L.A. psychologist-detective Alex Delaware has received a strange, anonymous package in the mail. Inside is an album filled with gruesome crime-scene photos. When his old friend and colleague, homicide detective Milo Sturgis, views the compendium of death, he is immediately shaken by one of the images: a young woman tortured, strangled, and dumped near a freeway ramp. The murder was one of Milo's first cases as a rookie homicide cop: a vicious killing that he failed to solve--and has haunted him ever since. Now, two decades later, someone has chosen to stir up the past. As Alex and Milo set out to uncover what really happened twenty years ago, their relentless investigation reaches deep into L.A.'s nerve centers of power and wealth--past and present. While peeling back layer after layer of ugly secrets, they discover that the murder of one forgotten girl has chilling ramifications that extend far beyond the tragic loss of a single life.
