Karen Pirie

St Andrews, 1996. Three drunken students stumble upon the body of a young woman named Rosie, who was assaulted and left for dead in the cathedral grounds. The only suspects are the three students, stained with her blood. Twenty-five years later, Rosie's murder has become the subject of a provocative true-crime podcast, and DS Karen Pirie is unexpectedly put in charge of the cold-case review.

With the suspects under attack, Karen's case becomes a live investigation overnight. But is Ziggy's death a revenge killing, or is Rosie's killer trying to bury the truth? In 1996, the recovery of an abandoned car leads to an arrest, but with a lack of evidence, the investigation flounders-until a potential eyewitness brings DI Maclennan new hope. In the present, Karen makes a shocking discovery.

Damning forensic evidence leads to a shock arrest. Karen brings the suspect in for questioning, but she has only 24 hours to build a case. Bel's callout on the podcast produces an eyewitness, whose testimony leads Karen and Murray to a horrifying possibility. With a new lead to pursue, Karen is forced to confront a version of the truth she had never thought possible.
