If you think you know Susannah Constantine you may be surprised to learn the truth. That she made her name as a 'style guru' from What Not to Wear is actually the least interesting thing about her. Hers is a tale full to the brim with extraordinary anecdotes. From lavatory dramas with Princess Margaret, to behind-the-scenes power struggles between Thatcher and the Queen at Balmoral and eye-opening sex-club etiquette with pop royalty - her social landscape has been nothing, if not varied. But appearances are deceptive and beneath it all, life had a darker side: her mother's bipolar disorder, her father's inability to cope and her own subsequent alcoholism. Somehow she had to forge her own life, away from the expectations of others.
