Plot summary
The Earl of Clan Gordon (Stewart Arnott) kidnaps Queen Mary in the hopes of forcing her to marry his son George Gordon, 5th Earl of Huntly. Mary escapes, and foils John Knox's attempts to manipulate the situation. Queen Leeza ( Anastasia Phillips ), eldest daughter of Catherine and wife of Philip II of Spain, arrives at French court, where her pro-Spain policies cause her to clash with Queen Mother Catherine and Princess Claude. Princess Claude discovers that Martel was behind Leith's death, and works with her mother to stage Martel's "suicide". Gideon discovers that John Knox was behind the assassination attempt on Queen Elizabeth, and informs both Queen Elizabeth and Queen Mary.
Despite James's concerns, Queen Mary wants to marry Darnley ( Will Kemp ), an English Catholic with a claim on the English throne. Darnley's mother, Lady Lennox (Nola Augustson), has been working behind Elizabeth's back for the match, but Darnley promises Queen Elizabeth that he will stay away from Scotland if she arranges for him to marry Keira (Sara Garcia), the woman he loves. Greer arrives in Scotland to comfort Queen Mary over Lady Lola's death.
