James Ellroy gives us a chilling demonstration of the dynamic realism of the serial killer, and for good reason, since the narrator is none other than the killer himself. Some scenes are impressive of violence, both physical and psychological, which is reminiscent of the famous "American Psycho" BE Ellis in less sanguinolant however (which is a good thing) but with a beautiful portrait most end of the main character, as the narrator gives us the story of his childhood, his trauma, his first deviances, and we follow its evolution (especially sexual). This immersion in the mind of the killer, the psychological tension and perfectly controlled suspense make this book a great success. The story is cleverly interspersed with newspaper articles, which gives the reader a more distanced view of events. Finally the originality and strength of this thriller is the encounter and the relationship that will forge between the narrator and another serial killer. Warranty intensity.
