The Unknown Summary Chapter by Chapter

⚠️ Spoiler Warning: This section contains detailed, chapter-by-chapter plot summaries. Every major event from the novel is revealed below.

Prologue: June 15, 1926—9 p.m. (Daisy Rue Diary)

A terrified narrator writes as a storm rages outside her thin cottage walls on New Avalon island. She describes “The Darkness” as a vile, seething entity with a palpable presence that has already claimed the lives of everyone else staying on the island.

Only two people remain alive, and the narrator is certain she will suffer the same fate soon. She once believed she was responsible for summoning this force but now understands the evil existed on the island long before her arrival.

She prepares for one final attempt to banish the Darkness, though she is plagued by the fear that this effort will end in failure. The entry closes with her contemplating her own imminent death.

Chapter 1: The Arrival

Marin Keane, an unknown actress, arrives at Lake Faraday and sees New Avalon as a dark smudge on the horizon. Producer Loretta Zeverin greets her at the dock in sharp Hollywood attire while Marin feels like a nervous child on her first day of school.

She recalls her audition with the acclaimed director Ronan Peters, who asked her to tell a ghost story instead of reading lines. Marin shared a personal tale about seeing her dead sister’s ghost, a moment that won her the role.

She replaces an actress named Lindy Garrett and will earn $100,000 for six weeks of work. As the boat departs, Marin receives an anonymous text from “the woman you replaced,” delivering an ominous warning.

Chapter 2: Setting Foot on Avalon

The boat approaches New Avalon, which appears larger and wilder than expected—two miles from the mainland with a dense forest plateau and sharp northern cliff. Loretta dismisses Marin’s concerns about the island’s dark history as mere “summer camp” enthusiasm.

Marin receives a second warning text from Lindy Garrett, claiming she will regret setting foot on the island. Pete, the boat driver, watches her hesitation without offering reassurance.

Loretta makes Marin sign a strict NDA and risk waiver before stepping onto the dock. The island has no electricity, and production assistant Brad Brillstein leads her past four identical cottages and a Victorian house with a massive, lightning-split oak tree at the center of the green—the same tree where dresses were found in 1926.

Chapter 3: The Table Read

Brad escorts Marin to the Victorian main house for the first table read, where she notices a hex sign carved into the stone foundation. Inside, she meets her castmates: Julianne Brown, Heather Benchley, and Susie Hutchinson, who immediately recognizes Marin from an eczema drug commercial.

Legendary actress Violet Wright enters and commands total attention with her incandescent presence. Brad confiscates everyone’s cell phones to enforce the 1926 lifestyle, explaining only he and Loretta have solar-powered phones for emergencies.

Ronan distributes the scripts titled Darkness, and Marin is shocked to discover Daisy Rue is the main character—meaning she, a complete unknown, has been cast as the lead of the film.

Diary: June 6, 1926

Daisy Rue introduces herself and explains Mrs. Semple gave her a diary to record her story, believing fate brought them together because of Daisy’s “Gift”—the ability to hear the dead. Her father recently passed away, leaving her in a boardinghouse before Mrs. Semple offered sanctuary.

Upon reaching New Avalon, Daisy feels an unsettled aura of foreboding but immediately loves her cottage. She meets the other guests: haughty Katrina Fiske, bold Jonquil Collins, and maternal Mrs. Minafer, who reminds Daisy of her own mother.

Daisy asks if the other women also have gifts. Jonquil jokes her “gams” are her only gift, while Katrina acts suspiciously. Despite her misgivings, Daisy decides she loves New Avalon and feels at home.

Chapter 4: The Wall of Symbols

Marin stands in the woods trying to “become” Daisy but finds her own thoughts too intrusive. She overhears Susie telling Heather that a “nobody” getting the lead is unfair, suggesting Marin slept with Ronan to secure the part.

Hurt and angry, Marin confronts Ronan about Lindy Garrett’s departure. He claims Lindy was “deranged” in her audition and gives Marin a transcript of Daisy Rue’s actual diary from the Vermont History Museum.

Marin spots Loretta and Violet whispering in a hallway and learns Lindy was fired because she was too terrified to come to the island. Lindy’s final warning to Loretta was that none of them would leave New Avalon alive.

Diary: June 7, 1926

Daisy notices Mrs. Semple constantly watching the women from a distance. She goes for a walk in the woods with Jonquil and Katrina, and they discover more daisy wheels carved into the trees, forming a wall of symbols around the island.

They find a clearing with crimson moss and a large stone slab resembling an altar. Mrs. Semple suddenly appears and explains the stone is a remnant from previous inhabitants rumored to be witches.

She reveals her father, Roderick, carved the hexafoils to ward off ghosts of men killed by his cannons before descending into madness. The clearing unsettles Daisy, and Mrs. Minafer mutters it is an “unholy space.”

Chapter 5: The Script vs. The Reality

Night falls and Marin finds the island darkness all-encompassing. She reads the diary transcript again and realizes Ronan’s script is a shockingly faithful adaptation, following the order of disappearances exactly.

A soft, persistent scratching sound emanates from the walls or floor of her cottage. Investigating, she discovers a daisy wheel carved into the baseboard—the same one Daisy mentioned carving in her diary.

Marin feels a connection to Daisy, both being guileless newcomers. The scratching stops as abruptly as it started, and though she remains skeptical of the supernatural, the diary’s missing pages feel like an eternal cliffhanger.

Diary: June 8, 1926

Daisy reports little of note happening on the island. The women wade in the lake, and Katrina reveals her gift: visions of the future. Mrs. Minafer explains she is an empath who senses others’ moods, while Daisy shares she hears the dead.

Katrina experiences a sudden vision and claims she saw “Darkness personified” outside Daisy’s cottage door. Though she laughs it off as a prank, Daisy sees real fear in her eyes.

Jonquil remains the group’s official skeptic, believing all the supernatural talk to be “bunk.” Daisy still trusts the voices she hears are real and continues searching for a place to call home after her father’s death.

Chapter 6: A Martini with a Legend

Marin cooks a meal for the cast using era-appropriate food in the main house’s antique kitchen. Susie complains about the lack of catering, and the actresses discuss whether they have heard scratching noises in their cottages.

Violet Wright visits Marin’s cottage later with a thermos of strong gin martinis and shows her a locket containing a picture of her beautiful daughter. She admits she took the role partly because her sister Loretta wanted her to do it.

Violet reveals a childhood obsession with the New Avalon story and briefly slips into character as Ruth Hume Semple, terrifying Marin with a cold, intense stare. Ronan knocks on the door to announce the start of a séance.

Diary: June 9, 1926

Daisy returns to her cottage to find Mrs. Semple searching through her suitcase and diary, claiming she was looking for a lost hairbrush. Mrs. Semple then suggests they hold a séance.

The group gathers in the parlor as a storm approaches, using a glass and wooden letter tiles. A spirit named “Azra” identifies itself but claims not to be a spirit. The glass spells “LET ME OUT” repeatedly, and a ragged voice whispers to Daisy: “You will be last.”

Lightning strikes the great oak tree outside, splitting it in two and ending the session. Mrs. Minafer declares that “Hell has broken loose,” and Daisy fears Azra is still present on the island.

Chapter 7: The First Trick

The modern cast gathers for a séance in the dark parlor lit only by candles. Brad creates a makeshift spirit board with paper squares while Ronan and Loretta watch from a dark corner.

Marin leads the session and feels the glass move slightly before a chair suddenly slides across the room on its own. She catches the fishing line tied to the chair and Brad’s ankle, exposing the trick.

Ronan admits he and Brad used mechanical tricks to make the experience feel authentic for the actors, including fake footprints and scratching noises. Loretta insists they continue the séance to see what happens when it is “real.”

Chapter 8: The Séance Becomes Real

The group resumes, and a display of framed butterflies falls off the wall and shatters. The glass moves to “YES” and identifies the spirit as Azra, spelling “LEAVE NOW” before revealing names only individuals would know.

It spells “CLARENCE CEDRIC,” Heather’s cousin; “DEAN,” Julianne’s first husband; “FRANK,” Violet’s father; and “MOLLY,” Marin’s dead sister. Ronan stops the session when “ELISE” is spelled, becoming visibly angry.

The table begins to hop on its own, all candles extinguish at once, and a voice whispers to Marin: “You will be last.” Brad collapses in agony, and Loretta takes him to the mainland in the only boat, leaving the cast stranded without phones.

Diary: June 10, 1926

Daisy wakes feeling groggy and discovers someone wrote “I AM OUT” in her diary in childlike handwriting. She suspects Katrina is playing pranks and prepares to confront her.

Mrs. Semple invites Daisy for a walk and sketches a remarkably accurate portrait of her before they reach the cliff and spot their boat adrift in the lake. They rush to the dock and find the rope has come loose or been untied.

Daisy asks when the next visitor will arrive, and Mrs. Semple says not for another week. The group realizes they are trapped at the mercy of the island with no one else present to have untied the boat.

Chapter 9: Stranded Without Phones

Marin lies awake in the sweltering darkness, hearing the scratching noise again. She tells the noise “if you’re Molly… please be gone,” and the scratching stops, leaving her reflecting on being trapped with no boat, electricity, or phones.

At dawn, she finds Violet already cooking breakfast. Julianne joins them and admits feeling like someone was lurking in her cottage. Heather arrives claiming she slept like the dead, and Violet accidentally burns her finger on the stove.

Julianne suggests Azra wanted Brad out of the way. Marin remains skeptical but is deeply unsettled by the séance’s accuracy regarding personal names. Violet insists Loretta will return by lunchtime, but suppressed panic hangs over the group.

Diary: June 10, 1926—Later

Mrs. Semple retreats to her bedroom acting strangely and misses dinner. Daisy brings her a plate and accidentally reads a journal entry on her desk that says, “Dear God, what have I caused? … we’ve opened a Pandora’s box.”

In the kitchen, Jonquil accuses one of them of untying the boat. Katrina implies Daisy did it to keep Mrs. Semple’s attention, while Daisy retorts that Katrina snuck into her room to move her belongings.

Mrs. Minafer snaps at both of them, declaring it was “the work of Azra.” Daisy loses her appetite and wonders if she truly possesses more power than she realized. The atmosphere among the women turns increasingly hostile.

Chapter 10: A Message on the Table

Marin investigates the séance room in the morning light and finds the fishing line and Brad’s other tricks still present. Crawling under the table, she finds no hidden mechanisms that could have made it hop.

She discovers nine letters remaining on the table that spell “YOURE LAST.” Susie appears and tells Marin she heard a voice say “You will be first,” admitting she hates Marin because she “doesn’t belong here” and hasn’t “paid her dues.”

Susie’s voice is meek and frightened despite her mean-girl persona. Marin scrambles the letters so Susie won’t see the message, realizing they both heard different warnings from the voice, establishing a specific order.

Chapter 11: The Flesh Wound

The group rehearses the cliff scene where Mrs. Semple sketches Daisy. Marin struggles with her performance next to the effortless Violet Wright but eventually manages a perfect take by channeling Daisy’s fear and fascination.

After Violet leaves, Ronan tells Marin that “ELISE” was an aspiring actress who died two years ago, and he overreacted because her name was such a shock. He swears he is no longer playing tricks on the cast.

Marin trips and scrapes her knee, and Ronan strips off his shirt to clean the wound, revealing a muscular physique she finds attractive. He carries her back to her cottage, a moment Susie witnesses from her porch.

Chapter 12: A Shadow at the Window

Marin watches from her window as Ronan enters Susie’s cottage at 11 p.m., feeling a mix of hurt, anger, and disappointment. She assumes Susie is trying to “steal” her role through seduction.

Later that night, a loud thwump sound awakens Marin, and she sees a shadow at her window that looks like her dead sister Molly, dripping wet. She repeats her childhood mantra: “You’re not real. You don’t exist. Please be gone.”

When she finally gathers the courage to check the porch, the spot where the shadow stood is inexplicably and terrifyingly wet. Marin begins to doubt her own sanity as exhaustion and isolation take their toll.

Diary: June ?, 1926

Daisy has a terrible nightmare in which she follows a cloaked figure—Azra—through the woods to the crimson moss clearing. She sees Katrina sleeping on the stone altar, and Azra draws a sharp knife, raising it as Katrina screams.

Daisy wakes from the dream and finds mud and dirt on the floor leading to her bed. Her boots are caked with mud and pine needles, horrifying her with the possibility that she was actually in the woods during the night.

She realizes the nightmare might not have been a dream at all. The date is uncertain because she is losing track of time, and she feels as though she is being bewitched by the figure from her visions.

Chapter 13: The First Dress

Marin wakes after fitful sleep and tries convincing herself the Molly sighting was a dream. Walking toward the kitchen, she stops at the oak tree and discovers clothes hanging high in the branches—a cream top and maroon skirt with satin trim.

She recognizes the outfit as Susie Hutchinson’s costume and recalls the séance whisper: “You will be first.” Marin runs to Susie’s cottage and finds it completely empty.

The discovery mirrors the historical account of the 1926 disappearances exactly. Marin’s mouth goes dry with terror as she realizes the sequence of events is repeating precisely as it did for Daisy Rue. The clothes are too high to have been hung without a ladder.

Diary: June 11, 1926

Daisy discovers Katrina is missing and finds her clothes in the oak tree. She remembers her nightmare about Azra and believes Katrina was the real target of the cloaked figure, not just a dream image.

Jonquil checks Katrina’s cottage and confirms she is gone. Daisy tells the others about her dream and suggests searching the clearing with the stone altar, but Mrs. Minafer warns the woods might be dangerous.

Jonquil is determined to search, refusing to accept the idea of simply waiting to be taken. Daisy recalls Azra’s voice telling her she would be “last” and prays her nightmare of the murder was not real as they set off into the woods.

Chapter 14: Finding the Camcorder

Heather threatens Ronan, thinking Susie’s disappearance is another trick. Ronan swears he had nothing to do with it. They search Susie’s cottage and find her wallet, vape, and a spare battery.

Marin reveals she saw Ronan enter Susie’s cottage the previous night. He admits he was there but claims he left because Susie tried to seduce him and it got “uncomfortable.”

The group pairs off to search the island. Marin and Violet head toward the cliff and find the circular clearing with brown moss and the flat stone altar. On top of the rock sits a digital camcorder, which Marin opens and presses play.

Chapter 15: The Tape Evidence

The cast watches the video in the parlor. The first recording shows Susie setting up the camera to record her attempted seduction of Ronan, capturing him rejecting her and threatening to fire her. Ronan is relieved the tape proves his innocence.

Violet finds a second video showing Susie in the woods at night, terrified and lost, filming herself. She says she followed “something” outside her cottage, and the camera captures a suspicious crunch in the brush.

Susie enters the clearing, shouts “Who’s there?”, and a dark blur rushes at her. The camera somersaults, and the recording ends after a cut-off scream. The cast sits in stunned silence, realizing something terrible has happened.

Diary: June 11, 1926—Later

Daisy and Jonquil find the clearing, but the stone slab is clean of blood. Relieved, Daisy thinks it was just a nightmare—until they discover a freshly dug rectangular hole nearby containing a wooden box she fears is a coffin.

Inside the crate, they find bootlegged liquor instead of a body. Mrs. Semple arrives and explains New Avalon is a way station for bootleggers, admitting she takes bribes to allow them to store liquor on the island.

The bootleggers use a secret inlet on the west side of the island. Daisy wonders if Katrina left with them, but Mrs. Semple says the crate was already there. They find no other trace of Katrina, and Daisy remains convinced Azra took her.

Chapter 16: Suspecting Pete

The modern cast votes to leave immediately, but they have no boat. Ronan offers to swim the two miles, but the group decides it is too risky. Marin retrieves the diary transcript and notes that “Mr. Ruggle”—Pete’s grandfather—was mentioned in connection with bootleggers.

She suggests Pete might be the person in Susie’s video, trying to protect his family’s legacy. Julianne believes history is repeating itself and that Azra has returned, while Marin proposes a former cast member is acting out the script to derail production.

Ronan provides a headshot of Lindy Garrett, and Marin is shocked to recognize her as the woman she saw watching her at the dock. Lindy was physically present in Vermont and might be on the island.

Chapter 17: The Suspect List

Night falls again, and Marin is too anxious to sleep. She writes a list of suspects: Pete, Molly, Azra, Ronan, and Lindy. Scratching resumes in the cottage walls as she writes “Azra.”

Ronan pulls Marin aside to reveal Loretta insisted on coming to the island despite his objections. He asks if Marin believes he is innocent, and she notes he seems sincere but could still be a “method” trickster.

Violet reveals she was the one who found Lindy “unimpressive” and “awkward,” leading to her firing. Marin chooses to sleep in her cottage but locks the door and props a chair against it. She is awakened by a thwump and sees Molly at the window again before noticing someone lurking in Susie’s supposedly empty cottage.

Diary: June 12, 1926

Daisy finds “GO AWAY DAISY” written in her diary in childlike scrawl. Mrs. Minafer suggests Daisy is sleepwalking, but Daisy doubts this explanation.

Mrs. Semple suggests another séance to determine if Katrina is dead. They gather in the parlor, and Daisy falls into a trance lasting thirteen minutes. When she wakes, the others tell her Azra spoke through the glass.

Azra said “HELLO DAISY” and promised they would see her again soon, adding that another person would soon be gone. Daisy is terrified, dizzy, and unable to remember the trance. She suspects someone has been moving her belongings.

Chapter 18: S-O-S Signaling

Marin enters Susie’s cottage armed with a plunger and finds Heather inside, searching for a flashlight to signal for help using Morse code. They go to the lake shore, and Heather signals “S-O-S” toward the mainland.

Marin walks to the dock for a better view of potential boats. She watches Heather’s light blinking in the distance when suddenly the blinking stops, and the flashlight falls to the ground, its beam steady.

Marin runs back and finds the flashlight, but Heather is gone with no signs of a struggle. She returns to the village and finds Heather’s polka-dot dress hanging in the oak tree, breathless and hysterical. The silence of the lake is eerie.

Diary: June 13, 1926

Jonquil disappears, and Daisy finds her dress in the tree. Daisy has a vivid nightmare about Azra murdering Jonquil at the altar, slitting her throat while Daisy hears the “slick gurgle of blood.”

Daisy wakes up screaming a word she eventually remembers is “Daddy.” She realized she saw her father’s face when Azra pulled down their hood. The memory of the wet slap of the body haunts her.

She is certain all the supernatural events are related to her past and organizes a search for Jonquil, though she fears it is useless. Daisy realizes the nightmares were real events, and her father was an abusive drunk whose death she had previously blocked from memory.

Chapter 19: Admitting the Haunting

Marin screams, and the others join her at the oak tree to see Heather’s dress. She explains Heather vanished in a matter of seconds while signaling for help. Julianne insists they have summoned Azra and that history is repeating itself.

Julianne claims Azra thinks they are the 1926 women because they are dressed and acting like them. Violet and Julianne admit they have also felt a familiar presence—Julianne sensed her first husband Dean, and Violet smelled her father’s pipe smoke.

Marin admits she has seen her sister Molly’s ghost at her window. Ronan remains skeptical, but the women are convinced they are being targeted personally. Julianne quotes the Bible, calling Azra a “demon” using their dead loved ones to lure them.

Chapter 20: The Backstory of Molly

Marin recounts her full history with Molly, which she had mostly lied about in her audition. Molly was eleven and Marin was four when Molly drowned in an above-ground pool. Marin was home when it happened but was too busy “pretending” to go outside and check on her.

She believes Molly’s ghost haunted her window for a year to remind her of her guilt. Julianne reveals she felt guilty because she asked for a divorce an hour before Dean was killed by a cab, and Violet reveals she chose a movie role over visiting her dying father.

Marin suggests the island is “receptive” to hauntings and everyone brought their own ghosts. They conclude Azra is using these ghosts to isolate them, while Ronan is horrified by their “crazy” talk.

Diary: June 13, 1926—Later

Jonquil is confirmed gone after a thorough search of the island. Daisy tells Mrs. Semple about her nightmare and seeing her father’s face. Mrs. Semple suggests Azra peered into Daisy’s thoughts and made her father’s image manifest.

Daisy weeps on Mrs. Semple’s shoulder at the clearing. Mrs. Minafer asks Daisy if she is a “proper Christian” to protect herself from evil, referring to Azra as “The Darkness.”

Daisy sneaks into the main house, steals a sharp knife from the kitchen, and returns to her cottage to carve another daisy wheel into the wall. She watches the dresses in the tree, calling them “dress-shaped gravestones,” and fears she accidentally set the Darkness free.

Chapter 21: Julianne’s Disappearance

The remaining cast members sleep in the main house for safety. Marin shares a room with Julianne, and they pray together. Julianne explains that demons “provoke people into sinning” and “deceive.”

Marin lies awake, fearing Molly is outside the window. She drifts into a short sleep and wakes to find Julianne at the window, claiming she sees Dean outside by the oak tree and that he wants her to come out.

Marin tries to stop her, but Julianne is hypnotized and then becomes hysterical, shoving Marin against the wall before running into the mist. When Marin returns to the oak tree, Julianne’s dress is already hanging in the branches.

Diary: June 14, 1926

Phoebe Minafer vanishes during the night, leaving Daisy and Mrs. Semple as the last survivors. Daisy finds Mrs. Minafer’s dress in the tree after waking from a long sleep and feels a shameful sense of relief that she was not the one taken.

She credits her carved daisy wheel with protecting her. Daisy and Mrs. Semple search the island but find nothing. Daisy fears that if they don’t act soon, Mrs. Semple will be claimed next.

The tone is one of absolute resignation and terror. Daisy notes she slept for hours while Phoebe disappeared, and she feels guilty for her relief. She believes she is being saved for last, exactly as the whisper predicted.

Chapter 22: Breaking the Pattern

Marin sits in the parlor frantically reading Daisy’s diary for clues to stop the cycle. She notes Daisy, Jonquil, and Phoebe were taken in the same order as the modern actresses. Violet’s palm is cold as a corpse.

Marin realizes Julianne’s dress ended up in the tree in less than a minute, and she wonders if Azra disintegrates people, leaving only their clothes. Ronan admits he has also sensed a presence: the perfume of his dead girlfriend, Elise.

Violet suggests they make peace with their ghosts to break Azra’s ammunition and proposes one last séance to confront their pasts. Marin feels a haunted, hollow feeling as the group prepares for what comes next.

Diary: June 14, 1926—Night

Daisy is now staying in the main house, too scared to be alone in the cottages. She hears Mrs. Semple bustling in her room and admires her bravery while feeling intense guilt, believing she “set the Darkness free” during the first séance.

Mrs. Semple finds Daisy weeping and suggests they ask the Darkness what it wants. Daisy is terrified of what it might say but eventually agrees to a final séance. She prays she will not die before she wakes.

She wonders why the Darkness addressed her specifically. Mrs. Semple tells her that “Azra” can mean “light,” suggesting a purpose behind the terror. Daisy scribbles her thoughts before it’s too late, no longer trusting Mrs. Semple’s calmness.

Chapter 23: The Hallway Kiss

Marin decides to delay the séance until the next night so everyone can rest. She finds Julianne’s nightgown on the floor and feels overwhelming guilt before heading to the parlor to retrieve the diary.

In the hallway, she meets Ronan, who is half-naked in his boxers and seems to mistake Marin for Elise. He tries to kiss her and suggests they sleep in his bed together. Marin rejects him and flees to her room, feeling violated.

She later sneaks into Violet’s room to talk about what happened and finds it empty but discovers an old flip phone in Violet’s suitcase, alongside books on hexology, witchcraft, and demonology. Violet has had a phone the entire time.

Diary: June 15, 1926—10 p.m.

Daisy is terrified of the upcoming séance and tries to back out. Mrs. Semple tells her the name “Azra” can mean “light” and insists there is a purpose for everything happening on the island.

Daisy realizes she no longer trusts Mrs. Semple, who has been too calm throughout the disappearances. She wonders if Mrs. Semple knew what would happen and brought them to New Avalon for a specific, sinister reason.

Mrs. Semple knocks on Daisy’s door, insistent that they begin. A storm rages outside, making escape impossible, and Daisy feels like a prisoner heading to the gallows, worrying the Darkness is already waiting in the shadows.

Chapter 24: The Secret Flip Phone

Marin confronts Violet about the flip phone, but Violet claims it has a dead battery. Marin accuses Violet and Loretta of wanting to be stranded to find out “what really happened” on the island and suggests they made Brad sick on purpose.

Violet is indignant and claims she cares about what happens to women. When Marin asks if they did something to Susie, Heather, and Julianne, Violet says, “They might not be as lost as you think,” with a coy smile.

She refuses to confess and tells Marin “no comment” when asked to prove she isn’t behind the vanishings. Marin notices books on spells and witchcraft on the bed, deepening her suspicion.

Diary: June 15, 1926—11 p.m.

The final séance begins, and Daisy senses the Darkness present without being summoned. The Darkness emerges and looks exactly like Daisy’s abusive father. Mrs. Semple claims she cannot see him and smiles, confirming Daisy’s worst fears.

Daisy realizes Mrs. Semple has been working together with Azra all along. Mrs. Semple calls herself a “woman with wisdom” like the women of Avalon. The shadows fill the room, and the father-figure’s face shifts into a terrifying visage.

Daisy overturns the table and flees to her cottage, barricading herself inside. She hears scratching and then tapping on the window. She screams for the Darkness to leave, but it continues tapping, and she finally decides to look out to see who is there.

Chapter 25: The Reveal of the Living

Marin returns to her cottage and waits in bed with Heather’s flashlight. The scratching and thwumps return, and she sees a shadow at her window. She shines the light on it and discovers it is not Molly but Susie Hutchinson, looking wet and hissing.

Marin chases Susie through the woods and tackles her. Heather and Julianne emerge from the mist and restrain Marin, telling her she “wasn’t supposed to find out.” Susie sneers that Marin “ruined it.”

Violet appears, descending from the hill like a cult leader, and decides to tell Marin the truth. Marin realizes the “Molly” she saw at her window was just a soaking wet Susie in disguise the entire time.

Chapter 26: The Elise Haines Motive

Violet reveals every supernatural event was fake, staged with help from Brad and Loretta. Heather “vanished” by hiding in a camouflage sleeping bag under a downed tree, and the clothes were hung in the oak tree using a pole and hook.

The hauntings were all intended to scare Ronan into confessing that he filmed Elise Haines having sex without her consent and shared the video with friends. Elise was their friend, and they wanted Ronan to pay for driving her to suicide.

They admit they used Marin’s trauma about Molly to make the haunting more believable to Ronan. Marin is furious at being exploited and used, and Violet asks her to help with the final séance to get Ronan’s confession on tape. Marin refuses to comment and storms back to her cottage.

Diary: June 16, 1926 (The Lost Pages)

Daisy realizes the Darkness wearing her face means she was the killer all along. Mrs. Semple explains that Daisy has been “possessed” by her alternate personality, Azra, and Daisy begins recalling the physical and sexual abuse she suffered from her father.

She remembers murdering her father with a knife. Mrs. Semple had been observing her and recording her “afflictions of the mind” as part of a psychological study.

Daisy panics and stabs Mrs. Semple to death in the cottage, burying her body under the floorboards. She hangs Mrs. Semple’s dress and her own in the tree as a memorial before deciding to “head for the light” to join her mother, feeling no more fear or sadness.

Chapter 27: Kicking the Baseboard

Marin finds the lost diary pages by kicking and ripping out the cottage baseboard in a fit of rage. She reads that Daisy was the true killer and that Mrs. Semple is buried beneath the cottage floor.

Marin shows the pages to Violet and Ronan but doesn’t reveal she destroyed the wall. Ronan calls Daisy a “psychopath,” while Violet argues she was a “damaged” victim. The missing pages disrupt Violet’s plan because they provide a logical explanation for the 1926 deaths.

Despite this, Ronan agrees to the séance to appease the “scared” women. Marin privately tells Violet she is “in” on the plan to get Ronan, setting the final trap in motion.

Chapter 28: The Decision to Proceed

Marin and Violet prepare the parlor for the final trap. Violet explains Brad rigged the candles and the table to move, and Marin finds the hidden camcorder inside a mahogany box. Violet tells Marin she needs to “sell” the performance of contacting Molly.

Marin notices the scratching and thwumps in her cottage continue even when no one else is there, making her start to believe the cottage is actually haunted. She wonders if Daisy’s “Azra” was a real possession after all.

She carves a daisy wheel into the sideboard using an ice pick “just in case” and feels a haunted, hollow feeling. She realizes Ronan has learned nothing and is still eyeing her as a target, confirming his predatory nature.

Chapter 29: Finding the Skeleton

Marin investigates a specific floorboard after a massive thwump rattles the rafters. She pries up the boards and finds a dark, rotting chasm containing a human skeleton with long white hair, still clutching a leather-bound journal.

Marin realizes the thumping was Mrs. Semple’s ghost trying to show her the truth. The journal reveals Mrs. Semple was a pioneer in psychology who brought a patient named “Azra Kovacic” to the island to treat her for paranoid schizophrenia and multiple personality disorder.

Mrs. Semple confirms that Katrina, Jonquil, and Mrs. Minafer were merely Daisy’s hallucinations. Daisy Rue was just one of Azra’s personalities, meaning the “missing women” of 1926 never actually existed outside Azra’s mind.

Chapter 30: The Final Séance

The final séance begins with Marin, Violet, and Ronan. Marin successfully fakes a trance, and the glass spells “DAISY.” Suddenly, Violet’s demeanor changes entirely—she slumps over, vomits, and when she looks up, she claims her name is “Daisy.”

Marin is unsure if Violet is acting or truly possessed. Violet-as-Daisy gives Ronan a flirty wave and claims she doesn’t know where she is. Marin tells Ronan the haunting was a fake designed to get his confession.

Panicked and confused, Ronan admits he filmed sex tapes with “seven or eight” women, including Elise, calling it “harmless fun” and claiming it wasn’t his fault Elise “overreacted.” The confession is captured on camera.

Chapter 31: The Stabbing

Violet-as-Daisy leaps from her chair with superhuman speed and grabs the ice pick, holding it to Ronan’s neck. He screams for Marin to help him as Violet forces him to state specifically what he did to Elise.

Violet-as-Daisy claims she “hurt people, too” and that her father hurt her. Suddenly, she lunges and stabs Ronan repeatedly in the stomach. He dies on the floor in a torrent of blood.

Violet then “wakes up” and screams at the sight of her bloody hands, claiming she can’t remember anything. Marin checks for a pulse and finds none, realizing the séance has ended in actual murder.

Chapter 32: The Cover-Up

Marin realizes no one will believe Violet was possessed and that they will both be charged with murder. They decide to cover up the crime by throwing Ronan’s body off the cliff, cleaning the parlor, and burning their bloody dresses.

They toss the camcorder into the lake and wash the ice pick before returning it to the drawer. Marin returns to her cottage and hears one final thwump, believing it was Mrs. Semple’s ghost ensuring the truth was found.

Marin feels a haunted, hollow feeling, knowing she just helped cover up a murder. She understands the other cast members—Susie, Heather, and Julianne—will believe the death was an accident.

Chapter 33: Analysis of the Journal

Marin reads the remainder of Mrs. Semple’s journal and learns “Azra” was the patient’s real name, with “Daisy” being the personality born of abuse. Mrs. Semple used hypnosis to try to eliminate the hallucinations, which Daisy perceived as her friends being murdered.

Mrs. Semple hung the clothes in the tree herself as part of the “therapy” to help Daisy let go of the imaginary women. Azra eventually “took over” and killed Mrs. Semple.

Marin realizes that because Daisy never existed as a separate spirit, she couldn’t have possessed Violet. This means Violet’s “possession” was a calculated performance, and Violet Wright is a murderer who faked everything to get away with killing Ronan.

Diary: June 6, 1926 (Semple’s Journal)

Ruth Hume Semple’s journal details how she brought Azra Kovacic to New Avalon as a patient suffering from paranoid schizophrenia and multiple personality disorder. The island served as a private psychological treatment facility, not a spiritual commune.

Mrs. Semple documents how Azra’s “Daisy” personality was born of severe childhood abuse. The other women—Katrina, Jonquil, and Phoebe—were hallucinations created by Azra’s fractured mind, and Mrs. Semple’s attempts to eliminate them through hypnosis were perceived by Daisy as murders.

The journal confirms that Mrs. Semple hung the dresses in the tree as a therapeutic exercise to help Daisy release the imaginary identities. The therapy ultimately failed when Azra’s original personality took control and killed Mrs. Semple.

Chapter 34: The Blackmail

Marin finds Violet on the dock, now calm and collected. Violet admits she always intended to kill Ronan because Elise Haines was her secret biological daughter, given up for adoption to save her career. They had reunited for a year before Elise died.

Violet dropped Mrs. Semple’s skeletal journal into the lake to destroy the evidence that Daisy was a fake, eliminating proof that the possession couldn’t have been real. Marin then reveals she saved the SD card from the camcorder before it was tossed.

Marin blackmails Violet, demanding to “be known” in exchange for her silence. Violet realizes she is now bound to Marin for life, and the two women become unwilling partners in crime.

Chapter 35: The Dock Confrontation

The boat arrives with Loretta to pick up the survivors. Marin realizes she now holds the power to change her entire life, looking at Violet, who stares back with fear.

Marin confirms she wants to be known, and she understands the movie Darkness will never be made. She prepares to leave the island behind forever, bidding a final farewell to Daisy Rue.

Marin understands that the truth of the island—the murder, the cover-up, and the blackmail—is now hers alone to hold. She steps onto the boat, forever changed by what happened on New Avalon.

Final Section: Four Years Later

Marin is at the Oscars, a Best Actress nominee who has won every precursor award. She is now a famous character actress playing lead roles, having achieved everything she ever wanted. Ronan’s death was officially ruled an accident, and Darkness was never made.

Susie Hutchinson told a spooky version of events to the press, but most of the cast remains silent due to their NDAs. Marin finds a 1931 photograph of a woman who looks exactly like Daisy Rue, identified as “Zara McCutcheon,” the wife of a Canadian bootlegger.

She concludes that the personality “Daisy” actually survived and escaped the island a century ago, starting a new life. Marin waits for her name to be called, finally achieving her dream of being “known”—a dream built on a foundation of secrets and lies.
