If you just heard about this book recently and think it’s about how the so-called Golden State Killer (GSK) was finally identified, think again. It’s the story of his crimes, and of one now-deceased woman (the author, who was an amateur/civilian), who became obsessed with him. She writes well and describes his crimes in detail as well as depicting the detectives and many others whose lives intersected with him. However, the book was published in February 2018, two months before the GSK was identified and arrested. He is now awaiting trial. It is very frustrating to get to the end and find that you cannot find out which of the myriad theories was correct. Which profilers got it right? Which parts of the profiles were right? Was the name of the GSK ever in the database of suspects? How was he caught? These questions are not answered in this book.
