In the years leading up to her death, true crime writer Michelle McNamara diligently researched the serial killer and rapist that she labeled “The Golden State Killer.” Only two months after the posthumous publication of this book, a suspect was finally identified and arrested in connection with the decades-old crimes. I’ll Be Gone in the Dark reads partly as a police procedural mystery, with focus on the investigators, the collection of evidence, the piecing together of threads over the years, and the different theories swirling around the unsolved (at the time) case. It also reads as a bit of an autobiography of McNamara, with both the stories of her own life and her emotional connections to cold cases that she intended to share and the annotations about her writing process added by those close to her after her death. The interwoven plot lines of the investigators and writer in their relentless pursuit of justice made the book a gripping and powerful read at the time of its publication.
The arrest of Joseph DeAngelo only heightens the book’s appeal. Readers who may have been astounded that a cold case could be broken after so many years can see the inner workings of the investigation–the sometimes wild leads investigators followed relentlessly, some dead ends, but others astoundingly prescient given the investigation’s conclusion. The knowledge that the killer was finally caught also adds some catharsis to an otherwise unsettling ending where the killer remained free and the writer did not live to pursue her investigation further.
True crime is a tricky genre, especially for relatively recent crimes where in-depth studies may seem voyeuristic or insensitive to those loved ones still grieving. Through her focus on the investigation, McNamara gives a clear sense of purpose to every detail that she includes. The more graphic and salacious information is not provided to shock readers or to dramatize a family’s tragedy, but rather to build a wall of evidence with which to ultimately bring the killer to justice. If you are interested in this case or in true crime, I would highly recommend this book.
