The story is about solving a 20-year old murder, a Cold Case, using DNA evidence. Cliff and his associate Maeva are hired by the grand-daughter of the victim to solve the case. The story brings us to various places in Northern California and Nevada.
It must have been inspired by the Golden State Killer case that was solved by DNA some years ago. The case is mentioned in the book. In the first part of the book I had trouble following and remembering all characters and names, but when you're searching for someone through DNA it's an inherent part of the story. Once the focus was on a small number of potential murders it became a page turner. I enjoyed the reading!
