"The thrilling never-before-told story of Agent Sniper, one of the Cold War's most effective counter-agents Michal Goleniewski, cover name Sniper, was one of the most important spies of the early Cold War. For two and a half years at the end of the 1950s, as a Lt. Colonel at the top of Poland's espionage service, he smuggled more than 5,000 top-secret Soviet bloc intelligence and military documents, as well as 160 rolls of microfilm, out from behind the Iron Curtain. In January 1961, he abandoned his wife and children and made a dramatic defection across divided Berlin with his East German mistress to the safety of American territory. There, he exposed more than 1600 Soviet bloc agents operating undercover in the West-more than any single spy in history. The CIA called Goleniewski "one of the West's most valuable counterintelligence sources," but in late 1963, he was abandoned by the US government because of a split in the agency over questions about his mental stability and his trustworthiness. Goleniewski bears some of the blame for his troubled legacy. He made baseless assertions about his record, notably that he was the first to expose Kim Philby. He also bizarrely claimed to be Tsarevich Aleksei Romanoff, heir to the Russian Throne who had miraculously survived the 1918 massacre of his family. For more than fifty years, American and British intelligence services have sought to erase Goleniewski from the history of Cold War espionage. The vast bulk of his once-substantial CIA and MI5 files remain closed. Only fragments of his material crop up in the de-classified dossiers on the KGB spies he exposed or the memoirs of CIA officers who dealt with him. A never-before-told story, Tim Tate's Agent Sniper is a crackling page-turner that takes readers back to the post-war world and a time when no one was what they seemed"--
