Via Parenthetical comes this article about a side of Roald Dahl I never knew about:
He is known to the world as the author of bestselling children’s books such as Charlie and the Chocolate Factory and James and the Giant Peach. Yet before he became a successful writer, Roald Dahl had a very different reputation – as the sexiest British spy in America.
I agree with the commenter who said this screams for a film adaptation. Not sure who I'd cast, though.
A minor journalistic quibble: the author of the article never actually gives the title of Ms. Conant's book. (It's The Irregulars: Roald Dahl and the British Spy Ring in Wartime Washington.)
