In the second year of Tianxi, in Bianjing, a counterfeit jiaozi note marked on the back leads to a murder, a great fire, and a financial scam planned three months in advance. The judicial commissioner Zhongli Jinyue earns fifteen strings of cash a month and only wants to coast through life, but he is dragged into a conspiracy worth a thousand times his salary. Someone has forged the “official jiaozi seal” that the court has not yet approved, and is waiting to make a fortune. He does not have much time left.
