This book is fascinating. Incredibly well-written true crime by the true Master of the genre. I’ve read 4/5 of his books and each is a masterpiece. This one is engrossing and addictive. Though I don’t have any sympathy for the killer, and don’t care what his genetic code meant for personality. That’s just blaming anything do as to not blame the killer. Kevin Pierce is such an amazing narrator. I’m so glad he narrates all Olsen’s books.
