The Pillow Book of Lady Wisteria — Laura Joh Rowland

FROM A REMOTE, EXOTIC WORLD...
Sano Ichiro, Most Honorable Investigator of Events, Situations, and People, awakens from a turbulent dream into a real-life nightmare. Lord Matsudaira Mitsuyoshi, the shogun's cousin and heir, has been murdered after a night of debauchery in the city's pleasure quarter...

A DANGER ALL TOO CLOSE TO HOME...
The matter requires Sano's personal attention-more personal than Sano at first imagines. For he soon discovers that Mitsuyoshi's companion for the evening was none other than the alluring Lady Wisteria, a woman whom Sano himself once knew intimately before he was married to his beloved wife, Reiko. But the memory of Wisteria still stirs him, and it is with both dismay and relief that he learns she has vanished along with her pillow book, a diary that may contain valuable clues. The circumstances trouble him, as does the possibility that he and Wisteria might meet again with dangerous consequences. . .
