A former research assistant for Bob Woodward is hired to help Ben Bradlee work on another book, and discovers that the former Washington Post managing editor still has unresolved questions from the Watergate era:

Did that potted [plant] incident ever happen? … and meeting in some garage. One meeting in the garage? Fifty meetings in the garage? I don’t know how many meetings in the garage … There’s a residual fear in my soul that that isn’t quite straight.

“I read it over a few times to make sure. Did Ben really have doubts about the Deep Throat story, as it had been passed down from newsroom to book to film to history?”
