FILE - This July 13, 2011, photo made available on the International Security Assistance Force's Flickr website shows the former Commander of International Security Assistance Force and U.S. Forces-Afghanistan Gen. Davis Petraeus, left, shaking hands with Paula Broadwell, co-author of his biography "All In: The Education of General David Petraeus." The affair between retired Army Gen. David Patraeus and author Paula Broadwell is but an extreme example of the love/hate history between biographers and their subjects. (AP Photo/ISAF, file)
