This week's castaway, Mary Archer, admits to being basically a private person, happy to find refuge in her work as a scientist and in her love of music. In conversation with Sue Lawley, she looks back on her life and career, and also recalls the two crises involving her husband, Jeffrey. In her choice of records to take to the mythical island, she shows a preference for choral music.
