A Japanese husband announces that he will follow through on his promise to divorce his wife because she has not borne him a child within their first year of marriage. He already has a mistress lined up when he dies of mysterious causes. Naturally, the spurned wife is the lead suspect but she is hundreds of miles away when her husband succumbs. The Japanese investigative team consists of a seasoned lead, Tokyo Policeman Kusunagi, who is insensitive about his perceptive, young, female recruit. Together they are aided by Professor Yukawa, a heady and utterly cranky academic. The reader on this audio book brought the well developed characters to life and though the ending was mildly anticlimactic the story itself was fully engaging.
