Full Summary

Prologue – The Accusation

The story begins twenty‑four hours before Abby expects to be arrested for first‑degree murder. Her lawyer urges her to accept a plea bargain, but Abby insists she is innocent. Her husband Sam sits silently, making her feel utterly alone. Abby begins to doubt her own memory, wondering if she could have committed the crime.

The Surrogacy Begins

One year earlier, Abby is a successful advertising executive. She hosts a baby shower at work, but the celebration is ruined when Sam reveals that their surrogate Janelle has changed her mind and will keep the baby. Devastated, Abby considers giving up on having a child.

Her assistant Monica, a bright young woman, offers to become a surrogate in exchange for tuition for her master’s degree. Abby is shocked but intrigued. Sam initially refuses, listing practical concerns, but Abby’s emotional plea convinces him to meet Monica. After a formal interview, Sam grudgingly agrees. The contract is signed: Monica will carry the baby using her own egg and Sam’s sperm.

The Pregnancy and Growing Tension

On the first insemination, Monica becomes pregnant. Abby is overjoyed, but Sam’s reaction is tepid. Small red flags appear: Monica claims to be from Indiana yet is a passionate Red Sox fan. At Abby and Sam’s anniversary dinner, they encounter Monica, who enthusiastically discusses violent Tarantino movies—a contradiction to a previous remark that she found such films “so violent.”

Monica begins to insert herself into the couple’s life. She texts Sam, records the baby’s heartbeat for him, and invites him to her ultrasound without Abby. Sam attends and does not correct the doctor who assumes he is Monica’s husband. Abby’s friend Shelley warns that Monica may be scheming, but Abby dismisses the warnings.

The Frame‑Up

Abby begins making mistakes at work: missing meetings, misplacing files, and accidentally insulting her boss Denise via email. Her job is threatened, but Monica defends her. Meanwhile, Abby’s former assistant Gertie visits and jokes that her stair‑fall “felt like a push”—a fall that happened right before Monica replaced her.

Abby starts taking sleeping pills but stops them before a scheduled drug screen. She fails the test: it is positive for methamphetamine. She is fired. Sam finds a bag of white crystals in her drawer, which he flushes, insisting he believes her but clearly doubting her sanity.

The Murder

Denise Holt calls Abby, admitting she may have been wrong about the drug test. She caught Monica going through her desk and found Adderall in Monica’s cubicle. Denise asks Abby to meet her at the office at 8 PM. When Abby arrives, she finds Denise dead behind her desk. A detective shows Abby a blood‑soaked letter opener engraved with her name. Abby is questioned but not arrested. She realizes she has been framed for murder.

Uncovering the Truth

Abby’s lawyer warns she could face fifteen years in prison. While riding with Sam, Abby spots Chelsea—the girl who pretended to be Monica’s roommate—and forces a confession: Monica paid her two hundred dollars to lie. Abby tracks down Monica’s ex‑roommates, who describe paranoid behavior, a sharpened stake under her bed, and a past suspicious death. She then visits Monica’s mother, Louise Johnson, who reveals that Monica has borderline personality disorder, a genius IQ, and was a suspect in a high‑school friend’s drowning. Most damningly, Monica had an affair with a married math professor named Sam—Abby’s husband—three years ago.

Abby confronts Sam, who denies an affair but the evidence mounts. She realizes the entire surrogacy plot was orchestrated to frame her and allow Sam and Monica to be together.

The Climax

Gertie arrives at Abby’s apartment, makes breakfast, and drugs Abby’s orange juice. Monica appears, revealing that Gertie is her mother. They have conspired all along. Monica shows a forged suicide confession, pulls a gun, and tapes Abby’s limbs. Sam unexpectedly arrives. Monica hides Abby, but Sam notices Abby’s belongings and finds her tied up. As Sam tries to rescue Abby, Monica holds him at gunpoint. During the struggle, Monica shoots Sam in the arm. Gertie emerges from the closet, and Abby tackles her; Monica accidentally shoots her mother dead. Monica then turns the gun on Abby and Sam, but Sam shields Abby. A final gunshot is heard—Monica shoots herself.

The Aftermath

Abby wakes in the hospital. Sam survived; Monica is in a permanent vegetative state. The baby, David, is healthy. Police evidence clears Abby of Denise’s murder. Abby and Sam raise David together. In the epilogue, set a year later, Monica’s stepmother visits and gives Abby Monica’s childhood blanket. Abby plans to throw it away, but baby David becomes inconsolable, begging for the blanket. He buries his face in the lingering scent of Monica’s perfume. The story ends on this unsettling note, suggesting Monica’s legacy can never be erased.
