In 1952, Somali seaman Mahmood Mattan, convicted of the murder of a local shopkeeper, became the last man to be hanged in Cardiff. Forty-five years later, his conviction was quashed. In The Fortune Men, the British-Somali writer Nadifa Mohamed takes this true story and gives it a novel treatment. Amongst the bustling, multiracial town of Tiger Bay, we meet Mattan, a man of quiet dignity and anger, and the corrupt and racist police who frame him for murder. Mohamed also paints a sympathetic portrait of the murder victim, here renamed Violet Volacki. Nadifa Mohamed is speaking to Claire Nichols.
