It must be recognized at the outset: this book provides a great reading pleasure. It is well written and it's important. The story is extraordinary in the literal sense. It is known and is particularly suited to the form of the book. The author can take the time to detail, tell and explore the details, uncertainties and questions that continually arise as and when it unfolds. There was that time the book, which is used to exit the journalistic form and simply sensational. There is no question here of the history of Jean-Claude Romand as a news item, but a story from a certain point of view: that of the author. It's not only the facts, there are the questions, doubts and interpretations of the author and therefore his views about the character. He puts filigree questions of how to give meaning to the acts and about a person who lies, for 18 years of his life, his wife, his parents and the people with whom he lives every day and it ends kill them, coldly. The end of the book I was particularly scared because the author comes to question possible sincerity in the religious approach, centered around prayer in prison in Romand. Would have changed? He has repented and is there again manipulating those around him? This man has lied, all the way to everyone and yet it manages to doubt the one that explored the depths of history. he wants this time, in the mystical impulse expresses Romand, it tells the truth. Personally I doubt it. Here we see how the Romand manipulator talent is exceptional. Jean-Claude Romand is a psychopath, he has the features: the lack of feelings of remorse, this manipulation and lies, and finally assumed this violence, which seems natural for him. For those who read English I would strongly advise to read just after "Without conscience: the disturbing world of the psychopaths among us" by Robert D. Hare, which gives the keys to the story. There is the story of Jean-Claude Romand and explanation of the psychologist that allows a dive into this fascinating but terrifying world of psychopaths.
