Jennifer Egan won the Pulitzer Prize for her novel A Visit From The Goon Squad. Her new book Manhattan Beach is set largely during the Second World war, her heroine is the first ever female diver employed to mend warships. She talks to Mariella Frostrup about turning her hand to historical fiction, and her literary interest in twins. Also on the programme, Jen Campbell calls for better depiction of people with disabilities in fiction; biographer Helen Smith talks about Edward Garnett - man of letters and supportive editor to DH Lawrence and Joseph Conrad among others and Adam Haslett reveals the book he'd never lend.
