I’ll Be Gone in the Dark

Soon to be an HBO Documentary Series

Introduction by Gillian Flynn

Afterword by Patton Oswalt 

A masterful true crime account of the Golden State Killer – the elusive serial rapist turned murderer who terrorized California for over a decade – from Michelle McNamara, the gifted journalist who died tragically while investigating the case. 

“You’ll be silent forever, and I’ll be gone in the dark.”

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. 

At the time of the crimes, the Golden State Killer was between the ages of 18 and 30, Caucasian, and athletic – capable of vaulting tall fences. He always wore a mask. After choosing a victim – he favored suburban couples – he often entered their home when no one was there, studying family pictures, mastering the layout. He attacked while they slept, using a flashlight to awaken and blind them. Though they could not recognize him, his victims recalled his voice: a guttural whisper through clenched teeth, abrupt and threatening. 

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. Framed by an introduction by Gillian Flynn and an afterword by Michelle’s husband, Patton Oswalt, the book was completed by Michelle’s lead researcher and a close colleague. Utterly original and compelling, it is destined to become a true crime classic – and may at last unmask the Golden State Killer.
