The Untold Story of Agent Sniper: The Cold War's Most Effective Counter-Agent
Agent Sniper is the thrilling, never-before-told story of Michal Goleniewski, one of the most important spies of the early Cold War. As a Lieutenant Colonel in Poland's espionage service, Goleniewski smuggled thousands of top-secret Soviet bloc documents and microfilm from behind the Iron Curtain. In January 1961, he made a dramatic defection to American territory with his East German mistress, exposing more than 1,600 Soviet bloc agents in the West—more than any single spy in history.
The CIA called Goleniewski "one of the West's most valuable counterintelligence sources," but he was later abandoned by the US government due to internal agency conflicts and questions about his mental stability and trustworthiness. Goleniewski made some baseless assertions about his record and bizarrely claimed to be Tsarevich Aleksei Romanoff, the heir to the Russian Throne who had supposedly survived the 1918 massacre of his family.
For over fifty years, American and British intelligence services have sought to erase Goleniewski from Cold War espionage history, with the vast majority of his CIA and MI5 files remaining closed. However, his newly-released Polish intelligence file reveals the remarkable extent of his espionage on behalf of the West.
Agent Sniper is a crackling page-turner that brings together love, loyalty, courage, betrayal, greed, and ultimately, insanity. Tim Tate takes readers back to the post-war world, where no one was quite what they seemed in this gripping true story of Cold War espionage.
