Most of the characters and many events in the novel demonstrate the misleading nature of appearances. Sometimes characters intentionally try to deceive, while others simply misinterpret what they observe; in both cases, the end result is a description of events that deliberately deviates from reality in order to increase the overall suspense of the plot as the author plays with a variety of conventional “whodunit” tropes. Several of Eleanor’s guests, and even Eleanor herself, illustrate just how deceptive appearances can be, for Rupert, Freddy, Cece, and Inspector Dobson all pretend to care about Eleanor even as they try to exploit or control her. For example, Maggie and Ethan overhear Rupert chastising Dr. Charles for dithering over their “plan” to falsely contend that Eleanor is “no longer of sound mind” and needs someone “to take over her affairs” (159). In addition to hiding the true reason for the doctor’s presence at the gathering, Rupert has been quietly diverting millions of dollars from Eleanor’s royalty checks, and his plan to have Eleanor declared unfit reveals his wish to access the rest of her fortune as well.
In addition to facing threats from her actual relatives, Eleanor must also contend with fake ones, as when Freddy falsifies Cece’s DNA test so that she can pretend to be Eleanor’s long-lost, doting niece and gain a place in Eleanor’s will. Finally, Eleanor must determine who her true friends are; as the novel’s climax reveals, Dobson has pretended to be Eleanor’s friend—and an upstanding police officer—for the last 40 years. Maggie accuses him of lying about the woman he left for dead and of trying to murder Eleanor to keep her quiet about it. Maggie says that Eleanor’s last novel is about the inspector’s intended victim. She tells him, “You know the case you came to Eleanor asking for help with forty years ago? The crime you thought you’d gotten away with? Well, Eleanor outsmarted you then when she got your victim out of the country. And she’s outsmarted you now” (271). Not only is Dobson a would-be murderer, but he also engaged in a decades-long deception, undetected by everyone except Eleanor.
Although much of the novel focuses on the various deceptions of the wrongdoers involved, it is important to note that both Eleanor and Ethan use deception for their own purposes. However, unlike the guilty guests at the Christmas party, they lack malicious intent, and many of their ploys are meant as forms of self-protection. For example, Eleanor is well aware that the people in her life equate her physical frailty with mental incapacity, and when she is faced with Rupert and Cece’s facile attempts to fool her into believing their stories, she must take elaborate measures to protect herself and her assets from their machinations. In fact, the entire premise of the novel is predicated upon Eleanor’s ability to engage in elaborate deceptions that are paradoxically designed to reveal broader truths.
Ethan, on the other hand, projects a somewhat curated public persona because he has recently survived a number of hardships and has consciously remade himself, overcoming injury and addiction to become the suavely confident “Ethan, the Guy in the Leather Jacket” (46). In the opening chapters, Maggie routinely refers to Ethan’s “mask,” his “persona,” and his “façade,” using a tone that illustrates her deep suspicion over his seemingly phony demeanor. However, in this case, her negative view of him dissolves when she gets to know him and realizes that “Ethan […] was who he needed to be to survive: someone charming and easy and cool. Someone who makes friends and keeps the peace. The life of the party. The guy who gets invited back” (204). Unlike Rupert or Dobson, Ethan hasn’t adopted his persona to harm or exploit anyone; instead, he is trying to protect himself from pain and rejection. His harmless social tactics contrast with other characters, and while Maggie shrewdly exposes the subterfuge of the other guests, she comes to understand that she has unfairly judged Ethan.
Throughout the novel, much of Maggie’s inner development comes from her increasing willingness to extend trust and engage in teamwork with the charismatic Ethan. Haunted by the toxic dynamics of her failed marriage to the gaslighting, unfaithful Colin, she is still recovering from a relationship that was essentially a twisted game: one that warped her sense of self and deeply impacted her ability to take others at face value. When Colin betrayed her by sleeping with her best friend, Maggie grew distrustful of men’s motives, and now, her wariness extends to Ethan. However, as the two spend more time together, she realizes that Ethan fooled her with his suave authorial persona; in reality, his unwavering support whenever she takes the lead in their investigation shows her what a healthy relationship should feel like, whether it’s romantic, platonic, professional, or a mix of all three. As Maggie slowly sets her suspicions aside, she learns that embracing teamwork is a valuable strategy for solving problems and for gaining a deeper sense of safety and well-being.
The understanding between Maggie and Ethan grows quickly as they strive to deal with the serious disruptions that begin almost as soon as they arrive in Eleanor’s house. When Cece cannot find Eleanor on the morning after the guests’ arrival, the group descends into bickering about what to do next, and only at this point does Maggie realize that Ethan “didn’t feel like a stranger anymore,” and she marvels at the fact that “[t]hey were the only silent people in the space but a whole conversation seemed to be taking place between them” (75). With their silent exchanges and frequent brainstorming sessions, it becomes clear that Maggie and Ethan share values, skills, and interests, and their multiple points of connection allow them to develop a mutual system of awareness and support.
This dynamic becomes increasingly prominent as the story develops, showcasing Maggie’s emotional evolution. When Maggie begins to solve Eleanor’s clues, she initially does so alone because of her history of being betrayed, and she explicitly tells herself that she “didn’t need Ethan. She just needed a plan and a strategy and about five hundred Post-it notes” (91). However, with the attack in the maze, she realizes that her stubborn individualism is not enough to help her solve the mystery and preserve her own life. Ethan not only protects her body with his own, but he also defends her expertise when others doubt it, and Maggie is “grateful for the sure, steady weight of him” (124) beside her. She enjoys the certainty that comes with the knowledge that Ethan wants to protect her from harm and help her succeed.
This enjoyment leads to a deeper form of emotional intimacy that only adds to their cohesion as a team. When she realizes that someone has made four attempts on Eleanor’s life, “Maggie wasn’t afraid, and she didn’t let herself think about how—without the man beside her—she would have been terrified” (184). Moreover, Ethan also sees Maggie as “ someone who trusted him […]. Wanted him. Like they were a team” (278), and rather than finding such intimacy “terrifying,” he embraces it in return. Thus, their teamwork closely aligns with their growing romance and eliminates their fear, making them both feel valued and important. With these emotional needs met, they are better able to focus on the problems in front of them.
Gaslighting is a form of emotional abuse and manipulation in which the abuser deliberately denies their target’s reality, making them doubt their own memory, experiences, and judgment. The concept and term originated with the 1944 movie, Gaslight, in which a husband makes subtle modifications to his wife’s environment—like dimming their gas lights—then claims that nothing has changed. He does this to make her feel as though she is losing her mental stability. By convincing her that her perception of the world cannot be trusted, he asserts an unhealthy degree of control over her life. Likewise, Maggie’s ex-husband Colin habitually gaslit her during their marriage in order to deflect her suspicions about his infidelity. His tactics made her feel untrustworthy, paranoid, and incompetent; as her insecurities throughout the novel show, the effects of Colin’s abuse continue to plague Maggie even a year after the revelation of his betrayal. Only with Ethan’s support and her own successful investigation into Eleanor’s disappearance does she finally regain confidence in her own perceptions and judgment.
However, consciously acknowledging the toxicity of Colin’s tactics does not prevent them from causing emotional damage, and Maggie continues internalizing these old criticisms in new ways. A prime example occurs when Maggie thinks of herself as “silly” or “foolish” when she considers moving her dresser to block her door after Eleanor disappears. She often thinks accuses herself of being “paranoid” because Colin always made her feel “a little bit crazy” (171) by claiming that she was overreacting, misinterpreting, or being unreasonable. Even now, Maggie thinks that if she hadn’t walked in on Colin and Emily having sex, she “might still be telling herself that it was all in her head” (171). The shadow of this power differential continues to disturb her, as when she speculates that if she had lived a century ago, Colin could have used his false claims to rob her of her liberty and have her committed to a mental health institution. By inserting such contemplations into the narrative, the author stresses the deeply damaging nature of gaslighting and highlights its historical patterns, drawing attention to the harmful patriarchal patterns that still exist in society.
Gaslighting is widely acknowledged as an effective strategy because the targets come to see themselves as flawed, prone to error, and even damaged. Thanks to Colin’s gaslighting, Maggie believes that “even the people who were legally obligated to love [her] shrugged and said maybe not. She […] was alone and afraid and nothing. She was nothing” (99). The bleak, defeated tone of this passage emphasizes how worthless Colin’s abuse makes her feel, even after she learns the extent to which he was willing to deceive her. Even more illustrative are the reactions of those like Eleanor and Ethan, who care about Maggie, every time that Maggie “pull[s] herself back, taking up less space and making herself a smaller target” (160). Even when Maggie sleeps, Ethan notices that she curls up in a ball, as if “she wanted to take up as little space as possible, like she wasn’t even entitled to half of her own bed” (142). These subtler behavioral patterns emphasize the visceral level of damage that Colin’s manipulations have caused, for now, even a year after her divorce, Maggie continues to carry her insecurities into other relationship dynamics. Her trauma-based quirks show that targets of emotional abuse often believe the messages they get from their abuser and have difficulty in shedding these internalized attitudes even after the abuse has ended.
Only after Maggie and Ethan uncover the truth about Eleanor and her 100th novel does Maggie begin to see parallels between Colin’s abuse and the way in which the guests have tried to gaslight Eleanor. When she observes these toxic patterns aimed at the smartest, cleverest, and most thorough thinker she knows, she realizes that the same thing has been done to her. When she addresses the household at the end of the novel, she suddenly realizes that she “wasn’t talking about Eleanor anymore,” and she says, “You know, if mankind has one universal superpower, it’s gaslighting women into thinking they’re the problem” (262). Without the experience of witnessing another woman becoming the target of gaslighting, Maggie might never have been able to move past the trauma of Colin’s similar abuse.
