My Sister the Serial Killer is a tale of two Nigerian sisters and three murders.

This is a tale of two Nigerian sisters. Some time ago, under circumstances unknown to us at the outset, Ayoola has killed their abusive father. Since then, she has murdered two other men for reasons that are at first obscure. She acts unconcerned and unashamed. And when her older sister, Kobede, asks her to give up the knife she used in all three murders, she refuses. It looks as though the killings will continue. This is the setup in Oyinkan Braithwaite’s explosive new debut novel, My Sister the Serial Killer.

A compelling tale of two Nigerian sisters and the men they love

Kobede is a nurse in a Lagos hospital. She’s infatuated with Tade, a handsome doctor who treats her with kindness but shows no awareness of her as a woman. Kobede is, in fact, unattractive, while her little sister is . . . no two words about it . . . gorgeous. But Kobede’s knowledge of medicine and human anatomy, and her obsessive use of cleaning materials, give Kobede an edge in her ongoing attempts to cover up her sister’s murders. Which she does on a regular basis. Then—no surprise—Ayoola sets her sights on Tade. And, clearly, nothing good will come from this.
