Karen Pirie turns a decades-old unsolved case into appointment viewing, built around a detective who refuses to let cold paperwork stay cold. The 2022 British drama pairs a true-crime podcast's renewed public interest with a police review that reopens old wounds in a small Scottish university town.
What is Karen Pirie about?
Set in St Andrews, the story follows Detective Sergeant Karen Pirie as she is assigned to revisit a quarter-century-old murder after a popular podcast starts picking apart the original investigation online. What begins as a routine paperwork exercise turns urgent once fresh leads surface and people connected to the original case start coming under threat. Karen has to work faster than the podcast's growing audience, chasing overlooked details the first investigation missed while keeping the people still living with that night's aftermath onside. The series leans into the friction between public true-crime obsession and the quieter, slower work of an actual police review, using the podcast framing device to keep raising the stakes on a case everyone had assumed was closed for good.
About the cast
Lauren Lyle leads as Karen Pirie, with Emer Kenny, Chris Jenks, Zach Wyatt, Rakhee Thakrar, Ariyon Bakare, Kevin Mains and Gemma McElhinney rounding out the ensemble across the show's Scottish backdrop. The cast carries a dual-timeline structure, moving between the present-day review and the circumstances of the original case, without the show ever losing track of who its central investigator is.
Context & significance
Karen Pirie arrived in 2022 as part of a wave of British procedurals built around a podcast-era premise: true crime as public spectacle colliding with the far less glamorous grind of reopening a closed file. The United Kingdom setting and the show's slow-burn structure give it a different rhythm than glossier crime dramas, with more time spent on interviews and institutional friction than on set-piece action. At around ninety minutes an episode, it has room to let the investigation breathe rather than rushing to a resolution.
