Mark Bonnar’s Role in Line of Duty Series

Character Background and Arc

Mike Dryden entered the Line of Duty narrative during Series 2 as Deputy Chief Constable, positioned at Pelbury House. His initial involvement centred on leading the investigation into a botched ambush operation, though the character would prove to be far more morally complex than his rank suggested. Throughout his appearances, Dryden operated in the grey areas of police procedure, balancing official duties with questionable allegiances.

AC-12 investigators grew increasingly suspicious of Dryden’s activities, suspecting he harboured hidden motives connected to institutional corruption. The character’s trajectory saw him navigate the dangerous waters between lawful policing and corrupt practices, ultimately culminating in his arrest for involvement in covering up corrupt activities.

Return in Season 7

The announcement of Mark Bonnar’s return in Season 7 represents a significant moment for the series.

Bonnar joins a roster of returning cast members that includes Martin Compston as Steve Arnott, Vicky McClure as Kate Fleming, and Adrian Dunbar as Ted Hastings. New cast additions feature Tom Weston-Jones as DI Dominic Gough, alongside Laura Aikman, Amy-Leigh Hickman, Levi Brown, and David Calder.
