Doctor Thorne, considered by Trollope to be the best of his works, is a telling examination of the relationship between money and morality.
It recounts the story of the son of a bankrupt landowner, Frank Gresham, who is intent on marrying his beloved Mary Thorne despite her illegitimacy and apparent poverty. Frank's ambitious mother and haughty aunt are set against the match, however, and push him to make a good marriage to a wealthy heiress. Only Mary's loving uncle, Dr Thorne, knows of the fortune she is about to inherit - but believes she should be accepted on her own terms.
