Doctor Qin: ExecuterEP 16

A woman is found dead in a cage on the outskirts of Longfan City, her body mauled by feral cats and bearing a fatal stab wound to her chest. Dr. Qin Ming finds traces of a hallucinogen, fluorescent powder, and mysterious letters from the "Executer." The clues soon lead to a web of linked murders involving a missing daughter, an abusive vice president, and a long-lost love who vanished a decade ago, all pointing to a secret room in a villa and a revenge scheme that has been quietly unfolding for ten years. But when every clue falls into place, the truth is more suffocating than the evil behind it.
