people.

Don your deerstalker and dive into an all-new mystery, penned by Time Run, renowned escape room pioneers, and series creators Steven Moffat and Mark Gatiss. Well then: what are you waiting for?

Here’s the latest video:

And there’s a story:

London needs Sherlock: unfortunately, it has you.

Sherlock is absent. Where? Oh, who knows. As a rash of break-ins ripple across the capital, one thing is clear: his brilliance is required.

Mycroft Holmes has put out the call. The Network seeks recruits: volunteers with sharp eyes, keen wits and a hunger for adventure. Can you step into the shoes of the legendary detective? Good luck: The Game Is Now.
