Episode two hundred seventeen - part four

Elizabeth Winthrop Alsop grew up the daughter of war hero and journalist Stewart Alsop III, but her mother Tish Alsop had been a hero in her own right. Elizabeth chats with us about discovering her quiet mother's secret history as a decoding agent for MI5 -- and how this granted her a deep relationship with her mother later in life, only to care for Tish as she succumbed to dementia in her later years.
