Dr. Roy Davies serves as the novel’s primary antagonist, a man whose esteemed public persona conceals a private reality of jealousy and psychological abuse. As a renowned psychologist and bestselling author, he exemplifies Professional Prestige as a Shield for Coercive Control, leveraging his professional credibility to manipulate and control those around him, particularly his wives. Roy projects an image of a charming, caring, and tragically widowed husband, winning the sympathy of his friends who perceive him as a “saint.” 

Roy’s ostentatious public mourning for his first wife, Deborah, belies the infidelity and systematic psychological torture he subjected her to while alive. His character is a study in hypocrisy as he builds a career on helping others heal while privately destroying the women he claims to love. Roy’s possessiveness manifests as extreme coercive control. Convinced of Deborah’s infidelity, he locks her away, framing his abuse as a legitimate therapeutic intervention for a fabricated mental illness. Diagnosing her with “factitious disorder” (174), he uses his expertise to gaslight Deborah and his entire social circle, who unquestioningly accept his narrative. 

In the early days of their relationship, Roy calls Jodie his “beautiful porcelain doll” (98). While intended as a compliment, the description expresses his desire for a perfect woman who lacks all agency. His second marriage to Jodie portrays him as a static character, incapable of moral growth, as he soon replicates the behavior he displayed with Deborah by unjustly accusing her of infidelity while planning to rekindle his affair with Veronica. When Jodie’s suspicions come too close to the truth, he pathologizes her valid concerns, suggesting she see a psychologist. 

Despite his intelligence and manipulative skill, Roy is ultimately outmaneuvered by Jodie’s superior cunning and ruthlessness. His affair with Veronica provides a supposed motive for Deborah’s murder, and his lack of a credible alibi makes him an easy target to frame. While he is not Deborah’s killer, his abuse created the conditions for her murder and made him a plausible suspect. His imprisonment for crimes he did not commit is presented as a fitting, if not entirely just, consequence for his cruelty.

Marie is the secondary antagonist, a character whose true nature as a calculating, obsessive killer is gradually revealed. Initially presented as a resentful and passive-aggressive housekeeper, she mirrors Jodie’s ability to perform a subservient role while harboring secret, violent intentions. Marie’s motivations are rooted in a delusional obsession with her employer, Roy Davies. Her belief that she is the only one who truly loves him and is entitled to be his wife leads her to systematically eliminate any rival. Her resentment of Jodie is palpable from the beginning, but is initially presented as fierce loyalty to the deceased Deborah. Jodie’s reflection that Marie “reminds me of this movie I saw once, called Rebecca, with the crazy housekeeper who goes mad with grief when Rebecca dies” (49) draws attention to her character’s superficial resemblance to Daphne du Maurier’s character Mrs. Danvers. By deliberately evoking this Gothic trope, Marie constructs a misdirection that conceals her role as Deborah’s killer. 

Marie embodies an insidious form of evil that thrives under the cover of domestic service. Her past as a cosmetic nurse provides her with the tools for her sinister plot. Fired for stealing drugs, she possesses the medical knowledge to slowly disfigure both Deborah and Jodie by secretly injecting them with fillers and other agents while they sleep, a uniquely cruel form of abuse that targets the beauty she envies. Duplicity is her defining characteristic, underscored by Jodie’s half-admiring declaration, “that woman is such an actress” (183). She plays the part of the devoted employee to Roy while actively torturing his wives. She also pretends to be an ally against Roy to both Deborah and Jodie. Marie’s final confrontation with Jodie reveals the full extent of her dangerous delusion, as she dons Deborah’s wedding dress and speaks of her entitlement to Roy’s affection. However, she underestimates Jodie, unaware that she is equally capable of manipulation and violence. This fatal error in judgment leads to her violent death.

Deborah Adams, known to her sister as Deb, serves as the novel’s central catalyst and tragic victim. Though deceased before the main narrative begins, her presence permeates the story through photographs, memories, and the ongoing investigation into her death. She is characterized as a kind, beautiful, and vivid woman through Jodie’s loving recollections and others’ accounts. 

Jodie’s narrative presents Deborah as a foil to her dark side. Observing that her sister “lived in a world of silver linings and green shoots” (316), she contrasts Deborah’s determination to see the best in people with her own cynicism and rage. Jodie’s experience of hearing Deborah’s voice urging her not to kill Detective Bates suggests that Deborah served as her conscience while alive, moderating her violent impulses. Deborah’s defining trait of optimism leads Jodie to disbelief that she died by suicide. She asserts, “honestly, if you’d met Deb, you would have known that plan was never going to work. She was the most hopeful person you’d ever met” (316). Her unwavering love and support for Jodie during their traumatic childhood were the only genuine source of affection in the protagonist’s life. 

Deborah’s murder provides the moral and emotional justification for Jodie’s quest for vengeance. The idealized portrait of her in the living room is a constant reminder of the injustice Jodie seeks to correct. Her final, hidden letter reveals her strength and determination even while imprisoned, presenting her as a strong, resilient woman whose trust was fatally betrayed.

Veronica Greenwood, who introduces herself to Jodie as Erin, is a minor antagonist and unwitting victim in the narrative. As Roy’s mistress, she is a rival to both Deborah and Jodie. Her decision to adopt the persona of Erin to investigate Jodie reveals a layer of cunning and curiosity. She manipulates their first encounter at the gas station, feigning a chance meeting to gather information about the woman who supplanted her in Roy’s life. Although this act of deception places her in direct opposition to Jodie, she is ultimately no match for Jodie’s far deeper capacity for manipulation and violence. Veronica’s accidental death during their confrontation demonstrates The Corrosive Nature of Vengeance, as Jodie’s justified investigation transforms unequivocally into a violent, single-minded quest for revenge. Her death provides Jodie with the perfect opportunity to frame Roy, turning Veronica into a piece of collateral damage in Jodie’s destructive path to revenge.

The “Harpies,” a collective term for Roy’s friends Meredith, Eileen, and Barb, embody the superficiality and hypocrisy of their wealthy social circle. They engage in cruel gossip, performatively mourn Deborah, and are easily manipulated by Roy’s professional authority. Meredith, in particular, is cruel and class-conscious, using Jodie for her cooking skills while simultaneously looking down on her. She illustrates the entitled perspective “that everyone else is there to serve them” (125). The group functions as a chorus, reflecting the community’s shallow values and their failure to see the truth beneath the polished surface.
