This was intriguing up until I guessed who the killer was. Once Colly figured it out it was annoying that she said stuff like “The killer will be” instead of just saying the person's name because why wouldn't you? The last two chapters were painful as she recounted in detail the crime. Other than that, it was entertaining.
I normally don't read too many mysteries written before the 90s, but when I was looking for more Japanese mystery authors Seishi Yokomizo's name kept coming up. I was hooked pretty quickly and ended up buying the rest of the books in the series! This is the shortest one so I'm excited to see the details he gets into as this seemed so complicated, but short.
