Unravelled explores the history of a family which was completely concealed from the author throughout her life, and only began to be revealed after her mother died. A clash of cultures - exceedingly grand aristocrats meet Jewish rabbinical scholars - with consequences that reverberated down the generations. It tells the story of the unravelling of a mystery, and encompasses an extraordinary cast of characters, from the wicked Earl of Erroll, of White Mischief fame, and twenties socialite Mimi Wimborne through to the author, artist, and intellectual John Berger. In the telling of the story, the author explores themes of exile, love and loss and asks why the talented but flawed women of her family were so comprehensively written out of history.
