Karen Pirie Season 2 Plot
Karen Pirie Season 2 is based on Val McDermid’s acclaimed novel A Darker Domain and follows DI Karen Pirie as she reopens a haunting cold case. In 1984, heiress Catriona Grant and her son Adam were kidnapped at gunpoint in Fife and never seen again. Despite a flurry of ransom notes and public outcry, the case went cold—until now. The recent discovery of a man’s body linked to the original crime brings Karen back into the spotlight, alongside her team, DC Jason ‘Mint’ Murray and DS Phil Parhatka. As political grudges surface and painful secrets unravel, Karen must navigate high-profile pressure from Sir Broderick Grant, Catriona’s father. The deeper she digs, the more she realizes that the past refuses to stay buried. What follows is a race against time, justice, and buried guilt.
