51 Birch Street is the first-person account of a family's life-changing events. A few months after his mother's sudden death from pneumonia, Doug Block's 83-year-old father, Mike, calls him to announce that he’s moving to Florida to live with "Kitty", his secretary from 40 years before. Always close to his mother and equally distant from his father, Doug and his two older sisters were shocked and suspicious.
