I’ll Be Gone in the Dark by Michelle McNamara

I’ll Be Gone in the Dark: One Woman’s Obsessive Search for the Golden State Killer chronicles McNamara’s relentless investigation into a serial rapist and murderer who terrorized California in the 1970s and 1980s (“East Area Rapist,” later known as the “Golden State Killer”). Her decade-long pursuit included poring over police files, interviewing survivors, and engaging online communities dedicated to cold cases.
