Monsieur Hawarden (1968)

A woman disguises herself as a man to avoid prosecution for murdering her lover fifteen years ago. She is the last living member of a wealthy Vienna family, and has spent the years after the murder traveling Europe with her female servant. Her travels provide her with an anonymous cloak that allows her freedom of movement but little peace of mind. Nearing middle age, the guilt and weariness of an empty life has her contemplating suicide as the only way out of her dilemma.
