This book showcases and uses a lot of what went through James Ellroy's mind as he grew up, through the murder of his mother, his street dwelling, panty robbing formative years, through to the crime / Americana writer he is today. Many of Ellroy's favourite themes are in here, the hyper intelligent outsider (also used as a cop in the Lloyd Hopkins stories) as well as Ellroys fascination with vampiric fangs (used again as the murderers MO in the Dudley Smith quarter). There are plenty of other favourites to be picked out for James Ellroy enthusiasts (what no one sided Russian Roulettes I hear you all cry) but to the unitiated it is still a good read and an excellent example of getting into a serial killers mind, a more viseral and tortured approach than Thomas Harris could ever attempt and Ellroy's killer has no real excuse other than parental lethargy to unhinge him, making the end product, a product of out times, a million times more scary than pantomime monsters whose sister was ate by wartime turncoats. (sorry if you are yet to read that particular "gem").
All in all a good read, it might dissapoint Ellroy fans who have only played with the Black Dahlia and LA COnfidential, but if you like the more crazy serial killer (a la Lloyd Hopkins) then you will enjoy this.
