Matt Crawford speaks with author Jeffrey Simon about his book, The Bulldog Detective: William J. Flynn and America's First War Against the Mafia, Spies, and Terrorists. Who was William J. Flynn? At the forefront of crime fighting as a member then Chief of the Secret Service, Deputy Commissioner in the NYPD and director of the Bureau of Investigation (the forerunner of the FBI) this man chased down corruption, spies, the Mafia and terrorists and the turn of the 20th century. Why then so do few know his name. That is a wrong that Simon looks to right in this detailed and exciting read that proves history is anything but boring.
