Alistair MacLean's Death Train

Three agents from the United Nations Anti-Crime Organization had a mind-boggling mission: to find out who stole six kegs of plutonium from a European train. But that wasn't the end of the case. It turned out that only five kegs contained plutonium. The sixth held something even worse. Just as John Gardner has continued the work of Ian Fleming, Alastair MacNeill now maintains the excitement of Alistair Maclean.
