A Passage to India
by E.M. Forster
Miss Derek, a friend and frequent guest of the McBrydes, works for one of the Hindu princes in a nearby princely state. She's the party girl of the set – single and always game for a good time. Her habit of absconding with her employer's car comes in handy when she rescues Adela after her "rape" at the Marabar Hills. We later find out that the girl's been having an affair with Mr. McBryde.
