In the official Twitter account of "Sherlock," a new clip has recently surfaced for season 4. The new trailer suggests a darker season 4 of "Sherlock" is about to unfold next month. In the short clip, fans of "Sherlock" can see an animated image of detective Sherlock (Benedict Cumberbatch) and his sidekick, Dr. Watson (Martin Freeman) seated on a couch, with a serious face.

From our previous report, co-creator Mark Gatiss teased a creepy scene of Sherlock from episode 3 of "Sherlock" season 4. On his official Twitter account, Mark Gatiss shared a behind-the-scenes photo of Benedict Cumberbatch with a gloomy dark sky and a moon slightly peeking above him.

The newly released trailer and the previously teased photo seem to suggest a creepy season 4 of "Sherlock." Fans of the hit series can expect more mysteries when the show returns next month.

Furthermore, it is not the first time that the tagline "It's not a game anymore" on the new trailer has appeared. The show has already posted this line on its tweet last month when it posted the promo video for season 4. It seems that the show is putting emphasis on the said tag line. Fans of "Sherlock" can expect more intense plot for season 4 as the tagline and the new video teased how serious Sherlock is.

Meanwhile, creators Steven Moffat and Mark Gatiss have already revealed that the upcoming season will explore the themes of Thatcher, Smith and Sherrinford.

"Sherlock" season 4 will premiere on Jan. 1, 2017 on BBC.
