Here's the first officially released promo photo from Series 4 - Sherlock and a (potentially familiar) furry friend!
Congratulations to #BenedictCumberbatch for winning Best TV Detective at the @OfficialNTAs for #Sherlock!
Sherlock returns in the UK on BBC One and USA on PBS on January 1 2017.
Airdates for other countries are TBC.
And that's a VERY intriguing image.
