In the final part of our spine-tingling new series by top espionage writer Ben Macintyre, we reveal how the net of the security services began to close around Soviet superspy Agent Sonya. However, thanks to the efforts of a comically inept MI5 surveillance chief, she was able to evade detention and prepared to flee back to the East . . .
Resolute: Ursula Kuczynski aka Agent Sonya lived till she was 93
The picturesque hamlet of Great Rollright in the heart of the north Oxfordshire Cotswolds was remote and exceedingly quiet when Ursula Beurton moved there with her three children in 1945, just after the end of World War II.
Yesterday, in the first part of a spine-tingling new series by top espionage writer BEN MACINTYRE, we revealed how a sex-mad Soviet agent posed as a Cotswolds housewife to run a cabal of Communist spies from her cottage.
Here, we tell how she delighted her masters and even Stalin himself with her access to the very heart of Britain s top-secret atom bomb research.
When housewife and mother Ursula Beurton in reality, Major Ursula Kuczynski of the Red Army, a Soviet spy who had conducted espionage operations in China, Poland and Switzerland landed at Liverpool on a ship from Spain in early 1941, MI5 already had its suspicions about her.
