The wife of Billy Kimber was made a widow by the hand of Thomas Shelby. He had seen her at the races and took a liking to her. Her name was Josie Kimber nee Lee. He had married her to keep the Lees on side but they saw the way he treated her so they stayed not out of loyalty to him, but to her. When Tommy Shelby showed up they thought they would be unable to protect her anymore, but then he came to them with a proposal. Marry off a Lee girl to a Shelby. But not just one. Two. To insure loyalty. From which side no one is quite sure.
