Advertisements Haven't watched it yet, wanted to get a thread started... I'll Be Gone In The Dark is a documentary on HBO, based on the book of the same name, by Michelle McNamara. The book is a true-crime story of the hunt for the Golden State Killer. The book was released posthumously on February 27, 2018, nearly two years after McNamara's death and two months before an arrest would be made in the case. The book's title is a reference to a direct quote spoken by the Golden State Killer to one of his victims: "You'll be silent forever, and I'll be gone in the dark." As I understand it, the HBO mini-series (6 eps) is sort of a meta-mash of both the GSK's crime spree, and McNamara's obsessive hunt for him.
