Chapter 10 Summary

Will uses his phone to take photos of the backpack and its surroundings. Delilah says it’s Mercy’s backpack. Nadine puts gloves on and carefully opens the backpack. Inside is a badly damaged notebook, some clothing, and an old phone. Mercy was apparently leaving, but they don’t know why she went to the bachelor cottages.

Will realizes that Dave must be hiding at Camp Awinita, on the other side of the lake. Delilah gives Will and Sara directions to get there by canoe, and Nadine reluctantly agrees not to tell Biscuits what they’re doing.

Delilah tells them that Dave habitually carries a switchblade, and Sara gets nervous. She and Will hike to the equipment shed, where the canoes are kept. The same shed houses all the fishing equipment, which Christopher meticulously organized. They note that none of the knives appear to be missing. Before they leave, Will grabs a knife, some duct tape, and zip ties.

Following Delilah’s directions, they row to Camp Awinita. Sara drops Will on the beach and then takes the canoe offshore while he finds and secures Dave. Dawn is breaking as Will moves toward the old campfire ring. Dave is cooking fish and has a boning knife close at hand. Mentally preparing for a fight, Will steps into the clearing.

Will pretends that he was just looking for Camp Awinita. Accepting a beer from Dave, he sits down near the fire, making sure to sit so that he can easily access the knife in his boot. He considers when to announce that he’s a GBI agent. Technically, anything Dave says before that will be inadmissible in court, and though he’d love to punish Dave, putting him through the justice system will be revenge enough.

Will leads Dave into a conversation about Mercy, his marriage, and Jon. Dave tells him about being adopted by the McAlpines: how Bitty took care of him and how Cecil beat him. In turn, Will gives Dave an edited version of what happened to him after he aged out of the home, though he still doesn’t reveal that he’s with the GBI. Dave asks Will what it’s like to be married to someone “normal,” after what they went through as children.

Will finally says that he knows what Dave did to Mercy. Dave seems unconcerned and talks about Mercy in the present tense. Will realizes that Dave thinks they’re talking about his strangling Mercy earlier that day. He finally admits that he’s a GBI agent and reads Dave his Miranda rights.

Dave moves closer to his boning knife and tells Will to leave. Will casually exposes his own knife, and they both stand up. Dave opens what Will realizes isn’t a switchblade but a butterfly knife, a more dangerous weapon. While Dave is distracted by his own knife, Will kicks him in the groin with all his strength.

The chapter closes with a letter from Mercy to Jon, dated January 16, 2014. Mercy has had custody of Jon for three years. She recalls that when she told Dave she was leaving him, he strangled her to the point that she lost consciousness. His eyes were blank while he did it. However, she also tells Jon about how Dave was good to her and took care of her after her car accident. That is why she still loves him despite everything.

Chapter 11 Summary

Faith arrives at the sheriff’s office. It’s nearly six o’clock in the morning, and she drove for five hours. While driving, she listened to the voice files Will sent her. The first recording was Will’s interview of Delilah, including Mercy’s personal history, from Cecil’s abuse to her dysfunctional relationship with Dave. The second recording is of Will arresting Dave and then apparently kicking him in the groin.

Amanda calls Faith; she’s at the hospital across the street, and so is the sheriff, because Dave is being held there. Faith walks over, and Amanda asks her to handle Dave’s interview. In the hallway, they see Sara and Delilah. Sara tells them that Dave threatened Will with a butterfly knife and they’re analyzing a bloody handprint on his shirt. She also tells them about the backpack and its contents, including the notebook. Sara and Delilah leave to look for Jon in town, while Faith and Amanda go to Dave’s room.

Will meets them outside Dave’s door. Amanda leaves to find Biscuits. Will warns Faith not to underestimate Dave and tells her about their history at the children’s home. Faith points out that according to his rap sheet, Dave is four years younger than Will and wonders why they were grouped together. However, Will knows that Dave is only two years younger and realizes that the McAlpines “aged him down” to keep receiving benefits (224). He also admits that though he’s sure Dave is the killer, Sara isn’t.

Amanda returns with Biscuits, who she says has “agreed” to give them the investigation. Biscuits thinks that Mercy’s death is just the final act in her and Dave’s abusive relationship and that she was always “trouble” and ruined Dave’s life.

Faith and Biscuits interview Dave, and Faith is surprised at how innocuous he looks. Dave still thinks they’re investigating Mercy’s strangling, but Faith tells him that Mercy is dead. He starts to cry. On his phone are missed calls from Mercy, which loaded when he was taken to the hospital.

Faith sees seven missed calls but only one voicemail (from the last call). They listen to it. Mercy, hysterical, pleads for his help. She begins speaking to someone on the scene, asking what they’re doing there. The message cuts off abruptly. Faith realizes that Dave didn’t kill Mercy; in leaving this message, she gave him an alibi.

Chapter 12 Summary

Sara mentally prepares for the autopsy she’ll be performing on Mercy soon. Will tells her that the lodge’s road was washed out by the rain, and they’ll need utility terrain vehicles (UTVs) to get back there. However, the washout has a positive aspect: Everyone is still trapped there except Penny, the bartender, whom Faith has gone to interview at her house.

Will asks Sara if she wants them to step back from the investigation, and she knows that this is a “marriage-defining moment” (238). She knows he wants to continue, especially to pass Mercy’s last words on to Jon. She agrees to stay, at least for the day. He asks why Sara doesn’t believe that Dave killed Mercy. She points out that several people at the lodge fit the profile of Mercy’s killer. He tells her that Christopher has $200,000 in his bank account, while Mercy doesn’t even have a bank account.

When a trailer truck pulling two UTVs pulls up, Will takes one back to the lodge, leaving the other for Sara to return later. Sara goes down to the morgue, where Amanda is waiting. She briefly interviews Sara as a witness to the scene rather than a medical examiner. Sara tells Amanda that she would guess someone in the family killed Mercy because of the lodge sale.

During the autopsy, Sara is again struck by the attack’s viciousness, as well as the signs of long-term abuse on Mercy’s body. She reflects on all the feelings this investigation must be raising in Will. She counts at least 20 stab wounds, and Nadine begins to cry, feeling that she should’ve done something to help Mercy long ago. Mercy’s X-rays reveal more abuse injuries, and Sara sees a small blur and realizes that Mercy was pregnant.

Chapter 13 Summary

Faith drives out to Penny Danvers’s house. Faith feels a connection to Mercy: They were both young, single mothers, only Faith was lucky enough to have a supportive family. As she drives, she considers the timeline. She can use Mercy’s calls to Dave to determine how and when Mercy got to the bachelor cottages. She wonders what scared Mercy badly enough to both run and call her ex-husband for help.

A bird flies into Faith’s windshield, and she instinctively swerves. Her car spins and gets stuck in the muddy ditch. She digs it out and she sees a woman and a dog standing nearby. It’s Penny, and Faith drives her and her dog to her house so that she can interview her.

Penny tells Sara that when Mercy got pregnant at 15, the community forced her to leave school. She also remembers how after Mercy got sober and left Dave, Cecil made sure that no one in town would help her. Penny admires Mercy, saying that before Mercy took over, the lodge was barely breaking even. She turned it around, mostly by offering alcohol, which Cecil didn’t, and using the proceeds to renovate the cottages. Penny knows firsthand how hard Mercy worked to stay sober because they were both in recovery and depended on each other.

Faith asks Penny about something she heard in Will’s recording about “Christopher and Gabbie” (271). Penny says that Gabbie was hired from Atlanta one summer. Everyone loved her, but Gabbie and Mercy were best friends. One night, they were drunk, and Mercy drove off Devil’s Bend into a gorge. Gabbie was killed, and Mercy had a sliced face and broken bones. She should’ve gone to prison for it, but Cecil pulled strings, and the incident didn’t appear on her record. Penny tells her that’s when Mercy went into recovery but reflects that it might’ve been better if Mercy had gone to prison instead of moving home, considering how her parents treated her.

Faith’s phone rings, and she steps outside to answer it. Will tells her that Mercy was pregnant. Faith tells Will that Penny sometimes said Mercy had sex with the guests. They consider the ramifications. Faith’s tire is flat, so Penny offers to take Faith to the lodge on her horse, Rascal.

Chapters 10-13 Analysis

These chapters continue to set the two genres in opposition as the locked-room nature of the mystery creates obstacles to the regular operation of the police procedural. In Chapter 10, Will reflects on how he and Sara “knew what should be done” (177). He muses, “The arson investigator would want to take photos, comb through the debris, collect samples, run tests, search for accelerant, because something had clearly been used to make sure the cottage burned” (177). However, their investigation is hampered by a sheriff who won’t investigate and initially won’t turn over the case, and further complicating matters is a massive rainstorm that washes out the road to McAlpine Lodge. The novel describes technical details like the autopsy and the state of Mercy’s body in graphic terms, in line with the police procedural genre:

Mercy’s eyes were slit open, her corneas clouded. Her mouth was agape. Dried blood and debris patched her pale skin. Several shallow stab wounds had gouged out the flesh of her neck. […] Every inch of exposed skin showed the brutality of her death (248).

The description are equally graphic regarding Sara’s examination of past trauma to Mercy’s body, emphasizing the cruel, brutal, and sustained abuse she endured. However, Amanda and Faith’s arrival in town and then at the lodge creates a dynamic that is more aligned with the Will Trent series. The novel develops Faith’s character through her interactions at the hospital and with Penny Danvers before she comes back into contact with her partner, Will. Faith is down-to-earth, funny, and full of pop culture references. Her assessments lighten the mood, as when she reflects that she “had somehow framed [Dave] in her head as somewhere between Moriarty from Sherlock Holmes and Wyle E. Coyote” (229). She’s also self-aware and self-deprecating, as when she muses that Dave is good-looking “in a bedraggled, high-school-prom-king-gone-to-seed kind of way. He’d probably slept with every other woman in town and had a $20,000 gaming set-up inside his rented trailer. Which was to say, exactly Faith’s type” (229). Faith also hates nature and adds a humorous note through her assessment of the horse, Rascal, “[floating] up the mountain on a cloud of flatulence” (303).

In these chapters, Will continues to struggle with his past, specifically regarding Dave, which continues to develop the theme of How the Past Affects the Present. Will’s personal history and bias lead him to still focus on Dave as the killer. This is where Sara proves a good partner for Will, both personally and professionally. On a professional level, Will is unusually emotional and involved in the investigation, and Sara balances him, pointing out his bias. On a personal level, she’s willing to delay their honeymoon when she sees how important the case is to him. Throughout, though Will finds it difficult to maintain objectivity, he reflects on the trajectory of his life compared to Dave’s and on how the difference seems mainly due to his having support and making a determined effort to change: “He had spent the first eighteen years of his life expecting people to do brutal and violent things, then the subsequent years doing everything he could to stop them” (185).

When Penny tells Faith about the car accident that killed Mercy’s friend Gabbie, it not only explains the scar on Mercy’s face but foreshadows several revelations later in the novel about that night: Mercy’s father raped Gabbie and was driving the car but staged the scene of the wreck to implicate Mercy as the driver; Mercy was haunted by the incident for years, and Dave knew what really happened but kept Cecil’s secret; and Landry (the lodge guest with the tattoo incorporating Gabbie’s name) is Gabbie’s brother. These revelations and the painful effect of the truth after years of deception introduce another of the novel’s main themes: The Impact of Lies and Secrets.
