They then took me to the police station where several secret police officials took turns In interrogating me for hours. In the morning they let me go. but posted a guard in front of the house. In the afternoon they would bring an interpreter to have my visa translated. they said. We had to act fast now. Early in the morning I slipped past the guard in front of the house. and bicycled to the Oranienburg police station. I went to see an officer whom I knew to be particularly stupid. and asked him for an extension of my Russian visa. I loved life in the Red world. I told him warmly and wanted to stay. As expected. he told me gruffly that only the Russians themselves in Berlin could give such a visa. I pointed out to him the fact that I needed some kind of identification to pass the check point before entering Berlin. At this point.
