Fans of the mystery BBC series are all in hot anticipation for the announced Christmas special which will portray the well known characters in a Victorian setting.

Details on the special has been scarce, but showrunner Steven Moffat gave fans a bit more to go on at the Television Critics Association's press tour event in Beverly Hills on Saturday.

"Sherlock is a little more polished," Moffat said of the title character. "He operates like a Victorian gentleman instead of a posh, rude man. He's a lot less brattish."

He also reveals that Watson will be seen as more uptight.

He also states that the era the two are represented in what mess up the continuity of the current show.

"We never bothered explaining what they were doing in modern London, so why bother explaining what they're doing in Victorian London, when that's where they're supposed to be?" Moffat stated.

"Ghost stories work better in a Victorian setting."

"And when, pray-tell, will we actually see this special? Well, the BBC has first dibs on airing Sherlock, as always. And British television tends to announce premiere dates rather close to a show airing, sometimes only a few weeks in advance (unlike in the U.S., where premiere dates - and accompanying network marketing campaigns - often start months in advance). So PBS Masterpiece is waiting for the BBC to announce. The is assumed to be a Christmas special, but Moffat has also previously said that it's not really," writes EW.

Season 4 of 'Sherlock' plans on shooting next spring and will feature 3 episodes.
