BookBrowse Reviews My Sister, the Serial Killer by Oyinkan Braithwaite

BookBrowse:

In this twisted black comedy, a Nigerian woman hides her younger sister's murderous secret at great personal cost.

While the title of the novel gives away the plot, My Sister, the Serial Killer is essentially a character study of its narrator, Korede, a Nigerian woman attempting to simultaneously protect her sister, and protect the world from her sister. The siblings' complicated relationship gradually unfolds over the course of the novel in flashbacks, and a sinister family history is alluded to in a piece of deft symbolism. Korede notes that there is a painting in her home that her father commissioned depicting their house, and she recalls:

As a child I would go stand before it and wish myself inside. I imagined that our alternates were living within its watercolor walls. I dreamt that laughter and love lay beyond the green lawn, inside the white columns and the heavy oak door.

When the novel begins, Korede's beautiful younger sister Ayoola has just killed for the third time, each victim a romantic partner. As the elder sister, Korede feels she is responsible for taking care of Ayoola, and thus keeps her secrets and helps dispose of the bodies. However, when Ayoola sets her sights on Tade, a handsome doctor at the hospital where Korede works, Korede is thrown into a spiral of confused loyalties. Not only is Tade a great doctor and a good person, Korede has feelings for him as well. How can she dissuade Tade from dating Ayoola without giving away Ayoola's secret? How can she convince her selfish, spoiled sister to find a new boyfriend? The tension escalates as Ayoola and Tade grow closer and Korede's tactics continually fail to derail the inevitable collision.

More than anything, this is a book about sibling rivalry, the serial killer situation is merely a device of exaggeration to explore this theme. As the older sister constantly cleaning up her younger, prettier sister's (literal) messes, Korede feels like one of the most aggrieved characters in all of literature. Her feelings of inferiority are often played for comedic effect, as when she declares, "Ayoola looks like a Bratz doll and I resemble a voodoo figurine," but there is a profound sadness and vulnerability at Korede's core that is highlighted just often enough to be deeply affecting. One of these moments occurs as Korede remembers being teased by boys in high school. When Ayoola started at the school two years later, Korede imagined she would have to comfort her sister after she faced similar ridicule, but instead, Ayoola was asked out by a senior on her first day. It was in this moment that Korede first realized she was different from her sister, and the wound is still raw many years later.

As a character study, My Sister, the Serial Killer is captivating. Korede is being squeezed in a vise of uncertainty as her loyalty and morality are put to the ultimate test. However, with so much focus on the narrator, the secondary characters are barely sketched in. This lack of development is particularly discernible with regard to Ayoola. Given no access to her mind or details about her personality, one wonders what makes her tick, and how she feels about the things she has done. Guilty? Justified? Who knows. The sisters' backstory includes a hint at motive, but it would have been nice to know more. Nevertheless, Braithewaite has constructed a taut narrative, rich in psychological intrigue with just enough dark humor to break the tension.
