AL Kennedy and David Sedaris on matters of the heart

Tom Sutcliffe talks to AL Kennedy about her latest collection of short stories of love and hurt. The poet Lavinia Greenlaw retells the tragic love story of Chaucer's Troilus and Criseyde. The philosopher Simon Blackburn unpicks the idea of self-love from the myth of Narcissus to today's tv hair adverts: 'because you're worth it', while the humorist David Sedaris uses his own life and loves as the focus of his writing.
