NEW YORK - It was a night in early November during the infancy of the Cold War when the anti-communist dissidents were hustled through a garden and across a gully to a vehicle on a dark, deserted road in Budapest. They hid in four large crates for their perilous journey.

Four roadblocks stood between them and freedom.

What Zoltan Pfeiffer, a top political figure opposed to Soviet occupation, his wife and 5-year-old daughter did not know as they were whisked out of Hungary in 1947 was that their driver, James McCargar, was a covert agent for one of America's most secretive espionage agencies, known simply as the Pond.
