"Under the Platycodon"
Lin Mo and Shen Yanzhi of the Municipal Criminal Investigation Team are the most tacit partners in the police force - she is a forensic doctor who can read the truth from the corpses, and he is a criminal policeman who is good at tracking clues. The two were brought up by Zhou Yan, the old captain who was both their teacher and their father. Zhou Yan is the most trusted "Uncle Zhou" in their hearts and is also recognized as the Dinghai Shenzhen in the police force.
However, a case of corpse dismemberment on a rainy night broke the peace. The military canvas on the deceased's body, the linen embroidered with platycodon flowers, and even the sleeping pills found in the autopsy all pointed to Zhou Yan. As cases occurred one after another - the director of the hospital pharmacy was poisoned by drugs, and the retired teacher died of blunt force blows, clues pointing to "Uncle Zhou" were left at each scene, and there were also hidden code words pointing to a mysterious "Mr."
Lin Mo and Shen Yanzhi were forced to struggle between trust and suspicion. They discovered that these cases not only connected current crimes, but also involved old cases in which Lin Mo's parents and Shen Yanzhi's father died many years ago. And the "sir" that all the clues ultimately point to seems to be hiding beside them. When the last piece of the puzzle was put together, they were shocked to realize that the person they had relied on and regarded as family since childhood might be the abyss itself.
