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.

Introduction by Gillian Flynn • Afterword by Patton Oswalt

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

For more than ten years, a mysterious and violent predator committed fifty 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 and citizen detective 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 powerful memoir, a portrait of a woman’s obsession and her unflagging pursuit of the truth. Utterly original and compelling, it has been hailed as a modern true crime classic—one which fulfilled Michelle's dream: helping unmask the Golden State Killer.

  • A Groundbreaking True Crime Memoir: Follow the author’s obsessive search for the truth, a quest that tragically cost her her life but ultimately led to justice.
  • Meticulous Investigative Journalism: Delve into the complex case files, witness interviews, and online communities that Michelle McNamara navigated to piece together the killer’s identity.
  • The Hunt for a Serial Killer: A chilling account of the violent predator McNamara dubbed “the Golden State Killer,” who terrorized California with fifty assaults and ten murders.
  • Solving a Decades-Old Cold Case: Discover the story that captured a nation, a modern classic that helped unmask one of America’s most elusive criminals years after the trail went cold.

The last book from M. McNamara parts of the book were finished by others with knowledge of her research and writing style. To me, this felt like it was a recap of the crimes and less of a piecing together of evidence leading to the perp.

It was too bad Michelle McNamara didn’t get to finish this book. The parts written by her were very well written and really drew me into the narrative. I believe if she had been able to finish it herself it would have been tighter overall.

I'm a little obsessed with true crime stories, and Michelle McNamara was living my dream - an amateur sleuth who was able to investigate a cold case full time. While married to the funniest guy on earth! Sadly, her obsession with this case probably did lead to her early death. Also sad that she did not live to see the killer finally caught after four decades. It's interesting, now knowing who the real killer is, to read her thoughts on it, and those of the professional investigators working the case, and the descriptions from victims, to see how they matched (or didn't) the real culprit. She was a great writer and researcher. She dug deep for not just cold, sterile facts but also the humanity, the stories of the victims themselves.

Breathtaking story and painfully sad that it is true. Amazing how Michelle doggedly investigated and horribly sad that she didn’t get to see him caught.
