Who is Patrick Fitzgerald?

The New York Times offers an interesting description of the man who is at the center of the Plame Affair investigation and holds all the cards very close to his vest.

Their description is "Leak Prosecutor Is Called Exacting and Apolitical." He is a man who is a workaholic and will go where the evidence takes him. He is unlikely to be deterred by potential repercussions of any indictments. These characteristics, the ending of the term of the Grand Jury October 28, and his ability to keep his office from leaking have led to the flurry predictions what he will do, from simply walking away and saying he found nothing indictable up to possibly indicting the Vice President for crimes he has committed.
