"The Warden" is the first novel in "The Chronicles of Barsetshire" series and was also Trollope's first breakthrough novel.
It is the story of a devoted priest, beloved by all who know him, and who is racked by fear that he is accepting money to which he is not entitled. His antagonist is his prospective son-in-law John Bol, whilst his (somewhat unwelcome) ally is the characterful Archdeacon of Barchester, Dr. Theophilus Grantly.
Based on real events that rocked the mid-nineteenth century and the Church of England, Trollope uses these historical events as a background to explore love, relationships, and morality.
