Oyinkan Braithwaite is a Nigerian-British novelist born in Lagos in 1988 who studied creative writing and law at Kingston University. Before becoming a full-time writer, she worked as an assistant editor at Kachifo Limited and as a production manager at Ajapa World. Her debut novel My Sister, the Serial Killer earned her recognition as a finalist for the Booker Prize and winner of multiple international awards.
My Sister, the Serial Killer explores codependent sisterhood, beauty privilege, and the lengths family loyalty can stretch. Braithwaite examines how physical appearance determines romantic success, with beautiful Ayoola easily attracting men while plain Korede is overlooked. The novel also critiques toxic family bonds, questioning whether blood truly justifies protecting a serial killer, while satirizing romantic love as superficial and appearance-dependent.
My Sister, the Serial Killer is primarily a dark comedy disguised as a thriller. While the premise involves serial murder, reviewers note the novel satirizes thriller conventions rather than building traditional suspense. Braithwaite's blunt narrative style, deadpan humor, and opening "how to get away with murder" guide establish a comedic tone that examines sister dynamics and social commentary more than creating genuine thrills.
Korede and Ayoola represent opposite ends of beauty and personality spectrums in My Sister, the Serial Killer. Korede is practical, caring, and overlooked, working as a nurse while enabling her sister's crimes. Ayoola is beautiful, self-absorbed, and potentially sociopathic, claiming self-defense despite no physical evidence. Their codependent relationship explores how family trauma and beauty standards create toxic bonds where actions speak louder than words.
My Sister, the Serial Killer critiques how physical appearance dictates women's value and romantic prospects. Beautiful Ayoola effortlessly attracts men and escapes suspicion despite killing three boyfriends, while conventionally plain Korede is romantically invisible despite her competence and kindness. Braithwaite demonstrates that beauty carries dangerous power, allowing attractive women to manipulate situations while unattractive women are dismissed, regardless of character or capability.
My Sister, the Serial Killer won:
The novel was longlisted for the 2019 Booker Prize and shortlisted for the Women's Prize for Fiction. It became the second-highest bestselling Booker longlisted title in 2019.
My Sister, the Serial Killer uses Lagos as an atmospheric backdrop that shapes the story's themes and tensions. The Nigerian setting influences family dynamics, social expectations around beauty and marriage, and the practical challenges of disposing evidence. Braithwaite's familiarity with Lagos adds authenticity to the narrative, making the city more than scenery—it's a character that informs cultural attitudes toward sisterhood, appearance, and family loyalty.
Critics of My Sister, the Serial Killer note the novel prioritizes Korede's unrequited romance over the serial killing premise, disappointing readers expecting sustained thriller tension. Some reviewers found the story emotionally contained and lacking character development, particularly wishing Korede had chosen herself over her toxic sister. The brevity, while praised by many, left others wanting deeper exploration of motivations and psychological complexity behind Ayoola's murders.
My Sister, the Serial Killer is a concise novel with a stripped-down narrative style focusing on essentials. The book's brevity is intentional, matching its blunt, emotionally contained storytelling approach. This compact structure allows Braithwaite to deliver sharp social commentary and dark humor without excessive exposition, making it an impactful quick read that maintains intensity while exploring complex themes of family, beauty, and loyalty.

Korede knows the drill. Bleach masks the smell of blood. First, scrub the bathroom tiles. Then, wipe down every surface that might hold a fingerprint. While she methodically erases the crime scene, her sister Ayoola sits perched on the toilet, scrolling through Instagram, her designer dress still stained with her boyfriend's blood. This is the third time Ayoola has called Korede with those chilling words: "I killed him." Three victims makes it official-Ayoola is a serial killer, and Korede is her reluctant accomplice. What makes this relationship so compelling isn't just the murder, but the stark contrast between the sisters' reactions to it. While Korede meticulously cleans, checking and rechecking surfaces, Ayoola seems utterly unbothered. She can't even remember Femi's surname, yet recalls with perfect clarity every word of the poem he wrote praising her beauty. When asked why she was carrying the knife that killed him, Ayoola's answer is simple: "For protection." Against what? Against men who "want what they want when they want it."
