Kindaichi Shounen no Jikenbo EP13 - Isle of Sadness Murder Case File 1

Hajime and Miyuki participate in a treasure hunt on the Isle of Sadness (Hiho) in Kyushu organised by Daisuke Mimasaka. The others who are also participating are treasure hunters Asato Kakimoto, Ryuzo Yasojima, Kohei Himura, Hisayoshi Yaogi, Chris Einstein, the former butler Eisaku Iwata, Kyoko Kaya and Mimasaka's daughter Midori Mimasaka. Upon arrival at the island, they discover the decomposed body of Mimasaka, stuffed into a grandfather clock. The only clues are a Yamawara statue, a set of eight dolls, an old song whose lyrics are supposed to provide clues to the location of the treasure. In Tottori folklore, the Yamawara defends the treasure on the island and kills those who get close, hence the name of the island. The treasure hunters insist on continuing with the hunt and they discover that there is one extra guest who must be the killer. The next morning, Hajime notices a doll missing, and Asato Kakimoto is found dead in his lodge with blood splattered all over the floor, walls and ceiling, but everyone has an alibi.
