A new trailer has been released for Sherlock season 4, teasing some dark turns ahead in the fourth chapter of the fantastic series.
Benedict Cumberbatch continues on as the famous detective, who is this time facing quite the deadly new foe, Culverton Smith (Toby Jones). “What’s the very worst thing you can do to your very best friends?” Smith asks. “Tell them your darkest secret.” Intriguing.

On a lighter note, the next season will also see Watson (Martin Freeman) and his wife Mary (Amanda Abbington) preparing for their first child.
Sherlock season 4 begins January 1, 2017 on MASTERPIECE on PBS.
