Sadie, Niki, Poppy, and Kate—sexy, confident, and wealthy women on the surface—are all trapped in loveless and sometimes violent marriages to four of the most feared gangsters in London. For years their lives of idle luxury, shopping, and lunching have come at the price of staying loyally behind the scenes as their men rule the East End criminal underworld with violence and terror. But when their husbands' positions of power are jeopardized, they seize the opportunity to fight back and try to beat the men at their own game.
