This is an investigation into the fate of British prisoners of war liberated from prison camps by the Soviets at the end of World War II and after the Korean War. With Boris Yeltsin admitting that some of them may still be alive in prisons in the ex-Soviet Union, Cawthorne has travelled to Siberia to follow their trail. The book also seeks to explain why the British Government tried to cover-up the truth by denying the existence of the missing men. Nigel Cawthorne has also written The Bamboo Cage, about the fate of US prisoners of war.
