The Detective Novelist and the Thief was a Japanese story about a novelist who was caught in a crisis because of a mystery novel involving conspiracy and theft. He finally solved the crisis by cooperating with a thief. This book made me very interested in Keigo Higashino's mystery novels. The plot of the story was so compact and fascinating that it was hard to predict. Each character in the novel has their own unique personality and motivation, allowing the reader to understand their actions and decisions more deeply. The novelist in the story was also a very interesting character. He was not only a mystery novelist but also a person who loved life and enjoyed life. In the process of writing novels, he was constantly faced with various challenges and difficulties, but in the end, he succeeded in overcoming these difficulties and created a novel full of imagination and creativity. The book also explored some questions about human nature and morality. In the story, the novelist and the thief had a relationship of mutual help and support. This relationship not only allowed them to solve a problem together, but also made them understand and respect each other more. I think this book is well worth reading. Not only because it is an interesting mystery novel, but also because it reveals some human nature and moral issues and inspires us to think about the truth of life and happiness.
