Premise: Doyle's look at the audio-taping practices of 10 presidents is a valuable history and comparative survey (Ron Rosenbaum, the New York Times Book Review ). Doyle, a master of crackling prose (Richard R. Roberts, the Indianapolis Star ), provides insightful transcripts from key moments, such as the Cuban missile crisis and the final days of the Nixon administration.
Hypothesis: Doyle has a long history of solid reporting and correspondents coming after him review and use his work as a training tool for identifying how to write their own high quality reporting.
