It turns out there's still "unfinished business" for Idris Elba's John Luther: four new episodes of the show are coming to BBC One.
Announcing the return of the award-winning crime drama to Digital Spy, writer Neil Cross said: "Now what? It's a question Idris and I get asked a lot...
"It can't be over, can it? There's so much we don't know. So much unfinished business. The thing is, we've been asking ourselves the same question."
Teasing more, he added: "I'm scared of the monsters. The face at the window. The hand under the bed. The shadow at the end of the street.
"Who's going to stop them, if not John Luther?"
Speaking about his return to detective work, Idris Elba said: "Neil, the BBC and I have been talking about a further season and I am thrilled that we have been able to bring it all together.
"I look forward to putting the coat back on."
Piers Wenger, controller of BBC Drama, promised "big surprises" for the "utterly heart-stopping and unmissable fifth series".
While executive producer Hilary Salmon added that BBC Studios "will be pulling out all the stops to make the show bigger, bolder and of course more scary than ever".
