Swashtober 9 is Prudence Tremaine, from Georgette Heyer's absolutely wonderful 1928 romance novel THE MASQUERADERS. When Prudence and her brother have to hide out because of their father's involvement in the Jacobite Uprising, they drag up and go into London society, where Prudence keeps finding herself having to fight off folks with swords, while her brother spends his time flirting with everyone. The romantic lead is great, too - he's basically Mr. Darcy as played by Dave Bautista.
