Family Betrayal

Agent Sonya, MI5 and the Kuczynski Network

David Burke
Robert and Berta Kuczynski arrived in Britain as refugees from Nazi Germany but they and their six children – including Ursula, codenamed Sonya – were already working for the KGB. Drawing on newly declassified documents, this investigation reveals how they infiltrated government and the security service to pass nuclear secrets to the Soviets, and their association with Burgess, Blunt and Maclean.
