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.

So, finding the answer should be straightforward, but it's as twisted as the DNA helix itself. 

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.

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.

Edinburgh, haunted by the ghosts of its many writers, is also the cold case beat of DCI Karen Pirie. So she shouldn't be surprised when an author's manuscript appears to be a blueprint for an actual crime.

What unspools is a twisted game of betrayal and revenge, but no one quite expects how many twists it will turn out to have.
