Antoinette Cosway renamed Bertha, then confined
Antoinette, a white Creole heiress in post-emancipation Jamaica, is married for her dowry of thirty thousand pounds to an unnamed Englishman, who under English law takes control of all her money. After Daniel Cosway sends him letters claiming her family carries hereditary madness, he begins calling her 'Bertha' despite her protests. He then removes her to a locked room in an English house, where she dreams of setting it on fire and walks out with a candle at the end.
