In a novel with echoes of Noble House, The Alchemist, and Gorky Park, Japan’s preeminent detective-Samurai, Sano Ichiro, returns to risk his honor and life. In 1690 Nagasaki, Sano must crack his most sensitive case yet as he sets about to discover who killed a Dutch trader whose body has washed up on the shore of a small island famed for its barbarians.
