The Nutshell (1963)

John Cater: Disco

Quotes 

• Disco : Early this morning, someone got in here without authority, used the correct sequence pattern on these, and copied Big Ben.

  Catherine Gale : What is it?

  Disco : The name means: Bilateral Infiltration, Great Britain, Europe and North America. It is a document which lists all known double agents on both sides in the cold war. In hostile hands, it can deal a death blow to every allied agent operating on the wrong side of the iron curtain. Needless to say, if we fail to get it back, we face a large scale national disaster. And that's only half the problem. The other half is worse.
