But when Rossi’s girlfriend is attacked—left in a coma in hospital—he becomes the killer’s new obsession and his own past hurtles back to haunt him. A killer out of control. As the body count rises, with one perfect murder on the heels of another, the case begins to spiral out of control. In a city wracked by corruption and paranoia, the question is: how much is Rossi willing to sacrifice to get to the truth?
