I highly recommend a novel called "Famous Detective: I Believe in Science". It's a light novel-a derivative fanboy detective genre. The protagonist of this novel was also a detective, but unlike Conan, he believed in science and could use scientific knowledge and skills to solve various problems. It was very interesting. In addition to this novel, I also recommend some classic mystery anime: "The Detective,""The Chronicles of Kaneda,""The Double Detective," and so on. I hope you like this fairy's recommendation.
