This has rave reviews on Goodreads but I didn't care for it. All the characters were pretentious, arrogant, and self absorbed: the aspect of deciphering the chess game was way too detailed and took up far too much of the story; and the ultimate culprit (and the reasons behind this villain's killing spree) was unbelievable. Some of my complaints may be down to translation but I probably won't read more of this author just the same.
