⚠️ Spoiler Alert
This chapter summary and analysis contains plot details for Chapter 23 (numbered Chapter 24 in some editions) of She Didn’t See It Coming by Shari Lapena. If you haven't read this chapter, proceed with caution.
Summary
The chapter opens in the Frost family home after Bryden’s funeral. Lizzie’s mother, visibly aged and exhausted, signals Lizzie to follow her to the kitchen. Lizzie pretends to refill her coffee and joins her mother, who whispers a startling question: “What if Sam did it?” Her mother’s face is strained, her eyes full of painful possibility. Lizzie is not completely surprised by the question but is unprepared for the shift in family dynamics it represents. When Lizzie hesitates, her mother interprets this as agreement and accuses her of thinking Sam is guilty. Lizzie insists she doesn’t know and cannot believe Sam killed his wife. Her mother points out Sam’s lack of an alibi and wonders if Bryden was hiding secrets. Overcome with grief, Lizzie’s mother begins to sob, blaming herself for not being there for her daughter. Paige enters the kitchen unnoticed and overhears part of the conversation; she comforts Lizzie’s mother firmly, telling her it is not her fault.
The scene shifts to the police incident room. Detective Jayne stands before a whiteboard now featuring photos of Bryden Frost, Sam Frost, and Derek Gardner. She briefs her team on the case. Derek Gardner is a smooth suspect with a sharp attorney; he claims he was home alone working at the time of the murder. Jayne orders a thorough search of CCTV footage from the area around the condo building and beyond, covering all the way back to January 26, when Bryden and Derek met. She also asks for background checks on Gardner’s business and marriage. The team confirms that Sam Frost also has a weak alibi. A food truck owner, Gino Morelli, confirmed Sam bought lunch at 12:15, but there is no CCTV coverage for Sam’s car after that. Jayne outlines the theory: Sam could have driven home (a seven-minute trip), had Bryden buzz him in (leaving no record), killed her, undressed her, placed her in a suitcase, and taken it to the storage locker. He would have had to dispose of her clothes, possibly on his way back to work. The team has found no cameras on that route. Jayne speculates that Sam may have moved the body to prevent his young daughter from seeing it when he picked her up from day care. Kilgour adds that Derek Gardner might have known about the broken parking garage cameras and could have been invited over by Bryden; he might have killed her on a sudden impulse if she threatened to expose the affair. Jayne concludes that neither suspect has a strong alibi and that the case currently lacks physical evidence. She and Kilgour then leave for the coroner’s office to receive the autopsy results.

Themes, Symbols, or Motifs Actually Evidenced Here
- Suspicion within the family: The chapter marks the first open doubt about Sam’s innocence from within the family. This fracture represents the corrosive effect of the crime on close relationships.
- The unreliability of alibis: Both Sam and Derek claim to have been alone during the murder window, but neither alibi can be independently verified. This highlights the challenge of proving a case without witnesses or digital evidence.
- The suitcase as a symbol: Although not explicitly described, the suitcase used to hide Bryden’s body symbolizes the dehumanization and concealment of the victim. The police refer to it only as a practical object, emphasizing the clinical nature of their work.
- The search for truth versus the need for closure: Jayne’s team works to uncover facts while the family struggles with emotional turmoil and the desire for answers, two parallel processes that may or may not converge.
Why This Chapter Matters
This chapter is pivotal because it introduces the possibility that Sam Frost, the husband and a family member, may be the killer. The private conversation between Lizzie and her mother shifts the emotional landscape of the story, placing the family under internal suspicion. Simultaneously, the police investigation gains momentum with a clearer timeline and a second strong suspect, Derek Gardner. The chapter sets up a race between the two theories—and suggests that the truth may be hidden not only in physical evidence but also in the secrets kept by those closest to Bryden. By ending with Jayne heading to the coroner, the chapter raises the stakes for the next stage of the investigation.
Study Questions and Answers
1. Why does Lizzie’s mother begin to suspect Sam, and what does this reveal about her state of mind?
Lizzie’s mother suspects Sam because he lacks a solid alibi for the time of the murder. She also questions whether they truly know him. This reveals her grief-stricken and paranoid mindset; she is searching for someone to blame and feels an overwhelming guilt for not protecting Bryden.
2. How does Detective Jayne’s theory of Sam’s actions account for the gap in his timeline?
Jayne hypothesizes that Sam picked up lunch at 12:15, drove home to the condo, had Bryden buzz him in (avoiding a record), killed her and placed her in a suitcase, then stored the body and disposed of her clothes before returning to work around 2:00 PM. The gap between 12:15 and 2:00 PM gives him approximately 1 hour and 45 minutes to commit the murder and hide evidence.
3. What makes the case difficult for the police so far, according to the chapter?
The case is difficult because there is no physical evidence linking either suspect to the crime. Both Sam and Derek have weak alibis, but no CCTV footage confirms their movements during the critical period. The murder weapon is missing, and Bryden’s clothes have not been found. The broken parking garage cameras also leave a gap in surveillance.
