When the story begins, Song Ci is standing on the bluestone pavement in Bianjing, frowning slightly and feeling a little heavy in his heart. The early autumn sunshine shines through the treetops and onto the ground. There is a trace of moisture in the air, as if it indicates that something unusual is about to happen. Song Ci has always been known for his sharp vision and calm reasoning ability, and he can solve almost all cases easily, but he knows that some things cannot always be judged based on their appearance.
This morning, just after returning from the Yamen, Song Ci received an urgent letter. The letter paper has turned slightly yellow, and there is still wet cinnabar on the seal in the corner. This letter comes from a wealthy family in Bianjing, and the letter reveals clues to a bizarre disappearance case. The missing person is not an ordinary person, but the eldest son of the family - Chen Siyuan, a young man in his twenties. There was no news from him overnight, as if he had disappeared out of thin air. What's even more strange is that there was a trail of blood on the ground outside Chen's house, but no body was found.
Song Ci knew very well that this was not a simple disappearance case, but most likely a well-planned murder. The appearance of bloodstains, if there is no body, there must be a complicated secret hidden behind it. And those who disappeared may not have disappeared completely, but instead buried a deeper mystery in a dark corner.
