Paul Doherty The Cup of Ghosts (Mathilde of Westminster Trilogy, Book 1)

By 1322, Mathilde of Westminster was considered the finest physician in London. But in her years as lady-in-waiting to Princess Isabella, she was drawn into the murky politics of the English court, where sudden, mysterious death was part of the tapestry of life. Many years later, Mathilde looks back and chronicles her turbulent life. With her sharp, suspicious intellect ready to distinguish between a fatality and an unnatural death, Mathilde is confronted by a host of chilling murders. The source of these horrors is the fierce political rivalry between Philip of France and Edward of England. This manifests itself in a series of gruesome killings, one of which actually took place during Edward II's Coronation, when a knight of the Royal Household, Sir John Baquelle was crushed to death.
