Harriett Gilbert welcomes Nigerian author Oyinkan Braithwaite into the World Book Club studio to discuss her internationally bestselling debut, My Sister, the Serial Killer — a darkly comic thriller that has captivated readers around the globe.

This is the story of two sisters, Korede, the responsible and overlooked older sibling, and Ayoola, the beautiful younger sister with a deadly secret. When Ayoola’s boyfriends keep turning up dead, Korede finds herself in an impossible position — torn between loyalty to her sister and her own moral compass. Set against the backdrop of modern-day Lagos, this sharp, fast paced novel explores family, power, and the lengths we go to for those we love.

Oyinkan Braithwaite answers your questions about why are some forms of violence treated as ordinary while others shock us? How far does beauty allow someone to escape consequences? And what exactly defines the bond — or the burden — of sisterhood?
