The author of the book, Pierre Chevalier (09/08/1913 - 04/10/1998), a recognized historian, based on a scrupulous analysis of authentic documents, creates a completely new, different from the traditional image of Henry III, the “Shakespearean” prince of French history of the 16th century. His remarkable, contradictory nature and tragic fate, even for an era of religious unrest, served as fertile material for many historical and biographical interpretations.
