Jade Dragon Mountain by Elsa Hart
This is an outstanding mystery debut, set in southwest China in 1708. Exiled imperial librarian Li Du visits Dayan, near the Tibetan border, and reports to the local magistrate, his cousin Tulishen. Li Du learns that the emperor is coming to Dayan for a festival to celebrate a solar eclipse, and the preparations are considerable, including building a new pagoda. A few foreign visitors are in Dayan, including two Jesuits and a representative of the East India Company. When an astronomer dies suddenly, Li Du is useful as a translator and wants to investigate the death, although the magistrate would rather cover it up. The mystery is clever, but I especially enjoyed the variety of well-drawn characters, and the richly detailed setting. I hope Li Du will have many more adventures, and I think readers of mysteries or historical fiction will thoroughly enjoy reading this book.
