Katherine Irma Mayfair (previously Davis) is one of the main and titular characters of Desperate Housewives. A former victim of domestic abuse, perpetrated by her first husband, a corrupt policeman, Katherine moved to Wisteria Lane hoping to get away from her rough lifestyle and be happy. However, unfortunate circumstances led her to pack and leave suddenly, only to return several years later with a new family in tow and a big secret weighing heavily on her. Katherine rivaled Bree Van de Kamp for the title of perfect home fairy, and soon moved comfortably into the position of scheming vixen when it came to going about making her ends meet.
