Just finished Seymour Hersh's Chain of Command.
It's a stunning piece of work, a sober and patient unravelling of the failures and lies that led to the war in Iraq and the Abu Ghraib prison scandal.
Hersh collects whispers and secret conversations from spooks, diplomats and officials and weaves them into a devastating narrative.
Yet even after more than 400 pages of dogged prodding and probing, Hersh admits he doesn't have all the answers. "There is so much about this presidency that we don't know, and may never learn," he says.
If you're still short of a Christmas present, I highly recommend it.
