‘Well, it seems like I did hear something. About a month ago, a fellow by the name of Kurt Mutschmann finishes two years’ cement at Tegel Prison. From what I’ve heard about him, Mutschmann is a real craftsman. He could open the legs of a nun with rigor mortis. But the polyps don’t know about him. You see, he got put inside because he clawed a car. Nothing to do with his regular line of work. Anyway, he’s a German Strength man, and when he came out the ring was there to look after him. After a while they set him up with his first job. I don’t know what it was. But here’s the interesting part, Herr Gunther. The boss of German Strength, Red Dieter, has now got a contract out on Mutschmann, who is nowhere to be found. The word is that Mutschmann double-crossed him.’

‘Mutschmann was a professional, you say.’

‘One of the best.’

‘Would you say murder was part of his portfolio?’

‘Well,’ said Neumann, ‘I don’t know the man myself. But from what I’ve heard, he’s an artist. It doesn’t sound like his number.’

‘What about this Red Dieter?’

‘He’s a right bastard. He’d kill a man like someone else would pick their nose.’

‘Where do I find him?’

‘You won’t tell him it was me who told you, will you, Herr Gunther? Not even if he were to put a gun to your head.’

‘No,’ I lied; loyalty goes only so far.

‘Well, you could try the Rheingold Restaurant on Potsdamer Platz. Or the Germania Roof. And if you take my advice you’ll carry a lighter.’

‘I’m touched by your concern for my well-being, Neumann.’

‘You’re forgetting the money,’ he said, correcting me. ‘You said I’d get another 200 if it checked out.’ He paused, and then added: ‘And a hundred now.’ I took out my wallet again and thumbed him a couple of fifties. He held the two notes up to the window to scrutinize the watermarks.

‘You must be joking.’

Neumann looked at me blankly. ‘What about?’ He pocketed the money quickly.

‘Forget it.’ I stood up and dropped some loose change onto the table. ‘One more thing. Can you remember when you heard about the contract on Mutschmann?’ Neumann looked as thoughtful as he could manage.

‘Well, now that I come to think of it, it was last week, about the time that I heard about this Junker getting killed.’

I walked west down Unter den Linden towards Pariser Platz and the Adlon.
