Peter FitzSimons' Gallipoli

At the end of the 1980s, the Soviet army is being universally modernised, observed closely by western military intelligence in East Germany. Weapons-scouts in the field are constantly on duty, as are agents in high command or in intelligence service stations, for instance in the autumn of 1983, as NATO is practising new procedures of nuclear release. Moscow is concerned the exercise could be the beginning of a nuclear first strike. It takes a double agent to clear up this dangerous misunderstanding.

During the Cold War, tensions between East and West mount alarmingly. In consequence, western intelligence services shift their focus on East Germany as the Warsaw Pact's major deployment zone. Nowhere else did western services get as close to Soviet military equipment. Their prime targets are missiles, nuclear depots and airbases. At the same time, the KGB, as well as Soviet military intelligence, were sending their spies to reconnoitre NATO forces in the West. The game of spies was in full swing.
