premise: Laura Warholic; or, The Sexual Intellectual is a 2007 novel by Alexander Theroux. The plot concerns the relationship between Eugene Eyestones, the writer of an advice column called "The Sexual Intellectual", and his editor's ex-wife, Laura Warholic, whom Eyestones pities more than likes. This basic story provides the jumping off point for Theroux's satire of American culture.
hypothesis: Laura Warholic; or, The Sexual Intellectual starts with Eugene and Laura already being divorced.
reason: There's nothing in the statement about when they are divorced. The only information is that at some point in the book Laura becomes Eugene's ex-wife.
