J. P. Beaumont and Brandon Walker, two of New York Times bestselling author J. A. Jance's most acclaimed series characters, join forces for the first time in one of the most suspenseful works of her career. Prospector Amos Warren and Big Bad John Lassiter, his young protege were as close as father and son until a violent argument tore them apart. The next day, Amos disappeared, never to be seen again. Years later, his bones were found in the desert. All signs pointed to John Lassiter, and Detective Brandon Walker made the arrest in the case. Now, more than four decades later, the retired Walker is called in when TLC--The Last Chance, a group of retired cops, criminalists, medical examiners, and district attorneys who devote their time and experience to solving stone-cold homicide cases--looks into the killing. Lassiter can get out of jail now for time served if he'll plead guilty to a lesser charge, but he refuses to cop to a crime he didn't commit. Lassiter's daughter, Amanda Wasser, wants Brandon and TLC to find Amos's "real" killer and clear her father's name. Brandon Walker's search to find the truth about Amos's killer eventually leads sixteen hundred miles north to Seattle, to an unsolved murder that could be connected to the case. Thanks to a mutual friend, Brandon gets in touch with crack investigator J. P. Beaumont. With the Special Homicide Investigation Team, affectionately known as S.H.I.T., disbanded and his wife away at a conference, the retired Beau has plenty of free time to help, even though he's skeptical about Lassiter's claims of innocence. J. P. Beaumont and Brandon Walker's connection proves all too crucial, for soon these seasoned detectives must pool their personal and professional expertise when someone close to Brandon falls into the hands of a cold blooded killer involved in a recent multiple homicide--who may also hold the key to the cold case.
