Team A discovers a body of a young woman (Shum Po-yee) inside a kitchen stove that is enclosed with cement. They suspect that her husband (Chan Tik-hak), who is the first to discover her body, is the killer. They bring him in for questioning, but he is quickly released due to the lack of evidence. A few nights later, the team discovers the husband hanged at his apartment and concludes that his suicide was actually a murder. After further investigation, they find that Shum's "cousin" was actually a past boyfriend who killed the couple in a fit of rage. Based on the "Kitchen stove murder case" (灶底藏屍案) in 1975. |||||
