Idris Elba's maverick detective John Luther is heading back to TV with two special episodes set for BBC One next year.
The hit show, which is about to be remade in the United States, stars The Wire actor as the troubled police officer and starts filming in London in March.
Its writer, Neil Cross, said: "Ever since we said goodbye to John Luther on Southwark Bridge, there's hardly been a minute when I didn't wonder what happened next. So I decided to find out. We're putting the band back together; Luther is coming back where he belongs. Back to the BBC. Back to London. And back to work."
The show is part of a raft of new commissions announced today by the BBC, including another series for Jane Campion's drama Top Of The Lake.
Harry and Jack Williams, who wrote current hit The Missing, will return with One Of Us, which is described as "a modern-day parable" and examines the aftermath of a double murder in the Highlands of Scotland.
There is also a new police show, called Cuffs, set in Brighton and an adaptation of Joseph Conrad's anarchist tale The Secret Agent by Tony Marchant.
Marchant, who wrote Iraq War drama The Mark Of Cain, said: "Conrad's depiction of 19th century terrorists committed to the destruction of the West with a suicide bomber in their midst was not only prophetic but is undeniably contemporary and compelling. Equally it is a heart-breaking story of a family caught up in the political machinations of a world in ferment."
There will also be an English-language version of Israeli drama The A Word about a family coming to terms with their son being diagnosed with autism.
BBC director-general Tony Hall said: "Drama is something that is in the lifeblood of this country and in the DNA of the BBC too. We are making some fantastic dramas at the moment and I am looking forward to some more stand-out successes next year."
