I listened to the ebook on a road trip and air trip and found the story fascinating and terrifying. Being in the Bay Area it was unreal to imagine the terror the GSK in his many alleged personas inflicted on Sacramento and later other parts of the Bay Area and California. This terror, woven in with the great investigative efforts of the author, her story, and the past and future of criminal investigations was a real treat. I thought the book was too exhaustive in parts, but that's where tuning out an ebook is easy. That said, I'm still happy I listened and keen to find out the outcome of the GSK's trial in real time.
