Benedict Cumberbatch and Martin Freeman will reunite as the famed duo in the holiday special of 'Sherlock'. The pair is said to do battle with an enemy from beyond the grave. 

Comicbook.com reports that Holmes and Watson will be in old Victorian England. From the looks of the trailer, the duo are to battle forces with the supernatural as Thomas Ricoletti sees his wife dressed in her old wedding gown just a few hours after she killed herself. 

CNET reports that the 90-minute holiday special will be a "one-off" episode and will have nothing to do with the upcoming episodes in the fourth season of 'Sherlock'.

The special episode, called "The Abominable Bride" tells of a ghoulish woman's quest for revenge. Holmes and Watson's supernatural adventure will be set in the 1890's, which is original timeframe of the classic Sherlock Holmes series.

According to the show's creator, Steven Moffat, said that old Victorian England was the perfect setting for the supernatural episode, as there was nothing as eerie and unsettling as the fog-laden corners and alleyways of old London. 

The entire experience, he added was something new as 'Sherlock' happens to take place in modern times. He further explains that changing the setting and time period of the show was both a "challenging and fun experiment". 

This is to be the last time that the show will see Holmes and Watson as timelords, reports BBC. Writer, Mark Gatiss, explains that the fourth season of the popular show will still star Cumberbatch and Freeman despite the pair's busy schedules in Hollywood. 

The fourth season is currently still in production. There is already much speculation that the future episodes of 'Sherlock' will take on a darker tone, but that remains to be seen.

Meanwhile, the one-off holiday episode of 'Sherlock' will premiere in theaters and will take on 'Star Wars: The Force Awakens'. Writer Sue Vertue is confident that 'Sherlock' will be a strong contender against the mega-franchise that is set to dominate box offices worldwide.

"Well when we were filming it we hadn't necessarily thought about putting it on in cinemas at the time, but we were talking about it." 

And we just thought it would be an exciting event to see and we love seeing it with fans, so we want to go and see it in the cinema, I have to say." Vertue said.

"Sherlock: The Abominable Bride" premieres on TV and in cinemas for one night only on 1st January 2016.
