Murder at Mt. Fuji

Murder at Mt. Fuji (Wの悲劇, Daburyū no Higeki^?, The Tragedy of W) is a Japanese novel by author Shizuko Natsuki, originally published in 1982. It has been adapted into several Japanese television dramas and a film.

"I've stabbed Grandpa to death." With these words, rich heiress Chiyo Wada incriminated herself in the murder of her grandfather, Yohei Wada, the patriarch of a rich family owning a large conglomerate. Chiyo had brought along her friend Jane Prescott to spend the New Year holidays with her family: Yohei, grandmother Mine, grand-uncle Shigeru, mother Yoshie, stepfather Sawahiko, cousin Takuo, and Dr. Shohei Mazaki, who's rumored to be an illegitimate member of the family.

When Yohei is killed, the investigation is undertaken by detectives Ukyo Nakazato and Katsubei Aiura, who have more questions than answers. Did Chiyo really murder her own grandfather, a known playboy who often groped her? Or was she set up by another family member? The answers will be decisive for the Wada family to stay together - or break apart…

In all audiovisual media adaptations the character of Jane Prescott, an American, is replaced with a Japanese character named Haruo Ichijō (一条 春生, Ichijō Haruo^?), with varied degrees of relationship with the rich heiress Mako Watsuji (和辻 摩子, Watsuji Mako^?).
