In the early 1900s police were stymied by a series of murders of Italian grocers and fruit vendors in midwest America. Witnesses refused to cooperate, which made the crimes impossible to solve. Enter the United States Postal Service. Postal Inspector Frank Oldfield finds a man willing to testify, and suddenly the organization is knee-deep in a massive investigation which leads them to one of the first crime rings of Sicilian gangsters in American history. For the first time, law enforcement agencies realize that an organized mafia (known as the Black Hand) exists in the United States. My guests are William Oldfield and Victoria Bruce, authors of **Inspector Oldfield and the Black Hand Society**, and share some of the most interesting details from their book on this episode.
