Tereza can not stop thinking that the tall stranger is part of the secret police. When Tereza first arrived at his flat and found the copy of Oedipus, he went behind the curtain for coffee, but when he came back, he didn’t bring any. She knows more than ever that it was a trap. Just the other day she laughed at Tomas’s Czech radio program because they all failed to see that they are living in a concentration camp. So is Tereza.
This, too, highlights the oppression of the Czech people by the Russians. There is no privacy at all, not during phone conversations and not even during an intimate moment between two people. The Russians have completely infiltrated Tereza’s life and existence in more ways than one.
