This book goes into the life and thought process of Mark David Chapman, who murdered John Lennon just hours after getting his autograph. He just shot him four times on the street and hung out until the police arrived to arrest him. He was absolutely obsessed with The Catcher In The Rye, which he claimed was his manifesto and that he saw himself as the main character of the book. I have watched some interviews with Chapman, and he seems like he has some serious mental problems of some variant just from those tapes. Learning about him in this book confirmed that theory of mine. There is an episode on Mark David Chapman on The Last Podcast On The Left, and this book was featured on the reading list. The book was written nicely, but reading some of the drivel that Chapman came up with eventually got irritating to me.
