Credit: BBCSherlock is to return to screens for a special episode before a series of three new episodes, it has been confirmed today by the BBC.
The last series saw Sherlock's life turned upside down, as he returned from the dead and seemed to meet his match.
Talking about the series return, co-creator, writer and executive producer Steven Moffat said: "A special, plus a new series of three episodes - it's a record-breaking run! 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 and executive producer Mark Gatiss added: “Series Four! At last! It's always special to return to Sherlock but this time it's even more special as we're doing... a Special! Not only THAT, we'll then be shooting three more episodes which will take Sherlock and John Watson into deeper and darker water than ever before. The whole Sherlock team are terrifically excited to return for four new adventures. The Game is on - again!"
Shooting on the special doesn't begin until January 2015, and the series will then go on shoot the three episodes later the same year.
