Robert Eringer's book, Ruse — Undercover with FBI counterintelligence (2007), is a hell of a suspenseful ride! A good patriotic hustler, who risks his life for country and justice, Eringer goes after traitor Edward Lee Howard in post-communist Russia, assists in the capture of notorious killer Ira Einhorn in France, hoodwinks die-hard communist KGB Chairman Vladimir Kryuchkov in Moscow, and plays the Great Game skillfully with Cuban Intelligence in Washington and Havana.
The Astounding Case of Soviet Defection Deception
In "Alexander Orlov: The FBI's KGB General" (2002), former FBI agent Edward Gazur tries to prove the impossible that KGB Gen. Alexander Orlov was a true defector, a man who switched allegiances from the Soviet Union to America and repudiated international communism.
Gazur ardently believes that Orlov, who became his friend and whom he ultimately came to love as a father figure, genuinely cooperated with the FBI and the CIA. This (his own) book unfortunately proves quite the opposite.
