- State Department Official: Will we in this nation ever learn the difference between tolerance and stupidity?
- Instructor: Ever since the World War, we've been trying to perfect a machine that would encode and decode automatically. Well, here it is.
- Instructor: The machine offers a variety of 2,372 entirely original codes. That would give an inquisitive outsider 2,371 chances of being wrong, even if he had the machine to work with.
- Student: Does this machine take the place of former code books?
- Instructor: Oh, not at all.
- Dr. Anton Rader: One more stop before the border. Are you nervous?
- Brenda Ballard: No.

- Dr. Anton Rader: You must have had a very poor opinion of our intelligence if you thought we were takin in by you - not for one moment, Mrs. Corvall. You thought you were very clever, didn't you? We know America has no counterespionage. In a few minutes, we shall be in another country and then... well, we have ways of dealing with people like you. Not very nice ways, but they're surprisingly effective.
