Infamous Soviet Atom Spies who make up Red Joan's characters: This is exactly why I wanted a first class science graduate as an assistant. Not a pretty face. I mean, of course you're not not a pretty face. (Melita Norwood -- a secretary in the British Non-Ferrous Metals Research Association, linked to the Woolwich Arsenal spy ring of 1938 and in wartime to "Tube Alloys" program.) === Oh, well, I'm sure you've already thought of this but... a centrifugal force could separate of the two isotopes. (Klaus Fuchs — the German-born British theoretical physicist who worked with the British delegation at Los Alamos during the Manhattan Project on the processes for separating isotopes of uranium.) === I can't stop Sonya doing anything. Well, you run all the op, right? My dear girl, Sonya does. (Ursula Kuczynski AKA Ruth Werner, code name Sonya, handler of nuclear scientist Klaus Fuchs.)
