England's longest-reigning monarch is an enigma. In public, she confines herself to optimistic pieties and guarded smiles; in private she is wry, funny and an excellent mimic. Here one of Britain's leading broadcasters recounts her childhood, her accession to the throne and her unswerving devotion to duty, and offers a touching glimpse of this 'anti-celebrity, a woman happiest in scarf, old coat and rubber boots, out with her dogs or horses'.
