Out

It is extremely difficult to convey the range of emotions evoked in words, once you've finished this masterpiece - Kirino is simply astounding, beyond words.
It looks like a simple enough plot at first glance - in a fit of rage, a staid Japanese housewife working the night-shift at a lunchbox factory murders her husband in a fit of rage at his emotional and physical abuse. She approaches her dependable co-worker for help, who ropes in two of their mutual acquaintances for disposing the body. They are determined, but inexperienced - and the detectives and yakuza (the Japanese mob) is baying for blood.
But what blew my mind away is the sheer twists this story takes, with the narrative taking you along for a roller-coaster ride that you never want to end. As far as characters go, they are so developed, that they almost seem to protrude through the pages. Masako, the aforementioned dependable co-worker who is approached for help, is so brilliantly written that you sometimes feel that she is based on a real woman, somewhere out there in the Japanese suburbs.
The pacing, characters, narrative - all of it is perfectly blended. And the plot elements, uncommon in Japanese fiction (assault, murder, prostitution) enhance the narrative rather than detracting from it. It is exhilarating from start to finish, and should not be missed - every word written in praise for it will be a disservice. Natsuo Kirino's tour de force will haunt me for a long, long time to come.
