Kindaichi Shounen no Jikenbo

Synopsis

Yamato is found dead in the sealed Magamitori cave, strangled by the fake necklace which had been stolen along with the blade and mirror. Satsuki explains the Magamitori curse predicts the death of three people and tells how Kichieman's eldest daughter, eldest son and his wife all died. She says Magamitori gave three commandments; bury the artefacts, build four houses to worship him and the eldest daughter must become his servant. With news the phone is not working, three of the residents decide to leave, but are almost killed when the tunnel out of the valley collapses. Then, Asuka Minatoya's husband is killed by a huge falling copper bell. When they return, the fourth replica artefact, the bell, is missing. Later Soga is called out to meet one of the team, but is killed instead, however he is found near the broken seven angle mirror with pages from a torn day calendar in his hand. It is suggested that Satsuki and her mother may want revenge for Shiro Munakata's death a year earlier. Satsuki explains that her mother has been locked in the house since the age of 17 to serve Magamitori and she has never seen her face. Later, Kyouko Munakata approaches Hajime and Miyuki.
