But they said they could bear anything as long as their children grew up to lead happy and fulfilled lives.

Carla had always taken it for granted that she would spend her life making the world a better place, as her parents had. She did not know whether she would have followed her father into politics or her mother into journalism, but both were out of the question now.

What else was she to do, under a government that prized ruthlessness and brutality above all else? Her brother had given her the clue. Doctors made the world a better place regardless of the government. So she had made it her ambition to go to medical school. She had studied harder than any other girl in her class, and she had passed every exam with top marks, especially the sciences. She was better qualified than her brother to win a scholarship.

‘There are no girls at all in my year,’ Erik said. He sounded grumpy. Carla thought he disliked the idea of her following in his footsteps. Their parents were proud of his achievements, despite his repellent politics. Perhaps he was afraid of being outshone.

Carla said: ‘All my grades are better than yours: biology, chemistry, maths—’

‘All right, all right.’

‘And the scholarship is available to female students, in principle – I checked.’

Their mother came in at the end of this exchange, dressed in a grey watered-silk bathrobe with the cord doubled around her narrow waist. ‘They should follow their own rules,’ she said. ‘This is Germany, after all.’ Mother said she loved her adopted country, and perhaps she did, but since the coming of the Nazis she had taken to making wearily ironic remarks.

Carla dipped bread into milky coffee. ‘How will you feel, Mother, if England attacks Germany?’

‘Miserably unhappy, as I felt last time,’ she replied. ‘I was married to your father throughout the Great War, and every day for more than four years I was terrified that he would be killed.’

Erik said in a challenging tone: ‘But whose side will you take?’

‘I’m German,’ she said. ‘I married for better or worse. Of course, we never foresaw anything as wicked and oppressive as this Nazi regime. No one did.’ Erik grunted in protest and she ignored him. ‘But a vow is a vow, and, anyway, I love your father.’

Carla said: ‘We’re not at war yet.’

‘Not quite,’ said Mother. ‘If the Poles have any sense, they will back down and give Hitler what he asks for.’

‘They should,’ said Erik. ‘Germany is strong now. We can take what we want, whether they like it or not.’

Mother rolled her eyes. ‘God spare us.’

A car horn sounded outside. Carla smiled. A minute later her friend Frieda Franck entered the kitchen. She was going to accompany Carla to the interview, just to give moral support. She, too, was dressed in sober-schoolgirl fashion, though she, unlike Carla, had a wardrobe full of stylish clothes.

She was followed in by her older brother. Carla thought Werner Franck was wonderful. Unlike so many handsome boys he was kind and thoughtful and funny. He had once been very left wing, but all that seemed to have faded away, and he was non-political now. He had had a string of beautiful and stylish girlfriends. If Carla had known how to flirt she would have started with him.
