Chapter 18-Interlude 25Chapter Summaries & Analyses

Chapter 18 Summary

Aaron makes dinner for Carmen at his flat. When she points out how spartan and spare his place is, he reveals that after his last girlfriend moved out, he never replaced the furniture that she had taken with her. When she asks him about his relationship with his late father, Aaron explains that his father had been distant and uncommunicative and that their relationship soured many years ago when his father moved the family to the city. Carmen points out that Aaron is also distant and uncommunicative. She argues that the two probably had more in common than Aaron realized. Their chat is interrupted by a call from Sergeant King, who states that the cabin has been located.

Chapter 19 Summary

Aaron speaks with Bree, who has been released from the hospital. She asks him about the cabin, Kovac, and the possibility that someone else had been using the cabin recently.

Interlude 18 Summary: “Day 5: Saturday Night”

Jill tells Alice that if she leaves the group, she cannot take her phone. Jill searches for it in Alice’s backpack but doesn’t find it. Beth tells Jill that the phone is in Alice’s jacket, then lunges at Alice. Alice is furious, but Beth points out that Alice was only too happy to search her bag when she thought Beth was hiding food. Beth wrests the phone away from Alice, but Alice fights back. Beth refuses to back down and smacks Alice as hard as she can.

Chapter 20 Summary

Aaron and Carmen make their way back to the lodge. Lauren and Margot are also there, hoping that Alice will be located soon.

Beth and Alice continue to fight. Bree tries to pull them apart but ends up down on the floor with them. Alice gains the upper hand and smacks Beth’s head to the floor. Beth sees stars.

Chapter 21 Summary

Aaron and Carmen reach the cabin after a difficult hike through forbidding and treacherous terrain. They cannot help but be struck by the structure’s foreboding aura. They can easily imagine Martin Kovac using it during his serial killing spree, just as they can imagine Martin’s son Sam using it during his many years of drug trafficking. The cabin is well camouflaged, and Aaron observes that it must have been difficult for the women to find. There are two shallow graves; one contains the body of a dog, while the other contains a human skeleton. They will have to wait for analysis, but everyone seems to think that the body is Martin Kovac’s fourth victim, who was never located. Inside, they see signs of a recent struggle and fresh blood on the floor.

Interlude 20 Summary: “Day 3: Saturday Night”

Lauren breaks up the fight, which by this point involves all of the women. Everyone is battered and bloody, and Alice is crying.

Interlude 21 Summary: “Day 3: Saturday Night”

In the aftermath of the fight, tensions remain high. Jill insists that they all calm down and go to sleep, but Alice curses at Beth and threatens to fire Bree.

Chapter 23 Summary

The search party sets out along the trail that Alice most likely took when she left the cabin. The route is steep and rocky, but they can follow it easily. When they have been walking for a while, Aaron hears a soft beep and realizes that his phone has service. They spread out, hoping to reach the location from which Alice called Aaron. Fifteen minutes later, they find Alice’s backpack.

Interlude 22 Summary: “Day 4: Sunday Morning”

Chapter 24 Summary

Aaron recalls one of the rangers saying that in almost every case, when a missing person’s possessions are located, their deceased body is not far away, simply because the conditions are too harsh for people to abandon their clothing, packs, and supplies. Although he hopes that the maxim will not prove true in this case, Alice’s body is indeed found near her backpack.

The watcher observes Alice as she silently slips away from the cabin.

She assumed that Beth killed Alice and wanted to help cover up the crime. Their mother was devastated when Beth was incarcerated for the first time, and Bree explains that she wanted to save their mother from additional heartbreak. Beth denies having killed Alice and is angry and offended that Bree believes her to be capable of murder. Bree is sure that Beth is betraying her by not admitting her role in Alice’s death, and Beth is sure that her sister is accusing her of a crime that she did not commit.

Chapter 18-Interlude 25 Analysis

While the majority of the novel focuses on the events surrounding Alice’s disappearance and death, this section makes a notable departure from the theme by focusing on a scene in which Aaron and Carmen share a homemade dinner in Aaron’s flat. By creating a deeper sense of the investigators’ personal lives and their candid relationship with one another, Harper deliberately humanizes both characters and allows them to transcend the flat, stereotypical roles that the murder-mystery aspects of the plot require them to play. For example, when Aaron shares details of his fraught relationship with his father, Carmen gains a fuller picture of him and displays her emotional intelligence when she suggests that Aaron’s unwillingness to form emotional attachments sounds very similar to his description of his father. Her comment allows Aaron to realize that he might not have gotten along with his father because they were too similar, and this internal revelation will become a key step on Aaron’s healing journey. Thus, it is clear that the investigators’ platonic friendship proves deeply beneficial, counteracting Aaron’s inclination to remain largely solitary. 


This section of the novel also contains a description of the physical altercation that breaks out amongst the women shortly before Alice leaves the group, intensifying the novel’s focus on The Instability of Group Dynamics. The women’s escalating strife reflects multiple fraying relationships, and these developments make their survival situation all the more perilous as the last vestiges of trust and respect utterly break down into chaos. For example, the corporate hierarchy amongst these coworkers dissolves when Alice refuses to respect Jill’s declaration that Alice’s phone—the only communication device they have—should stay with the group. In this moment, Alice’s history of bullying treatment toward Beth comes back to haunt her when Beth strikes back physically and Bree steps in to break things up. However, it is vital to note that this altercation arises from several key factors. Although Alice may appear to be thinking only of herself, she is worried about Margot, and her desire to head back to the lodge alone reflects The Extremity of Parents’ Protective Instincts. However, her unwillingness to listen to Jill, although rooted in her desire to help Margot, also stems from her general lack of respect for her peers and coworkers. 


Similarly, Bree’s attempt to end the violence that breaks out between the women reflects both her interest in serving as a peacekeeper and her instinctive desire to protect her sister despite her antipathy toward Beth. In fact, Beth and Bree’s relationship remains a key focal point during the investigative chapters when the details of Alice’s death are finally revealed, and Bree’s choice to hide Alice’s body is complex. Her actions reflect her desire to protect her sister—and indirectly, her mother. She is worried not that a second incarceration will be difficult for Beth, but that such a consequence would cause her mother emotional distress. Additionally, the very fact that she suspects Beth of the murder indicates the lack of trust and respect in the sisters’ relationship. 


The ominous setting of the Giralangs becomes especially prominent as King and Aaron set out to search for the women, but although the treacherous terrain and remoteness of the area are meant to heighten the tension of the narrative, the primary danger in these scenes is ironically human in origin. The cabin becomes the primary symbol of this idea, for over the years, it has been used by killers, drug traffickers, and other criminals, and its foreboding presence exudes a sense of malevolent sentience, as suggested by the author’s deliberate use of personification and stark, vivid imagery. As the narrative states, the cabin “was well camouflaged against the muted tones of the bushland, and it looked purposefully lonely. From its gaping, vacant windows to the unwelcoming sag of the door, it reeked of desperation” (245). By imbuing this ill-fated space with the darkest of human emotions, Harper sets the stage for the suggestive evidence that the detectives find: animal and human remains, along with the clear evidence of a recent fight. The dramatic depiction that characterizes this scene also typifies Harper’s work as a whole, and several of her other novels make use of similarly remote settings to build a sense of mystery and dread.
