In the fog of old Shanghai, two shadows walk together.
In the Republic of China, there was a turbulent undercurrent on the beach in Shanghai, and a series of bizarre and murderous cases emerged one after another: the mystery of arson in red costumes, the murder of golden cicadas escaping from their shells at the fire scene, the murder of the Tarot of the God of Death in reverse in the secret room... Chen Xing, a mercurial and clever man, and Shen Zhansheng, a calm and restrained man, accompanied by detectives, walked side by side through the streets of old Shanghai, unraveling conspiracies and exploring people's hearts.
The old case of the Shen family's extermination that Shen Zhansheng had buried for five years was full of doubts, and the forces behind the scenes were trying to block it step by step. The two of them were involved in a series of crimes, solving the mystery in the city, and digging into the old blood feud. The murderous case hides the joys and sorrows at the bottom, and the conspiracy involves the interests of all parties. Two partners with complementary personalities pursue the truth in the fog, and support each other in dangerous situations. A series of unsolved cases are connected in a volume, revealing the sin and sadness hidden deep in the city under the skin of the prosperity of the old era.
