Bob Woodward "flashes a glimpse of what he knows, shaded in a largely negative light, with the hint of more to come..."

"... setting up a series of prisoner's dilemmas in which each prospective source faces a choice: Do you cooperate and elaborate in return (you hope) for learning more and earning a better portrayal — for your boss and yourself? Or do you call his bluff by walking away in the hope that your reticence will make the final product less authoritative and therefore less damaging? If no one talks, there is no book. But someone — then everyone — always talks."

George Stephanopolos tells how Bob Woodward gets his access to the White House.
