Irene was Slim’s wife. She doesn’t appear in person in the novel; she’s only mentioned in Slim’s stories and in a newspaper article by Caitlyn Spies. In Slim’s stories, his memories of Irene kept him sane and hopeful when he was imprisoned in Black Peter. According to Caitlyn’s article, Irene said she’d stay faithful to Slim when he was incarcerated a second time, but she wasn’t. Slim, however, insists to Eli that she was.
