Game of Thrones star Rose Leslie has been cast in the upcoming two-part Luther special.
Laura Haddock and Darren Boyd will also join Idris Elba in the episodes that are set to air on BBC One this autumn.
In the two-part special Elba's DCI John Luther will be "pitted against his most chilling adversary yet, haunted by the ghosts of his past and hell-bent on retribution."
Dermot Crowley (DSU Martin Schenk) and Michael Smiley (Benny Silver) will reprise their roles though it is not yet known whether Ruth Wilson will return as Alice Morgan.
