Setting and cast
The action takes place on the sea-swept outskirts of Lower Wessex, around Castle Boterel and Endelstow Vicarage, in a landscape of cliffs, gulls and ruined church-architecture. Principal figures include Elfride Swancourt, an impressionable young woman; her father, Christopher Swancourt, the vicar; Stephen Smith, a gentle, provincially bred architect’s assistant from London (son of John Smith, Lord Luxellian’s master-mason); Henry Knight, an urbane critic and man of letters; Lord and Lady Luxellian; Mrs Charlotte Troyton (later Mrs Swancourt); and a circle of villagers (Mrs Jethway among them) who register social pressure and consequence.

Premise and narrative arc
Against the vogue for church “restoration,” Mr Swancourt invites Stephen to survey St. Agnes. Stephen’s unexpected youth and refinement attract Elfride; through shared music, walks, chess and intimacies a mutual attachment grows. Class tensions surface when Mr Swancourt learns Stephen’s parentage and forbids the match. In panic Elfride and Stephen briefly elope to London; she flees the metropolis and returns home; Stephen departs for India to make his fortune, later achieving success and sending money home.

Intervening relationships and crises
Henry Knight, first encountered as the reviewer of Elfride’s anonymously published medieval romance, appears in person: ironic, morally incisive, and increasingly intimate with Elfride during Stephen’s absence. His presence complicates Elfride’s loyalties. A sequence of clandestine meetings, misread correspondence and social manoeuvres escalates tension. A climactic seaside episode—Knight endangered on a cliff and rescued by Elfride’s resourceful tearing of linen into a rope—precipitates intimacy and realigns her affections toward Knight. Mrs Jethway’s accusatory letter, prepared before her death under a collapsing tower, reaches Knight and intensifies his jealousy; his demand for candour produces estrangement and continental travel.

Resolution and consequences
The mid- to late-novel stages leave earlier tensions unresolved: Stephen abroad but financially committed, Knight newly in love yet jealous, and Mr Swancourt recently married to Mrs Troyton and socially elevated. Subsequently Elfride’s life takes an unexpected social turn—she becomes associated with Lord Luxellian, is married abroad, and dies; her coffin and coronet are returned to the locality. The final ironies leave both Knight and Stephen bereft, confronting ambiguity, regret and the limits of moral judgment.

Themes, motifs and style
The narrative examines class, taste, gendered expectations, and the collision of provincial sentiment with metropolitan culture. Recurrent motifs—cliffs, church vaults and tombs, letters, funerals—materialize themes of risk, secrecy, mortality and reputational economy. Psychological realism and saturnine irony govern the narration: characters are mixed in motive and imperfect in self-knowledge, and chance (accidents, delayed or misdirected letters) crucially shapes destinies. Landscape and ruined architecture function as emblematic backdrops to intimate crises, sustaining an inquiry into how private frailty and social structure conspire to determine human fate.
