The Mitfords is a superb one-woman show by Emma Wilkinson Wright who focuses her attention on Unity, Diana and Jessica. In the early 1930s, Unity became Hitler’s lover and she lived in a luxurious Munich apartment confiscated from a wealthy Jewish family. The Führer, whom she nicknamed ‘Wolfie’, gave her the pearl-handled revolver with which she shot herself in the head shortly after Britain’s declaration of war.
