The perfect childhood and the failure of utopian experiments in living in Edwardian England were explored by AS Byatt in her 2009 novel The Children's Book. In this conversation with Matthew Sweet recorded in that year, they discuss her writing life, mythologising childhood and her meetings with Iris Murdoch, about whom she wrote two critical studies. A lecturer in English literature, AS Byatt's books drew on a wide range of reading and visiting art galleries and museums. In 1990 she won the Booker prize for her novel Possession.
