"For over fifty years the CIA has closely guarded the identity of the first agent killed in the line of duty - the unnamed First Star on the outfit's Wall of Honor. That agent was Douglas Mackiernan. His unprecedented atomic intelligence operations helped shape both Central Asia and the CIA as we know them today. His work remains so sensitive that the Agency, even now, will neither confirm nor deny his existence.

A riveting expose of international intrigue, Into Tibet reveals the extraordinary still-classified missions that sent Mackiernan and his partner, Frank Bessac, into the heart of the Cold War."--BOOK JACKET.
