After twenty years on the force, Detective Chief Inspector Jack Logan thinks he has seen it all.
He is wrong.
When a nurse is murdered on her way home from nightshift, Jack and his team go on the hunt for her killer.
As more victims are uncovered, Jack finds himself tracking a murderer afflicted by a unique psychosis - one that leaves him free to maim and kill without a shred of remorse.
Facing a new type of killer in an unfamiliar city, DCI Jack Logan is about to be pushed to his limits, before being forced to realise just how little he truly knows.
