Nigerian Novel ‘My Sister The Serial Killer’ to become Full-length Feature

UK production company Working Title has reportedly found their next project by way of adapting the satirical book My Sister The Serial Killer into a movie.

The novel, written by novelist Oyinkan Braithwaite, tells the tale of a Nigerian woman whose younger sister seems to have a mild obsession with killing all of her boyfriends. Braithwaite, who graduated from the Creative Writing and Law program at Kingston University, has previously worked as an assistant editor at Nigerian publishing house Kachifo and in 2016, she was a finalist for the Commonwealth Short Story Prize. My Sister The Serial Killer is her first book.


A synoposis for the story can be seen below:

“Korede is bitter. How could she not be? Her sister, Ayoola, is many things: the favorite child, the beautiful one, possibly sociopathic. And now Ayoola’s third boyfriend in a row is dead. Korede’s practicality is the sisters’ saving grace. She knows the best solutions for cleaning blood, the trunk of her car is big enough for a body, and she keeps Ayoola from posting pictures of her dinner to Instagram when she should be mourning her “missing” boyfriend. Not that she gets any credit. A kind, handsome doctor at the hospital where Korede works, is the bright spot in her life. She dreams of the day when he will realize they’re perfect for each other. But one day Ayoola shows up to the hospital uninvited and he takes notice. When he asks Korede for Ayoola’s phone number, she must reckon with what her sister has become and what she will do about it.”

The book is apparently going to hit the states later this year thanks to U.S. publisher Doubleday and the Atlantic will publish it in the UK. Aitken Alexander is currently rumored to be handling the screen rights while Big Talk – whose last collaboration with Working Title brought about Baby Driver – is set to produce.
