The multi-award winning drama will return to BBC One, with Idris Elba reprising his role as DCI John Luther.
Details of the latest series are being kept under wraps, but there's no doubt that it will be full of scary surprises.
Writer Neil Cross said: "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. 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?"
