    Summary of key ideas

    Understanding the Characters

    In My Sister, the Serial Killer by Oyinkan Braithwaite, we are introduced to Korede, a nurse in Lagos, Nigeria, who is the older sister of Ayoola. The story begins with Korede receiving a call from Ayoola, asking for help to clean up a mess. When Korede arrives at the scene, she discovers that Ayoola has killed her boyfriend, Femi, in an act of self-defense. This is the third time Ayoola has killed a boyfriend, and Korede has always been the one to help her cover it up.

    As the story progresses, we learn more about the sisters' childhood and their complex relationship. Korede has always been protective of Ayoola, who is beautiful and charming but also manipulative and self-centered. Ayoola, on the other hand, seems to lack remorse for her actions and is more concerned about her social media presence than the lives she has taken.

    The Doctor and the Sister

    At the hospital where Korede works, she has a crush on a handsome doctor named Tade. When Tade takes an interest in Ayoola and asks for her number, Korede is torn between her loyalty to her sister and her growing feelings for Tade. She is also worried about Tade's safety, knowing Ayoola's history with men. Despite her reservations, she gives Tade Ayoola's number, and they start dating.

    As Ayoola and Tade's relationship progresses, Korede becomes increasingly anxious about Tade's safety. She tries to warn him about Ayoola's past, but he dismisses her concerns, believing that she is just jealous of their relationship. Meanwhile, Ayoola continues her pattern of attracting men, and Korede is left to clean up the mess each time.

    The Unraveling of Secrets

    As the story unfolds, we see Korede struggling with her loyalty to her sister and her growing guilt over the lives they have taken. She begins to question her role in covering up Ayoola's crimes and starts to resent her sister's selfish behavior. At the same time, she is also grappling with her feelings for Tade and the guilt of keeping Ayoola's secrets from him.

    When Tade proposes to Ayoola, Korede is forced to confront the truth about her sister's dark side. She tries to warn Tade one last time, but he refuses to listen. In a desperate attempt to save Tade, Korede confesses everything to him, including her role in covering up the murders. Tade is horrified and ends his relationship with Ayoola, but he also decides to keep Korede's secret.

    The Final Act

    In the final act of the novel, Ayoola turns on Korede, blaming her for ruining her relationship with Tade. She attacks Korede, and in a moment of self-defense, Korede kills her sister. After Ayoola's death, Korede is left to deal with the aftermath of their shared secrets and the weight of her actions. She is consumed by guilt and grief but also feels a sense of relief that her sister's reign of terror is finally over.

    In conclusion, My Sister, the Serial Killer is a gripping and darkly humorous exploration of sisterhood, loyalty, and the consequences of covering up a serial killer. The novel raises thought-provoking questions about morality, guilt, and the lengths we go to protect the ones we love, even when they are the ones causing harm.
