The Poisoned Crown by Maurice Druon

This book continues the story of the end of the Capetian kings in France. Philip the Fair, son of Saint Louis, has died and passed the crown to his somewhat incompetent son, Louis X, le hutin, who has just had his estranged wife strangled so that he can remarry. But the kingdom is full of plots, and Louis's inability to gauge his friends and enemies may be his downfall. This book is another enjoyable entry in the series.
