Anjum Hasan looks at the phenomenon of “minor-character elaboration” – from Jean Rhys’s The Wide Sargasso Sea (the story of Jane Eyre‘s madwoman in the attic) to Margaret Atwood’s The Penelopiad (how Ulysses’s wife and queen passed the twenty years waiting for his return) and onward. (Hasan also includes Pride and Prejudice and Zombies, though we think that wasn’t the same thing.)
