1971’s The Village of Eight Graves is the third novel in Seishi Yokomizo’s Kosuke Kindaichi mystery series. The 2021 English translation is by Bryan Karetnyk.
Tatsuya survived unspecified unpleasantness during the conflict of the early to mid-20th century and returned to Japan to discover that he no longer had a family or home. His mother is long since dead, his step-father has died during the war, and his step-family has scattered to parts unknown. Having no other choice, he has built an unremarkable solitary life for himself in the Japan of the 1940s.
Thanks to his late mother’s unwillingness to speak of her past, Tatsuya has no idea that he was born into a family, and a rural village, scarred by terrible events. Ignorance is no defense. History seeks him out.
The aging matriarchs of the Tajima family summon Tatsuya to their home village. They believe that he is their long-lost nephew. As such, he is the Tajimi family’s only healthy, adult male heir. Such good fortune! Save for the fact that the community to which he is summoned is the ominously named Eight Graves.
