Read in Korean translation A new addition to the regional public library Korean collection
Interesting to note the author is 3rd generation Korean Japanese- not sure whether his Korean name (which was shown on Korean version) is literal translation of his Japanese name.
The story is very clever, also reflecting social issues- reminded me of '재수사' by 장강명
So unbelievably tense and well written. I think a lot of the societal stress that the villain highlights is well explored and both unique to Japanese culture and also universal in a way.
