In anticipation for the long-awaited Sherlock special, which throws the modernized Sherlock back into the Victorian era with a plot line set in 1895, the BBC has released vintage-style teaser posters promising "friendship, adventure," and "murder" in "Sherlock: The Abominable Bride." 

In conjunction with the posters, a 15-second teaser trailer was also released, featuring Sherlock and Watson donning bowlers and (in the case of Watson) curlicued mustaches, as well as a mysterious, ghostly-looking bride-to-be.

As Comic Book Resources notes, the teasers are a throwback to the Sherlock films of the 1930s and 1940s, which starred Basil Rathbone as Sherlock and Nigel Bruce as Watson. The duo starred in 14 Sherlock-centric films together.

Starring Benedict Cumberbatch and Martin Freeman as Sherlock Holmes and John Watson, the New Years Day special will also feature guest appearances by Una Stubbs, Louise Brealey, Rupert Graves and Amanda Abbington.

Here is the official synopsis for the Sherlock special:

"We've been here before — but what if this wasn't the modern day but the late Victorian period? What if the world's most famous consulting detective and his best friend lived in a Baker Street of steam trains, hansom cabs, top hats and frock-coats?  

Welcome to Sherlock in 1895! Some things, though, remain reassuringly the same. Friendship, adventure and especially, MURDER ...

Why is Thomas Ricoletti a little surprised to see his wife dressed in her old wedding gown? Because, just a few hours before, she took her own life ...

Mrs. Ricoletti's ghost now appears to be prowling the streets with an unslakeable thirst for revenge. From fog-shrouded Limehouse to the bowels of a ruined church, Holmes, Watson and their friends must use all their cunning to combat an enemy seemingly from beyond the grave and the final, shocking truth about ... the Abominable Bride!"

Check out some of the teaser posters below for the Sherlock Victorian-era special, premiering Jan. 1 on PBS and BBC One, as well as in select theaters for limited release.
