In this novel, Fowles is interested in the literary genre of the
nineteenth-century romantic or gothic novel and succeeds in
reproducing: typical Victorian characters, situations and dialogue,Victorian attitudes towards women, economics, science and philosophy. But his perception of the genre is touched with typical twentieth-century irony. His thematic concerns range from the relationship between life and art and the artist and his creation to the isolation that results from an individual struggling for selfhood. Major Characters
Sarah Woodruff - She is also referred to as "Tragedy" or "The
French Loot’n’nt’s Tenant’s Hore." She is the scarlet woman of
Lyme, the outcast dismissed by society because of her affair with a
French sailor, she is the mysterious pariah of the story. Her character is that of a mysterious or evil woman commonly found in a Victorian novel. She is almost totally rejected by the small society in Lyme, and relies solely on the charity of Miss Poulteney. This position is an interesting one, because it is more or less a choice made by Sarah herself. She is a virgin when Charles meets her, and the story of the lieutenant is not quite correct. Sarah is trying to shape her own identity, and in doing so, she has to reject the rigid conventions of society. She chooses the role of the martyr, suffering for a set of ideas about how things could have been. Even though she is the character mentioned in the title, Charles seems to be a more likely protagonist in the story. Sarah does not develop in any remarkable way, as her conception of her own identity is more or less satisfying. She is able to choose conscously her own role, and chooses knowingly what consequences it may have, in contrast to Charles, who suffers under the unwritten and invisible conventions of society.
