Mahmood Mattan is a fixture in Cardiff’s Tiger Bay, 1952, which bustles with Somali and West Indian sailors, Maltese businessmen and Jewish families. He is a father, chancer, some-time petty thief. He is many things, in fact, but he is not a murderer. So when a shopkeeper is brutally killed and all eyes fall on him, Mahmood isn’t too worried. But his becomes a fight for life.
