Song of the Nightingale

Philippe, the narrator of this tale, is secretary to Count De Lorenzo, and lover to the Count's young wife. He is tasked with buying young boys from poor villagers, having them castrated and taking them to Florence to be taught to sing as castrati.
The parents are told that their sons are especially blessed with their wonderful voices and they do not object to the boys making a physical sacrifice in order to thank and praise the Lord; nor to the bag of gold they are given in exchange.
The boys are innocents, victims of circumstances beyond their control. Surely they can have nothing to do with a barber's mysterious death, or the suicide of an abusive Jesuit priest?
This is a tale of passion, revenge, guilt, regret, loss and redemption.
