In addition could I respectfully offer Bletchley Park, Alan Turing, The Famous 5, or the Cambridge Blues, AKA the Cambridge Spy Ring. Blunt, Cairncross, Philby, Burgess and Maclean. of MI5, MI6, Foreign Office. GCHQ Geoffrey Prime, Katharine Gunn. Actually, the more one looks, the more one finds...What would we do without them.. :-).
P.S. How about Mata Hari?
