'I've started to wonder, what if it isn't my sisters at all.It's me... Some wicked, hateful part of me that thinks some human beings are superior to others, thinks I'm superior.'The glamorous Mitford sisters once cut a swathe through pre-war high society.But as fascism rises and political storm clouds gather, the bonds of sisterhood are threatened by new and treacherous desires. Nancy aspires to be a celebrated novelist, Diana and Unity fall for the dangerous, charismatic leaders of the far right in Britain and Germany, and Debo sets her cap at a Duke.Meanwhile, Decca crosses continents in her own passionate pursuit of love – but can she ever escape her sisters and her past?Compelling, touching and witty, Amy Rosenthal's play The Party Girls explores the true story of a family riven by political extremism, and asks what it takes to stay true to your beliefs.It premiered in 2025 at the Marlowe Theatre, Canterbury, before touring nationally.
