Her Last Breath

Detective Layla Washington paces the command center, her eyes fixed on the latest updates from the rescue team. A young woman is trapped deep within the Devil’s Staircase, a treacherous cave system in the Cascade Range. Severely injured and confined to a tight, dark space, the woman's condition is rapidly deteriorating. The rescue efforts are hampered by the cave's narrow passages and lack of communication signals, making the operation even more perilous.

Washington, a seasoned detective, has been delving into the history of the Devil’s Staircase, a place renowned for its beauty and danger. She wonders what drove the woman to venture so far alone, suspecting either reckless exploration or a desperate escape from something far more sinister. The discovery of a body outside the cave, a victim of a gunshot, adds a layer of complexity to the situation. The trapped woman is believed to have crucial information about the murder.

Despite the rising groundwater and her injuries, the woman's survival is a testament to her remarkable resilience, described by the Finnish term 'sisu.' Washington, impressed by her determination, hopes she can hold on until the rescuers can free her. The detective is eager to hear the woman's account of what transpired, as it could provide vital clues to solving the homicide.

Tess DeWater stands hesitantly at her apartment door, plagued by her generalized anxiety disorder as she prepares to leave for a caving expedition with her best friend, Allie Merritt. Despite her fears, she convinces herself that she has prepared for every possible scenario and locks the door, determined to face the day. As she joins Allie in her black Subaru Outback, the tension between them is palpable, with Allie’s carefree attitude clashing with Tess’s cautious nature.

During the drive, Allie shares a harrowing story about a prospector who died in the Devil’s Staircase cave system, using it to illustrate the dangers of caving alone. Tess, though visibly unnerved, tries to maintain a facade of calm. The conversation shifts to Allie’s successful travel blog and the dynamics of her relationship with her boyfriend, Ethan, whom Tess has excluded from this trip. Allie’s storytelling and driving style heighten Tess’s anxiety, but she remains resolute, reminding herself that they will stay in the beginner-friendly section of the cave.

As they approach the remote town of Flour Gold, the landscape reflects the decay of a once-thriving mining community. Tess’s unease grows with each mile, and she questions the wisdom of the trip, but Allie reassures her that they will be safe. The chapter ends with the ominous lyrics of My Chemical Romance’s “Famous Last Words” playing in the car, mirroring Tess’s nervous laughter.

At the entrance of the Devil’s Staircase cave, Tess DeWater feels a surge of anxiety. The cave appears much smaller and more ominous than she had imagined, hidden and surrounded by vegetation, giving it an eerie, almost sinister appearance. Allie reassures Tess that the cave is larger on the inside, but Tess remains anxious, noting the presence of a parked Jeep in the distance, which suggests the area might be frequented by others, possibly illegally.

Before entering, Allie equips Tess with a harness for potential vertical descents, which Tess finds more daunting than she expected. Allie also attaches GoPro cameras to their helmets, ostensibly to document their adventure but also as a safety measure in case of an emergency. As they prepare to enter, Allie mentions that the cave is rumored to be a portal to Hell, adding to the ominous atmosphere. Tess feels a mix of excitement and fear, reflecting on the contrast between her cautious nature and Allie’s adventurous spirit.

Inside the cave, the environment is dirty and vandalized, with graffiti, trash, and evidence of drug use. As they proceed, they encounter a man named Jacob, who identifies himself as a representative of Green Ridge, checking for signs of white-nose syndrome in bats. Jacob’s presence is unsettling, and he makes inappropriate comments, leading Allie to firmly reject his offer to guide them. Despite Tess’s concerns about the potential danger, Allie dismisses her worries, and they continue deeper into the cave, leaving Jacob behind.

At Sacred Heart Medical Center, Detective Layla Washington interviews Tess DeWater, noting her extensive injuries and the survivor's remarkable resilience. Washington probes Tess about her encounter with Jacob at the cave entrance, asking if his behavior seemed rehearsed or suspicious. Tess reveals her suspicions about Jacob, including his inappropriate comments and his fixation on the GoPro cameras on their helmets, suggesting he may have been sizing them up as potential targets.

The conversation shifts to Allie’s reaction to Jacob, with Tess explaining Allie’s confrontational nature and her tendency to stand up for herself and others. Washington carefully navigates the delicate topic of whether Allie’s response might have provoked Jacob, emphasizing that she is not blaming the victim. Tess reflects on her complex relationship with Allie, describing their childhood and how Allie’s family took her in, making them like sisters. She admits to criticizing Allie’s confrontational approach during the caving trip, highlighting their fundamental differences in handling stressful situations.

Tess describes the eerie and disorienting nature of the cave, emphasizing how it defies human understanding and logic. She explains the cave’s lack of clear walls, ceilings, and floors, and the claustrophobic and three-dimensional navigation required. Washington listens intently, recognizing the profound impact the cave had on Tess’s mental state and the potential dangers of becoming lost within its labyrinthine tunnels. The chapter ends with Washington preparing Tess to recount the next series of events, setting the stage for the unfolding tragedy.

Deeper into the Devil’s Staircase, the cave grows disorienting and foreboding. Allie’s confident demeanor contrasts sharply with Tess’s growing anxiety, especially as they navigate the cave’s unique challenges, such as fragile stalactites and the risk of foul air. Allie shares her knowledge about the cave’s ecosystem and the dangers they might face, including aggressive spider crickets and the importance of recognizing signs of poor air quality.

Tess reflects on her past, recalling a game called Changeling where she excelled at deception, and her feelings of inadequacy compared to Allie’s bravery. Allie’s history with a near-death experience from a venomous snake bite in Mexico adds depth to her character, revealing her stoic and humorous approach to life-threatening situations. The chapter also delves into Tess’s secretive behavior, including her habit of entering Allie’s apartment and exploring her belongings, uncovering Allie’s hidden firearms and her less publicized hobbies.

The tension builds as Allie leads Tess to a steep vertical drop known as the Great Wall. Allie teaches Tess how to use the descender and reassures her, drawing on their shared history of facing fears together. Despite her reservations, Tess trusts Allie and begins her descent, feeling a mix of fear and empowerment. Suddenly, Tess experiences a bolt of intense pain in her head, leaving the reader in suspense.

Tess’s descent down the Great Wall turns perilous when her hair becomes entangled in the descender. The pain in her scalp grows unbearable as she struggles to free herself, her head immobilized by the tight grip of the rope and metal racks. Allie, hearing Tess’s cries of distress, reassures her and promises to come to her aid, but Tess, feeling vulnerable and embarrassed, decides to act on her own. Using her Swiss Army knife, she carefully cuts her hair, a task that requires both precision and courage. Despite the discomfort and risk, she manages to free herself, feeling a surge of empowerment and relief. Allie, impressed by Tess’s resourcefulness, praises her for handling the situation with such composure. This moment of triumph boosts Tess’s confidence, and she is eager to face more challenges in the cave.

However, their sense of accomplishment is short-lived. Allie suddenly notices something amiss and signals Tess to dim her headlamp. Pointing upwards, she indicates that something or someone is watching them from the darkness above. The chapter ends with a palpable sense of impending danger as Allie and Tess prepare to confront the unknown lurking in the shadows of the cave.

Still reeling from the near-disaster at the Great Wall, Tess recounts to Detective Washington the strange red glow they observed at the top of the Devil’s Staircase cave. The glow was subtle and fleeting, but it left both Tess and Allie deeply unsettled. Allie, trying to ease their fears, climbed back up to investigate and reported finding nothing, attributing the phenomenon to another group of cavers or a cave hallucination, known as a 'bogey.'

As they ventured deeper into the cave, the environment became increasingly surreal and unsettling. The rock formations were smooth and alien-like, with flowstone and cave pearls adding to the otherworldly atmosphere. Allie mentioned a surprise further down, hinting at phenomena that defy surface physics. The deeper they went, the more Tess felt the weight of the earth above them, and the more she questioned Allie’s motivations and recent behavior.

Tess and Allie’s conversation revealed underlying tensions in their friendship. Allie expressed feeling like they had become strangers, and Tess reflected on Allie’s recent mysterious trip to Costa Rica and her troubles with Ethan. Allie’s cryptic comments and jokes about the GoPro cameras recording their journey added to the sense of foreboding. The chapter ends with Allie’s enigmatic question, 'Why do you think you’re here, Tess?'

Tess recounts to Detective Washington the unsettling experience of hearing footsteps behind her and Allie in the Devil’s Staircase cave. The footsteps matched their pace perfectly, and when Tess stopped, the footsteps also ceased, suggesting a deliberate and calculated pursuit. Allie, however, dismissed Tess’s concerns, attributing the phenomenon to the cave’s unique acoustics, which can create perfect echoes. Despite Allie’s reassurance, Tess remained suspicious, fearing that someone was using the cave’s acoustics to mask their presence and follow them undetected.

The conversation then shifts to Tess’s troubled past, revealing the deep-seated trust issues that stem from her childhood. Her mother, who struggled with drug addiction and delusions, subjected her to severe emotional and physical abuse, including burning her with bleach. It was Allie who encouraged her to speak up and report the abuse, leading to her eventual adoption by Allie’s family. This experience shaped Tess’s desire to pursue law, driven by a passion for justice and a commitment to helping others in similar situations.

Detective Washington suggests that Tess and Allie’s decision to keep going deeper into the cave, rather than turning back, may have been the key to their survival. She argues that if they had turned around, the stalker would have had an easier opportunity to attack them. This perspective helps Tess see that her instincts and decisions, though fraught with fear, were ultimately necessary for their safety. The chapter ends with Allie leading Tess to a dead end in the cave, hinting at a ‘surprise’ that has yet to be revealed, and raising questions about Allie’s true intentions and awareness of the danger they face.

Tess and Allie stand at what appears to be a dead end, but Allie excitedly reveals it as the entrance to the Drainpipe, or Bishop’s Crawl. The narrow, two-foot-wide tunnel is lined with sharp rocks and enveloped in a thick, oppressive darkness. Allie, undeterred, explains the challenges of navigating the tight space, recalling a prospector who met a tragic fate in a similar tunnel. Despite her hesitation, Tess feels a faint breeze, which Allie interprets as a promising sign of more cave beyond the tunnel. Allie’s encouragement and reminders of Tess’s recent successes help, but Tess’s fear remains overwhelming, and she cannot bring herself to enter the Drainpipe. Sensing her friend’s distress, Allie suggests they can return another time, but their moment of decision is interrupted by the reappearance of the red glow, now closer and more menacing. The red light intensifies and hovers in the air, heightening the sense of impending danger. Tess reflects on the day’s events, feeling a mix of pride in her earlier accomplishments and disappointment in her inability to face the final challenge. The red glow’s reappearance adds a layer of urgency and fear, suggesting that their pursuer is closing in.

The red light in the tunnel intensifies, revealing a human figure wearing a red headlamp. It is Jacob, who admits to lying about his affiliation with Green Ridge and reveals himself as a private contractor. Recognizing the threat, Allie secretly opens her survival knife and positions herself protectively in front of Tess. Jacob demands that Allie and Tess tie their wrists with zip ties for his safety, claiming he wants an apology for the earlier confrontation. Allie, refusing to comply, offers him fifty thousand dollars from her bank account in exchange for their freedom. Jacob, intrigued but skeptical, considers the offer but ultimately rejects it, revealing that he has a concealed handgun. The tension escalates as Allie remains defiant, and Jacob acknowledges her as a formidable opponent. Later, in the recovery room at Sacred Heart Medical Center, Tess struggles to recount the traumatic event to Detective Washington, revealing that Jacob shot Allie in the head.

The aftermath of Allie's shooting is etched in Tess's mind as she recounts the gruesome details to Detective Washington. Blood splattered the tunnel walls, and the echo of the gunshot still rings in her ears. Detective Washington reassures Tess that Allie's actions were heroic and that the responsibility for her death lies solely with Jacob, the attacker. The detective emphasizes that the attack was not a random robbery but a premeditated plan to make both women disappear, as evidenced by the zip ties Jacob brought with him.

Despite the trauma, Washington gently pushes Tess to describe how she managed to escape. Tess explains that she was cornered and had no choice but to flee down the Drainpipe, a narrow and terrifying tunnel that she had previously been too afraid to enter. The detective marks this point as a significant depth in the cave, acknowledging the extreme danger Tess faced. Tess’s decision to hurl herself headfirst into the Drainpipe was a desperate act of survival, driven by the immediacy of the threat and the memory of Allie’s sacrifice.

Still reeling from the shock of Allie’s shooting, Tess finds herself crawling through the claustrophobic Drainpipe, a narrow and treacherous tunnel in the Devil’s Staircase cave. She lands hard on her stomach, unable to turn around or stretch her arms due to the tight space. The tunnel is cold, wet, and pitch-black, and she can hear Jacob’s boots stomping and his angry shouts as he follows her down the chute.

Tess kicks at Jacob when she feels his breath on her ankle, then continues to crawl deeper, using rocks as handholds and footholds to pull herself through. She hears his huffing breaths and the metallic clicking of his combat knife scraping against the rock. The tunnel narrows, and she realizes it is a dead end, leaving her trapped and terrified, with nowhere to go and Jacob closing in.

Detective Washington provides insight into the tactical reasons behind Jacob’s use of a red headlamp, explaining that it preserves night vision and is harder to detect. She also discusses the impracticality of using a gun in such a confined space, suggesting that Jacob’s knife was a more effective weapon for his purposes. The chapter underscores the intelligent planning behind Jacob’s ambush and the dire situation Tess found herself in, fighting to survive in a claustrophobic and deadly environment.

Still reeling from the claustrophobic chase through the Drainpipe, Tess continues her account to Detective Washington. She describes the dangerous cave-in she encountered, a blockage of loose rocks and a large sandstone boulder that created a narrow gap. Despite her initial hesitation, Tess realized the gap was too small for Jacob to follow, giving her a crucial advantage.

She details the harrowing process of removing her gear and pushing it through the gap, followed by her own body. Flattening herself and exhaling, she managed to squeeze through the tight space. Once on the other side, she turned to face Jacob, now blocked by the boulder. Tess realized that Jacob was fixated on the GoPro camera mounted on her helmet, which had been recording the entire time, including Allie’s murder. This realization gave her a newfound sense of power and control over the situation.

Tess tells Washington that she confronted Jacob, informing him that she had recorded his crime and vowed to ensure he would be held accountable. The detective acknowledges Tess’s bravery and strategic thinking, recognizing that she had effectively turned the tables on her pursuer. However, the moment is tinged with grief as Tess reflects on the loss of her best friend, Allie, and the emotional toll of the ordeal.

After her confrontation with Jacob, Tess is left alone in the dark tunnel, feeling a mix of relief and dread. She knows she must remain hidden to survive but is now trapped deep underground with limited resources. Detective Washington reflects on her own experiences with disorientation and the fragility of the human mind, drawing parallels to Tess’s situation. She emphasizes the importance of establishing a timeline and asks Tess how long she waited behind the cave-in. Tess admits she lost track of time, focusing on conserving her headlamp battery and the remaining charge on Allie’s GoPro.

Lying in the narrow tunnel, Tess experiences physical and psychological torment. Her body is numb and in pain, and she listens for any signs of Jacob, hearing strange noises that may be hallucinations. She knows she has to wait until help arrives, relying on the surface watch set up by Allie, which will alert Ethan if they don’t check in.

Tess’s conversation with Washington shifts to her relationship with Allie’s boyfriend, Ethan. She describes him as a decent but simple person, noting that he and Allie seemed like a perfect couple. However, she sensed a guardedness in Ethan and a serious issue weighing on Allie before the trip. Tess’s hope for rescue is bolstered by the knowledge that Ethan will report them missing, forcing Jacob to flee.

Detective Washington informs Tess that Jacob used their phones to send deceptive text messages to Allie’s boyfriend, Ethan, and Tess’s manager, Sandra. These messages, mimicking the women’s voices, demonstrate Jacob’s intelligence and thorough planning. Washington suspects deeper motives, as a random stranger shouldn’t know so much about Tess and Allie to execute such a convincing deception.

Tess recalls a poignant memory of Allie from a camping trip where Allie saw wild horses and envied their freedom. This memory symbolizes Allie’s desire for independence and adventure. Washington reflects on the complexity of the case and the need to investigate Allie’s past, including her legal troubles, which she had kept secret from Tess.

Washington reveals that Allie is under federal investigation for wire fraud, a revelation that shocks Tess. Despite their close friendship, Allie had kept significant secrets, raising questions about her true motives and the events leading up to their caving trip. Tess struggles to reconcile this new information with her memories of Allie.

While hiding in the tunnel, Tess heard the killer singing and a mechanical screeching sound. The song’s lyrics, 'The man downstairs, he waits and he waits,' and the rhythmic clicks add a haunting element to the narrative, suggesting a deeper, more personal motive behind Jacob’s actions.

Jacob Herman, undeterred by the physical and auditory damage from firing his gun, uses a scissor jack to lift a boulder blocking the Drainpipe. The tension is palpable as the boulder shifts, and Jacob, driven by his father’s lessons on power and dominance, continues to work the jack. Realizing she is no longer safe, Tess retreats deeper into the cave, crawling through the narrow, cold, and wet tunnel.

As Jacob closes in, Tess pretends to be stuck, luring him closer. Seizing the moment, she stabs him in the face with Allie’s knife, surprising him and causing him to retreat. The two engage in a psychological battle, with Jacob taunting Tess about Allie’s secrets and his plans to dispose of their bodies. Tess, maintaining her composure, continues to crawl backward, keeping Jacob at bay with her knife.

The tunnel spirals downward, and Tess understands that the deeper she goes, the more dangerous the cave becomes. She recalls the cave’s treacherous features, including Razor Alley and the Chimney, and realizes that even if she manages to kill Jacob, his body would block the tunnel, sealing her inside. The chapter ends with Tess’s realization that her only chance of survival is to keep moving deeper into the cave, despite the increasing risks.

Still reeling from the psychological and physical toll of her confrontation with Jacob, Tess continues to crawl deeper into the cave. Jacob, reflecting on his father’s lessons about power and dominance, taunts her relentlessly, trying to wear her down. Despite the strain, Tess remains resilient, using her knife to keep him at bay. Aware that her only chance of survival is to outlast Jacob, she maintains her composure and continues her descent.

Tess and Jacob engage in a tense negotiation. Jacob proposes a deal: she gives him the GoPro memory card and her knife, and he will let her live. Recognizing the futility of the situation, Tess agrees but cleverly deceives Jacob by giving him one of Allie’s spare memory cards instead of the real one, which she keeps hidden and still recording. Believing he has outsmarted her, Jacob reveals his face, only to realize too late that he has been duped.

The chapter ends with Jacob’s realization that Tess has outmaneuvered him, and he vows to kill her. Tess, now with footage of Jacob’s face, understands the gravity of her situation but remains determined to survive.

Tess reveals to Detective Washington her plan to preserve the footage of Allie’s murder by either giving the GoPro memory card to the police or swallowing it to ensure it would be found during her autopsy. Washington is impressed by Tess’s resourcefulness and resilience, acknowledging the extreme measures she took to ensure the evidence would be preserved.

Tess admits that her motivation extended beyond mere survival; she wanted to ensure Jacob paid for his crimes, even if it meant killing him. Washington shares her experience with homicides, explaining how she manipulates killers into confessing. Tess is surprised by Washington’s candor about the necessity of sometimes acknowledging the need to eliminate certain threats.

Washington then introduces a new theory: there was a second killer involved in the attack. She presents evidence of a partial glove print in blood found on Jacob’s Jeep, suggesting someone else was present and may have helped clean the crime scene. Tess is initially dismissive but becomes intrigued when Washington reveals the discovery of Allie’s pregnancy test receipt in her car, leading her to consider the possibility that Allie’s boyfriend, Ethan, might be involved.

The revelation that Allie might have been pregnant sends a wave of shock through Tess. Washington suggests that Ethan’s reaction to the news of Allie’s pregnancy might have led him to hire Jacob to eliminate her. The chapter ends with Tess and Washington agreeing to work together to uncover the truth and bring the true killer to justice.

Jacob reflects on the meager compensation for his job, rationalizing the risks and the necessity of the money to sustain his life. Despite understanding the transient nature of life and the insignificance of one more death, he acknowledges the difficulty of the task at hand. In the confined space of the Drainpipe, Jacob strategizes about how to use his gun, considering the risks of noise and ricochet. He decides to shoot at a downward angle to minimize these risks and ensure the bullet does not exit the woman’s head.

Engaging in a psychological battle with Tess, Jacob taunts her about the dangers of the deeper parts of the cave, including Razor Alley and the Chimney. He describes the horrific fate of a gold miner who died trapped in a similar situation, trying to break her resolve. Despite her fear, Tess remains defiant, holding her knife tightly. She declares that she will make Jacob chase her through the worst part of the cave, known as 'Worse Than Death.'

Detective Washington marvels at the depth and danger of the cave, where Tess endured immense psychological agony. The rescuers found Tess only because they heard her screams echoing through the porous bedrock, thanks to a single distress call sent via a citizens band radio. Surprisingly, the caller was not Jacob but someone else, a detail Washington notes for later. Tess recounts her decision to slide down the Drainpipe to escape Jacob, a risky maneuver that cost her her headlamp but bought her precious time.

At the bottom of the Drainpipe, Tess found herself in Razor Alley, a small, appendix-shaped room filled with helictites—impossible, gravity-defying stone formations. The beauty of the place was overwhelming, and for a moment, Tess felt a connection to Allie, as if her friend was still with her, guiding her. This moment of solace was short-lived as Jacob caught up, and Tess realized she needed to keep moving to survive. She decided to follow Allie’s example and stay ahead of Jacob, navigating the dangerous terrain with renewed determination.

Jacob, upon reaching the bottom of the Drainpipe, was awestruck by the surreal and threatening environment of Razor Alley. The cave formations, resembling worms and alien plants, added to the psychological pressure. He knew he needed to end the chase quickly and aimed to corner Tess at the Chimney, a sheer drop that would trap her. Despite the cave’s hostility, Tess managed to find a single, rusted anchor bolt and attempted to rappel down the Chimney, a last-ditch effort to evade Jacob. The chapter ends with Tess contemplating her options, realizing that she had one more choice: to fight.

Tess’s body weight, accelerated by a plunge into free fall, tightens the rope around Jacob’s right hand with incredible force. The sudden stop caused by the descender locking is brutal, with the carabiner yanking her harness and the straps digging into her flesh, leaving her dangling over the Chimney’s deadly plunge. Despite the pain, Tess feels a sense of satisfaction when she hears Jacob’s agonized screams, knowing that her quick thinking has put him at a disadvantage.

Jacob, however, quickly recovers from the initial shock. He manages to regain control, pinning Tess and disarming her. The struggle is intense, with Jacob using his superior strength to overpower her, and he aims the gun at her face, ready to fire. In a final act of defiance, Tess lets go of the edge, choosing to fall rather than face certain death. Jacob, stunned by her decision, realizes too late that she had deliberately tangled him in her rope during their struggle. The rope snaps taut, trapping him and leaving him vulnerable. The chapter ends with Jacob’s realization of the extent of Tess’s resourcefulness and determination to survive.

Tess’s body weight, accelerated by a plunge into free fall, tightened the rope around Jacob’s right hand with incredible force. The sudden stop caused by the descender locking was brutal, with the carabiner yanking her harness and the straps digging into her flesh, leaving her dangling over the Chimney’s deadly plunge. Despite the pain, Tess felt a sense of satisfaction when she heard Jacob’s agonized screams, knowing that her quick thinking had put him at a disadvantage.

Detective Washington, listening to Tess’s account, is impressed by her resourcefulness and adaptability. She recognizes a stark transformation from the shy, abused introvert who entered the cave to a capable and determined survivor. Tess’s actions were not just about survival; they were driven by a deep-seated need for revenge against the man who murdered her best friend.

Jacob, trapped and in excruciating pain, realized that Tess had used her own weight and momentum to weaponize the rope against him. With his right hand severely injured and the rope acting as a human counterweight, he struggled to breathe. Determined to still get Tess, he used his uninjured hand to draw his combat knife and began sawing through the rope. Tess, sensing the danger, felt the rope go limp and drop past her, leaving her in a precarious position without any backup or safety measures.

Still reeling from the intense struggle, Tess describes to Detective Washington her harrowing experience hanging by her fingertips in the Chimney, a vertical shaft in the Devil’s Staircase cave. The smooth flowstone walls offered no grip, and the darkness and cold water exacerbated her peril. She managed to find a small crack in the rock with her toes, allowing her to rest some of her weight and buy time.

As Jacob, injured but still determined, crawled toward the edge of the ledge above her, ready to shoot, Tess remembered Allie’s encouragement and her own resilience. Visualizing a younger version of Allie urging her to jump, she mustered the courage to let go and fall into the unknown. The chapter captures the intense psychological and physical strain Tess endured, highlighting her transformation from a timid individual to a survivor driven by sisu.

Frustrated and in pain, Jacob realized that Tess had fallen out of his reach. He taunted her, knowing she was trapped in the water below with no means to escape. He vowed to wait, confident that she would eventually succumb to the harsh conditions. The chapter ends with Jacob’s ominous declaration, emphasizing the ongoing threat and the uncertain fate of Tess.

Under increasing pressure from her lieutenant, Detective Washington feels the weight of the investigation's slow progress. The physical evidence from the cave has been compromised, leaving the case to hinge on conflicting statements and unreliable narrators. Washington is particularly frustrated by her own cognitive screening, where she failed to recall all five words given to her.

Returning to Tess’s room, Washington restarts her digital recorder and delves deeper into Tess’s account. She probes for any additional details about Jacob’s motives or affiliations. When asked if she instinctively looked away when Allie was shot, Tess confirms she did. Pressed further, she admits she did not see Allie’s blood or the bullet hole. Washington reveals that Allie’s body has not been found in the Upper Vault, suggesting it might have been moved to one of the nearby lakes.

However, Washington believes Allie’s body is not in the lakes. She hints at a darker, more troubling possibility, which deeply unsettles Tess. The chapter concludes with a brief glimpse of Jacob, who is seen with his girlfriend, discussing whether Tess is dead yet, adding another layer of mystery and tension to the narrative.

In a tense flashback, Allie proposes to Jacob the idea of murdering her best friend, Tess. She outlines a detailed plan, emphasizing the need for secrecy and the importance of staging the crime to make it look like a random attack. Initially reluctant, Jacob is swayed by Allie’s confidence and the promise of a substantial sum of money. The conversation reveals Allie’s manipulative nature and Jacob’s vulnerability to her influence, foreshadowing the tragic events to follow.

Back in the present, Detective Washington interrogates Tess about Allie’s character, probing for any signs of deceit or hidden motives. Tess defends Allie, insisting that she was a genuinely good person and a terrible liar. However, Washington challenges Tess’s perception, suggesting that Allie’s recent behavior, including her trip to Costa Rica and her involvement in a federal investigation, raises suspicions. The detective also points out that Allie took Tess caving without a third person for safety, a violation of basic caving protocols, further questioning Allie’s true intentions.

Washington’s questioning forces Tess to confront the possibility that Allie might have orchestrated the entire situation to frame Tess or eliminate her. The detective’s insights and the mounting evidence create a sense of unease and betrayal, leaving Tess to grapple with the devastating idea that her best friend might have betrayed her in the most extreme way possible.

Jacob reflects on his relationship with Allie, acknowledging her manipulative and complex nature. He describes how she often laments being a bad person, but he reassures her that everyone is flawed. Their conversation delves into the nature of good and bad people, with Jacob arguing that even the most altruistic individuals are driven by self-interest. As the discussion continues, the tension between them grows, reflecting the strain of their deteriorating plan to eliminate Tess. Jacob expresses his frustration and pain from his injured hand, which was damaged during the struggle with Tess. Allie, undeterred, suggests sealing Tess in the cave to starve her to death. However, Jacob points out the impracticality and risks of this plan, including the possibility of other cavers discovering the trap and raising suspicion. Allie, recognizing the need to adapt, proposes a new, more devious strategy: she suggests talking Tess into coming back up the rope, using a fabricated story about surviving the attack. Jacob is skeptical, knowing that Tess is too smart to fall for such a ruse. The tension between them escalates as Jacob reveals that he has lost his gun, which fell into the cave with Tess. This revelation further complicates their situation, leaving them both at a loss for how to proceed. The chapter ends with Allie, still deep in thought, suddenly kissing Jacob and declaring that she knows how to kill Tess. The intimate gesture and her confident assertion add a layer of unpredictability and tension to the narrative.

Trapped at the bottom of the Chimney, Tess faces the imminent threat of hypothermia and the challenge of navigating the dark, wet lower chambers. She manages to find a small space to rest and dry her clothes, but her situation is dire as she has lost her headlamp, knife, and flashlight, leaving her with only emergency glowsticks for light. The chapter delves into the psychological and physical toll of her ordeal, highlighting her resourcefulness and determination to survive.

A pivotal moment occurs when Tess finds Jacob’s gun, a Colt semiautomatic, but her hopes are dashed when she discovers the magazine is empty. Despite this setback, she remains resolute and recalls a detail from Allie’s earlier story about the trapped prospector, realizing there must be a second route to the surface. This realization gives her a new plan to navigate through the infamous 'Worse Than Death' passage to find her way out.

Meanwhile, Detective Washington provides insight into Jacob’s actions, explaining that he had driven to the nearby town of Flour Gold to treat his injuries and gather supplies. The detective reveals that Jacob was captured on security cameras, buying a wrench, heat-resistant tape, and several garden hoses. This information suggests that Jacob had a new plan, potentially involving a method to seal Tess inside the cave permanently.

The chapter concludes with a reflection on the dynamics of the standoff and the unexpected turns in the narrative, as Tess and Washington discuss the implications of Jacob’s actions and the possibility of a second accomplice. Tess’s determination and strategic thinking are highlighted, setting the stage for her next steps in the cave.

Jacob returns to the Devil’s Staircase with a new, sinister plan to kill Tess, devised by his girlfriend, Babygirl. Despite his injured hand, he meticulously prepares to flood the cave with carbon monoxide using his Jeep’s exhaust. Babygirl insists the plan will work, emphasizing the cave’s isolation and the impossibility of Tess escaping the poisonous gas.

Meanwhile, Tess remains trapped at the bottom of the Chimney, desperately searching for a way out. She has lost her headlamp and relies on emergency glowsticks for light. Her attempts to find alternative routes are futile, and she begins to lose hope. A moment of clarity arrives when she throws her glowstick into the water, revealing a tiny black hole in the bedrock—the entrance to Worse Than Death, now submerged. Realizing the passage is underwater, Tess understands the immense danger she faces, as the lower crawlspace is filled with frigid water, making survival nearly impossible.

Detective Washington reflects on the true danger Tess faces, not just from asphyxiation but from carbon monoxide poisoning. She recalls a past case where an elderly man committed suicide by running his truck in a closed garage, resulting in a vivid and horrifying scene of carbon monoxide poisoning. Washington’s experience underscores the lethal nature of Jacob’s plan and the urgency of rescuing Tess before it’s too late.

Jacob, undeterred by his injured hand, meticulously prepares to flood the Devil’s Staircase cave with carbon monoxide. He removes the Jeep’s catalytic converter and wraps loops of adhesive tape around the exhaust manifold, ensuring every seal is airtight and can withstand high temperatures. His girlfriend, Babygirl, insists on her delusional belief that they can still avoid detection, leading to a heated argument over the practicalities of the plan.

Trapped at the bottom of the Chimney, Tess faces a dire situation. She has lost her headlamp and other essential tools, leaving her with only emergency glowsticks for light. The imminent threat of hypothermia and carbon monoxide poisoning looms large. In a moment of clarity, she realizes the gun she found might still have one bullet in the chamber, a critical detail she had forgotten.

Detective Washington, reflecting on the lethal nature of Jacob’s plan, presses Tess during their interview about the resources she had left. Tess’s revelation about the last bullet in the gun gives both her and Washington a glimmer of hope, a crucial factor in her fight for survival.

Tess, still trapped at the bottom of the Chimney, recounts to Detective Washington her desperate attempt to use the last bullet in Jacob’s gun to take him down. Positioning herself at the bottom, she aimed upward, waiting for Jacob to expose himself. However, Jacob, ever cautious and aware of the danger, never showed himself, rendering Tess’s last bullet useless. Despite her efforts to trick him into revealing himself, Jacob remained focused on completing his cleanup. In a critical moment, Tess reveals that she still possesses the original GoPro memory card with footage of Jacob’s face, a piece of evidence that could bring him to justice.

Jacob and Babygirl sit in a tense silence, Babygirl intensely focused on the threat posed by the GoPro camera. They discuss the durability of the camera and the memory card, realizing that if the footage is found, it will implicate them both in the crime. Babygirl insists that they must retrieve the camera, even if it means risking their lives, and suggests a plan to confront Tess together, using her limited ammunition to their advantage.

Meanwhile, Detective Washington and Tess delve into the inconsistencies in Allie’s actions, particularly her decision to bring a camera to a planned murder. Washington suggests that Allie might have been trying to cover her tracks by maintaining the appearance of a normal caving trip. Tess struggles with the idea that Allie could have been so cold and calculating, and Washington pushes her to consider other secrets Allie might have kept, such as involvement in criminal activities. The detective also focuses on Allie’s recent trip to Costa Rica, suggesting that something significant happened there that might be connected to the current situation.

Washington reassures Tess that they will solve the case together, and Tess expresses a sense of unease, as if expecting someone else to enter the hospital room. Washington reveals that her usual partner has retired, and she now sees Tess as a crucial ally in unraveling the mystery.

Jacob stands beside his Jeep, his nerves frayed as he encounters Ethan, Allie’s boyfriend, who is desperately searching for the missing women. Ethan informs Jacob that he found Allie’s car, and Jacob, trying to maintain his cover, claims the cave is closed due to a white-nose syndrome quarantine. Ethan, however, is suspicious and reveals that Allie texted him, saying they were camping at Blue Lake for two nights—a message Jacob knows Babygirl sent as a cover-up.

The situation escalates as Ethan backs away, sensing the danger. Seizing the opportunity, Jacob lunges forward and stabs Ethan in the stomach with his knife. Ethan falls down the hill and lands in the creek, gravely injured. Babygirl, who had been hiding, steps into view and apologizes to Ethan, then restrains him with zip ties, despite his disbelief and pain.

Babygirl, now fully committed to their plan, asserts that they can make Tess give them the GoPro camera. Jacob is skeptical, but Babygirl’s confidence and determination are unsettling. The chapter ends with the two kidnappers now holding a hostage, and the stakes of their situation have dramatically increased.

Still reeling from the shock of Jacob Herman’s death, Tess recounts to Detective Washington a chilling encounter with Jacob, who had dropped Ethan’s glasses down to her, confirming that Allie’s boyfriend was tied up and severely injured on the surface. Jacob demanded that Tess hand over the GoPro camera, threatening to mutilate Ethan and drop pieces of him down to her if she refused. Tess, recognizing Jacob’s desperation and the futility of his threats, knew that giving up the camera would mean certain death for both her and Ethan.

Despite the intense pressure, Tess decided to act on her own terms, rather than trying to emulate Allie’s presumed bravery. She aimed the gun and fired at Jacob as he leaned out to catch the camera, striking a decisive blow. This moment marked a significant shift in Tess’s character, as she chose to assert her own agency and confront the immediate threat, rather than living in Allie’s shadow or making decisions based on what Allie would have done.

Tess’s decision to act independently reflects her growing self-awareness and the realization that she needed to overcome the fictionalized version of Allie she had built in her mind. By taking this action, Tess not only protected herself but also honored Allie’s memory in a way that was true to her own strengths and values.

Jacob Herman’s cause of death was determined to be a single .45-caliber bullet to the throat, nicking his carotid artery. The shot, fired from forty feet below, was not a direct hit but still caused relentless bleeding, leading to Jacob’s death within thirty minutes. Before succumbing to blood loss, Jacob managed to recover the GoPro camera, which contained the damning footage, and staggered back to the surface, where his body was found in his Jeep’s driver’s seat.

Tess reflects on the shot, acknowledging the difficulty and the circumstances under which she fired. Detective Washington praises Tess’s bravery and skill, but Tess remains haunted by the fact that Ethan still bled to death. Washington reassures Tess that she did everything she could and that her survival is a victory. She emphasizes that Tess’s actions were necessary and that she is not disposable.

Washington shares a personal anecdote about a case where a father received a text message confirming his daughter’s death, causing a moment of false hope. Her drive to continue working is fueled by a desire to bring someone back from the dead, to give a family the closure they need. This conversation deepens the bond between Tess and Washington, who sees Tess as a kindred spirit, both underestimated and resilient.

The chapter ends with Washington reflecting on the ongoing investigation and the missing piece of the puzzle: the whereabouts of Allie. She promises Tess that they will find Allie and emphasizes the importance of trusting her gut. Washington also receives a call from an emergency surgeon, who relays disturbing information about Ethan, confirming her suspicions and solidifying her next steps in the investigation.

Night had fallen by the time Jacob staggered back up to the surface, his throat severely wounded by Tess’s bullet. Despite his desperate efforts to staunch the bleeding with a glove and gauze, he knew he was in critical condition. Babygirl, upon seeing Jacob’s state, immediately grasped the gravity of the situation and the futility of their original plan to suffocate Tess in the cave using the Jeep’s exhaust.

Her demeanor shifted from concern to desperation. 'We need to get Jacob to a hospital,' she insisted, her voice trembling. 'We can’t go through with the plan.' The dilemma was stark: they needed the Jeep to save Jacob’s life, but using it to kill Tess was no longer an option. Babygirl’s resolve hardened as she declared she would not go to prison, and she proposed a drastic solution to their predicament.

Jacob, feeling the effects of blood loss and the dizziness of impending death, tried to stand but collapsed. His vision blurred, and he felt a tingling sensation in his toes. Babygirl, with a bleak smile, touched his cheek and then, in a shocking act of betrayal, ripped the bandage off his throat, causing a fatal arterial bleed. Jacob’s last moments were a blur of confusion and horror as he realized Babygirl’s true intentions.

The chapter concludes with a conversation between Detective Washington and her lieutenant. Washington reveals that the second killer was not Ethan or Allie, but Tess herself, who had lied throughout her account. The revelation shakes the foundation of the investigation and sets the stage for a dramatic confrontation.

Detective Layla Washington confronts her lieutenant with the truth about Tess DeWater. She explains that Tess orchestrated Allie’s murder and framed Jacob as the killer. Washington details how Allie fought back, breaking Jacob’s fingers and shooting him in the throat. She emphasizes that Tess’s elaborate lie, designed to make her appear as the hero, was intended to mislead the investigation and ensure that Allie’s body would never be found. The lieutenant remains skeptical, questioning Tess’s motive, but Washington insists that Tess is a master liar and that anyone who underestimates her pays a heavy price.

Washington’s phone call is interrupted by a message from her deputies, who are waiting in the hospital parking lot to take Tess into custody. The lieutenant advises caution, warning that Washington is not at her best and that they should review the audio evidence before making a move. Despite her frustration, Washington reluctantly agrees to let Tess go home, fearing that if they don’t act quickly, she will disappear. The chapter concludes with Washington discovering that Tess has already been discharged from the hospital, setting the stage for a race against time to apprehend her.

Jacob lies in the dirt, his mind racing with the true motive behind Tess’s decision to orchestrate Allie’s murder. Despite their fateful conversation by the Gypsum River, he could only speculate that it wasn’t driven by revenge or jealousy alone. Tess had meticulously planned every detail, from the location and method of the murder to the cover-up, ensuring that she would appear as the sole survivor and hero. However, they had underestimated Allie’s resourcefulness, leading to a botched execution of the plan.

As Jacob lay dying, Tess approached him, intent on securing the final piece of evidence that could implicate him. She found his keys and carefully avoided leaving fingerprints. Jacob, in his delirium, began to laugh uncontrollably, realizing a critical oversight in Tess’s plan. The GoPro memory card, which contained the incriminating footage, was missing. Allie had kept it. This revelation left Tess horrified and desperate, as the missing card could expose her role in the murder. Jacob’s final words, ‘And her video,’ echoed the irony that despite her meticulous planning, Tess’s perfect crime had a fatal flaw.

Twenty stories underground, Allie Merritt swallows the GoPro memory card, cutting her throat and gagging as she holds it down. The memory card, containing incriminating footage, is now inside her, ensuring it won't be found by Tess or the authorities. Her heart races as she reflects on the events that led her to this desperate moment.

In Costa Rica, Allie experienced severe symptoms that she initially dismissed as traveler’s stomach but soon realized she was pregnant. The news thrilled Ethan, but it shattered Allie internally. She envisioned the challenges of balancing her career and travel with motherhood, feeling overwhelmed and anxious about the changes to her identity and lifestyle. Allie had kept her pregnancy a secret, even from Tess, researching it privately and feeling ashamed. She decided to terminate the pregnancy, seeing it as the only way to preserve her life and career.

Now, shivering and alone in the cave, Allie acknowledges her five-week-old pregnancy, comparing it to a sesame seed and reflecting on the irony of her situation. The weight of her decision presses heavily on her, but she knows it is necessary for her survival.

Detective Layla Washington sits in the now-empty hospital room where Tess DeWater was once treated, her mind racing through the final moments at the Devil’s Staircase. The lieutenant, on the phone, listens intently as Washington theorizes about the sequence of events. Washington believes that Allie kept the GoPro memory card, creating a significant dilemma for Tess. With Jacob and Ethan eliminated, Tess had Allie trapped at the bottom of the cave. Starting the engine to flood the cave with carbon monoxide would seal the memory card with Allie’s body, leaving Tess no choice but to descend into the Chimney herself to confront Allie directly. Washington speculates that Tess, an intelligent and cold-blooded individual, would have armed herself with Jacob’s KA-BAR knife and any remaining gear, ready for a hand-to-hand fight. The detective and the lieutenant agree that the final confrontation was inevitable, and whoever won the fight would tell the story. Washington looks at the empty bed, acknowledging that Allie lost, and the real heroine is not who they initially thought.

Trapped at the bottom of the Chimney, Allie prepares for her confrontation with Tess. She listens to the sounds of Tess preparing to descend, feeling a mix of shock, betrayal, and rage. Allie searches for a weapon, finds a rock, and strips off her gear to move more freely. She camouflages herself with mud, concealing her position behind an overhang.

As Tess begins her descent, Allie reflects on her pregnancy, speaking to her unborn child in a detached manner, referring to it as a 'tiny life.' She explains her decision to terminate the pregnancy, acknowledging her lack of maternal instinct and her unwillingness to raise a child. She vows to go through with the abortion if she survives the confrontation. Allie flattens herself against the rock, blending into the cave environment, and waits for Tess to come within striking distance.

However, as the light from Tess’s flashlight approaches, it suddenly retreats, leaving Allie confused. She hears a distant, muffled rumble, realizing that something unexpected is happening. The chapter ends with Allie sensing an unseen threat, adding to the tension and uncertainty of her situation.

Detective Washington stands before her lieutenant, recounting the chilling final moments of Jacob Herman. Even in his dying breath, Jacob managed to crawl to his Jeep and drag himself into the driver’s seat. With his last ounce of strength, he turned the key, starting the engine. The Jeep, idling with a dead man at the wheel, was connected to a long rubber hose that funneled carbon monoxide into the cave. This lethal setup was designed to flood the confined space with poisonous gas, ensuring a slow and agonizing death for both Tess and Allie. Washington explains that Jacob’s final act was a twisted form of revenge, intended to claim the lives of those who had thwarted his plans.

Trapped in the Chimney, Allie and Tess face the thick, toxic fumes from Jacob’s Jeep. Tess panics, clawing at the walls in a desperate attempt to find a way out. Allie, maintaining her composure, instructs Tess to slow her breathing and sit down to conserve oxygen. She proposes a risky plan to escape through the underwater passage known as Worse Than Death, believing it’s their only chance. Tess, still holding Jacob’s knife, is skeptical and warns of the maze-like nature of the tunnels. Allie, determined, asks for the map, but Tess refuses, keeping it as leverage. Reluctantly, Allie accepts the fragile alliance and prepares to dive, clipping an empty water bottle to her wrist as an emergency air reserve. Before submerging, Allie reflects on her past, including a memory of her first date with Ethan. She decides to take the right path, opposite to what Tess suggested, in a desperate bid to find a way out. She reminds herself that death is not to be feared, drawing on a previous near-death experience in Mexico.

Allie finds a narrow cavity in the limestone overhead, providing a small pocket of air. The air is musty and sour, but it is a lifeline. She is barely able to move, feeling like she is crawling through the stomach of a python, with cold water lapping at the ceiling just inches above her. The environment is intensely claustrophobic, and words fail to describe the horror she feels.

Tess catches up to Allie, and Allie accuses her of lying about the direction they should take. Tess denies it, but Allie is skeptical, knowing that Tess’s lies could mean death. The carbon monoxide is still following them through cracks in the rock, and their air supply is dwindling. Allie demands the map, but Tess refuses, describing the upcoming three-way split in the tunnel. Allie, aware of Tess’s manipulative tactics, decides to take the middle route, believing it to be the truth this time.

Allie reflects on her pregnancy, apologizing to her unborn child for her earlier harshness. She acknowledges the danger they are in and promises that no one will kill her child but her. As she swims through the murky water, she encounters artifacts from a failed rescue operation from over a century ago, adding to the sense of isolation and despair. The pressure in her chest builds, and she knows she must make a decision quickly.

Allie and Tess are still trapped in the narrow, flooded tunnel, their air supply dwindling and the threat of carbon monoxide looming. Allie demands the map from Tess, but it is waterlogged and disintegrated, leaving them with only a vague memory of the route. Determined to survive, Allie recalls the map and insists they follow a specific path: down, left, and then up to the surface.

As they crawl through the increasingly tight and unstable tunnel, Allie and Tess are forced to navigate an S-bend, a particularly dangerous section that could easily trap them. The tension escalates as Tess panics and thrashes, risking their lives. Allie, trying to keep them both calm, reveals that Tess’s story about her abusive mother was a lie, and she feels a deep sense of betrayal and regret for not leaving Tess behind sooner.

Allie confesses that she has lied about the map, reversing the directions to ensure Tess takes the wrong path and meets a tragic end. Despite the gravity of the situation, Allie reflects on her love for the world and the beauty of emerging from darkness to light. She also reveals that she has changed her mind about terminating her pregnancy, adding a layer of personal conflict to her actions.

Suddenly, Allie hits a dead end, realizing with horror that Tess must have held the map backward, reversing the directions. Trapped and running out of air, Allie is faced with the grim reality that her plan has backfired, and she is now the one at risk of dying.

Detective Washington reflects on the tragic fate of Allie Merritt, imagining her dying alone in a flooded crawlspace deep within the Devil’s Staircase cave. Despite Allie’s resourcefulness and close calls, the cave’s unforgiving nature ultimately sealed her fate. Washington emphasizes the cruel randomness of survival, where physical positioning and environmental factors determine who lives and who dies.

In the sterile, controlled environment of the Stevens County Sheriff’s Department, Washington and the lieutenant discuss the true roles of those involved in the incident: Jacob, Ethan, and Tess. The lieutenant acknowledges that Tess was indeed the mastermind behind the plan and that they made a critical error by letting her leave the hospital. Washington reveals that she intentionally forgot to call off the deputies stationed downstairs, leading to Tess’s swift arrest as she tried to leave the hospital. The chapter ends with Washington’s satisfaction at outsmarting Tess and ensuring that justice is served.

Seated in a soundproof interrogation room at the Stevens County Sheriff’s Department, Tess DeWater is photographed, fingerprinted, and under intense scrutiny. The room is sterile and controlled, with high-definition cameras and microphones capturing her every move. Detective Washington enters with a smile, acknowledging Tess’s exceptional lying skills and the believability of her earlier account. Washington compliments Tess’s performance but emphasizes that she is now in a controlled environment where the detective holds all the cards.

Washington begins her interrogation by recapping the details of the case, revealing that she has pieced together the true sequence of events. She suspects that Tess was the mastermind behind the plan, using Allie’s identity to commit wire fraud and embezzle money. Washington explains that Tess’s fear of being caught by the feds led her to orchestrate Allie’s murder, framing Jacob as the killer. She describes how Tess’s plan unraveled when Allie fought back and killed Jacob, leaving Tess to improvise and ensure Allie’s body and the GoPro memory card disappeared.

Tess remains silent and composed, but Washington notices the subtle signs of her discomfort and the tension in her muscles. The detective presses on, detailing the psychological and financial pressures that drove Tess to such extremes. Washington’s revelations strip away Tess’s facade, exposing the depths of her deceit and the lengths she went to protect her future. The chapter ends with Washington’s acknowledgment of the hollow nature of solving the case, knowing that it won’t bring Allie back, but she is determined to see justice served.

Trapped underwater in a ten-inch crawlspace, Allie Merritt's lungs burn, and her body is pinned by rocks. Desperation drives her to use an empty water bottle to take one last breath, buying herself a few more seconds of consciousness. She recalls a gap in the ceiling that might contain an air pocket, but her attempts to move backward trigger a collapse, trapping her even more securely.

Disoriented and desperate, Allie realizes that her only chance of escape is to break or dislocate her ankle. The thought is terrifying, but she knows it’s her last option. She positions herself and pushes hard, experiencing excruciating pain, but the bone doesn’t break. Her repeated attempts only maul her ankle, and she loses consciousness, apologizing to her unborn child in her final moments.

Detective Washington reflects on the emotional impact of a past case, where a father received a false message about his daughter’s survival, only to lose her again. The memory resonates with her as she contemplates the irreversible nature of Allie’s fate in the Devil’s Staircase cave.

In a sterile, soundproof room, Tess DeWater remains composed under intense scrutiny, repeatedly asserting her innocence and playing the role of a traumatized survivor. Washington is both impressed and frustrated by Tess’s cunning and resilience, recognizing her ability to manipulate and deceive. Tess’s legal knowledge and experience as a law student make her a formidable opponent, and she begins to challenge the legality of her arrest, questioning the probable cause and the evidence against her.

Tess’s confidence grows as she perceives Washington’s vulnerability. She plays dumb, referencing legal procedures and the consequences of an unlawful arrest, subtly suggesting that Washington has overstepped. Washington remains silent, aware that Tess is testing the limits of her authority. Tess’s microscopic smile reveals her belief that she can still slip away, despite the detective’s efforts to break her.

Allie and Ethan reminisce about their first date at a cemetery, where they discussed the concept of safety coffins with bells to alert passersby if someone was buried alive. Allie, reflecting on the romantic and isolating aspects of being a public figure, shares her thoughts on motherhood, revealing her insecurities about being a good mother. Ethan, however, reassures her, sharing a story from their first meeting where she calmly handled a scorpion, which he saw as a sign of her character.

Underwater in the cave, Allie's mind races with memories of Ethan’s words about her being an amazing mother. Her thoughts give her the strength to find a small pocket of air trapped in the tunnel’s highest crease. With her last bit of strength, she sucks in the final breath of oxygen, then braces herself against her trapped ankle, determined to break free or die trying.

Washington reflects on Tess’s meticulous planning, imagining her cleaning up the crime scene after midnight, ensuring no trace of her involvement remained. The detective leans back in her chair, relaxing her tensed muscles, and addresses Tess directly. She concedes that if they had arrested Tess without probable cause, it would have been a significant legal error, potentially costing Washington her job. However, she points out that Tess never considered the alternative. Tess’s feigned confidence wavers, and a shade of doubt creeps into her voice as she admits she doesn’t understand. Washington suggests revisiting the events of that day, implying that there is more to the story than Tess has accounted for. The detective’s calm demeanor and strategic questioning begin to chip away at Tess’s facade, hinting at a deeper, more complex truth.

Severely injured and zip-tied, Ethan continues to grind his wrists against the rock, the white-hot pain keeping him tethered to consciousness. After hours, he senses the restraints are about to snap and hears soft footsteps approaching—Tess. She circles the area, wiping surfaces and moving things around, confirming her crime scene is clean. Ethan remains still, pretending to be unconscious, and uses a technique to hide his pulse, fooling Tess into thinking he is dead.

Once Tess leaves, Ethan frees himself and tears an eyehole in the fabric bag. He crawls toward the Jeep, enduring excruciating pain, and manages to reach the dashboard radio. He sends a distress call, leading to his eventual rescue and emergency surgery.

During the interrogation, Detective Washington reveals the ongoing rescue effort to save Allie, who has been fighting for her life and that of her unborn child. The detective’s strategic withholding of information has allowed her to manipulate Tess, who is now realizing the full extent of her mistakes. Tess is visibly shaken by the news, her composure crumbling. She finally breaks, requesting a lawyer. Washington, satisfied with the information she has obtained, leaves the room, feeling a sense of relief and the crisp air of the outside world. She reflects on the resilience and sisu of the survivors, emphasizing the theme of perseverance in the face of adversity.

Ethan wakes up in a hospital room, intubated and surrounded by medical equipment. His vision and thoughts are clouded by anesthesia, making it difficult to focus. A shadow by the window greets him, and he recognizes Detective Layla Washington. She explains that she is there to inform him about his condition and the ongoing investigation, reassuring him that he has undergone major surgery and is recovering. Despite his inability to speak, Ethan tries to mouth Allie’s name, indicating his concern for her. Washington smiles warmly and reveals that she has something to show him, leaning in to display her phone. The text message chain is initially blurry, but Ethan manages to focus on the last message, which reads, 'WE SAVED HER.' The news brings a profound sense of relief and disbelief, as Ethan realizes that Allie has been rescued and is alive.
