Afterward he had apologized to Rebecca for losing his temper. She had been scared by his vindictiveness, and had come close to ending their relationship. But he had explained that he had not been his normal self, due to pressure at work, and she had believed him. Her faith had been justified: he had never done such a thing again.

When they had been dating for a year, and sleeping together most weekends for six months, Rebecca wondered why he did not ask her to marry him. They were not kids: she had then been twenty-eight, he thirty-three. So she had proposed to him. He had been startled, but said yes.

Now he pulled up outside her school. It was a modern building, and well equipped: the Communists were serious about education. Outside the gates, five or six older boys were standing under a tree, smoking cigarettes. Ignoring their stares, Rebecca kissed Hans on the lips. Then she got out.

The boys greeted her politely, but she felt their yearning adolescent eyes on her figure as she splashed through the puddles in the school yard.

Rebecca came from a political family. Her grandfather had been a Social Democrat member of the Reichstag, the national parliament, until Hitler came to power. Her mother had been a city councilor, also for the Social Democrats, during East Berlin’s brief postwar period of democracy. But East Germany was a Communist tyranny now, and Rebecca saw no point in engaging in politics. So she channeled her idealism into teaching, and hoped that the next generation would be less dogmatic, more compassionate, smarter.

In the staff room she checked the emergency timetable on the notice board. Most of her classes were doubled today, two groups of pupils crammed into one room. Her subject was Russian, but she also had to teach an English class. She did not speak English, though she had picked up a smattering from her British grandmother, Maud, still feisty at seventy.

This was the second time Rebecca had been asked to teach an English class, and she began to think about a text. The first time, she had used a leaflet handed out to American soldiers, telling them how to get on with Germans: the pupils had found it hilarious, and they had learned a lot too. Today perhaps she would write on the blackboard the words of a song they knew, such as “The Twist”—played all the time on American Forces Network radio—and get them to translate it into German. It would not be a conventional lesson, but it was the best she could do.

The school was desperately short of teachers because half the staff had emigrated to West Germany, where salaries were three hundred marks a month higher and people were free. The story was the same in most schools in East Germany. And it was not just teachers. Doctors could double their earnings by moving west. Rebecca’s mother, Carla, was head of nursing at a large East Berlin hospital, and she was tearing her hair out at the scarcity of both nurses and doctors. The story was the same in industry and even the armed forces. It was a national crisis.
