"Love-Letters Between a Nobleman and His Sister" by Aphra Behn is based loosely on an affair between Ford, Lord Grey of Werke, and his wife's sister, Lady Henrietta Berkeley, a scandal that broke in London at its time. Silvia, a young beautiful woman, is wooed by Philander, her brother-in-law, in an "incestuous" affair. The plot is about the slow decline of honor and nobility, as well as the psychological effects of love.[9] The novel is told through letters between Silvia and Philander that give a deeply personal nature to the affair.
