Dragon's King Palace

In Rowland's eighth engrossing 17th-century Japanese mystery (after 2002's The Pillow Book of Lady Wisteria), Sano Ichiro, the shogun's Most Honorable Investigator of Events, Situations and People, is roused in the middle of the night when the shogun's mother and Sano's wife, Reiko, are kidnapped en route to Mount Fuji and their escort slaughtered. The crisis is exacerbated by the identities of the two other abductees: the wife of Sano's primary rival, the chamberlain Yanagisawa, the real power behind the shogun; and the pregnant wife of Sano's chief assistant.
