Sherlock: Trailer | first look at series 4 - BBC One

This looks very different than the past three seasons of *Sherlock*. Almost looks like a globetrotting espionage thriller. As a huge fan of the show I will definitely be in my seat for this the day it airs but I'm hoping they'll still allow Sherlock and John to solve some cases - in the midst of all these huge overarching conspiracies that seem to be unfolding.
