Japanese-American Rei Shimura is a 27-year-old English teacher living in one of Tokyo's seediest neighborhoods. She doesn't make much money, but she wouldn't go back home to California even if she had a free ticket (which, thanks to her parents, she does.) Her independence is threatened however, when a getaway to an ancient castle town is marred by murder. Rei is the first to find the beautiful wife of a high-powered businessman, dead in the snow. Taking charge, as usual, Rei searches for clues by crashing a funeral, posing as a bar-girl, and somehow ending up pursued by police and paparazzi alike. In the meantime, she manages to piece together a strange, ever-changing puzzle-one that is built on lies and held together by years of sex and deception.
