Determined to find out exactly what happened to her former deputy chief, Jack Fielding, who was murdered six months ago, Kay is tricked into leaving Cambridge, Mass., and going to the Georgia Prison for Women near Savannah. Kay is there to see inmate Kathleen Lawler, who molested Jack as a child and later bore their daughter, Dawn Kincaid, a diabolically vicious killer.

When Ex-Manhattan ADA Jaime Berger asks for Kay's help exonerating a woman on death row for the murder of a doctor and his family, Kay finds herself uncovering inexplicable links to the murder of an Atlanta family, the deaths of homeless people in California, and more.
