The BBC and PBS both announced today, July 2 2014, that a fourth season of Sherlock is in the works, along with a stand-alone special which will air as a prelude to the fourth season.
In a statement to Press today, executive producer Steen 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.”
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!”
Production on the special will begin January 2015, with season 4 kicking off a little later in the year.
Stay tuned for premiere dates!
