‘Rienacker, Wolf Rienacker. Gestapo. You used to be a bull, didn’t you? Up at the Alex.’

‘That’s right.’

‘And now you’re a sniffer. So what brought you up here?’

‘Looking for Herr Von Greis.’ I glanced about the room. There was a lot of mess, but it didn’t seem that there was much missing. A silver epergne stood immaculate on a sideboard, the empty drawers of which were lying on the floor; and there were several dozen oil paintings leaning in neat ranks against the walls. Clearly whoever had ransacked the place hadn’t been after the usual variety of loot, but something in particular.

‘I see.’ He nodded slowly. ‘You know who owns this apartment?’

I shrugged. ‘I had supposed it was Herr Von Greis.’

Rienacker shook his bucket-sized head. ‘Only some of the time. No, the apartment is owned by Hermann Goering. Few people know about it, very few.’ He lit a cigarette and threw me the packet. I lit one and smoked it gratefully. I noticed that my hand was shaking.

‘So the first mystery,’ continued Rienacker, ‘is how you did. The second is why you wanted to speak to Von Greis at all. Could be that you were after the same thing that the first mob were after? The third mystery is where Von Greis is now. Maybe he’s hiding, maybe someone’s got him, maybe he’s dead. I don’t know. This place was done over a week ago. I came back here this afternoon to have another poke around in case there was something I missed the first time, and to do some thinking, and what do you know, you come through the door.’ He took a long drag on his cigarette. In his enormous ham of a fist it looked like a baby’s tooth. ‘It’s my first real break on this case. So how’s about you start talking?’

I sat up and straightened my tie and tried to fix my sodden collar. ‘Let me just figure this out,’ I said. ‘I’ve got this friend up at the Alex who told me that the police don’t know about this place, and yet here you are staking it out. Which leads me to suppose that you, or whoever it is you’re working for, likes it that way. You’d prefer to find Von Greis, or at least get your hands on what makes him so popular, before they do. Now, it wasn’t the silver, and it wasn’t the paintings, because they’re still here.’

‘Go on.’

‘This is Goering’s apartment, so I guess that makes you Goering’s bloodhound. There’s no reason Goering should have any regard for Himmler. After all, Himmler won control of the police and the Gestapo from him. So it would make sense for Goering to want to avoid involving Himmler’s men more than was necessary.’
