In the #1 New York Times bestselling thriller that inspired the TV series King & Maxwell, two private investigators dig into a killer's past--but when their search threatens powerful enemies, it could cost them their lives. Edgar Roy--an alleged serial killer--is awaiting trial. He faces almost certain conviction. Sean King and Michelle Maxwell are called in by Roy's attorney, Sean's old friend and mentor Ted Bergin, to help work the case. But their investigation is derailed when Sean and Michelle find Bergin murdered. It is now up to them to ask the questions no one seems to want answered: Is Roy a killer? Who murdered Bergin? The more they dig into Roy's past, the more they encounter obstacles, half-truths, dead-ends, false friends, and escalating threats from every direction. Their persistence puts them on a collision course with the highest levels of the government and the darkest corners of power. In a terrifying confrontation that will push Sean and Michelle to their limits, the duo may be permanently parted.
