Intelligence officers and investigative journalists both depend on clandestine sources to divulge secrets. But why do people betray a trust? Peter interviews veteran journalist Max Holland about his new book, Leak, which probes the mind and motivations of one of the most famous clandestine sources in American history: Deep Throat. Hear why Mark Felt, the Deputy Director of the FBI, betrayed President Nixon by leaking to the Washington Post and Time about Watergate. Were Felt’s motives patriotic or self-serving…or both?
