With its four-letter words and its explicit descriptions of sexual intercourse, Lady Chatterley's Lover is the novel with which D.H. Lawrence is most often associated. First published privately in Florence in 1928, it only became a world-wide best-seller after Penguin Books had successfully resisted an attempt by the British Director of Public Prosecutions to prevent them offering an unexpurgated edition. The famous 'Lady Chatterley trial' heralded the sexual revolution of the coming decades and signalled the defeat of Establishment prudery.
