Born Hon. Alice Clare Antonia Opportune Cooper, she is the only daughter of The 2nd Viscount Norwich (better known as John Julius Norwich) and his first wife, Anne (née Clifford), and a granddaughter of Lady Diana Cooper. She has a brother, the Hon. Jason Charles Duff Bede Cooper, and a half-sister, Allegra Huston, the only child of Lord Norwich and Enrica Soma Huston, the estranged wife of American film director John Huston.
Cooper attended the French Lycee, the Convent of the Sacred Heart in Woldingham and Camden School for Girls. She then went to St Hugh's College, Oxford and obtained a degree in English language and literature. In July 2015, she was awarded an honorary doctorate from the University of York.
Cooper's first book was a collection of the letters of her grandmother, Lady Diana Cooper.
When her biography of Patrick Leigh Fermor appeared in 2012, it was serialised on BBC Radio 4. It was followed in September 2013 by The Broken Road, effectively the third volume of Leigh Fermor's memoir of his walking trip from the Hook of Holland to Istanbul in the 1930s.
