First in a trilogy about Catherine de Medici, Madame Serpent briefly covers Catherine's childhood and then focuses on the years of her marriage to Henry, Duke of Orleans, later King Henry II of France. The wars and religious controversies of the period are backdrops to Catherine's personal story and her transformation from vulnerable child to scheming woman. A harsh upbringing impresses upon her the need to control her emotions. Forced into a political marriage at age fourteen by her uncle, Pope Clement VII, she found a warm welcome from her father-in-law, King Francis I, but not from her young husband. Throughout Henry's life, his much-older mistress, the famously beautiful Diane de Poitiers, publicly assumed the first place in his affections.
Plaidy holds readers' sympathy for Catherine by portraying the almost inhuman cruelties she suffered as a child and the humiliations heaped upon her by the husband whose affection she craved and the rival who delighted in assuming the role of de facto queen. If Catherine's abiding love for Henry, despite his emotional cruelty to her, requires some suspension of disbelief, her growing hatred for Diane does not. And if Catherine's rapid transformation into a woman who "does not weep" but "makes plans" is often chilling, she remains fascinating in her refusal to crumble or allow herself to be crushed. The plot moves steadily forward without excursions into political affairs, except for occasional brief passages directly pertinent to Catherine's emotional life. There is genuine history here, but it is a history of individuals rather than of nations.
The great appeal of Madame Serpent is as a captivating tale of a glitteringly wealthy woman of status and, ultimately, power who is impossible to envy. The story offers a lesson, as well, in the ripples of harm that may spread outward from cruelties practiced upon the weak - who do not always stay weak. (1951; 387 pages in 2012 Touchstone edition)
