ITV’s crime drama Karen Pirie brings Val McDermid’s detective novels to television, centred on a tenacious Scottish investigator portrayed by Lauren Lyle. The series follows DS—later DI—Karen Pirie as she unravels historic cases that have haunted communities for decades.
Adapted from McDermid’s Inspector Karen Pirie book series, the production arrived on ITV1 and ITVX with an ensemble combining established Scottish character actors and emerging talent. The narrative structure alternates between contemporary investigations and flashback sequences, requiring performers to portray characters across multiple timelines.
Two series have broadcast thus far, with the sophomore run arriving in 2024 after a three-year production interval. The programme sits alongside contemporaries such as the Cast of Shetland (TV Series) in ITV’s portfolio of northern-set crime dramas.

Who Is in the Full Cast of Karen Pirie?
The complete ensemble credits reveal a production built around dual timelines, with performers often playing both contemporary and historical versions of their characters.
Season 1 Personnel
The inaugural adaptation of The Distant Echo established the investigative unit alongside suspects in the 1996 Rosie Duff murder. Lauren Lyle anchored the programme as the eponymous detective, supported by Chris Jenks as her colleague DC Murray and Zach Wyatt as DS Parhatka. The victim, Rosie Duff, appeared in flashback sequences portrayed by Anna Russell-Martin.
Additional key figures included Gilly Gilchrist as DI Barney MacLennan, Stuart Bowman as Chief Superintendent Jimmy Lawson, and Daniel Portman—recognisable from Game of Thrones—as Colin Duff. The structure required younger performers including Buom Tihngang and Jhon Lumsden to portray student characters during the original 1996 timeline.
Between productions, Lyle’s character received promotion from Detective Sergeant to Detective Inspector, reflecting her experience within the fictional Police Scotland cold case unit.
Season 2 Expansion
The second series, drawing from A Darker Domain, introduced an entirely new case while retaining the core investigative team. According to Radio Times casting information, James Cosmo joined as Sir Broderick Grant, an oil billionaire whose daughter Cat—played by Julia Brown—was kidnapped in 1984. Frances Tomelty portrayed Lady Mary Grant, with younger versions of these characters played by Jamie Michie and Madeleine Worrall respectively.
New police personnel included Saskia Ashdown as DC Isla Stark, assigned from the E-crime division to observe Pirie’s methodology. The season also marked the introduction of Emer Kenny’s Dr River Wilde and Rakhee Thakrar’s Bel Richmond, a former podcaster assisting with the historical investigation.
Karen Pirie Season 2 Cast Changes
The sophomore run brought significant additions whilst maintaining continuity among the principal investigators. Casting details confirm that Lauren Lyle, Chris Jenks and Zach Wyatt all reprised their roles, alongside Steve John Shepherd as DCS Simon Lees.
Returning Characters
DI Pirie’s professional evolution formed a central narrative thread, with her increased rank bringing greater autonomy within the fictional police hierarchy. DC Murray and DS Parhatka continued as her immediate colleagues, preserving the established investigative dynamic despite the new case parameters.
Emer Kenny returned both as writer and performer, ensuring tonal consistency between series whilst expanding her on-screen role as forensic specialist Dr River Wilde.
New Entrants
The 1984 kidnapping narrative required performers capable of portraying characters across four decades of elapsed time. Mark Rowley appeared as the younger Mick Prentice, with Tom Mannion playing the contemporary version; similarly, Conor Berry and Tom Mannion shared the role of Andy Kerr. John Michie joined as Fergus Sinclair, father of Cat Grant’s child and former employee of the Grant industrial empire.
Season 2 presents a self-contained investigation; viewers require no familiarity with the Rosie Duff case to follow the Broderick Grant kidnapping storyline.

How Does the Cast Reflect Scottish Crime Drama Traditions?
The production continues ITV’s investment in Scottish-set crime fiction, utilising local performers including Kevin Mains, Gemma McElhinney and Barrie Hunter alongside international names. This approach mirrors casting strategies seen in the Cast of Shetland (TV Series), where regional authenticity takes precedence over star power.
St Andrews provides the primary location, with the university town’s distinct architecture featuring prominently. The ensemble reflects this specificity through accents and cultural references that distinguish it from generic British crime settings. Comparisons with the Happy Valley Cast reveal similar commitments to northern English and Scottish regional identity, though Karen Pirie maintains a distinctly Fife character.
The adaptation remains faithful to McDermid’s source material, with casting decisions reflecting the author’s detailed character descriptions from both The Distant Echo and A Darker Domain.
What Have the Cast Said About Their Roles?
While direct interview quotations remain limited in official press materials, verified background information reveals the performers’ professional trajectories. Lauren Lyle’s progression from supporting player in Outlander to series lead represents a significant career advancement, demonstrating ITV’s commitment to nurturing emerging talent within franchise properties.
Chris Jenks has established himself within the crime genre through simultaneous appearances in Vigil and Beyond Paradise, whilst Emer Kenny’s dual function as adapter and performer provides rare insight into the creative process. James Cosmo’s involvement lent gravitas to the second series, drawing upon his extensive experience in both British and international productions.
Key Takeaways About the Karen Pirie Cast
