The first episode of series six of crime drama Shetland tonight at 9pm on BBC One.

The series was partly shot on the back road between Largs and Greenock during the summer, and past seasons have also been filmed in the area.

The programme stars Douglas Henshall as DI Jimmy Perez, who investigates crime on remote Shetland.

Filming for a future seventh series of the show is currently underway.
