Bloodmoney

I enjoyed David Ignatius's Bloodmoney, although probably more because it's a while since I've read a good modern espionage novel than because it's one of the greats.  Not that any of it is actually bad, and I thought Ignatius's villain is an interesting character.  (Also, his motivation at the end was very well done).

But it also doesn't really have the sorts of high notes that characterize, say, The Spy Who Came in from the Cold, with its complex characters and narrative reverses.
