Nothing about the romance between Nancy Hatch Dupree and Louis Dupree was what you'd call typical. For starters, there were the lovers themselves. Louis was a foul-mouthed paratrooper turned swashbuckling archaeologist. Nancy was a witty travel writer and the wife of a CIA station chief on the ragged frontier of the Cold War. Then there was the place and time: Kabul, Afghanistan in the 1960s, a heady and short-lived milieu of conniving spies, future mujahideen, and cocktail-swilling cosmopolitans.
