Filming is underway in Oldham and Manchester for eight new episodes in which their relationship will be sorely tested as both seek the same promotion to Detective Sergeant.
Amelia Bullmore reprises her role as plain-speaking D.C.I. Gill Murray who keeps control of Syndicate 9 and ensures the team delivers in spite of the pressures of modern day policing.
Additionally, Amelia (Di and Viv and Rose at the Hampstead Theatre and Craven for BBC Radio 4) will write four of the scripts for the new series. Former Coronation Street actor Lee Warburton will write two episodes with Emily Ballou (American Blackout, Case Histories) writing the remaining episodes.
Suranne, Lesley and Amelia will be joined in this new series by Danny Webb (Locke, Poirot, Lightfields) who takes on the role of family man D.C. Chris Crowley. Danny Miller (Emmerdale) returns to his role as D.S. Rob Waddington.
