An image of a forthcoming Sherlock episode, was released on the internet late last night.
As reported by the BBC, it appears to be set in Victorian London. And look at Dr Watson's wonderful moustache! So majestic! So elegant!
It's a lot more groomed compared to the last series (above right).
There's not much detail about the new episode, but that might change. Executive producers Steven Moffat, Sue Vertue and actor Rupert Graves are due to appear on a panel to talk about the show at the San Diego Comic Con later today.
