‘Haven’t you heard the nicknames they have for the BdM? The German Mattress League? Commodities for German Men?’ She put her arms about my neck and performed a variety of coquettish expressions she’d probably practised in front of her dressing-table mirror.

Her hot young breath tasted stale, but I let myself equal the competence in her kiss, just to be affable, my hands squeezing at her young breasts, kneading the nipples with my fingers. Then I cupped her chubby behind in both my moistening palms, and drew her closer to what was increasingly on my mind. Her naughty eyes went round as she pressed herself against me. I can’t honestly say I wasn’t tempted.

‘Do you know any good bedtime stories, Plato?’ she giggled.

‘No,’ I said, tightening my grip on her. ‘But I know plenty of bad ones. The kind where the beautiful but spoilt princess gets boiled alive and eaten up by the wicked troll.’

A vague glimmer of doubt began to grow in the bright blue iris of each corrupt eye, and her smile was no longer wholly confident as I hauled up her skirt and started to tug her pants down.

‘Oh, I could tell you lots of stories like that,’ I said darkly. ‘The sort of stories that policemen tell their daughters. Horrible gruesome stories that give girls the kind of nightmares which their fathers can be glad of.’

‘Stop it,’ she laughed nervously. ‘You’re frightening me.’ Certain now that things weren’t going quite to plan, she reached desperately for her pants as I yanked them down her legs, exposing the fledgling that nestled in her groin.

‘They’re glad because it means that their pretty little daughters will be much too scared to ever go into a strange man’s house, just in case he should turn into a wicked troll.’

‘Please, mister, don’t,’ she said.

I smacked her bare bottom and pushed her away.

‘So it’s lucky for you, princess, that I’m a detective and not a troll, otherwise you’d be ketchup.’

‘You’re a policeman?’ she gulped, tears welling up in her eyes.

‘That’s right, I’m a policeman. And if I ever find you playing the apprentice snapper again, I’ll see to it that your father takes a stick to you, understand?’

‘Yes,’ she whispered, and quickly pulled up her pants.

I picked up the pile of old shirts and towels from where I had dropped them on the floor, and pushed them into her arms.

‘Now get out of here before I do the job myself.’ She ran into the hall and out of the apartment in terror, as if I had been Niebelung himself.

After I’d closed the door on her, the smell and touch of that delicious little body, and the frustrated desire of it, remained with me for as long as it took to pour myself a drink and take a cold bath.
