Ooo thanks for the recommendation! Definitely adding this to my list. I love novellas and I really enjoyed Temple of the Golden Pavillion and Confessions of a Mask, so I've been wanting to check out more Mishima.

While it doesn't quite hit the OPs threshold, I love talking about this book:

Devils in Daylight by Junichero Tanizaki. 1,070 ratings on GR. This novella coming in at 98 pages was written in 1918 which is why I think it counts. A short murder mystery with themes of voyeurism and obsession and so much more that meets the eye. A really cool observation of films influence on writing too. When I first read it, I thought it was written in the 60s, but for it to be 1918 I was totally blown away it felt so ahead of its time.
