Sarah Fielding was one of the most respected women authors of her generation and a key figure in the development of the novel. She was admired especially by Samuel Richardson, who famously commented that her ‘knowledge of the human heart’ was greater than that of her brother, the novelist Henry Fielding. This edition revives The Countess of Dellwyn, the only one of Sarah Fielding’s major works not previously available in a modern scholarly edition. The novel is satirical and didactic, taking as its targets fashionable life and modern marriage (and scandalous divorce) and narrated with acerbic wit by its anonymous third-person narrator. This edition benefits greatly from Gillian Skinner’s editorial work and it is a book that will be of great interest to researchers into the eighteenth-century novel and women’s writing of the period worldwide.
