BBC One Sets Premiere Date For 'Sherlock' Season 4 – TVWise

The fourth season of Sherlock will premiere on BBC One on New Year’s Day (Sunday January 1st) at 8:30pm, it has been announced.
Based on the works of Sir Arthur Conan Doyle, Sherlock was developed for television by Steven Moffat and Mark Gatiss and is described as a modern take on the Holmes stories.
The drama series focusses on Holmes and Watson as they consult on cases, usually for the Metropolitan Police Service. Sherlock is produced by Hartswood Films and stars Benedict Cumberbatch, Martin Freeman, Mark Gatiss, Rupert Graves, Una Stubbs and Amanda Abbington.
