Richardson appears in later series as characters not explicitly stated as being descendants of Elizabeth I (but may share common ancestors with her). In the fifth episode of Blackadder the Third, she plays Amy Hardwood, the seemingly delicate industrialist's daughter whom the Prince Regent courts to get out of serious debt, later revealed as a highwayman, the Shadow; and in the episode General Hospital of the fourth series, she plays Nurse Mary Fletcher-Brown who enjoys a fling with Blackadder, before being falsely accused of being a German spy.
