1. The New Tenant Arrival
Blake Porter secures a prestigious vice president marketing promotion at Coble & Roy in Manhattan after a previous employee named Quigley fails to jump out from the twenty-fifth-floor window because the glass only tilts open by three inches. Blake takes pride in handling intense pressure and long hours as a thirty-two-year-old professional.
Securing a tenant brings eccentric candidates to the brownstone before thirty-year-old waitress Whitney Cross passes background checks and moves in.
Wayne Vincent summons Blake after ten years and accuses him of sharing Henderson campaign data with rival firms. Wayne fires him immediately on the spot, denies him any severance or unemployment benefits, and threatens him with prosecution for theft.
After being fired, Blake hurls his gold-lettered nameplate against the office wall, fracturing it in half before leaving the building in disgrace. Sixty-two days of joblessness follow.
Financial Pressures and Interviews
Savings deplete rapidly while mortgage payments eat up remaining cash and two years of dating force Krista to offer her engagement ring. You face a severe financial crisis with two months until mortgage money completely runs out on your Upper West Side brownstone.
Blake and Krista interview several eccentric candidates to save their home, including:
- a kickboxing enthusiast who damages a wall;
- an aggressive dog owner;
- a man with a Linux hat who tries to drill into the wiring;
- an older woman in multiple robes calling herself Quillizabeth.
Quillizabeth spreads salt to keep away evil spirits and screams out a warning that Blake is going to crouch over Krista's bleeding body. Thirty minutes are allotted for these prospective tenant interviews below the ceiling measured at six feet five inches.
Whitney's Move-In
Whitney Cross applies for the room as a thirty-year-old waitress from Cosmo's Diner who packs all her sparse belongings into two boxes and two bags. Despite lingering internal doubts and alarm bells, a clean background check showing no warrants or arrests convinces you to accept her rent and security deposit.
Blake helps Whitney carry her minimalist belongings from her rusty red Ford Pinto into the brownstone while enduring insults from their eighty-something neighbor Zimmerly.
2. Escalating Household Tensions
Unexplained late-night thumping noises, skin rashes from limonene detergent, and bizarre psychic warnings create deep friction between Blake and Whitney.
Household Dynamics
You spend your days maintaining the brownstone and tending to household pets. Blake cleans the fish tank for their pet goldfish, Goldy, whom you consider a practice child.
You must follow specific steps to keep the goldfish alive:
- Extract twenty percent of the water from the fish tank.
- Mix replacement tap water with a dechlorinator before adding it.
- Remove debris from the bottom of the tank using a siphon.
Blake also accepts a low-paying temp job involving filing, data entry, and fetching coffee for younger colleagues. Blake's duties at his temp job include taking meeting minutes and getting coffee for his boss Kenny.
During a dinner party with friends Becky and Malcolm, Krista recounts how a previous potential tenant who claimed to be a psychic predicted Blake would stab Krista to death in their living room, causing visible discomfort and suspicion. Becky and Malcolm react with visible horror and suspicion when discussing the psychic's vision during dinner at their apartment.
Conflict with the Tenant
Tension rises when Blake suffers from an intense allergic rash across his chest and arms. Blake discovers an angry red rash covering his chest and arms in the men's room at his temp job.
You trace the reaction back to limonene, a citrus-scented fragrance chemical used in laundry detergent by Whitney. When Blake threatens to kick Whitney out, she informs him that she has legal rights under New York law. Blake realizes that he cannot legally force Whitney out immediately because New York law grants tenant rights even in the absence of a signed lease, requiring at least a thirty-day notice.
Further friction erupts from mysterious noises echoing through the brownstone. Blake wakes up at 1:18 AM to repeated thumping sounds from Whitney's room and confronts her.
3. Retaliation and Career Downfall
You find that household tensions reach a breaking point when you trace a persistent odor and a massive fruit fly infestation to the back of the refrigerator. You kill a dozen fruit flies on the counter and notice one hundred fruit flies trapped in each kitchen trap.
Rotting food, lipstick stains, and poisoned pets push Blake to retaliate while his past theft catches up with him at his new temp job.
Blake finds Styrofoam containers from a diner with moldy sandwiches and french fries in the fridge, and later discovers a maggot-filled paper bag of fruit on the top shelf of the kitchen cabinet. Convinced that Whitney placed the bag there to torment him, Blake retaliates. He uses a plastic bag to transport the rotting fruit and maggots from the kitchen cabinet into Whitney's bedroom, spilling them across her bed.
Rotting Food and Lipstick Sabotage
Your career struggles mirror the chaos at home during your temp job three blocks away from the office. You carry nine drink orders in a two-tier tray from Starbucks across two streets and complete the Starbucks coffee run in half an hour. Kenny questions Blake about twenty sandwiches ordered for a lunch meeting and checks CV backgrounds. Kenny calls Wayne Vincent, learns about Blake's termination at Coble & Roy, and confronts Blake, threatening that he will never work in town again if he steals.
Krista pulls a dress shirt out of the laundry basket, points out a bright red lipstick smudge on the collar, and accuses Blake of cheating. Blake meets Malcolm at Cooper's bar, where Malcolm got the VP job after Chad Pickering was caught doing drugs, prompting Blake to abandon the meeting during a sixty-degree walk home.
The Loss of Goldy and Past Betrayals
The conflict deepens at seven in the morning when Krista screams to wake Blake up over their dead goldfish. Blake smells bleach when fishing Goldy out of the tank with a net, and Krista cries over the death of their first pet as a couple despite the standard twenty percent water change percentage.
4. The Collapse of Domestic Trust
Systematically planted evidence destroys Krista and Blake's relationship, culminating in Krista moving out and a tragic neighborhood death.
During Goldy the goldfish's funeral in the backyard, Blake snaps and accuses Whitney of poisoning the fish, making Krista furious and deeply embarrassed. Whitney systematically plants Blake's cell phone in her own bed, her lipstick on his shirt collar, and bleach in their closet, convincing Krista that Blake is both cheating and unstable. Krista packs her suitcase and hails a taxi to leave the brownstone, ignoring Blake's pleas to stay.
Blake finds a mouthful of long brown hairs tangled in a container of cold lo mein noodles. Blake calls his dad, discusses Krista leaving, and agrees to visit Cleveland for Thanksgiving in two weeks.
Mr. Zimmerly's Tragic Death
Blake hurls a metal trash can in the direction of ninety-three-year-old Mr. Zimmerly during an argument on the street over the two days the trash cans were left out. Blake enters Mr. Zimmerly's house after a suspicious lack of response and finds his body in a pool of blood in the bathroom.
Blake reads the ingredient profile of his spilled laundry detergent at the laundromat and realizes limonene was added to cause his allergic reactions. Blake confronts a short man in a penguin hat by a newsstand who hisses that what Blake did to Whitney was disgusting after waiting ten minutes in line at the food cart.
5. Horrific Discoveries and Investigations
Detective Garrison arrives at your door at eight o'clock at night after you have consumed four or five bottles of beer. He reveals that ninety-something-year-old Mr. Zimmerly did not die from a bathroom slip, because his head trauma matches an antique clock found on his mantel.
Blake discovers a blood stain, severed fingers behind the refrigerator, and uncovers Whitney's dark past in Telmont.
Police Interrogations
You try to clean a half-foot-wide circular stain on your hardwood floor with wet paper towels and cleaner, only to realize the stain is dark red like blood. You sixty seconds later notice that the antique flea-market clock from your kitchen is missing. Malcolm visits you to return Krista's ring in a blue velvet box, claiming Krista needs space and wants you to sell the ring for money. Kenny calls you to chew him out for lying about having a fever and chills, ultimately firing you and telling you not to bother coming in the next day.
Attracted by house flies, you investigate the three-inch gap by the refrigerator. Blake uses a serving spoon to drag a hidden brown paper bag out from the narrow wedge, finding three human fingers with cotton candy pink painted nails.
The Road Trip to Telmont
After Malcolm refuses to lend his car, you rent a Corolla on your credit card and drive over two hours to Telmont, New Jersey. You arrive at 3:30 in the afternoon and stake out a pale yellow house belonging to Jeannette Cross. You call Telmont High School using a fake name to ask about Whitney Cross.
The secretary at Telmont High School tells you that after Jordan cheated on Whitney, she framed him for cheating on an exam, filled his locker with insects, and allegedly pushed him off the school roof. You realize that Whitney fifteen years ago attended the school in the fifteen-thousand-population town and left a trail of destroyed lives behind her.
6. Unmasking the Impostor
Character Revelations
Meeting a romantic partner's family can reveal hidden histories and alternate identities that completely alter your understanding of them.
Blake visits Mrs. Cross in search of answers, spots a family photograph on the mantel, and realizes the teenage girl in it is his fiancée Krista. When Whitney was 7 years old, she pushed her four-year-old brother Joey off a jungle gym. Three years after she vanished, Whitney sent her parents a postcard from Braga, Portugal. Six years later, the girl Jordan left Whitney for was found murdered.
The True Identity
Krista reflects on her past actions, including how she dealt with high school infidelity and betrayal, believing she did the world a favor by punishing those who wronged her. She recalls taking revenge on Jordan Gallo after finding out he cheated on her in high school. Unable to introduce Blake to her real mother, Krista hires a 52-year-old performance school student named Wanda to pose as her mother and rehearse specific background details like baking habits.
Krista hires a performance school student named Wanda to play her mother and meet Blake over dinner, coaching her on how to discuss baking snickerdoodle cookies. Wanda learns that butter must sit at room temperature for exactly fifteen minutes for Krista's cookie recipe. Through her contact Elijah, Krista discovers that the waitress named Whitney who took her name is actually Amanda Lenhart, a former PhD candidate in biology who stole Krista's identity and Social Security number.
Krista meets Elijah in a Manhattan park to discuss the waitress from Cosmo's Diner, and Elijah later reports that her real name is Amanda Lenhart. Krista hires an older psychic named Quillizabeth to visit their house and deliver a dramatic warning about Blake committing a violent crime, aiming to foster fear and paranoia. Krista hires Quillizabeth to pose as a prospective tenant and deliver a terrifying vision to Blake about him stabbing Krista with a kitchen knife.
Krista executes a detailed plan to make Blake and their new tenant Amanda despise each other by getting rid of cereal, hiding rotting apples to attract fruit flies, emptying toiletries, and lacing Blake's laundry detergent with an allergen.
- Pour cereal down the garbage disposal to provoke frustration over food sharing
- Place apples in a paper bag on a top cabinet shelf to rot and attract fruit flies
- Systematically empty shampoo, soap, and toothpaste from personal products
- Mix a small amount of fragranced detergent containing limonene into the hypoallergenic laundry bottle
Blake calls Stacie Parker from his car after fleeing Mrs. Cross's house, gets voicemail, and discovers a missing person post on Facebook from Stacie's roommate.
7. Revenge Murders and Climax
Krista murders Elijah and Stacie Parker, poisons Blake with tetrodotoxin, and attacks Amanda Lenhart in the brownstone.
Eliminating Liabilities
Even though Elijah was deeply infatuated with Krista and helped her obtain a fake Social Security card, a passport, and tetrodotoxin, Krista views him as a liability because he knows too much. After sleeping with him, she cuts his throat while he rests.
Krista visits Elijah in his fourth-floor walk-up in Brooklyn, collects the poison and identity documents, and kills him before wiping down the apartment.
Amanda confesses that Whitney Cross was a disappeared teenager. She bought the identity after borrowing money from a loan shark for her mother's expensive stomach cancer treatments, which ultimately failed.
Amanda breaks down on her maggot-infested bed and tells Krista her backstory after Krista reveals she knows the driver's license is fake.
Using sedatives and chloroform, Krista abducts Stacie by posing as an Uber driver. After Stacie confesses to sleeping with Blake in his office, Krista kills her in the New Jersey woods and leaves blood in the brownstone to implicate Blake.
Stacie falls for the fake Uber setup because Krista offers water bottles injected with sedatives, leading to her abduction and murder.
The Final Confrontation
Krista laces Blake's cookies with tetrodotoxin to induce a fatal respiratory failure. She administers a low dose of the lethal poison found in blowfish, intending for Blake to die slowly from respiratory failure, confusion, and paralysis so she can frame him for murder.
Blake eats the poisoned cookies, but later starts violently vomiting on the sidewalk, managing to purge part of the poison before his vision goes double while driving back to the city.
When Amanda decides she no longer wants to move into an apartment with Krista and prepares to leave, Krista seizes the opportunity. As the doorbell rings, Krista grabs a hidden knife from the coffee table and stabs Amanda.
Amanda is distracted by the doorbell ringing, allowing Krista to jam the blade of the knife deep into her belly.
8. Survival and Aftermath
Blake survives the tetrodotoxin poisoning, learns the true financial motives behind Amanda's actions, and relocates to Ohio.
Hospital Recovery
Blake spends a week in the hospital recovering after Krista poisons him with tetrodotoxin. Death from respiratory failure due to tetrodotoxin typically occurs within four to six hours. Surviving the initial twenty-four hours significantly lowers the chance of dying from the poison.
Relocation to Cleveland
Four months later, Blake packs his used Kia and leaves his brownstone behind to move back to Cleveland. He lived in New York City for over a decade before turning down a lucrative book deal and rejecting a return to his old toxic marketing job at Coble & Roy. He decides to take over his father's hardware store instead.
Blake repairs the brownstone so Amanda can facilitate its sale while living there rent-free. The house generates a bidding war among buyers eager to own the former home of a notorious murderer.
Amanda admits that her backstory about needing chemo money for her alcoholic mother was a fabrication. Frank Gallo, a loan shark, ambushes Amanda behind a diner one month before Krista's death and offers to erase her debts if she kills Krista Marshall for killing his nephew Jordan.
