Oswald Warkworth

Oswald Warkworth is a suitor to Arabella Tallant and friend to Sir Geoffrey Morecambe and Lord Fleetwood. He thinks that Lord Bridlington's attempt to dispel rumors of Arabella's supposed wealth is merely an attempt to get rid of his rivals, and he thinks that it is impossible for Arabella to be a merchant heiress because of her genteel behavior. He attends several events also attended by Arabella, such as her evening party, Lady Bridlington's ball, and her first evening at Almack's.

He sometimes shows some intelligence, such as realizing that Robert Beaumaris's adoption of a mongrel might be a prank on fashion-minded gentlemen like last time and that Arabella and Mr Anstey resemble each other.
