Sherlock Season 4 Trailer Is Out And I Can’t Stop Screaming!

Edgy.

If Sherlock can be on the edge, you can be sure that the problem troubling him is not an easy one. And the trailer makes sure that every fan feels the tension in their belly because Sherlock seems genuinely troubled.

Who is the enemy? Moriarty? Some other new guy?

We do not know.

To compound the problems, Mrs. Hudson gets rude with Sherlock’s brother!

OMG OMG OMG!

CANNOT. WAIT. TILL. 2017.
