RUSSIA'S PENETRATION OF THE FREE WORLDS DEFENCES

In this extraordinary volume, first published in 1981, British journalist Chapman Pincher dissected the whole of the Soviet penetration of the western world during the twentieth century, helped unmask the Cambridge Five, and outlined his suspicions that former MI5 chief Peter Hollis was a Soviet super-spy at the heart of a ring of double-agents, poisoning the Secret Intelligence Service from within.

Chapman Pincher began a career in journalism, joining the Daily Express as a science and defense correspondent at the end of the Second World War. He was regarded as one of the UK's finest investigative reporters of the twentieth century. He died in 2014.
