Sherlock Season 4: Show Creators Mark Gatiss and Steven Moffat Teased 'Darker' and 'Devastating' Season After Three Emmy Wins

Sherlock team is riding high on their success after winning three Emmys in the recently concluded 66th Primetime Emmy Awards in Los Angeles.

Benedict Cumberbatch (Sherlock Holmes) and Martin Freeman (Dr John Watson) won best actor and best supporting actor in a mini-series, while Steven Moffat got an Emmy for best writing in a mini-series for the final episode of Sherlock's third season.

Show creators Mark Gatiss and Moffat discussed their Emmy wins backstage, teased about the upcoming Sherlock season and dropped a "devastating" scoop.

They revealed that Sherlock Season Four is going to be 'darker' and more 'devastating' than ever before, reported Entertaintment Weekly.

Sherlock writer Gatiss teased a little more about Season 4 and said, "We're going to try to take it somewhere we've never been before — and I don't mean outer space."

"It will be challenging place to go. We always start with a re-introduction that builds toward a darker climax — we might just be going darker [from the outset]. We got a very, very good set of ideas."

"We've practically reduced our cast to tears telling them the plan ... we're probably more excited that we've ever been about Sherlock," Moffat revealed.

Moffat also cleared the air around the Sherlock-obsessed social site Tumblr.

He said, "We have to stay away from it, particularly me. My friends keep saying 'don't go on Tumblr, they're tremendously cross.'"

Moffat revealed that he didn't bet on Sherlock to win at Emmys.

He said, "I didn't think we'd win anything," he said. "I'm a bit worried about rewinding and seeing my speech ... we were just starting to think that phase [of getting awards attention] was dying down ... hopefully more people will watch it."
