Paige Mason: The Best Friend Who Became a Killer

Overview

Paige Mason is the book’s central antagonist, concealed beneath a mask of loyalty. As Bryden Frost’s college-era best friend and Clara’s godmother, she insinuates herself into the family’s life while secretly nurturing an obsessive love for Sam Frost. Her quiet desperation and jealousy drive her to murder Bryden in a premeditated act, then orchestrate a frame job that nearly derails the investigation. Paige exemplifies how a seemingly devoted friend can harbour deadly secrets, and her arc traces the collapse of a carefully constructed persona.

Plot Role

Paige’s plot function is twofold: she is the catalyst of the central crime and the primary red herring before her guilt is exposed. From Chapter 2 onward, she plays the grieving confidante, feeding false information about Bryden’s alleged affair with Derek Gardner to deflect suspicion. Her false alibi—claiming she was home sick on the day of the murder—unravels when a witness places her in the elevator with the suitcase containing Bryden’s body, and her ringtone, “Bitter Sweet Symphony,” seals the identification (Chapter 60). She initially accuses Sam of the murder in a desperate attempt to save herself, but his verified alibi forces her to stand alone as the killer. Her confession in Chapter 63, culminating in a flashback of the suffocation, provides the definitive resolution.

Motivations and Traits Shown Through Actions

Paige’s primary motivation is unrequited love for Sam, twisted into a belief that removing Bryden would let her take over her friend’s life. She confides to herself that she “could love Clara almost as much as her real mother” and dreams of a home with Sam, even of giving Clara a sibling using the baby supplies Bryden had stored away (evidence, Chapter 54). This delusion reveals a profound sense of entitlement and a capacity for rationalising violence.

Her traits emerge through patterns of manipulation and calculation. She lies effortlessly to detectives, feigns tearful distress during interviews, and concocts the affair story to “deflect” (Chapter 26). She is patient and observant—she knew Bryden would be home alone, knew the suitcase was in the closet, and wore gloves and a nondescript hood to avoid detection. She even vacuumed the apartment to eliminate trace evidence. Yet her plan cracks under the weight of her own fabricated lies and Sam’s hidden drug addiction, which she never anticipated.

Chronological Arc

Before the murder: Paige is described as Bryden’s closest friend, present for years. She helps Bryden move baby items to the storage locker—the same locker where she later hides the body (Chapter 54). Her resentment simmers below surface-level friendliness.
Day of the murder (flashback, Chapter 63): Paige buzzes Bryden’s intercom, claiming she needs to talk. Once inside, she attacks from behind with a plastic bag, suffocating Bryden while Bryden’s last thoughts are of Clara. Paige stuffs the body into a suitcase, wheels it to the elevator, and is seen by a witness.
During the investigation: She attends the condo grieving, deflects questions, and plants the false affair story with police and with Sam. She begins a brief sexual relationship with Sam after Bryden’s death, believing she is building a new life with him.
Crisis and collapse: Detectives confront her with the elevator witness and the ringtone. She implicates Sam. When Sam provides a solid alibi (his oxycodone dealer), she erupts in rage and is charged alone (Chapter 64). Her confession reveals the premeditation and her bitter realisation that Sam never truly loved her.

Relationships

Bryden Frost: Initially genuine friendship, curdled by envy and possessiveness. Paige knows intimate details of Bryden’s life—her work schedule, her storage locker, her struggle to conceive—and weaponises that knowledge.
Sam Frost: A one-sided, obsessive love. Paige believes Sam can grow to love her, but he takes her for granted and calls her “crazy” to the police. Their brief affair after Bryden’s death is transactional, not romantic.
Clara: Paige sees herself as a surrogate mother, a delusion that rationalises the murder as “some good” coming from tragedy.
The Detectives: Jayne Salter and Paul Kilgour read her body language, catch inconsistencies, and methodically dismantle her lies. Her final outburst shows her contempt for their competence.

Key Decisions and Consequences

Decision	Consequence
Murdering Bryden with a plastic bag	Ends Bryden’s life and traumatises Clara; sets off a police investigation that eventually closes in on Paige.
Framing Derek Gardner as Bryden’s lover	Temporarily distracts the police but later crumbles when Paige admits it was fabricated; it also endangers Derek and Alice Gardner and reopens a hit-and-run case.
Confessing that Sam killed Bryden	A desperate gambit that backfires when Sam’s drug alibi is verified; it removes any possibility of a plea deal.
Wearing gloves and vacuuming	Eliminates forensic evidence from the apartment, but the elevator witness and phone call provide circumstantial proof that withstands her denials.

Theme and Symbol Connections

This analysis feeds into the broader themes of deception and hidden lives and betrayal and loyalty. Paige’s double life—the loyal godmother versus the calculating killer—illustrates how easily facades can hide darkness. Her obsession with true crime, hinted at by the novel’s setting (Lizzie’s online sleuthing), aligns with the theme of obsession with true crime. The plastic bag she uses is a stark domestic symbol: something as ordinary as a kitchen bag becomes a weapon, underscoring the theme of domestic violence and marital secrets. The justice and investigation theme is advanced by Paige’s ultimate failure to escape justice, despite her careful planning.

Book-Specific Questions and Answers
