Mark Gatiss on the 'dark' return of Sherlock!
It's the same combination of laughs and terror, but it has a darker edge to it. Toby Jones is the new villain and he's skin-crawlingly horrible.
For fans of Sherlock, the wait is nearly over as the brilliant Benedict Cumberbatch and Martin Freeman will reunite on screen for a special on New Year's Day.
Joining them in the gripping drama is actor and co-creator of the show, Mark Gatiss, who plays Sherlock's brother Mycroft.
He joined us today to give us a sneak preview of what's promised to be the most compelling series yet!
