Full Summary
The Murders and the Family
The novel opens with the discovery of Fred and Sheila Merton's bodies in their Brecken Hill mansion on Easter Monday. Sheila lies strangled in the living room, and Fred has been stabbed repeatedly with his throat slit in the kitchen. The house has been ransacked, suggesting a robbery, but the brutality points to something more personal. The Mertons' three adult children—Dan, Catherine, and Jenna—each become suspects as Detectives Reyes and Barr investigate.
The Easter dinner the previous day reveals a deeply dysfunctional family. Fred, a wealthy robotics businessman, humiliates his children at the table: he announces plans to sell the family home, criticizes Dan for losing the business, dismisses Jenna's art, and taunts Catherine about not having children. Dan, unemployed and financially desperate since his father sold Merton Robotics out from under him, had hoped to ask for money but is publicly shamed instead. Catherine, the favored eldest daughter and a dermatologist, covets the family home. Jenna, a rebellious sculptor, brings her new boyfriend Jake and openly despises her father.
The Investigation and Family Lies
As the investigation unfolds, each sibling conceals crucial information. Catherine secretly visited her parents' house the night of the murders, discovered their bodies, and fled without calling police—she suspected Dan and wanted to protect him. Dan went for a late-night drive, lying about his whereabouts. Jenna asked Jake to provide a false alibi. The housekeeper Irena Dabrowski, who raised the children, cleaned the murder weapon and returned it to the knife block, hoping to protect the family.
The detectives learn that Fred had planned to change his will to favor his sister Audrey Stancik, giving her half the estate. Audrey, who expected a windfall, is furious that Fred died before making the change. She suspects one of the children and begins her own investigation, revealing a childhood secret: when she was eleven, her brother Fred murdered their abusive father and staged it as a suicide, and she helped cover it up.
Rose Cutter and the Hidden Heir
The will reading reveals a fourth child: Rose Cutter, Fred's illegitimate daughter, inherits an equal share. Rose, a lawyer and Catherine's longtime friend, had also defrauded Dan of half a million dollars in a fake mortgage scheme. She knew about her inheritance months before the murders through a breach of confidentiality by a law firm associate.
The Poisoning and the Arrest
Audrey is poisoned with antifreeze in her iced tea but survives. Suspicion shifts among the family members. The detectives arrest Irena after a witness places her car near the crime scene, but phone records prove she was home that night. The car had been taken by someone else—someone who knew where Irena kept her spare keys.
Jenna's Confession
The truth emerges in a flashback: Jenna committed the murders. After dropping Jake at the train station, she took disposable coveralls from Dan's garage, retrieved Irena's spare keys, and drove Irena's car to her parents' house. Wearing the coveralls and carrying an electrical cord, she strangled her mother at the door, then killed her father with a carving knife when he came downstairs. She staged the robbery, took jewelry and valuables, and buried the evidence under concrete at a rural property. She also poisoned Audrey's iced tea.
The Epilogue
A year later, Catherine, Ted, and their new baby live in the Merton family home. Audrey remains convinced of Jenna's guilt, having traced her route and discovered the freshly poured concrete foundation, but police cannot dig without cause. The novel ends with Audrey receiving her inheritance and calling the realtor about the property where the evidence lies buried.
