Emperor's pearl (The University of Chicago Press)

It all begins on the night of the Poo-yang dragonboat races in AD 699: a drummer in the leading boat collapses, and the body of a beautiful young woman turns up in a deserted country mansion. There, Judge Dee - tribunal magistrate, inquisitor, and public avenger - steps in to investigate the murders and return order to the Tang Dynasty.In "The Emperor's Pearl", the judge discovers that these two deaths are connected by an ancient tragedy involving a near-legendary treasure stolen from the Imperial Harem one hundred years earlier. The terrifying figure of the White Lady, a river goddess enshrined on a bloodstained altar, looms in the background of the investigation. Clues are few and elusive, but under the expert hand of Robert van Gulik, this mythic jigsaw puzzle assembles itself into a taut mystery.
