In the shadows of a broken justice system, DCI Harry Cole is a man pushed to the brink.
When Keith Maxwell - pillar of the community, wealthy businessman, and school governor - is found brutally murdered, the public demands justice. But as Cole peels back the layers of Maxwell's 'respectable' life, he uncovers a stomach-churning reality: a predator with ties to the Albanian mafia, people trafficking ... and every parent's worst nightmare.
As DCI Cole follows the evidence, he realises that Maxwell's killer isn't a professional hitman. It's an innocent victim who finally fought back.
Convincing himself that Maxwell got exactly what he deserved, Cole orchestrates a high-stakes frame-up to protect the victim and pin the murder on a local crime boss. It's a win-win - one monster dead, another behind bars. But Cole is no stranger to the dark side; he has crossed the line into judge, jury, and executioner many times before.
Walking the razor's edge between hero and villain, Cole is just one step away from sharing a prison wing with those he has jailed. Can he ensure justice is done? Or has he gone too far?
