Castle Peak Shadow

Su Huaqiang, the son of wealthy businessman Su Lin, claimed that his father's "fall from Huashan Mountain" was actually the murder of his stepmother Chen Meilin, and not an accident as previously determined. Lin Qiu, captain of the Criminal Police Brigade of the Qingshan City Public Security Bureau, conducted an in-depth investigation and found that the case was full of doubts. As the investigation progressed, Lin Qiu's team dug up Chen Meilin's astonishing past: in the past nine years, all four of her husbands suffered misfortune, and each incident was disguised as an accident or suicide. In the He Zhitao case and the Su Lin case, a mysterious "lone man" appeared. In the Hainan case, the man's alias was "Yang Chen", but his identity information was all forged, and the clues were interrupted for a time. At the same time, Lin Qiu discovered that Chen Meilin was actually one of the twins. Her real name was Chen Xiang, and her younger sister was named Chen Lan (later renamed Wang Shuang). The two were adopted separately when they were 7 years old. The breakthrough point in the case came when fitness coach Zhang Qian was found dead. Further digging revealed that Zhang Qian was the mysterious "lone man" in the two cases. She pretended to be a man and committed crimes for him, and was paid 200,000 yuan each time. After Chen Meilin became aware of the suspicion of the police, she began to implement the "Golden Cicada Escape": she first removed the iconic black mole on her left elbow and learned tattooing techniques; then she pretended to evade the police interview, escaped from surveillance in a bathing center, and then killed Zhang Qian to silence her; finally, she lured her sister Wang Shuang to a B&B, got her drunk and killed her, and then tattooed a fake mole on Wang Shuang's left elbow to fake her own death, while she took Wang Shuang's identity and lived a low-key life. Relying on his keen observation, Lin Qiu saw through the identity substitution conspiracy from the subtle scars on the arm of Wang Shuang (actually Chen Meilin) ​​in the video, combined with the fake mole on "Chen Meilin's body". The police quickly captured Chen Meilin.
