"Melita Norwood"

"Before she was catapulted into the public eye in September 1999, Melita Norwood lived in complete obscurity, a secretary who had worked at the Non-Ferrous Metals Research Association in London and was known to her neighbours as a “lovely old lady” who produced homemade jam. Yet Norwood was one of the Soviet Union’s longest-serving spies and the most important British female agent to be recruited by the KGB."

This name has been stuck with me since 1999, if often pops back into my head on a weekly basis. I guess because there is something nice about the sound of the name, plus it's a great story of how sweet little old ladies are not always what they seem...
