第 27 集: 金田一殺人事件檔案 4

Hajime believes that he has identified the killer, and lies in wait with his friends and the police in Tachibana's room. Later, a masked man walks in to recover the hidden manuscript and is captured. Hajime explains that the key to the code was the names of the invitees to the party which suggested that the data disc containing the manuscript was hidden in the grandfather clock and they find it there. Hajime also explains how the killer was able to exit Tachibana's room without leaving footprints in the mud outside. He then reveals Tetsuo Tsuzuki as the killer of five people; Goryu Tachibana, Kon Omura, Wataru Tokito, Ohei Katsura and Nonaka Tomomi. Tsuzuki confesses, saying that he did it for his 10-year-old daughter Mizuho who has kidney failure. He donated one of his kidneys to save her, but the hospital bungled the operation and the transplant was a failure. In desperation to save his daughter, he smuggled organs for a crime boss, but Tachibana found out and was going to expose him. Suddenly, Tsuzuki commits suicide by stabbing himself in the stomach and makes a last wish for his remaining kidney to be given to his daughter. (Source: Wikipedia)
