Two influential families are embroiled in a web of deceit, leading to espionage and murder. The thriller begins in 1961 during the Cold War and centres on the newly constructed Berlin Wall, ruthlessly controlled by the Ministry of State Security, otherwise known as Stasi. John Groves, aided by Hans Von Klaus, seeks to rescue Hans' elder brother Dieter from the East German city of Leipzig and return him to the safety of the West. Suspected of being a dissident by Stasi, torture and imprisonment await the hapless former West German. Can Dieter be saved from the clutches of this highly effective secret police organisation, or will it end in disaster?
