‘Now let’s see, how old was she again? Fifteen? Sixteen? That’s about the same age as the girls who’ve been murdered. You know, maybe you just like them young. You feel ashamed of what you are, and transfer your guilt to them. How can they make you do these things?’

‘No, it’s not true, I swear it -’

‘How can they be so disgusting? How can they provoke you so shamelessly?’

‘Stop it, for Christ’s sake — ’

‘You’re innocent. Don’t make me laugh. Your innocence isn’t worth shit in the gutter, Gottfried. Innocence is for decent, law-abiding citizens, not the kind of sewer-rat like you who tries to strangle a girl in a massage parlour. Now sit down and shut up.’

He rocked on his heels for a moment, and then sat down heavily. ‘I didn’t kill anyone,’ he muttered. ‘Whichever way you want to cut it, I’m innocent, I tell you.’

‘That you may be,’ I said. ‘But I’m afraid I can’t plane a piece of wood without dropping a few shavings. So, innocent or not, I’ve got to keep you for a while. At least until I can check you out.’ I picked up my jacket and walked to the door.

‘One last question for the moment,’ I said. ‘I don’t suppose you own a car, do you?’

‘On my pay? You are joking, aren’t you?’

‘What about the furniture van. Are you the driver?’

‘Yes. I’m the driver.’

‘Ever use it in the evenings?’ He stayed silent. I shrugged and said: ‘Well, I suppose I can always ask your employer.’

‘It’s not allowed, but sometimes I do use it, yes. Do a bit of private contracting, that sort of thing.’ He looked squarely at me. ‘But I never used it to kill anyone in, if that’s what you were suggesting.’

‘It wasn’t, as it happens. But thanks for the idea.’

I sat in Arthur Nebe’s office and waited for him to finish his telephone call. His face was grave when finally he replaced the receiver. I was about to say something when he raised his finger to his lips, opened his desk drawer and took out a tea-cosy with which he covered the phone.

‘What’s that for?’

‘There’s a wire on the telephone. Heydrich’s, I suppose, but who can tell? The tea-cosy keeps our conversation private.’ He leant back in his chair underneath a picture of the Fiihrer and uttered a long and weary sigh. ‘That was one of my men calling from the Berchtesgaden,’ he said. ‘Hitler’s talks with the British prime minister don’t seem to be going particularly well. I don’t think our beloved Chancellor of Germany cares if there’s war with England or not. He’s conceding absolutely nothing.
