DH Lawrence biographer John Worthen discusses DH Lawrence's retreat to Cornwall following the controversy over his novel The Rainbow and the horrors of the First World War. Worthen talks to fellow Lawrence scholars Fiona Becket, Mark Kinkead-Weekes, and Christopher Pollnitz about the impact of this period on Lawrence's life and work. Lawrence may have loved Cornwall, and completed Women in Love - one of his best novels - there, but the violence of the war eventually caught up with him, and he and his wife were expelled on suspicion of spying in October 1917. This experience surfaced in his later Novel Kangaroo - in a the chapter which he called The Nightmare.
