The BBC has bolstered the cast for the return of its island crime drama Shetland.
Brian Cox and Julie Graham will star in the murder mystery alongside Douglas Henshall in the six-part second season of the BBC One drama, which is currently filming in Scotland.
Based on the novels by Ann Cleeves, the new run will tell the three remaining stories – Raven Black, Blue Lightning and Dead Water – in three two-part (2×60′) episodes.
Raven Black is written by Gaby Chiappe, Blue Lightning by Richard Davidson and Dead Water by David Kane.
Shetland is executive produced by Christopher Aird for the BBC and Elaine Collins for ITV Studios. It is produced by Peter Gallagher.
