Rei Shimura's life goes through another round of failures: a friend left Japan and the antique business is limping on both legs. In addition, Aunt Norie literally forces her to enroll in the Kayama Ikebana School, one of the best in Tokyo. Rei isn't good at arranging bouquets because she's only half-Japanese, but her talent as a detective comes in handy when a school teacher is found dead with garden shears in her throat.
