'Sherlock' Series 3 teaser: Sherlock Holmes lives and the whole world knows it

Sherlock Holmes ( Benedict Cumberbatch) isn't quite as dead as some seem to think he in on "Sherlock." In fact, a new teaser from the BBC shows that he's very much alive and the world is about to find out.

The quick 30 second clip is mostly to promote the hashtag #SherlockLives, which is a little familiar if you remember early advertising for "Agents of SHIELD."

Series 3 of "Sherlock" will begin January 14 on PBS.
