Is a police officer or an essay on the psychological damage caused by childhood trauma? These three volumes explain in detail the consequences of malicious acts done on children. For me, these books go beyond simple police book. The horrors inflicted on children (incest, pedophilia, impact of wars) leave permanent traces. The brain drafts in various ways. 3 books difficult to read, which requires good concentration. It should read 3 volumes sets to not lose the thread. Personally I devoured the 3 volumes. The characters are well described. In short: To read while being aware of the horrors that will be described. This changes other detective novels.
