Americana - 21/02/2010

Americana goes underground, for Washington Confidential. Kevin Connolly talks to Pulitzer Prize-winning author Garry Wills about his new book, Bomb Power, and the theory that getting the bomb - and preventing others from getting it afterwards - has turned America into a secretive behemoth. Kevin takes a tour of Washington's most significant espionage locales with spook-watcher Eamon Javers, and ponders the evolution of an industry which has been the secret beating heart of this town since intelligence services first came into existence in America. Kevin dons his smoking jacket and sits down with Ed Walker, the host of Sunday night detective serials on American radio, the Big Broadcast.
