The diamond heart necklace is a symbol of Adam’s control over the women around him. The necklace first appears when Victoria’s diary indicates that Adam gave it to her early on in their relationship, immediately before asking her to move in with him. Victoria was astounded by the gift, writing, “I gasped when I saw a white gold chain with a diamond-studded heart pendant” (78). She took the necklace happily, wearing it with pride as a token of Adam’s love for her. However, Adam stopped treating Victoria with love and respect as their relationship progressed and his manipulation and control over her increased. When she put the necklace on later in their relationship, she even felt a “jab of sadness.” She kept the necklace, and she’s wearing it when Sylvia first meets her. Sylvia compliments her necklace, inadvertently complimenting Adam’s control over Sylvia’s life.
The necklace returns at the end of the novel, but this time, it has a new owner, as Sylvia notices at brunch: “My eyes go back to the necklace around Maggie’s neck. And then it hits me all of a sudden why the necklace looks so familiar” (371). Sylvia realizes, as she sees the necklace, that Adam has control over Maggie. Maggie lied to Sylvia at Adam’s behest, helped Adam hide Mack’s body, and even carried out an affair with Adam, before and after she knew that he was a murderer. As the necklace’s new owner, Maggie fills Victoria’s role under Adam’s thumb.
The dent in the wall in the Barnetts’ kitchen is emblematic of The Contrast Between Appearance and Reality. Sylvia notices the dent early in her employment, and Adam claims that it happened when a refrigerator was installed in the house. Sylvia does not think much about the dent until she reads in Victoria’s diary that Adam threw a plate at the wall in a fit of rage. The discrepancy in the stories remains unresolved as Sylvia attempts to understand the shifting landscapes of the relationships around her. She fixates on the dent, thinking, “I stare at the imperfection in the plaster. Was it caused by a refrigerator or a plate? I can’t tell. I’m not sure if I’ll ever know for sure what happened in this house” (267). Sylvia does not know who is manipulating her and who is telling the truth about the wall. Maggie then offers yet a third conflicting explanation, telling Sylvia that the dent was caused by Victoria throwing a microwave at Adam, further complicating Sylvia’s understanding of the Barnetts’ relationship. Instead of wondering if Victoria is being honest about Adam’s violent tendencies, Sylvia then wonders if Victoria is the violent one. Instead, Maggie manipulates her, using the dent in the wall to trick Sylvia, just as Adam manipulates Sylvia with his lie about the refrigerator.
Phones, TVs, and other devices with screens are a symbol of Victoria’s agency and independence—a lifeline to the outside world as Adam attempted to isolate her. Victoria had privacy and agency at the start of her relationship with Adam. However, as their relationship developed, Victoria began to lose her independence. The first clear evidence of the erosion of Victoria’s agency was the smashing of her phone after their engagement dinner. Adam flew into a jealous rage, alleging that Victoria cheated on him with Mack. When Victoria refused to give him the password to her phone, Adam threw the phone at her head. Though he didn’t hit her, her phone was destroyed. Victoria wrote in her diary, “The screen is so shattered, I can’t see anything. But what’s even more wrecked is my engagement” (194). The admission that she couldn’t see anything is a double entendre, as Adam’s manipulation left her unable to see his true character or the danger she was facing. Though this incident shook her badly, she took him back after he apologized, and their relationship continued. Adam later demanded the password to Victoria’s phone, demonstrating the further disintegration of her agency.
A screen appears again toward the end of the diary entries in the novel. After Adam murdered Mack, Victoria became catatonic with grief, watching TV constantly. In an attempt to break Victoria out of her anguish, Adam broke the TV, but Victoria did not break: “The screen smashed and the picture went black. He probably expected a reaction to that, but if he did, he was disappointed. I just kept on staring at the black screen” (322). Victoria refused to give Adam the satisfaction of hurting her any more than he already had, so she did not react, illustrating the brief return of her agency and foreshadowing her decision to attempt to leave.
