For more than 10 years, a mysterious and violent predator committed 50 sexual assaults in Northern California before moving south, where he perpetrated ten 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’. ‘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.
