I thought this one was OK, but not terribly exciting. It’s an easy read with some interesting insights into post-war Japanese culture, but the characters aren’t particularly well drawn or realistic and I never felt invested in them. In particular, the Kito sisters are shallow stereotypes who are only there to drive the plot forwards. There are lots of info-dumps as characters tell the detective what has gone on which get a bit boring. The summing up takes about 20 pages. I’m not itching to read the other books in the series.
