SYNOPSIS

In the heart of Edinburgh, a grim discovery plunges DCI 'Mac' McNeill into a seedy world of organised crime, where a sinister plot reaches beyond mere territorial disputes.

As Mac navigates the treacherous crossfire of rival crime lords and delves into the lives lost to the city's drug trade, a killer strikes from the dark underworld.

As he unravels a vendetta steeped in revenge and loss, the line between hunter and hunted blurs, testing his resolve and forcing him to confront the ghosts of his own past.

With time running out and the stakes higher than ever, Mac must outmanoeuvre a ghost hell-bent on delivering a final, devastating message. But as the investigation takes him from the streets of Edinburgh to the remote highlands, he finds himself out of his element and racing against the clock.

A riveting tale of vengeance and retribution; DCI McNeill’s greatest challenge yet.
