‘There’s a little Jewish snapper at this rub-joint we’re going to,’ he said enthusiastically. ‘A real scorcher. She’s got a plum that’s like the inside of a conger-eel, just one long piece of suction muscle. The kind to suck you in like a minnow and blow you right out of her arse. Best bit of damned plum I’ve ever had.’ He shook his head doubtfully. ‘I don’t reckon there’s anything to beat a nice ripe Jewess. Not even a nigger-woman, or a Chink.’

‘I never knew you were so broad-minded, Becker,’ I said, ‘or so damned cosmopolitan. Christ, I bet you’ve even read Goethe.’

Becker laughed at that one. He seemed to have quite forgotten Poliza. ‘One thing about Evona,’ he said. ‘She won’t talk unless we relax a little, if you know what I mean. Have a drink, take things easy. Act like we’re not in a hurry. The minute we start to act like a couple of official stiffs in our trousers she’ll haul down the shutters and start polishing the mirrors in the bedrooms.’

‘Well, there’s a lot of people like that these days. Like I always say, people won’t put their fingers near the stove if they figure you’re stewing a broth.’

Evona Wylezynska was a Pole with an Eton crop smelling lightly of Macassar oil, and a dangerous crevasse of cleavage. Although it was only the mid-afternoon she wore a peignoir of peach-coloured voile over a matching heavy satin slip, and high-heeled slippers. She greeted Becker like he was there with a rent rebate.

‘Darling Emil,’ she cooed. ‘Such a long time since we seen you here. Where have you been hiding?’

‘I’m off Vice now,’ he explained, kissing her on the cheek.

‘What a shame. And you were so good at it.’ She gave me a litmus-paper sort of look, as if I was something that might stain the expensive carpet. ‘And who is this you’ve brought us?’

‘It’s all right, Evona. He’s a friend.’

‘Does your friend have a name? And does he not know to take his hat off when he comes into a lady’s house?’

I let that one go, and took it off. ‘Bernhard Gunther, Frau Wylezynska,’ I said, and shook her hand.

‘Pleased to meet you, darling, I’m sure.’ Her thickly accented, languorous voice seemed to start somewhere near the bottom of her corset, the faint outline of which I could just about make out underneath her slip. By the time it got to her pouting mouth it had more tease than a fairy’s kitten. The mouth was giving me quite a few problems too. It was the kind of mouth that can eat a five-course dinner at Kempinski’s without spoiling its lipstick, only on this occasion I seemed to be the preoccupation of its taste-buds.
