Margaret is a respected biographer of Thackeray, Elizabeth Barrett Browning and Daphne du Maurier but in recent years her subject has increasingly been her own family. In Hidden Lives, in 1995, she traced three generations of the Cumbrian working class through her mother's and grandmother's stories, and, in her hands, these ordinary, rather uneventful lives became utterly compelling. Three years later, in Precious Lives, she turned to her father and contrasted his death, at 96, with the early death from cancer of her sister-in-law, Marion, to whom she was very close. It is a raw, distressing book. Hunter, when he read it in Cumbria, left her a note: "Have read Precious Lives today. Have gone down to lake to drown self."
