Greenock-born actor Martin Compston will return as detective sergeant Steve Arnott and Nottingham's Vicky McClure will continue as detective inspector Kate Fleming.

Hide AdThe AC-12 trio has always come up against opposition and this season will be no different, with Glasgow’s Kelly Macdonald joining as detective chief inspector Joanne Davidson.
Macdonald, whose previous work includes Trainspotting, The Victim and Harry Potter and the Deathly Hallows, has received high praise for her contributions.
Her character will be the senior investigating officer of an unsolved murder and Mercurio recently described her as “the most enigmatic adversary AC-12 has ever faced”.
Fans were given a sneak peek of Macdonald in action when Mercurio posted a picture of her sitting across from the AC-12 team in the interrogation room.

Season one, which aired in 2012, only had five episodes.
Who is H?
Speaking on BBC Breakfast, McClure refused to be drawn on the identity of H.
Co-presenter Dan Walker asked: "I expect you to fob me off when I ask this as per usual but do we get any nearer to finding H?"
McClure responded: "I think the connection has gone."
She added: "I’m not saying anything."
Will there be a season 7?
Over 13.5 million people have seen the sixth and last episode of season five on 5 May 2019 - more than any other episode in the series.
