As most of us have long suspected, the man who told Novak about Valerie Plame was Richard Armitage, Colin Powell's deputy at the State Department and, with his boss, an assiduous underminer of the president's war policy.
(His and Powell's—and George Tenet's—fingerprints are all over Bob Woodward's "insider" accounts of post-9/11 policy planning, which helps clear up another nonmystery: Woodward's revelation several months ago that he had known all along about the Wilson-Plame connection and considered it to be no big deal.)
