Xpd Mass Market Paperback – April 12, 1983 by Len Deighton (Author)
It is 1979. A stolen World War II document kept secret since then is about to surface, propelling the most ruthless secret agents of Great Britain, America, Germany, and the Soviet Union into a desperate battle of wits and violence. Anyone who learns of the paper must die, his file stamped Expedient Demise, or . . . XPD.
