On an innocent evening stroll with her child, Melanie stumbles across a horrifying crime scene. A wealthy former prosecutor from her office has been tortured and murdered, his luxurious town house set ablaze to destroy evidence of the crime. It's the kind of high-profile case that can make her name, and Melanie wants in. Needs in. But what she doesn't realize is that this opportunity will bring her dangerously close to a hard-to-resist FBI agent who may have secrets of his own--and even closer to a dark, sadistic killer who seems to be one step ahead of her every inch of the way.
