A brand new trailer for the anticipated return of Sherlock has hit the web, and it plays up the social media frenzy surrounding Sherlock Holmes' (Benedict Cumberbatch) return from the dead.

"Oh. My. God!" exclaims a Sherlock fan after her phone buzzes to life.

Various Twitter hashtags take over the screen: #SherlockIsAlive!, #SherlockIsNotDead and #SherlockLives are among the most popular ones. (Talk about being meta.)

In August, the first trailer touting the return of the British series -- which plays on PBS Masterpiece in the U.S. -- debuted, focusing on various characters' reactions to learning of Sherlock's faked death. This one goes a step further, opening with John Watson (Martin Freeman) visiting Sherlock's grave and later likely coming face-to-face with the news.

Watch the preview below.

Sherlock returns Sunday, Jan. 19 on PBS Masterpiece.
