I recommend the following two mystery novels to you: 1. "Detective Dixson": Benji's detective and mystery novel. Every case has a secret that no one knows about. People follow the footsteps of Detective Dixson to explore the secrets behind them. He believed that every time he looked at it, he would have a different discovery and surprise. 2. "Detective Tale": Keigo Higashino's mystery novel. Each volume has a different case to unfold. Behind each character is hidden a secret that no one knows. It makes people think and reason, and it makes people unable to put it down. I hope you like my recommendation. Muah ~
