 Furthermore, she has been poisoned towards him by slanderous lies spread by Darcy's nemesis, George Wickham, and is convinced that Darcy is "the last man in the world whom [she] could ever be prevailed upon to marry".Heartbroken by Elizabeth's refusal and stunned by the depth of her dislike towards him, Darcy decides to put Elizabeth behind him and leaves Rosings, but not before writing her a letter explaining the true history between himself, Wickham, and his sister Georgiana, and attempting to justify his actions regarding Bingley and Jane Bennet.Upon his return to London, however, Darcy begins acting in an increasingly uncharacteristic and erratic fashion towards his friends and Georgiana, culminating in his unwise acceptance of an invitation to a party held by Lady Sylvanie Monmouth, who attempted to seduce him at Norwycke Castle.
