‘Apparently the girl was a singer and often took part in the BdM, the League of German Girls, evening radio programme. On the night of her disappearance she had attended the Funk-turm Studios on Masuren-Strasse, and sang a solo — the Hitler Youth song — at seven o’clock. The girl’s father works as an engineer at the Arado Aircraft Works in Brandenburg-Neuendorf, and was supposed to pick her up on his way home, at eight o‘clock. But the car had a flat tyre and he was twenty minutes late. By the time he got to the studios Christiane was nowhere to be seen and, supposing that she had gone home on her own, he drove back to Spandau. When by 9.30 she still hadn’t arrived, and having contacted her closest friends, he called the police.’

Korsch glanced up at Illmann, and then myself. He smoothed the vain little moustache and turned to the next page in the file that lay open in front of him.

‘Zarah Lischka,’ he read. ‘Aged sixteen, of German parents. Disappeared 6 July 1938, body found I August, down a drain in the Tiergarten, close to the Siegessaule. The family lived in Antonstrasse, Wedding. The father works at the slaughterhouse on Landsbergerallee. The girl’s mother sent her down to some shops located on Lindowerstrasse, close to the S-Rahn station. The shopkeeper remembers serving her. She bought some cigarettes, although neither one of her parents smokes, some Blueband and a loaf of bread. Then she went to the pharmacy next door. The owner also remembers her. She bought some Schwarzkopf Extra Blonde hair colourant.’

Sixty out of every hundred German girls use it, I told myself almost automatically. It was funny the sort of junk I was remembering these days. I don’t think I could have told you much of what was really important in the world other than what was happening in the German Sudeten areas — the riots, and the nationality conferences in Prague. It remained to be seen whether or not what was happening in Czechoslovakia was the only thing that really mattered after all.

Illmann stubbed out his cigarette and began to read his findings.

‘The girl was naked, and there were signs that her feet had been bound. She had sustained two knife wounds to the throat. Nevertheless there existed strong indications that she had also been strangled, probably to silence her. It is likely that she was unconscious when the murderer cut her throat. The bruising bisected by the wounds suggests as much. And this is interesting. From the amount of blood still in her feet, and the crusted blood found inside her nose and on her hair, as well as the fact that the feet had been very tightly bound, it is my finding that the girl was hanging upside down when her throat was cut. Like a pig.’

‘Jesus,’ said Nebe.
