It is 1948 and Britain is struggling to recover from the Second World War. Half French, half English, Marguerite Carter, young and beautiful, has lost her parents and survived a terrifying war, working for the SOE behind enemy lines. Leaving her partisan lover she returns to England to be one of the first women to receive a degree from the University of Cambridge. Now she pins back her unruly auburn curls, draws a pencil seam up her legs, ties the laces on her sensible black shoes, belts her grey gabardine mac and sets out towards her future as an English teacher in a girls' grammar school. For Miss Carter has a mission – to fight social injustice, to prevent war and to educate her girls. Through deep friendships and love lost and found, from the peace marches of the fifties and the flowering of the Swinging Sixties, to the rise of Thatcher and the battle for gay rights, to the spectre of a new war, Sheila Hancock has created a powerful, panoramic portrait of Britain through the life of one very singular woman.
