Sherlock Holmes (Benedict Cumberbatch, left) and John Watson (Martin Freeman, right) take on a new case in "Sherlock: The Abominable Bride," airing Friday at 9 p.m. EST on PBS. PBS

If New Year's Eve is for staying out late to bring in the new year, New Year's Day is about taking the day off to stay in and nurse that holiday hangover. Those staying in on Friday are in luck. The "Sherlock" holiday special, "The Abominable Bride," starring Benedict Cumberbatch as the titular Sherlock Holmes, will air Friday to kick 2016 off with a bang ... and a deerstalker cap.

"Sherlock: The Abominable Bride" will air at 9 p.m. EST Friday on PBS Masterpiece, which should be more than enough time for tired fans to wake up after sleeping off the previous night's New Year's festivities. The highly anticipated special sees Cumberbatch and Martin Freeman reprising their roles from the popular BBC series as the iconic detective and his loyal assistant, John Watson, respectively.

However, Friday's big mystery is going to look very different than the modern day adaptation of Sir Arthur Conan Doyle's "Sherlock Holmes." This time, according to the synopsis, Sherlock and Watson will be transported to Victorian England for the new case, the mysterious appearance of an apparition of a woman who committed suicide and seems to be on a revenge-inspired killing spree.

Watch the trailer for "The Abominable Bride" below:

The new (or, rather, old) setting means that Cumberbatch's Sherlock will be looking more like the literary original than ever before.

We’ve had the deerstalker [cap] in [the BBC] version but more as an ironic thing. It’s very different to show him in the full rig: The Inverness cape and the tweed and the pipe," "Sherlock" co-creator Mark Gatiss told USA Today.

Will Sherlock and Watson solve the new case? Fans will have to tune in to find out. "Sherlock: The Abominable Bride" airs Friday at 9 p.m. EST on PBS.
