My Sister, the Serial Killer is a dark comedy about the bond between siblings. Korede is a nurse in Lagos and lives with her sister, Ayoola, and her mother. Her mother thinks Ayoola can do no wrong, but Korede knows otherwise. When her dinner is interrupted by a call from Ayoola saying a third boyfriend of hers is dead and she needs help clearing up, Korede goes to help. However, when Ayoola meets the cute doctor from Korede’s work, Korede has to think about whether she can continue to cover up her sister’s crimes.
This is a brilliantly pitched novel, a black comedy that delves into the darkness of Korede and Ayoola’s past and their father whilst also creating this image of Ayoola, the clothes-designing, social media loving serial killer sister. The chapters are short and the pace fast, like a thriller or a high stakes sitcom. Due to Ayoola targeting her boyfriends, the book will probably get comparisons with novels like Gone Girl, but it is far more focused on the sisters than on any of the men, on their bond than on revenge or anger at any man.
Clever and unputdownable, this is one to recommend to everyone who likes black comedy or wants a story about sisters with a bit of a twist. It could clearly be adapted for film or TV, but it works very well as a short, incendiary book that plays with the expectations of sibling rivalry and hiding crimes.
