In 1856, a young woman entered the Pinkerton Detective Agency's offices at 80 Washington Street in Chicago, Illinois, looking for employment. According to his own accounts, Pinkerton politely told her he didn’t need a cleaner or a secretary, but she insisted she wasn’t interested in a traditional woman’s role. She believed the detective service needed her as an agent. After considering her compelling arguments, Allan Pinkerton hired her as his first female operative. This is the story of Kate Warne, the first female Pinkerton detective. Listen carefully, because this story is full of hard to believe details.
