Plot Summary

Prologue

The call comes at night. Ayoola2's voice on the phone delivers the words Korede1 hoped never to hear again: she has killed him. Korede1 drives to Femi's apartment, where she finds her beautiful younger sister2 perched on the toilet seat, blood dried on her dress, and a man's body slumped in the bathroom.

For three hours, Korede1 scrubs every surface with bleach, working blood out from between the shower and the caulking, erasing all traces of life and death. Then they wrap Femi in bedsheets, navigate the elevator past a young mother, and load him into the boot of her car.

They drive to the Third Mainland Bridge in the pitch-black early morning and heave him into the lagoon, where two prior bodies already rest. This is the third time Korede1 has answered this summons. She is not angry, only exhausted.

May contain spoilers
Analysis

The opening ritual establishes the novel's central sacrament: bleach as erasure, cleaning as secular confession. Korede's methodical labor, the three hours of scrubbing while Ayoola perches childlike on the toilet, maps their dynamic instantly. One sister acts on impulse, the other absorbs all consequence. The detail that bleach masks blood's smell but fails at cleaning residue becomes a metaphor for the entire arrangement: surfaces can be sanitized, but something always lingers. Femi's body joining two predecessors beneath the bridge transforms Lagos infrastructure into an unmarked cemetery. The prologue plants the question that drives everything that follows: not whether Ayoola will kill again, but how much weight Korede can carry before the structure collapses.

The Notebook's Grim Purpose

Korede records victims while Ayoola recites a love poem

Back home, Korede1 writes Femi's name in a small notebook originally purchased to record daily happiness after watching a TEDx video. Ayoola2 cannot recall his surname, but she remembers every line of the poem Femi wrote to woo her.

She recounts the killing: they dated one month, he became aggressive over messages on her phone, cornered her, and she stabbed him in self-defense with a knife she carries for protection. Korede1 notes the inconsistencies. At St. Peter's Hospital, where she works as a nurse, Korede1 maintains meticulous order.

Her white uniform remains pristine while others' yellow. She harbors secret feelings for Tade,3 a handsome doctor whose singing voice calms screaming children. She also visits room 313, where a comatose professor named Muhtar4 has become her silent, unwitting confessor.

May contain spoilers
Analysis

The notebook's transformation from gratitude journal to death ledger mirrors Korede's psychological trajectory: a life meant for living has been annexed by the demands of covering for death. Ayoola's inability to remember Femi's surname while reciting his poem verbatim exposes the asymmetry of her relationships. She absorbs adoration, not identity. The hospital offers Korede a parallel domain where she can maintain antiseptic control, even as her car boot carries ammonia stains. Muhtar, the coma patient, represents the ideal listener for a woman who cannot speak aloud: present, receptive, and structurally incapable of judgment or betrayal.

Tade's Eyes Find Ayoola

A hospital visit sparks his instant, irreversible infatuation

Ayoola2 arrives at St. Peter's during Korede1's shift, wearing a yellow dress that turns every head in reception. She claims she wants lunch, but when Tade3 emerges, his eyes dilate and settle on her with a focus Korede1 has never received. He asks for Ayoola2's number.

Soon she visits his office, saving her contact in his phone, accepting lunch dates at the restaurant Korede1 once introduced him to. Tade3 sends a bouquet of violently bright orchids. Ayoola2 texts back that she prefers roses.

When spectacular red and white roses arrive, Korede1 creeps downstairs at night and tears every petal from both bouquets until the floor is covered. In the morning, their mother5 shrieks at the destruction. Ayoola,2 without being asked, claims she destroyed the flowers herself after a fight with Tade.3

May contain spoilers
Analysis

Tade's instant capitulation to Ayoola's beauty confirms Korede's lifelong education: desirability is a currency she was born without. The destroyed flowers mark a rare moment of Korede acting on impulse rather than cleaning up after others. Ayoola's reflexive cover-up of Korede's vandalism inverts their usual dynamic, hinting that she understands the debt and can protect her sister in small ways even as her larger actions generate endless cleanup work. The episode crystallizes Korede's double bind: she resents Ayoola for taking what she wants, yet depends on that same person for the only protection she receives.

Police Take the Car

A bloody napkin and a neighbor prompt official scrutiny

Femi's disappearance trends on social media. Ayoola2 posts a manipulated message positioning herself as the grieving last girlfriend. When Femi's mother calls, Ayoola2 puts the phone on speaker, and both sisters cry, though only Korede1's tears carry genuine guilt.

A neighbor reports seeing two women leave Femi's apartment. A cleaner discovers a bloody napkin down the back of his sofa, and the news spreads on Snapchat. Police officers arrive at the family home to question Ayoola.2 Korede1 coaches her to keep answers short and maintain eye contact.

Ayoola2 performs flawlessly. The officers then seize Korede1's silver Ford Focus for forensic examination. For days, Korede1 lives in terror that her ammonia-and-water mixture failed. The car returns clean. The officers demand a five-thousand-naira bribe for their trouble.

May contain spoilers
Analysis

Ayoola's performances for Femi's mother and the police reveal her as a consummate actress whose beauty functions as perpetual alibi. The scene crystallizes the book's central paradox: the person society instinctively trusts because of her face is a serial killer, while the plain older sister who methodically eliminates evidence is the one who understands consequence. The police bribe for returning a clean car underscores the Lagos setting, where institutions are transactional and truth is a negotiable commodity. Korede's relief at the clean forensics is poisoned by the recognition that her competence has again ensured Ayoola's impunity.

The Father's Deadly Heirloom

Childhood beatings and a curved knife explain the sisters' bond

Through fragmented memories, the sisters' childhood surfaces. Their father,6 a wealthy businessman and serial philanderer, kept a nine-inch curved blade he displayed to guests with invented origin stories: a gift for saving a life, a trophy from a soldier, payment from a sheik.

Only when polishing the knife with rotor oil did he show tenderness. He beat the girls with a carved cane, punishing Ayoola2 viciously for attracting male attention. When a visiting chief showed predatory interest in fourteen-year-old Ayoola,2 their father6 seemed to weigh a business arrangement rather than intervene.

The night before he died, he was beating Korede1 when he suddenly collapsed. The sisters stood over him, for once taller, and watched his life drain away. Ayoola2 took the knife from his study before his body was cold.

May contain spoilers
Analysis

The father's knife functions as a phallic symbol of patriarchal violence that passes from abuser to abused as a dark inheritance. Ayoola's appropriation of the weapon after his death is not theft but succession: she has absorbed his capacity for harm, his absence of remorse, his belief that the powerful author their own justifications. The beatings triggered by her desirability created the psychological template for her killings. Men who desire her activate the same violence her father used to punish that desirability. The knife, polished with more love than he ever showed his daughters, becomes the instrument that reenacts his brutality on every man who looks at her the way the chief did.

Warnings Spoken, Then Dismissed

Tade rejects Korede's caution and accuses her of cruelty

When Tade3 confides his heartbreak over Ayoola2's growing distance, Korede1 tells him he is better off without her. Tade3 stiffens. He accuses Korede1 of failing to support her sister, of being jealous and unkind. Ayoola,2 he reveals, has already told him that Korede1 treats her like a monster.

Korede1 tries to explain that Ayoola2 has many sides, not all as pretty as the one he sees, but Tade3 dismisses this as confirmation of her bitterness. He declares that what Ayoola2 needs is love and stability to settle down.

Korede1 realizes she has lost. Beauty speaks louder than any warning. Later, in Muhtar4's room, she rails against a world where pretty women get a pass at life while plain women do the scrubbing. Muhtar4's silence offers the only absolution she can receive.

May contain spoilers
Analysis

Tade's rejection of Korede's warning illustrates the epistemic injustice at the novel's heart: the beautiful are believed, the plain are dismissed as bitter. Tade cannot hear truth from a woman he does not desire. His conviction that his love can settle Ayoola is a specifically masculine delusion: the belief that a good man's devotion can cure a woman's damage. Korede's isolation deepens. Her only confidant is a coma patient who cannot repeat her words, a fact that keeps her returning to room 313 not for medical reasons but because Muhtar is the sole person to whom she can speak without consequence.

Dubai and a Fourth Death

A married lover dies abroad, and Ayoola's methods evolve

A wealthy married businessman named Gboyega8 arrives at the house with roses. Korede1 discovers he funded Ayoola2's fashion course, capital she claimed came from her own YouTube earnings. Ayoola2 travels with him to Dubai. While there, Gboyega8 dies suddenly.

Official reports list a drug overdose, but Ayoola2 describes watching him froth at the mouth from apparent food poisoning. Dubai police keep her name out of the news. Korede1 searches online and finds Gboyega8's wife's Instagram: anniversary tributes, family photographs, a woman who still believes her husband was faithful.

Korede1 adds Gboyega8's name to the notebook. This is the fourth death connected to Ayoola,2 but the first without the knife, suggesting her methods are expanding. Korede1 wonders whether Ayoola2 was even provoked this time.

May contain spoilers
Analysis

Gboyega's death marks an escalation: Ayoola may now kill without the knife and without the justification of physical threat. The Dubai setting takes the pattern international, suggesting impunity is portable. Korede's discovery that Ayoola lied about funding her business adds financial predation to the list of manipulations. The notebook, now bearing multiple names, has transformed from memorial into indictment, yet Korede continues writing rather than confessing. Her research into Gboyega's wife, her vicarious grief for a woman she will never meet, suggests she performs the mourning that Ayoola cannot feel. The death also functions as a dark preview of what might happen to Tade.

The Coma Patient Remembers

Muhtar awakens with fragments of Korede's darkest confessions

After months unconscious, Muhtar4 regains consciousness. When Korede1 visits, he recognizes her voice instantly. He remembers fragments of her monologues, including her statement that her sister2 is a serial killer. Korede1's blood runs cold.

She tries to convince him these were coma-induced hallucinations, but Muhtar4 is thoughtful and watchful. He requests Korede1 as his designated nurse. In subsequent visits, he quotes Jim Morrison about how loving families commit a subtle kind of murder by forcing people to destroy who they really are. He tells Korede1 he will not report what he remembers.

The words of a coma patient would carry little weight, he notes. But more than that, he feels loyalty to the voice that called him back from the void. Korede1 has found, for the first time, a living person who knows her secrets and chooses to protect her anyway.

May contain spoilers
Analysis

Muhtar's awakening transforms him from passive confessor into active witness, now complicit in Korede's secrets. His quotation about families committing murder articulates the novel's thesis: the deepest violence is not Ayoola's blade but the family system that makes covering for her obligatory. Muhtar's decision to protect Korede rather than report Ayoola makes him the first person who has chosen Korede over her sister. Yet his protection is conditional and uncertain; his recovering memory becomes a ticking clock. Korede's relief at his silence is shadowed by the knowledge that what one person remembers, others might eventually assemble.

The Engagement Ring Shattered

Korede destroys Tade's proposal and an innocent man pays

Tade3 summons Korede1 to his office and reveals a velvet box containing a two-carat princess-cut diamond ring. He intends to propose to Ayoola.2 Korede1 laughs uncontrollably, then pleads with him to reconsider. When pressed to name what he loves about Ayoola,2 Tade3 can only list her beauty and the intensity of his wanting.

He knows nothing of her substance. Desperate, Korede1 finally speaks the words she has only whispered to Muhtar:4 Ayoola2 has killed before. Tade3 dismisses this as cruelty.

Ayoola2 has already told him a preemptive version in which Korede1 blames her for an accidental death. After Tade3 leaves, Korede1 breaks into his office, smashes the ring setting against the floor, pockets the diamond, and stages a burglary. The cleaner Mohammed is blamed and fired. Tade3 suspects Korede1 but lacks proof.

May contain spoilers
Analysis

The ring destruction marks Korede's first independent act of sabotage, a departure from her usual role of cleaning up after the fact. She crosses from accessory to actor, deploying the same skills of misdirection and scene-staging developed through covering Ayoola's crimes. Mohammed's firing exposes the collateral damage of the sisters' dysfunction: the poor absorb the cost of the privileged. Tade's inability to articulate what he loves about Ayoola beyond her appearance confirms Korede's bleak worldview: love is aesthetic preference dressed in romantic rhetoric. His readiness to believe Ayoola's preemptive lies over Korede's desperate truth shows how thoroughly beauty organizes his cognition.

The Knife Finds Its Inheritor

Ayoola is stabbed, and Korede must choose a story

Ayoola2 calls Korede1 to Tade3's house. When Korede1 arrives, she finds her sister2 on the bedroom floor with the knife, her own knife, protruding from her side. Tade3 stands over her, sweating, insisting Ayoola2 attacked him first after he confronted her about the warnings regarding Femi.

He says he acted in self-defense. Ayoola,2 bleeding and pale, gives Korede1 a weak smile and murmurs about irony. Korede1 bandages the wound with the blade still in place, drives Ayoola2 to St. Peter's, and makes her choice.

When Ayoola2 wakes in her hospital bed, she tells the police a different story: Tade3 proposed, she declined, and he stabbed her in rage. Korede1 backs the story without hesitation. Tade3 is arrested. Ayoola2 later explains she attacked him because he had figured out Korede1's involvement in Femi's death and threatened to report her.

May contain spoilers
Analysis

The climactic stabbing inverts every expectation. For the first time, Ayoola is the one bleeding, and a man fought back successfully. The knife, passed from father to daughter, has finally turned against its inheritor. Korede's decision to drive Ayoola to the hospital herself rather than call an ambulance, which would have let Tade tell his story first, reveals her priority: control the narrative. Ayoola's accusation flips predator into prey with practiced expertise, weaponizing the cultural script of the violent rejected male. Korede's corroboration is her final moral surrender. She has chosen sisterhood over justice, blood over truth, and she knows exactly what the choice cost.

Tade Pays the Price

An innocent man is imprisoned while the sisters remain free

The investigation concludes. Multiple colleagues testify to Tade3's gentle character, but the physical evidence is incontrovertible: Ayoola2 was stabbed in his home with the knife logged into hospital inventory after her surgery. His medical license is revoked, and he serves a jail sentence for assault.

Korede1 does not visit him. She has no desire to know what he thinks or feels. Muhtar4 is discharged from the hospital and gives Korede1 his phone number on a slip of paper, an offer of continued connection beyond the hospital walls, perhaps friendship, perhaps something more.

In room 313, now empty, Korede1 sits in her usual chair and breathes in his lingering scent. She feels an intense sense of loss, not for Tade,3 who is also gone, but for Muhtar4 and the sanctuary his unconsciousness once provided.

May contain spoilers
Analysis

Tade's punishment for defending himself completes the novel's bleak arc: the only innocent person in the triangle pays the highest price. His colleagues' testimonials become a collective shrug against the machinery of gendered assumptions about violence. Korede's refusal to visit him is not cruelty but self-preservation; looking at him would mean confronting the magnitude of what she has done. Muhtar's phone number, written on paper and tucked into her uniform pocket, represents the road not taken: confession, accountability, a life outside the gravitational field of Ayoola's needs. The empty room 313, with its unchanged linens, is a tomb for the woman Korede might have become.

Epilogue

At home, Korede1 holds Muhtar4's phone number. She has keyed in the digits and cleared the screen three times. The paper softens in her fingers. She lights a candle on her nightstand and holds the slip over the flame until the numbers curl into ash and fire licks her fingertips.

There will never be another Muhtar,4 she tells herself. There will never be another chance to confess or absolve herself. Ayoola2 needs her more than she needs untainted hands. The house girl interrupts: a guest has arrived.

Korede1 walks downstairs to find Ayoola2 and their mother5 already entertaining a new man. Ayoola2 introduces her sister.1 The stranger smiles at Korede,1 and Korede1 smiles back. The cycle holds. Somewhere under the Third Mainland Bridge, the bodies drift. The knife waits in its hiding place for the next hand.

May contain spoilers
Analysis

The burning of Muhtar's number is Korede's self-administered last rite, a deliberate foreclosure of any path that might lead away from Ayoola. Fire, which the sisters once used to destroy their first victim's apartment, links all Korede's acts of destruction into a single ritual of concealment. The arrival of a new man, met with Korede's practiced smile, confirms that nothing has changed and nothing will. The novel refuses redemption, insisting instead on the unglamorous truth that some bonds are preserved not by love but by shared secrets, and that complicity, chosen enough times, calcifies into identity. The final image of the knife waiting in hiding transforms the object from evidence into prophecy.

Analysis

Oyinkan Braithwaite's novel operates as a dark fable about the economies of beauty and the wages of unconditional familial loyalty. At its center is a question the narrative refuses to settle: is Ayoola2 a traumatized survivor who kills in self-defense, or a predator who has learned that her face will always provide an alibi? The ambiguity is the point. The novel argues that in a patriarchal society, the line between victim and perpetrator is drawn by the same forces that determine whose testimony carries weight.

Korede1's first-person narration places readers inside the psychology of complicity. She is not a passive enabler but an active participant whose meticulousness makes Ayoola2's impunity possible. Her cleaning rituals function as sacraments of erasure, a secular confession that purifies surfaces while indelibly staining the soul. The short, vignette-style chapters mirror her fragmented consciousness: memories of paternal abuse and present-day crises collide without transition, replicating the way trauma organizes experience.

The sisters' codependency was forged in shared violence. Their father6's beatings, his transactional view of women, and his near-sale of Ayoola2 to a predatory chief constitute the original crime from which all subsequent crimes flow. When Ayoola2 kills, she reenacts what was done to her, but she also replicates her father6's impunity, his assumption that the powerful need not account for their actions. Korede,1 who absorbed the complementary lesson that the plain must serve the beautiful, has constructed her entire identity around being useful, being needed, being the one who mops up.

The Lagos setting is integral rather than decorative. The Third Mainland Bridge, where bodies are discarded, is also where a real bus plunged into the lagoon, a detail that naturalizes death as part of the urban landscape. Corrupt police, transactional institutions, and a social media culture that forgets missing persons within weeks create an environment where accountability is negotiable and where the beautiful navigate life on an easier setting.

The ending refuses catharsis. Korede1 burns Muhtar4's phone number and smiles at a new man arriving at the house. The cycle will continue because it must. What the novel ultimately argues is not that Korede1 should have turned Ayoola2 in but that love, in certain families, is structurally indistinguishable from a hostage situation, and that walking free sometimes means never walking away.

Characters

Korede

Elder sister, nurse, cleaner of crimes

The narrator, a tall, plain-looking head nurse at St. Peter's Hospital. Pragmatic, meticulous, and deeply repressed, she has spent her life managing the consequences of Ayoola2's actions. Her competence at erasing bloodstains is matched only by her inability to assert her own desires. She loves Tade3 silently, watching him fall for Ayoola2 with the same resignation she brings to bleaching bathrooms. Her relationship with Muhtar4, the comatose patient, provides the only space where she speaks freely. She is driven by a sense of responsibility instilled since childhood: big sisters protect little sisters. Her tragedy is that her protective instincts have made her complicit in murders she morally condemns, and she cannot imagine an identity outside serving her sister2's needs.

Ayoola

Younger sister, fashion designer, killer

Stunningly beautiful, petite, and childlike, Ayoola designs clothes and models them on social media. She is impulsive, guileless in her selfishness, and seemingly incapable of genuine remorse. She kills men who love her, then calls Korede1 with the same casual expectation one might use to request a ride. Her beauty is her shield; people instinctively trust her, desire her, and forgive her. She carries their dead father6's curved knife as both talisman and weapon. Beneath her carefree surface lies a survivor of brutal paternal abuse, but whether her killings stem from trauma or something more predatory remains deliberately, permanently ambiguous. She understands her power over others with an instinct that needs no reflection.

Tade

Kind doctor, Korede's unrequited love

A gentle, soft-spoken doctor at St. Peter's who sings to calm frightened child patients. He is an only child, idealistic to the point of naivety, and wholly unequipped to recognize darkness in a beautiful face. He falls for Ayoola2 instantly and completely, unable to see past her surface. He genuinely believes his love can heal whatever wounds he assumes she carries. His friendship with Korede1, once warm, erodes as she tries to warn him. He is not a bad man, but his shallowness about what draws him to Ayoola2 makes him complicit in his own destruction. He deserves better than the story gives him.

Muhtar

Comatose professor, Korede's confessor

A professor who spent months in a coma at St. Peter's following a car accident. During his unconsciousness, Korede1 confided everything to him, treating his silent body as a sealed confessional. When he awakens, he remembers fragments. Sharp, philosophical, and weary of human folly, he quotes Jim Morrison and understands the moral complexity of family loyalty. His failed marriage, ended by triple talaq, and his difficult adult children give him a wry perspective on duty and disappointment. He is the only person who has ever chosen Korede1's wellbeing over Ayoola2's beauty.

Mother

Widow in denial, Ayoola's enabler

Widow of the abusive patriarch6, living in willful denial about both her late husband6's monstrosity and her younger daughter2's violence. She openly favors Ayoola2, treating her beauty as the family's greatest asset, and pressures both daughters to marry. She witnessed her husband6's brutality and infidelity but never intervened, retreating instead into Ambien, romance novels, and elaborate gele headwraps. Her response to any suggestion of Ayoola2's wrongdoing is reflexive disbelief and an immediate pivot to blaming Korede1. She has built a life on not seeing what she cannot bear to acknowledge.

Father

Dead patriarch, source of the knife

Dead for a decade when the novel begins. A wealthy, corrupt businessman who beat his daughters with a carved cane and flaunted his mistresses before his wife. He polished his prized curved knife with more tenderness than he ever showed his family. His sudden death, a collapse while beating Korede1, was witnessed by both girls, who stood over him and watched him die. His knife became Ayoola2's most treasured possession. His violence, his transactional view of women, and his impunity created the psychological landscape his daughters still inhabit.

Yinka

Hospital receptionist, office gossip

A nurse at St. Peter's who sleeps on the job, paints her nails at reception, and takes pleasure in needling Korede1. She is awed by Ayoola2's beauty and openly mocks Korede1's attempts at femininity. Petty but perceptive in the way of workplace gossips.

Gboyega

Wealthy married lover, fourth victim

A married oil and gas executive with three sons and a wife on Banana Island. He funded Ayoola2's fashion course and took her to Dubai, where he died suddenly of what was officially recorded as a drug overdose. His death is the first connected to Ayoola2 without use of the knife, suggesting her methods are evolving beyond her signature weapon.

Plot Devices

The Father's Knife

Inherited weapon, symbol of transferred violence

A nine-inch curved blade with black comma-like markings on a pale bone hilt, kept sheathed and locked in the father6's desk drawer and displayed to guests with elaborate fabricated origin stories. Ayoola2 took it after his death. She carries it in her handbag as habitually as other women carry tampons, and it is the weapon used in the stabbings that Korede1 must then clean up. The knife carries the weight of paternal violence across generations, transforming victim into perpetrator. Korede1 occasionally wonders whether the blade possesses its own agenda, directing the hands that hold it, a supernatural possibility the novel entertains without confirming.

The Small Notebook

Death ledger disguised as gratitude journal

A notebook smaller than Korede1's palm, originally purchased with the intention of recording one happy moment each day after she watched an inspirational TEDx video. The first entry reads: 'I saw a white owl through my bedroom window.' After that, the pages remained mostly empty until Korede1 began using it to record the names of Ayoola2's victims, starting with Femi. The notebook's transformation from gratitude journal to death ledger encapsulates Korede1's psychological arc: a life meant for living has been annexed by the demands of concealing death. It sits in her room as a private indictment she will never share.

Bleach and Cleaning Supplies

Tools of erasure, ritual of concealment

Korede1's intimate knowledge of cleaning chemistry, bleach in particular, is the practical foundation of every cover-up. She knows bleach masks the smell of blood but is not ideal for residue, so she uses it only after first scrubbing thoroughly. Her homemade ammonia solution removes blood from car upholstery. Her hospital supply cabinet contains gloves, multi-surface cleaners, and odor-shield trash bags. Cleaning is simultaneously her practical skill, her psychological coping mechanism, and the act that makes her morally complicit. When anxious, she cleans bathrooms. The pristine surfaces she creates mirror the spotless lies the family tells.

Muhtar's Coma

Silent confessional, ticking time bomb

Muhtar4's prolonged unconsciousness creates a narrative device unique to this story: a confessor who can hear but cannot repeat. Korede1 visits room 313 to tell him everything she cannot tell anyone else, including her doubts about Ayoola2's self-defense claims and her love for Tade3. The coma provides a sealed space where secrets can be spoken without consequence. When Muhtar4 awakens, this safe space collapses. His patchy but recovering memory becomes a suspense mechanism: what does he remember, and what will he do with it? His unexpected loyalty transforms the device from threat into the novel's only gesture toward grace.

Instagram and Snapchat

Public stage for performance and exposure

Social media operates as both Ayoola2's tool and her potential undoing. She manipulates it masterfully, posting grieving-girlfriend content about Femi's disappearance that deflects suspicion and solicits sympathy. Her fashion brand depends on her online image. But the same platforms threaten exposure: Femi's sister posts his poetry and the neighbor's eyewitness account, and a cleaner's discovery of a bloody napkin goes viral. Social media is the arena where Ayoola2's beauty performs its most effective alibis and where the public's short attention span, shifting from missing persons to jollof rice debates, becomes an unwitting accomplice to her impunity.
