In 1960 Penguin Books were prosecuted when they tried to publish Lady Chatterley's Lover unexpurgated for the first time. What followed was the most talked-about obscenity trial of the twentieth century, which resulted in a 'not guilty' verdict. Penguin's successful defence of the book's literary merit was a victory of free speech, and made Lawrence's story of the affair between a married woman and her gamekeeper an instant bestseller.
