Evidence is unnecessary for a professional and unprofessional detective. A detective is not a policeman, not a judge, not a lawyer. I can know some strange non-human beings, such as top criminals, who are also murderous, so naturally there may also be beautiful, gentle and lovely, understanding, well-educated, and life-and-death beautiful agents. (The background of this book is Europe, Does not involve any discriminatory topics. In addition, there may be differences in small details between the Shrimp-Europe plate and the Europe-continent plate that everyone normally recognizes. Refuse to take a seat.)
