Watch the Very Dark and Foreboding Trailer for ‘Sherlock’ Season 4


Sherlock‘s upcoming fourth season will be its darkest and most action-packed yet, if this new teaser trailer is any indication.

The trailer opens with a flickering image of Moriarty (Andrew Scott) before Sherlock (Benedict Cumberbatch) intones in voiceover, “Something’s coming. Maybe it’s Moriarty, maybe it’s not. But something’s coming.”

There’s not much of the show’s signature whimsy in this very dark (literally and figuratively) teaser, which is packed full of helicopters, snipers, fiery explosions, and a procession of very creepy nurses. “Everyone they know is under threat,” the trailer portends. (Don’t worry, though; co-creator Mark Gatis promised Deadline there will still be laughter in Season 4.) We also get a glimpse of Season 4’s new villain, played by the excellent Toby Jones.

Season 4 is set to air sometime in 2017.
