Ryton continued his 'royal-theme' in 1981 with the comedy (co-written with Ray Cooney), "Her Royal Highness", about a double having to stand-in for Lady Diana Spencer when she loses her nerve and disappears, one week before the Royal Wedding. It ran successfully at the Palace Theatre in London's West End from 1981-82. With "Crown Matrimonial (1972)", Ryton achieved an historical first - the serious portrayal of a living member of the Royal Family (Queen Elizabeth, The Queen Mother) on the stage. The play was Ryton's most successful work. - from Amzon
