During the Northern Song Dynasty, in the city of Tokyo (now Kaifeng), the misty and rainy season was a good time when cicadas chirped and whispered and the breeze blew on the face. However, such tranquility was broken by a bizarre case.
That night, people in the capital were preparing for the upcoming Dragon Boat Festival. The streets and markets were busy and brightly lit. Bao Zheng, the governor of Kaifeng who is known for his unselfishness and loyalty, is silently thinking about a case in the palace that he has not yet completely clarified.
The cause of the case did not start with an obvious murder, but a bizarre disappearance that seemed to have no connection.
A young piano player named Chen Han lived in the southeast corner of Kaifeng City. He was quite famous at that time for his good piano playing. One day, Chen Han suddenly disappeared. People speculated that he might have left because he was in a bad mood, or that something unexpected had happened to him. However, what is strange is that his strings were left in the room where the crime occurred, and there are still unsolved notes hanging on the piano.
It was in such a mysterious case that Bao Zheng received help.
