1932, Shanghai Beach. This is a bizarre city, where the prosperity of the old world is intertwined with the restlessness of the new world. The water of the Huangpu River reflects countless darkness and sin. This city tolerates everything, but it also swallows everything.
In the heart of Shanghai Beach, there is the famous Nanjing Road. There are flashing neon lights on both sides of the road, and a constant stream of pedestrians and rickshaws pass through this bustling commercial district. But behind this prosperity, there are many unspeakable secrets hidden.
In a corner of this city, a murder that shocked Shanghai attracted the attention of the police. The deceased was a foreign businessman named Richard Hopkins, a British national, about 30 years old, tall, and often wore a crisp suit. His body was found in the penthouse suite of a high-end hotel, the Blue Sky Hotel. The door was locked from the inside and the windows were closed. There was no abnormal damage to the doors and windows. The cause of death was initially determined to be poisoning.
