Sherlock Season 4 Trailer Sees a Troubled Cumber batch Deal With Demons and Secrets

Sherlock’s fourth season, starring Benedict Cumber batch in the titular role, is on its way next year – and BBC has now given us a new trailer. The show seems to be taking a darker turn than usual, as co-creator Steven Moffat had promised, and it begins with a line uttered in the teaser.

“The roads we walk have demons beneath, and yours have been waiting for a very long time,” a character speaks off-screen. The trailer then moves on to set up Toby Jones as the villain Culverton Smith, who will be appearing in the second episode of the season. Over a bunch of different shots, Jones lays out his agenda for Sherlock: “What’s the very worst thing you can do to your very best friends? Tell them your darkest secret.”

The new trailer closes with Sherlock uttering three words that you wouldn’t associate with him, which you can see in the video below.
