Maybe not everyone's kind of book, but I found this book very interesting.
Basically it is about a Japanese Captain who in the war has orders to kill an American airman.
Once the war is over he is hunted down as a war criminal.
The irony of the book is that he killed one man but the Americans killed thousands of innocent people with their incendiary bombs and of course the bombs dropped on Hiroshima and Nagasaki.
It is a book that stays with you after reading and makes you think about the injustice of war, thus the title.
