n the wake of CIA Director David Petraeus' surprising resignation on Friday, Slate's Fred Kaplan reported that "the woman with whom  Gen. David Petraeus was having an affair is Paula Broadwell, the author of a recent hagiographic book about him, All In: The Education of General David Petraeus."

Kaplan continues:

It had long been rumored that something was going on between Petraeus and Broadwell. Her book, co-written with Vernon Loeb, is widely regarded as a valentine to the general. When she was embedded with him in Afghanistan, they went on frequent five-mile runs together. But Petraeus went on five-mile runs with many reporters, and few people who knew him took the rumors seriously. In his personal life, he’s always been seen as a straight shooter, a square. Few could have imagined that his end would come as the result of a morals scandal.
