Snow Country Murder Case is a murder mystery that pays homage to the classic Snow Country, by the awards-wining novelist Yasunari Kawabata.
Therefore, this murder mystery shares a lot of similarities with Snow Country in character settings (a traveling man, a geisha and her 'younger sister'), locations and plots (e.g. the love triangle among the MC, the geisha and her 'sister'). The murder mystery itself is quite simple (still it isn't easy to guess who is the real murderer), but the relationships among the characters and their different backstories are a bit more complicated.
In the end, the mystery and the murderer's motive is logically explained and the love triangle meets , it is an easy and interesting read, but it isn't very outstanding.
