In a brief interview with Entertainment Weekly prior to a SXSW panel appearance Monday, Moffat confirmed rampant rumors that this winter’s special episode of Sherlock will be taking place in Victorian England. If that sounds like a plot from Moffat’s other show, Doctor Who, it’s only because creators Moffat and Mark Gatiss have decided to return their characters to their roots.
Members of the Sherlock fandom have been suspecting this might be the case ever since set photos surfaced in January of Cumberbatch and Watson in period Victorian costume.
The #Setlock photos caused lots of speculation about whether the special would be related to the sparse three-episode run of Sherlock‘s regular fourth season, but Moffat told EW the special was “kind of in its own little bubble.” That means it will be an independent, alternate universe story and won’t be tied to the narrative of season 4, which should premiere in early 2016. The special episode is expected to air in December.
