It's the eve of 1953, and Aloysius Archer is in Los Angeles to ring in the New Year with an old friend, aspiring actress Liberty Callahan, when their evening is interrupted by an acquaintance of Callahan's: Eleanor Lamb, a screenwriter in dire straits. After a series of increasingly chilling events--mysterious phone calls, the same blue car loitering outside her house, and a bloddy knife left in her sink--Eleanor fears that her life is in danger, and she wants to hire Archer to look into the matter. Archer suspects that Eleanor knows more than she's saying, but before he can officially take on her case, a dead body turns up inside of Eleanor's home...and Eleanor herself disappears. Missing client or not, Archer is dead set on finding both the murderer and Eleanor. With the help of Callahan and his partner Willie Dash, he launches an investigation that will take him from mobridden Las Vegas to the glamorous world of Hollywood to the darkest corners of Los Angeles--a city in which beautiful faces are attached to cutthroat schemers, where the cops can be more corrupt than the criminals...and where the powerful people responsible for his client's disappearance will kill without a moment's hesitation if they catch Archer on their trail.
