One of Us is Lying: Chapter 9 Summary & Analysis

Sunday evening, Addy arrives at the small San Diego condo her sister Ashton shares with her husband. Ashton picked Addy up from the police station, and now makes some coffee for Addy. The two sit together on the balcony and talk; Ashton implores Addy to tell Jake the truth about her dalliance with TJ, as it’s bound to get out at some point, and for him to hear it from someone else would be terrible. Addy realizes that her sister is right—after texting Jake to ask if she can come over, she has Ashton drive her back towards Bayview so that she can come clean once and for all.

Jake’s mom lets Addy into the house and tells her that Jake is waiting for her downstairs in the basement. She finds Jake playing X-box, excited to hear about her afternoon. Addy, though, tells Jake that she has had a “scary day,” and that the detectives think Addy, Cooper, Nate, and Bronwyn murdered Simon. She tells him about the motive—the About That post detailing all four students’ secrets. Addy takes a second to muster up some courage, and then reveals to Jake that she slept with TJ over the summer. Jake is furious, and though Addy insists she loves him and simply made a mistake, Jake tells her that she has ruined everything between them. He orders Addy to get out of his house, and she stumbles crying down the driveway back into Ashton’s car.
