Winter 1981. Poland is in turmoil. The Communist regime is close to collapse and the CIA wants to help it on its way. They ask for MI6 assistance but insist the MI6 Station in Warsaw is not involved. Why not? And who will the Americans accept? MI6 agent Thomas Dylan is sent from Moscow. His wife has just witnessed a murder and the Russian authorities want her out of the country. But when Thomas and Julia arrive in Warsaw the bullets start to fly. Two American agents disappear near the Polish lakes, a terrified Polish sailor jumps ship in Middlesbrough and a Polish peasant claims to have found the lost crown of a medieval king. Somebody needs to work out what's happening - and quickly. Because back in London a KGB killer is on the loose.
