On January 15, 1947, the tortured body of a beautiful young woman was found in a vacant lot in Hollywood. Elizabeth Short, the Black Dahlia, a young Hollywood hopeful, had been brutally murdered. Her murder sparked one of the greatest manhunts in California history.

Martin Michael Plunkett is a product of his times—as a child, he possessed a genius intellect, but also a pitiless soul and heart of blackest evil burnished in his adolescence. By the 1960s, Plunkett finds himself in the bay city of San Francisco, amid Charles Manson hysteria, where he indulges in savage and terrible impulses. He is revealed to himself as a pure and perfect murderer. Thus begins a decade of discovery and terror, the coming-of-age of a criminal, pieced together through police reports, media coverage, and confessions.

Three citizens are butchered during a liquor store holdup. An unstable veteran cop vanishes without a trace. Nothing connects these events except for a nagging hunch in the back of Detective Sergeant Lloyd Hopkins' brain--a sinister foreboding that will lead him through the sin-and-sleaze playground of nighttime L.A. on the trail of a psycho psychiatrist with a talent for terror and mind-control. His gore-soaked journey through Hell will plunge this determined manhunter into the dark heart of madness--and beyond.

In 1958 Jean Ellroy was murdered, her body dumped on a roadway in a seedy L.A. suburb. Her killer was never found, and the police dismissed her as a casualty of a cheap Saturday night. James Ellroy was ten when his mother died, and he spent the next thirty-six years running from her ghost and attempting to exorcize it through crime fiction. In 1994, Ellroy quit running. He went back to L.A., to find out the truth about his mother--and himself.

January '42. L.A. reels behind the shock of Pearl Harbor. Local Japanese residents are rounded up and slammed behind bars. Massive thunderstorms hit the city. A body is unearthed in Griffith Park. The cops tag it a routine dead-man job. They're wrong. It's an early-warning signal of chaos. There's a murderous fire and a gold heist. There's Fifth Column treason on American soil. There are homegrown Nazis, Commies, and race racketeers. It's populism ascendant. There's two dead cops in a dive off the jazz-club strip. And three men and one woman have a hot date with history.
