PBS Masterpiece has finally released a glimpse at the upcoming season of hit BBC show Sherlock.
The teaser remains mysterious about a lot, including exactly which Arthur Conan Doyle stories the fourth season will take on, but does seem to feature a brilliant detective that is worse for the wear and undoubtedly battling some demons. The teaser also offers a glimpse at previously announced new villain, Toby Jones.
The new season will premiere sometime in 2017. Watch the teaser below.
