John Dean's e-book is a thrilling Watergate detective story, with new evidence on the identity of history's most elusive news source --------------------------------- Deep Throat was the shadowy source who haunts the pages and scenes of "All the President's Men." He provided Woodward and Bernstein with clues that helped break open the Watergate story and ultimately bring down a president. But who was he? John Dean, the former Nixon White House counsel whose crucial testimony ended the Watergate cover-up and changed history, is determined to discover the identity of his former colleague -- "the one person," he writes, "who will go into history outranking me on Richard Nixon's final enemies list." "Unmasking Deep Throat" assembles all the clues in one place and adds crucial new evidence Dean has uncovered in the archives and drawn together from his own recollections. The book significantly narrows the roster of Throat "suspects," zeroing in on the small handful of remaining possibilities.
