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.
