In "A Pair of Blue Eyes," Thomas Hardy weaves the tale of Elfride Swancourt, a young woman torn between two lovers in a story that predates modern romantic dramas. Elfride finds herself navigating the complexities of love and social expectation when she falls for Stephen Smith, a socially inferior architect, only to be later courted by the sophisticated Henry Knight. Set against the rugged backdrop of the English coast, Hardy explores themes of innocence, jealousy, and the constraints imposed by societal class, marking the novel with his signature blend of romance and tragedy.
