Suggesting that viewers are in for something creepier than previous installments of Sherlock, Moffat said: “Ghost stories work better in a Victorian setting. This strand of Doyle original stories that are creepy and scary, and the chillers, we haven’t done much with in the modern show. But putting it back into Victorian times, you think it’s a chance to do a ghost story, really – a creepy, scary one.”
The stage is set. The curtain rises. We are ready to begin.
