It's a cold November night, and DS Dennis Milne is waiting to kill three unarmed men.
Cynical and jaded, Milne earns money on the side by doing what he does best: punishing the bad guys.
But he's been set up.
This time, instead of shooting drug dealers, he kills two customs officers and an accountant.
The hunter has become the hunted. With his colleagues and his enemies closing in on him, Milne must use all of his skills, just to stay alive.
