This book is one of the best (the best?) With serial killer thrillers. Not only the author brilliantly describes the meanders of the psychology of the killer, his past, his impulses, but also analyzes the "impact" of such a killer on society: everybody goes, journalists, politicians, police officers, who are all interested in this manhunt. It is a dark and violent book, with a relentless mechanical, passionate, disturbs and delights. It is hilarious: a must read for fans of the genre.
