Family loyalty becomes dangerously literal in Oyinkan Braithwaite’s darkly comic crime fiction. My Sister, the Serial Killer follows Korede, a meticulous nurse who repeatedly cleans up after her charismatic younger sister Ayoola kills her boyfriends, forcing Korede to choose between moral revulsion, jealousy and family allegiance. The novel is short, sharp and deliberately matter-of-fact about violence, using the sisters’ relationship rather than police procedure as its main source of tension. Braithwaite’s novella The Baby Is Mine turns a Lagos household during lockdown into another claustrophobic struggle over truth, possession and family claims. Her prose is spare, witty and fast, with satire sitting beside crime. The most useful neighbouring categories are Nigerian fiction, black comedy, literary crime and dark family stories. Read more Less
