My Sister, The Serial Killer

Oyinkan Braithwaite, Atlantic Books, £12.99

Beautiful Ayoola has stabbed her boyfriend. He is the third she’s killed. Her conscientious, loyal sister Korede is well prepared for the clean-up job.

But she’s not prepared for Ayoola taking an interest in her rather attractive doctor colleague.

The writing is as sharp as the killer’s blade, with

Braithwaite winding up the uneasiness.

OUR VERDICT 8/10
