My Sister, the Serial Killer by Oyinkan Braithwaite

Today is my younger sister’s birthday. I bought her this book as a joke gift, never intending to read it.

But, then I read good reviews and learned that it was up for both the Booker and the Woman’s Prize. So, with the deadline of my sister’s birthday approaching, I opened it up the other week and dove in.

Korede’s sister Ayoola has the inconvenient habit of killing her boyfriends, the latest named Femi:

“Femi makes three, you know. Three and they label you a serial killer.”

My Sister the Serial Killer is written by a Nigerian novelist, and is set in Lagos, Nigeria. Korede’s younger sister Ayoola is many things: beautiful, self-involved, vain, everyone’s darling, and yes, a serial killer. Korede works as a nurse and lives at home with her mother and Ayoola. She is fastidious in her job, but doesn’t really have any friends due to keeping her sister’s secrets and cleaning up her messes, literally.

We begin in the middle of the action: Ayoola calls Korede in the middle of the night for help — she has stabbed her newest boyfriend. Out of necessity, Korede has become an expert at crime scene cleaning and evidence concealment. (Bleach is the best way to remove blood if you’re wondering or know your own serial killer.) Her life has become move the body, dispose of the body, clean up after the body, and hardest of all — stop her sister from carrying on with her social media posting as if nothing happened – and advising Ayoola to at least act sad about her latest ‘missing’ boyfriend.

But, everything changes when Ayoola sets her sites on a doctor Korede’s secretly in love with. Forced to sit back and watch in utter fear as Ayoola successfully flirts with him, Korede is faced with an inner battle to save the man she loves or to protect her sister.

Driven by her passion, and the fear she and her sister might get caught ~~ because, oops, Korede confessed everything to a patient who was in a coma but is now awake—Korede makes choices she never even imagined were possible.

The sisters’ story goes back and forth from their troubled childhood, to the present, to the near past, and onward. The story becomes deeper and more nuanced than one would first assume — as more history is revealed.

Nigerian culture is sprinkled throughout. There’s the heat, the food, and the traffic. The police are portrayed as corrupt and easily bribed. Even though their dead father was cruel and abusive, the mother and daughters are expected to host the annual lavish party to remember him.

My Sister, The Serial Killer isn’t a crime novel as such – there’s no mystery and no detection. It’s really the story of sisters and their relationship — the loyalty and the rivalry. It’s often darkly funny, but also tense, and unexpectedly poignant. There’s a scene where Ayoola is happily lapping ice cream while her (murdered) boyfriend’s sister is sobbing in grief — which stopped me cold.

This is a short little novel which you could read in one sitting, but you’ll want to linger, as it’s a very artfully written book. And, as an added bonus, you’ll learn how to clean a crime scene – just in case a family member goes rogue.

Happy Birthday to my wonderful sister, who, as far as I know, is not a serial killer.
