Recorded in A Room for London, the creative / living space in the shape of a boat on top of the Queen Elizabeth Hall on the South Bank of the Thames, Open Book explores the impact the city has had on literature - from Chaucer and Dickens to Martin Amis and Peter Ackroyd; the themes it evokes and why it creates such a diverse backdrop to novels. Mariella Frostrup is joined by novelists who've all been charmed by London - Will Self, Amanda Craig, Dreda Say Mitchell and Ben Aaronovitch.
