Nagasaki, 1690. Sano Ichiro arrives in Japan’s tightly controlled international port, where Dutch merchants are confined to their island settlement and every exchange with foreigners is treated as a potential act of treason. When a Dutch trader is found murdered, Sano is assigned a case that local officials would prefer to suppress.
Evidence of smuggling, corruption and clandestine contact draws Sano into conflict with the governor, interpreters and merchants who profit from the closed trading system. To identify the killer, he must distinguish commercial crime from espionage while avoiding an accusation that could destroy not only himself but everyone associated with him.
