"Dr John Watson, meet Mr Sherlock Holmes.”
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!
Sherlock is written and created by Steven Moffat and Mark Gatiss, and inspired by the works of Sir Arthur Conan Doyle. Sherlock is produced by Sue Vertue and the executive producers are Beryl Vertue, Mark Gatiss and Steven Moffat for Hartswood Films, Bethan Jones for BBC Cymru Wales, and Rebecca Eaton for Masterpiece.
Sherlock, The Abominable Bride was commissioned by Charlotte Moore, Controller of BBC One, and Ben Stephenson, former Controller of BBC Drama Commissioning.
The episode will broadcast on BBC One on 1 January 2016.
