The game is on — again!, BBC One tweeted this afternoon. That was following clues it left Monday night alerting Sherlock fans that a surprise was in store for today. In the first missive, the channel — which had changed its handle to “Sherlock – #221back” for the occasion — posted a GIF of Andrew Scott as Moriarty from the last episode of Season 3, and the question, “Did you miss me?” An hour later, BBC One wrote, “It’s all gone dark… Something’s coming… Or someone. Details at 2.21pm tomorrow.” And now we’ve solved the mystery. The BBC has confirmed the sleuthing drama will return for a special, followed by a series of three new episodes. Shooting on the special will start in January 2015, with the series shooting later next year. “We’re ready to unleash the most shocking and surprising series of #Sherlock yet. The only thing is to expect is the unexpected…,” said BBC One today. A fourth season has unofficially been afoot for some time, but dates have never been specified — a lot of juggling is necessary given the big screen demands on stars Benedict Cumberbatch and Martin Freeman. Today’s confirmation follows reports on Sunday that the high-functioning sociopath and sidekick/best pal Dr John Watson would be back for a special in 2015. Freeman told The Telegraph a period of filming looked “pretty likely” in early 2015 and that he thought it “might be for next Christmas.” Either way, fans have had to wait long periods before to catch up with the characters, and their fervor has not abated. When Season 3 kicked off on BBC One and PBS in January this year after a two year hiatus, it was the series’ most-watched episode ever, on both sides of the Atlantic.

Of course, it’s far too early to say what’s coming, but we’re reasonably confident that the very next thing to happen to Sherlock and John, is the very last thing you’d expect…” Co-creator, writer, exec producer and co-star Mark Gatiss added that the three new eps will take Sherlock and John “into deeper and darker water than ever before.”

The stunt used by the BBC last night to tease today’s announcement is another sly means by which the network has doled out clues in the past. Last November, it announced the UK airdate for the return of the detective drama by flower arrangement in the window of a hearse that made the rounds of some of Sherlock‘s London shooting locations. The vehicle was a nod to the first episode of last season, The Empty Hearse. Twitter, natch, went wild.

I;d like it to get a lot darker because the actors can handle it with ease.
