The File of Young Kindaichi (1997 ) Episode 36

Hajime calls everyone together believing he has solved the murders. He explains that the killer used a large piece of jade in Yumi's room as a counterweight to help him descend from the room through the window. This indicates the killer is lighter than Yumi, implicating Yoichi Takato. Hajime also explains that Takato sent Yamagami's body to the hotel as baggage addressed to himself as Mario Totsune. Confronted with the evidence, Totsune confesses to the elaborate scheme and reveals that he is the only son of Reiko Chikamiya. He was raised by his father and only saw Chikamiya twice, but was fascinated by magic, and only found out she was his mother after his father’s death and saw her Magic Notebook. After seeing the Living Puppet act and their other tricks, he realized the team also had a copy of Chikamiya's notes and later when he became the manager, he overheard them reveal their involvement in her death. Sakonji confirms the story and gives Takato his copy of the notebook. Takato is taken away by the police, however, he knows a trap is already set. A few weeks later, when Sakonji performs a new death-defying act, he is killed because Chikamiya wrote an intentional flaw into her notebook. With Sakonji's death, Takato escapes from prison with Hajime vowing to catch him in his grandfather’s name.
