The Queene's Cure (Elizabeth I #4)
Karen Harper

Elizabeth’s fear that the counterfeit corpse is a harbinger of tragedy comes to fruition when ever more terrifying transgressions penetrate the very heart of her royal precincts. With the help of her Privy Plot Council , Elizabeth resolves to unmask a murderer who wears a false face and is beset by the vilest humours of the soul. But when she herself falls ill, an entire realm is caught in the grip of a treasonous conspiracy...as the indomitable young monarch fights for her life, her realm, and her rightful crown.
