Thriller writers don't get much better than Charles McCarry (latest, Secret Lovers) and Robert Littell (I'm reading Legends—about a former CIA officer who becomes confused about who he is. Apt reading in "Scooter" week?).
Highly recommended, a surprising "page turner": The President, the Pope, and the Prime Minister: Three Who Changed the World, by John O'Sullivan. Obviously about Reagan, John Paul II, and Thatcher. It is doing no less than changing my perspective on three decades of my life.
