Necklace and Calabash

A.D. 668
Due to its proximity to the Water Palace, the summer residence of the Emperor's favorite daughter, Riverton lies within a Special Area administered by the military. To Judge Dee, returning to his district of Poo-yang, the peaceful town promises a few days' fishing and relaxation. But it is not to be. A chance meeting with a Taoist recluse, a gruesome body fished out of the river, strange guests at the Kingfisher Inn, a princess in distress--before long the judge is facing one of the most intricate and baffling mysteries of his career.
