At the police station, the IT team tells Jayne they have found the Facebook group discussing Bryden’s case. Jayne reviews the posts. She reads the post in which “Emma Porter” claims it was her idea for the police to use a cadaver dog to find Bryden’s body. Jayne remembers that Lizzie said the same thing to Jayne in an interview, and when she deduces that Emma Porter is Lizzie’s pseudonym, she wonders if Lizzie murdered her sister.
Jayne interviews Lizzie at the police station. The detective states that Lizzie was not as close with Bryden as she claimed to be, given that Lizzie did not know about Bryden’s affair. When Jayne asks Lizzie the reason for her online activities as Emma Porter, Lizzie says she was trying to help the investigation and did not tell her parents about it because she felt they would not approve.
Lizzie explains that her parents do not approve of her interest in true crime because they think it is “disgusting, unhealthy.” Jayne posits that Lizzie likes posting in the group because she “enjoy[s] being in the know” (294). Lizzie denies this. Jayne says Lizzie’s posts suggest she knows a lot of details about how Bryden died, and she asks if Lizzie was jealous of Bryden.
Lizzie returns home and tells Donna that the police suspect her of murdering Bryden because of her Facebook posts. Her parents demand to see the posts.
Derek returns home late and tells Alice that he knows about her past. Alice confesses that she killed a man when she was a teenager because he assaulted her. She was never charged because the police “realized that it was so clearly self-defense” (299). Derek then confesses to her that he has been doing illegal work for some clients to make good money. She understands this because she also wants to be rich. That night, Alice thinks about her childhood friend, Susan Cleeve. Susan knows something that could reveal that the murder Alice committed as a teenager was not self-defense.
When Alice was a teenager, she had an affair with an older, married man. At first, she found it exciting. When she became bored and broke it off with him, he continued to pursue her, so she told him to meet her in a ravine at night, then she murdered him with a rock. She told the police that she killed him in self-defense, and only her friend Susan had known that Alice had been dating an older man. Now, Alice hopes that Jayne arrests someone for Bryden’s murder soon so that they will stop investigating her past.
Jayne returns home and is troubled to see that things in her apartment have been moved.
The next day, Jayne goes to work, feeling tired after a sleepless night wondering who broke into her apartment. She wonders if it was Alice. She and Detective Kilgour review their evidence in the case and decide to check Lizzie’s alibi.
Paige drives Clara to day care, feeling frustrated that Sam did not want to spend time with her. She reflects that “what she knows could hurt him” (307).
Alice looks up Jayne’s boyfriend, Michael Fraser, online. He is a professor in the Psychology Department of the university, so she decides to attend his lecture.
Tracy Kemp meets with Kayly Medoff (the woman whom Henry was accused of kidnapping and raping). Kayly does not recognize her as Henry’s wife. Tracy tells Kayly that she was also assaulted and that she is looking for Kayly’s guidance. Kayly tells her that it is difficult to report sexual assault to the police. Kayly was certain that she identified the correct assailant even though he was wearing a mask because she recognized his voice and his nervous tic of “tapping the fourth finger on his right hand” (310). Shocked, Tracy runs away; she is now certain that her husband kidnapped and assaulted Kayly, as he also has this nervous tic.
The eyewitness, Francine Logan, returns to the police station and tells Jayne that the person with the suitcase in the elevator’s cell phone had rung, and the ringtone was “Bitter Sweet Symphony,” by the Verve. Jayne realizes that she recognizes the ringtone.
Jayne interviews Paige and asks her if she was having an affair with Sam. Paige denies it. Then, Jayne tells Paige she knows it was Paige with the suitcase in the elevator the day Bryden died. When Kilgour calls Paige’s cellphone, they hear the distinctive ringtone, and Paige asks for an attorney.
Paige realizes that her dream of marrying Sam and raising Clara is no longer possible. After her attorney arrives, Paige confesses to the detectives that Sam killed Bryden.
Paige tells detectives that on the day of the murder, Sam had come home in the middle of the day, argued with Bryden, then killed his wife. Then, he had called Paige on a burner phone to help him dispose of the body. Paige says that she had carried the suitcase containing the body, taking it down to the storage area and then throwing Bryden’s clothes in the dumpster. She claims that she did this because she loved him. She also confesses to lying when she claimed that Bryden was having an affair with Derek; she had wanted to distract the police from her affair with Sam. Paige is arrested, and so is Sam.
Lizzie is shocked to learn the police have arrested Sam for the murder. Donna feels relieved that her suspicions about him have been confirmed.
Sam insists to the police that he is innocent and has never owned a burner phone. Meanwhile, Lizzie sees that an anonymous post in the Facebook group states that Henry Kemp abducted and raped Kayly Medoff.
Jayne calls Derek to tell him that Paige has confessed to lying about his affair with Bryden. Alice is surprised and relieved.
In her jail cell, Paige mulls over how much Sam had taken advantage of her. She is angry he was “unwilling to commit” (329) to their relationship.
The narrative abruptly shifts into the past to reveal that six days before Paige’s arrest, she buzzed Bryden on the intercom from the parking garage and indicated that she needed to talk to Bryden urgently. Bryden let Paige in, after which Paige suffocated Bryden with a plastic bag.
Jayne interviews Sam, who insists on his innocence and says that Paige is lying. He says he has an alibi for the time of the murder and then confesses that he has a “drug problem” and had been with his drug dealer that afternoon.
Jayne tells Paige that Sam has an alibi for the time of the murder. Paige is furious that Sam lied to her about not having an alibi. (The narrative reveals that she had murdered Bryden so that she could be with Sam. However, when she realized that Sam “didn’t really care for her” (335), she decided to pin the murder on him instead.)
That evening, Jayne and Michael celebrate Jayne’s success at closing the case. Michael tells Jayne that a beautiful woman came up to him after his lecture that afternoon and “asked some very good questions” (336), then asked to meet for coffee. When Jayne expresses surprise, he reassures her that she has “nothing to worry about” (336).
The ending of She Didn’t See It Coming is largely typical of the “whodunit” domestic mystery genre, but Lapena introduces a significant twist. When Paige alleges that Sam murdered Bryden and then asked for her assistance in getting rid of the body, this initially appears to be the true resolution of the mystery. At first glance, the clues ostensibly fit. Sam does not have an alibi for the time of murder, Paige was in love with Sam and willing to do anything to help him, and she knew about the storage unit because she assisted Bryden in moving baby clothes into it. Even Detective Jayne Salter initially believes the claim, remarking to her colleague, “It amazes me how men can find women to do things like this for them” (320). However, this false resolution merely sets the stage for one final plot twist, when Sam confesses to having “a drug problem” and finally admits that his drug dealer is his alibi (333). This piece of information is designed to upend the entire portrayal of Sam up until this point, as Lapena has provided no direct evidence thus far that Sam struggles with addiction. This final twist, an unusual one for a whodunit, deepens the intrigue and complexity of the plot.
The final paragraphs of the novel act as an epilogue, providing a glimpse into the characters’ actions following the closure of the case. In this scene, Michael reveals to Jayne that an attractive woman came to his lecture and asked him to get coffee. The author has made it clear that this woman is Alice Gardner, who was researching Michael and decided to go to his lecture. This ominous cliffhanger implies that Alice intends to continue to insinuate herself into Jayne’s life even after the case has been closed, and the narrative also suggests that Alice may be trying to get revenge against Jayne for investigating her and her husband.
Notably, Michael did not recognize Alice from the media coverage of the murder investigation. In addition to preserving the underlying sense of danger and threat in the world of the novel, the last paragraphs also highlight the story’s focus on Betrayal in Intimate Relationships. The starkest of these betrayals can be found in Paige’s willingness to murder her best friend in order to replace Bryden as Sam’s romantic partner. However, the theme is also echoed in other characters’ actions, as when Alice is revealed to have betrayed and murdered a man that she had been dating. In a less gruesome way, Lizzie’s decision to post personal information about her sister’s brutal murder on a public Facebook group is also framed as a form of betrayal, for she never considered how her actions might impact her parents. These characters are all motivated by their own self-interest, and they show no regard for how their decisions might affect the lives of others.
