‘He’s not stupid. It will take time. I’m not that good an interrogator, and I’m not about to take any short-cuts either. The last thing I want on this case is broken teeth on the charge sheet. That’s how Josef Kahn got himself folded away and put in the costume-hire hospital.’ I helped myself from the box of American cigarettes on Nebe’s desk and lit one with an enormous brass table lighter, a present from Goering. The prime minister was always giving away cigarette lighters to people who had done him some small service. He used them like a nanny uses boiled sweets.

‘Incidentally, has he been released yet?’

Nebe’s lean face adopted a pained expression. ‘No, not yet,’ he said.

‘I know it’s considered only a small detail, the fact that he hasn’t actually murdered anyone, but don’t you think it’s time he should be let out? We still have some standards left, don’t we?’

He stood up and came round the desk to stand in front of me.

‘You’re not going to like this, Bernie,’ he said. ‘No more than I do myself.’

‘Why should this be an exception? I figure that the only reason there aren’t any mirrors in the lavatories is so that nobody has to look himself in the eye. They’re not going to release him, right?’

Nebe leant against the side of the desk, folded his arms and stared at the toes of his boots for a minute.

‘Worse than that, I’m afraid. He’s dead.’

‘What happened?’

‘Officially?’

‘You can give it a shot.’

‘Josef Kahn took his own life while the balance of his mind was disturbed.’

‘I can see how that would read nicely. But you know different, right?’

‘I don’t know anything for certain.’ He shrugged. ‘So call it informed guesswork. I hear things, I read things and I make a few reasonable conclusions. Naturally as Reichskriminaldirektor I have access to all kinds of secret decrees in the Ministry of the Interior.’ He took a cigarette and lit it. ‘Usually these are camouflaged with all sorts of neutral-sounding bureaucratic names.

‘Well then, at the present moment there’s a move to establish a new committee for the research of severe constitutional disease — ’

‘You mean like what this country is suffering from?’

‘ — with the aim of encouraging “positive eugenics, in accordance with the Führer’s thoughts on the subject”.’ He waved his cigarette at the portrait on the wall behind him. ‘Whenever you read that phrase “the Führer’s thoughts on the subject”, one knows to pick up one’s well-read copy of his book. And there you will find that he talks about using the most modern medical means at our disposal to prevent the physically degenerate and mentally sick from contaminating the future health of the race.’

‘Well, what the hell does that mean?’
