Filming has wrapped on the second episode of Sherlock‘s new season.

Season 4 Episode 2 began filming in Cardiff on Monday 16 May and is directed by Nick Hurran, who previously helmed Season 3’s finale, ‘His Last Vow’ and Doctor Who‘s 50th anniversary special.

It was announced last month that Toby Jones (Dad’s Army, The Girl) would be “bringing to life one of Doyle’s finest villains” in the story.

His character was recently confirmed as Culverton Smith, who originally appeared in ‘The Adventure of the Dying Detective’, a short story written by Sir Arthur Conan Doyle in 1913.

The episode also guest stars Sian Brooke (Dinotopia), who played Ophelia opposite Benedict Cumberbatch in Hamlet on stage in London last year.

Season 4’s finale will begin filming soon, directed by Benjamin Caron (Wallander, My Mad Fat Diary, Skins). The episode will be jointly written by Steven Moffat and Mark Gatiss.
