The haunting true story of the elusive serial rapist turned murderer who terrorized California during the '70s and '80s, and of the gifted journalist who died tragically while investigating the case - which was solved in April 2018.

“A brilliant genre-buster.... Propulsive, can’t-stop-now reading.” (Stephen King)

For more than 10 years, a mysterious and violent predator committed 50 sexual assaults in Northern California before moving south, where he perpetrated 10 sadistic murders. Then he disappeared, eluding capture by multiple police forces and some of the best detectives in the area.

Three decades later, Michelle McNamara, a true-crime journalist who created the popular website TrueCrimeDiary.com, was determined to find the violent psychopath she called "the Golden State Killer". Michelle pored over police reports, interviewed victims, and embedded herself in the online communities that were as obsessed with the case as she was.

I’ll Be Gone in the Dark - the masterpiece McNamara was writing at the time of her sudden death - offers an atmospheric snapshot of a moment in American history and a chilling account of a criminal mastermind and the wreckage he left behind. It is also a portrait of a woman’s obsession and her unflagging pursuit of the truth. Utterly original and compelling, it is destined to become a true-crime classic - and may at last unmask the Golden State Killer.
