Plot summary
King Francis and Queen Mary learn that King Antoine is thinking of allying with their enemy, Queen Elizabeth of England as he believes that Bash had killed his and Prince Louis's elder brother, Prince Marcus, during the Italian Wars, and wants vengeance, either by killing Bash or seducing Lady Kenna. Bash investigates a man (Greg Calderone) who had supposedly returned to the Underworld by a mysteriously woman in white. Queen Catherine has a prophetic vision of her eldest son's death. However, King Francis, Queen Mary and the royal doctors attribute this to syphilis, which she has symptoms of.
Queen Catherine, with Lord Narcisse's help, discovers that she is actually being slowly poisoned by the pages of the late King Henry's old Bible, which they conclude was directly responsible for gradually turning King Henry insane. Queen Mary attempts to renew her relationship with King Francis but finds it too difficult, so she gives him permission to find someone new to love.
