Read this book is only if you like the tnovels that are tightly logical, then be sure to read Agatha Christie's "And Then There Were None". The reason why I recommend this book is that it describes the dark side of the whole society. Three professions shrouded in the glory of the altar, but another describes them. They no longer keep the otath, and begin to accept benefits. What they reflect is the hypocrisy and the ugliness of the whole society. Moreover, all the readers separate themeselves from the whole situation and quietly enjoy as the spectators. The killing of four people who are also guilty. The author perfectly portrays different human nature.
