The Way of the Traitor (Sano Ichiro, #3)

The year is 1690. The place is Nagasaki, Japan. But the motives for murder are the same as they always have been and always will be: lust, greed, and political expedience. When the disfigured body of a prominent Dutch trader is found washed ashore, there are few leads and too many enemies. Sano Ichiro is dispatched to find the killer. But as Sano gets drawn more deeply into the intrigue and deceit that surround the dead Westerner's activities, he finds that nothing it as it seems, and no one can be trusted.
