The only suspects are the four young men now stained with her blood. Twenty-five years later the police mount a cold-case review of Rosie’s unsolved murder, and the four are still suspects.

Her investigation leads her back to past conflicts, false identities and buried secrets...

When a teenage joyrider crashes a stolen car and ends up in a coma, a routine DNA test could be the key to unlocking the mystery of a 20-year-old murder inquiry.

When a body is discovered in the remote depths of the Highlands, DCI Karen Pirie finds herself in the right place at the right time. Unearthed with someone's long-buried inheritance, the victim seems to belong to the distant past - until new evidence suggests otherwise, and Karen is called in to unravel a case where nothing is as it seems. It's not long before an overheard conversation draws Karen into the heart of a different case, however - a shocking crime she thought she'd already prevented. As she inches closer to the twisted truths at the centre of these murders, it becomes clear that she's dealing with a version of justice terrifyingly different to her own....

On a freezing winter morning, fishermen pull a body from the sea. It is quickly discovered that the dead man was the prime suspect in a decade-old investigation, when a prominent civil servant disappeared without trace. DCI Karen Pirie was the last detective to review the file and is drawn into a sinister world of betrayal and dark secrets. But Karen is already grappling with another case, one with even more questions and fewer answers. A skeleton has been discovered in an abandoned camper van and all clues point to a killer who never faced justice - a killer who is still out there.

It’s April 2020 and Edinburgh is in lockdown, but that doesn’t mean crime takes a holiday. It would seem like a strange time for a cold case to go hot—the streets all but empty, an hour’s outdoor exercise the maximum allowed—but when a source at the National Library contacts DCI Karen Pirie’s team about documents in the archive of a recently deceased crime novelist, it seems it’s game on again. What unspools is a twisted game of betrayal and revenge, but no one quite expects how many twists it will turn out to have.

Edinburgh, haunted by the ghosts of its many writers, is also the cold case beat of DCI Karen Pirie.

Karen can't ignore the plot's chilling similarities to the unsolved case of an Edinburgh University student who vanished from her own doorstep. The manuscript seems to be the key to unlocking what happened to Lara Hardie, but there's a problem: the author died before he finished it.
