The lady,Grace Elliot, is an expat Scot who's living in France at the time of the French Revolution. She speaks perfect French(as does the actress,Lucy Russell).What an amazing feat for a British actress!The Duke is the Duke of Orleans,cousin to King Louis, but Republican and in opposition to the Monarchy.This is at the time of the Terror when lots of Aristocrats lost their heads to the guillotine. Grace is an ex-lover of the Duke, but they are still good friends and he writes to her and visits her. He is forever telling her to go as she is not safe. She prefers to live in France at this time. Rohmer makes an elegant stab at a historical drama and cleverly uses painted backdrops, and does a good job on the interiors and the clothing, all hand-stitched. He comes at the subject using Elliot's journals, from a Royalist point of view(that is Grace's). She and the Duke, sometimes have disagreements e.g. about supporting the King, but the Duke prefers them with her, than with his son, who rebels against him dangerously. The actors performed against blue screens and the perspectives of streets and buildings were painted& projected on to the screens.This perfection of artifice, works and creates the atmosphere of 18th century France. Lucy Russell, convinces with her eloquent French, and she has a Gainsborough-like animation, natural with the French and the artifice.Dreyfus is a good counterpart to her, as steady ,loyal and charming.She has a close shave with the Committee of Justice, but is exonerated.However Dreyfus meets a different end.French critics opposed Rohmer's politics, but lauded the technical feat of pulling off such a subject with limited means.Most of all, as it was based on a real journal, I loved the personal angle on it.
