Fourth in the series that features Yashim the Eunuch who is also a special investigator for the Sultan of the Ottoman Empire. Set in the declining years of the Ottoman Empire and the rule of a new sultan, Yashmin has yet the mystery of the murder of a Russian agent whose body was discovered in the well of a Greek Orthodox monastery. With his usual brilliance, Yashmin is able to unravel this mystery as well as several others. These books are a wonderful snapshot of the culture and intrigue of this time period. Yashmin is a delightfully entertaining sleuth who also a fantastic cook. I never finish one of these books without wanting to taste one of his dishes.
