Visceral really does describe this book. There were parts I had to close my eyes because the visuals that the words created were too vivid. There's no real mystery as to who did it. The mystery lay in the reasons that three women would take on a gruesome task to help cover the murder committed by a fourth when all they really had in common was a job that was degrading and difficult in itself.Why did I find myself rooting for these women even though their actions were horrific and not one of them was truly likable? It might be that each woman has taken her share of neglect and abuse and the measure of freedom each obtained, if only briefly, through said actions. We also see a Japan that few fans of it want to see. How there is little equality and that most people eke out a living on a knife edge that any small thing can tip them off and lead to ruin. How a consumer driven society has led to debts that are literally collected by thugs.I did find the ending a bit cryptic and that kept me from giving this book a solid 5 stars. Kirino is a powerful writer and one I will read more by.
