Thirteen years ago, a wrongful conviction sent an innocent man to prison. Still mentally and physically scarred six years after his release, William Law believed the darkest days of his life were behind him, until the night he is attacked in a dark alleyway. As Law tries to deal with the outcome and struggles to understand the reasons behind the encounter, a more troubling presence begins to make itself known. Meanwhile, a missing teenager's disappearance is being treated as a murder investigation. Homicide inspector Mac Jackson is leading the inquiries. With no contact, no ransom demand, and all the leads exhausted, his case soon grows cold. Then Jackson receives an anonymous phone call from a tipster with some startling information. As Jackson follows up on the new lead, he unearths clues connecting one crime to another, and learns that the most unconventional path might be the only one that leads to the truth.
