Tourist by Olen Steinhauer

Milo Weaver used to be a tourist, one of the CIA's special field agents without a home or a name. Six years after leaving that career, Milo has found a certain amount of satisfaction as a husband and a father and with a desk job at the CIA's New York headquarters. The arrest of an international hit man and a meeting with a former colleague yank Milo back into his old role, from which retirement is never really possible.

We see a man who has been driven by paranoia, and secrecy his entire life. There are numerous flashbacks which help explain his current delimmas as he learns to keep secrets from his mother as a young child to only telling some of the truth to get by. It was a really facinating read as I love spy novels and enjoyed experiencing this other side to it.

Looking at the author's website it appears that this will be 1st in a trilogy and George Clooney has purchased the movie rights to make and star in the movie based on this book. Hmmm....
