From Corrente, on the revelation that Novak’s second source “high administration official” (besides Rove) was Scooter Libby, Dick Cheney’s chief of staff:

You know, this whole thing reminds of that great old Agatha Christie novel, Murder on the Orient Express. The whodunnit is totally confusing, clues pointing every which way and cancelling each other out, until Hercule Poirot figures out that the reason the clues could only make sense if they were all in on it, is that, indeed, they were all in on it.

I doubt it, but it’s nice to dream.  (Hope I didn’t ruin the book/movie for y’all!)
