The Iron Curtain has clanged down across post-war Europe, and the Red Army is entrenched in the very heart of Germany.

Tyrannical communist rule based on state terror begins as the repressive regime launches a campaign of international espionage. Working against all odds, British lieutenant Ben Fletcher goes undercover to level the score and to gain vital nuclear intelligence for the West. Pursuing the same goal, ruthless Stalinist authorities are prepared to pull out all the stops to wreck his mission.

Decades later, Detective-Sergeant Lillian Boyd faces high stakes. A tragically unsolved roadside hit-and-run death spirals into an urgent quest to expose an insidious nest of foreign spies, orchestrated by an ambitious spymaster. Their aim - an audacious coup against an unsuspecting prime minister. Will she foil the carefully-crafted plot?

The past may just hold the answer Lillian needs to thwart a conspiracy that threatens to change the balance of political power forever.
