Many people know All the President's Men as a film: a hit movie about the two young reporters who cracked the Watergate conspiracy. It's the only blockbuster that centers on two guys making phone calls, organizing paper notes and meeting a source called Deep Throat in a parking garage.
But before the movie, there was a book, which came out 40 years ago this month. In it, reporters Bob Woodward and Carl Bernstein tell the story of how they uncovered the scandal.
It all started in the Watergate hotel and office complex in Washington.
