The Fourth Skeleton

Ming Wei, chief forensic pathologist at the Linjiang City Forensic Center, uses her keen professional instincts to uncover something unusual in what appears to be an ordinary case of a woman drowning: fibers found beneath the victim's fingernails perfectly match evidence from an unsolved case three years earlier. As the investigation deepens, more bodies appear one after another: a second corpse carefully laid out at the center of an abandoned theater stage, and a medical student with a scalpel blade left beside her... Every strange clue points to Ming Wei's father, the renowned surgeon Ming Zhenguo.

Criminal Investigation Squad Captain Lei Rui and newly transferred detective Qiao Zifeng join the investigation, each with his own agenda. Lei Rui has a confidential file concerning a medical accident from twenty years ago, while Qiao Zifeng's younger sister was the victim in the unsolved case from three years earlier. When Ming Wei discovers that a figure has been deliberately cut out of an old photograph in her father's study, she realizes that the killer not only knows her father's past, but is also using the bodies to piece together a revenge plot spanning twenty years.
