In 1769, Monsieur Chevalier D'Eon de Beaumont, spy, diplomat, decorated Prussian war hero and international bon viveur emerged from his London apartments in female attire and spent the rest of his life as the woman she now said she always was. Proudly wearing the Chevalier d'Honneur medal on her flowing robes, she outraged and antagonised the whole of the French aristocracy, spending astronomical amounts of English Guineas and running up huge diplomatic debts fighting for her very existence and acceptance in an unforgiving world. This bizarre, true story is challenging, emotional, painfully funny and provocative; reaching deep into our perceptions of normality, acceptability and promiscuity, setting an historical thumbprint on the way we live our lives in an "enlightened" 21st Century world.
