I'll Be Gone in the Dark: One Woman's Obsessive Search for the Golden State Killer – A #1 NYT Bestselling Serial Killer Investigation

I'll Be Gone in the Dark tells the true story of a serial rapist and murderer who committed fifty sexual assaults in Northern California during the 1970s and 1980s before moving south, where he perpetrated ten murders. For three decades, he evaded capture by multiple police forces and detectives. Michelle McNamara, a true crime journalist and citizen detective who created the website TrueCrimeDiary.com, spent over ten years investigating the case. She pored over police reports, interviewed victims, and engaged with online communities focused on the unsolved crimes. McNamara called the killer "the Golden State Killer" and was determined to identify him. This book, which McNamara was writing at the time of her sudden death, combines investigative journalism with memoir. It examines the criminal's crimes and their impact, while also documenting McNamara's personal obsession with solving the case. The case was solved in April 2018. The book includes an introduction by Gillian Flynn and an afterword by Patton Oswalt.
