'You haunt me everywhere.' So wrote Edward Burne-Jones to Frances Graham, his muse for the last 25 triumphant years of his life: 'I haven t a corner of my life or my thoughts where you are not''. He drew her obsessively, included her in some of his most famous paintings, and showered her with gifts. Even when she betrayed him to marry, he would return to her. To him 'all the romance and beauty of my life means you.' This is the first biography of his muse.
