Jackie is Adora’s oldest and ostensibly best friend in Wind Gap, a wealthy and pampered woman whose alcoholism and forays into plastic surgery are open secrets in town. Jackie and Adora have been feuding when Camille first arrives in Wind Gap, though the sweet—and often inebriated—Jackie treats Camille warmly, even inviting her to come to lunch and gossip with her and her friends. When Camille grows suspicious of her mother’s involvement in the deaths of Ann and Natalie, whom she was tutoring—and begins to believe that her mother intentionally killed her perpetually sick younger sister, Marian, years ago—she seeks out Jackie, who more or less confirms the truth. Adora did kill Marian, and has gotten away with it for all these years—“A beautiful girl can get away with anything,” Jackie says, “if she plays nice.”
