The Heir of Redclyffe (1853) was the first of Charlotte M. Yonge's bestselling romantic novels. Its religious tone derives from the High Church background of her family and from her friendship with a leading figure in the Oxford Movement, John Keble, who closely supervised the writing of the book. The germ of its plot was suggested by her friend Marianne Dyson. According to J. B. Priestley The Heir of Redclyffe was "the most popular novel of the whole age…Its popularity left Dickens and Thackeray far behind." The Heir of Redclyffe tells the story of the Byronic Guy Morville, heir to the Redclyffe baronetcy, and his cousin Philip Morville, a conceited hypocrite who enjoys an unwarrantedly high reputation.
