Those early experiences launched Raab on a legendary journalism track in which he scrutinized the Mafia, its clannish structure, rituals and roguish personalities as a reporter and editor at the World Telegram & Sun, NBC News, WNET and the New York Times. He became—like Jerry Capeci at the New York Post and Anthony M. DeStefano at Newsday—one of the Mob’s chief chroniclers.
In 2005, Raab turned the wisdom he’d accumulated over 40 years of writing about the Mafia into the New York Times bestseller Five Families: The Rise, Decline, and Resurgence of America’s Most Powerful Mafia Empires; reissued in paperback in 2016, Five Families once again hit the bestseller list.
