...Russian-run uranium mines in southeastern Germany. Allied intelligence would not confirm, but did not deny, that the new Soviet "defector of colonel's rank" is Astakhov. If he is, the West has found a source of atomic intelligence as useful as Britain's missing Bruno Pontecorvo presumably is to the Russians...
...British call "hysterical" if displayed by Americans. Police on two continents, including Scotland Yard, launched a gigantic man hunt for Donald Duart MacLean and Guy Francis de Moncy Burgess. Everyone recalled the case of Atom Spy Klaus Fuchs and the flight of Britain's Atom Scientist Bruno Pontecorvo behind the Iron Curtain last year.

Pontecorvo was an expert on nuclear reactors, the devices which are needed to make plutonium...

The Pontecorvos picked up a taxicab and sped off. After that, no trace...
