Being a Shelby could be hard, two children were about to learn this. These two children however belonged to the ruthless gangster, Thomas Shelby. After the war Thomas heart had become cold and his eyes empty. He was at a loss. More cold and ruthless than ever before. He had changed, but who hadn't? Two children in need of a home, far away from their father and real family. Two children, that had never had care or been loved before were about to be shown what it was like to be a part of a family that would die for them but would they be able to learn to do the same? So the only question that remains is whether or not they can adapt to the ways of the Shelby's and can they adjust to the madness that seems to follow the Shelby's?
