To explain Bill Hardy’s model’s performance, we suggest that Bill’s pages have a textual characteristic that makes them easily identifiable. Bill’s model erroneously labels these pages, categorizing non-Bill pages written in the present tense as belonging to Bill. For instance, while a good model would identify the existence of spoonerism in Jasmine’s monologue (e.g., “Useful, courteous little chip of a bat”, page 27), a great model would be able to identify when a different narrator refers to Jasmine’s spoonerisms: “He said he’d put that right, but he couldn’t find the silly old jossers, as Jasmine might so easily have called them” (page 99).
