West Yorkshire, 1904. When newly graduated nurse Ruby May takes a position looking after the children of Charles and Lilian England, a wealthy couple from a powerful dynasty of mill owners, she hopes it will be the fresh start she needs. But as she adapts to life at the isolated Hardcastle House, it becomes clear there's something not quite right about the beautiful, mysterious Mrs England. Ostracised by the servants and feeling increasingly uneasy, Ruby is forced to confront her own demons in order to prevent history from repeating itself. After all, there's no such thing as the perfect family - and she should know. Simmering with slow-burning menace, 'Mrs England' is a portrait of an Edwardian marriage, weaving an enthralling story of men and women, power and control, courage, truth and the very darkest deception.
