Finally, there is some news about the long-awaited fourth season of Sherlock. Creator Mark Gatiss is already working on it. Entertainment Weekly reports Gatiss has just finished writing Sherlock season four, episode one, and while he is not spilling secrets, he is dropping clues.

The third season of Sherlock aired on PBS in early 2014. The long hiatus, which sometimes feels like a cancellation, will be broken up by the Victorian special episode, Sherlock: The Abominable Bride, starring Benedict Cumberbatch and Martin Freeman. The stand-alone airs in both the US and UK on January 1.

From EW:

The third season of Sherlock screened back at the start of 2014 and ended with the seeming return of Sherlock Holmes’ archenemy Moriarty, played by Spectre star Andrew Scott. Can Gatiss say anything else about the upcoming season of the show, which is set to start shooting later next year? He can! “Well, it’s some more adventures. Ha ha!” chuckles the writer. “All I can say is, this is a major, life-changing series for the regulars. The repercussions of Moriarty’s apparent return are far-reaching. It’s very big stuff.”

Season four of Sherlock is set to start production in April, 2016. In case you missed it, check out the latest trailer for Sherlock: the Abominable Bride.
