Seichō Matsumoto was a well respected Japanese novelist in the detective novel genre. The strength of his stories lays not in the murder mystery he could offer, but his sharp observation and understanding of human nature and social situations.
Well, so far I don't find the short stories from this collection terribly interesting, but it's still well written.
PS: I admit it...I didn't finish the whole book. I lost interest 3/4 in.
