‘You know, I’m glad you came,’ he said. ‘As it happens I was going to speak to Schemm, my lawyer, this afternoon, and arrange for you to be paid. But since you are here I can write you a cheque.’ And so saying he went over to his desk with such alacrity that I thought he might have a gun in the drawer.

‘I’d prefer cash, if you don’t mind.’ He glanced up at my face, and then down at my hand holding the butt of the automatic in my jacket pocket.

‘Yes, of course you would.’ The drawer stayed shut. He sat down in his chair and rolled back a corner of the rug to reveal a small safe sunk in the floor.

‘Now that’s a handy little nut. You can’t be too careful these days,’ I said, relishing my own lack of tact. ‘You can’t even trust the banks, can you?’ I peered innocently across the desk. ‘Fireproof, is it?’ Six’s eyes narrowed.

‘You’ll forgive me, but I seem to have lost my sense of humour.’ He opened the safe, and withdrew several packets of banknotes. ‘I believe we said five per cent. Would 40,000 close our account?’

‘You could try it,’ I said, as he placed eight of the packets on the desk. Then he closed the safe, rolled back the carpet, and pushed the money towards me.

‘They’re all hundreds, I’m afraid.’

I picked up one of the bundles and tore the paper wrapping off. ‘Just as long as they’ve got Herr Liebig’s picture on them,’ I said.

Smiling thinly, Six stood up. ‘I don’t think we need ever meet again, Herr Gunther.’

‘Aren’t you forgetting something?’

He began to look impatient. ‘I don’t think so,’ he said testily.

‘Oh, but I’m sure you are.’ I put a cigarette in my mouth and struck a match. Bending my head towards the flame I took a couple of quick puffs and then dropped the match into the ashtray. ‘The necklace.’ Six remained silent. ‘But then, you already have it back, don’t you?’ I said. ‘Or at least you know where it is, and who has got it.’

His nose wrinkled with distaste, as if it detected a bad smell. ‘You’re not going to be tiresome about this are you, Herr Gunther? I do hope not.’

‘And what about those papers? The evidence of your involvement with organized crime that Von Greis gave to your son-in-law. Or do you imagine that Red Dieter and his associates are going to persuade the Teichmüllers to tell them where they are? Is that it?’

‘I’ve never heard of a Red Dieter, or — ’

‘Sure you have, Six. He’s a crook, just like you. During the steel strikes he was the gangster you paid to intimidate your workers.’
