Kelly stared now at Derek. 'You paid a fortune for it,' she said. 'And you've never dared to play it.'

'I wouldn't dare,' said Derek. 'What if I broke it, before I got to the deadlock point?'

'But what if it doesn't work? What if it doesn't run? What if it's a fake? Or a later version without the deadlock point?'

Derek nodded slowly. 'My thoughts entirely,' he said. 'Which is one of the reasons I've never played it. What if it is a fake? I have faith in it. The way Christians have faith in Christ. But what if there was suddenly some proof available, some unarguable proof that Christ didn't exist? That he never existed? And you could give this proof to a Christian, all packaged up in an original case like this one. What would you, as a Christian, do? Would you open the case? Or would you refuse to open it and go on believing in Christ?'

'I'd open the case,' said Kelly.

'But what if you didn't want the existence of Christ to be disproved? What if you wanted Christ to exist?'

'Hm,' said Kelly. 'If I wanted it more than anything else in the world, then I suppose that I wouldn't open the case, original or not.'

'Exactly,' said Derek. 'Which is why I'll never play this game. I own it. It's a collector's Holy Grail. I believe in it totally. As long as I never slot it into the console, then it remains the centrepiece of my collection and I can believe in it totally.'

'Let's play it,' said Kelly.

'No way!' said Derek. 'No way at all.'

'All right,' said Kelly. 'You go out of the room for half an hour and I'll play it.'

'No way at all!'

'Ah,' said Kelly. 'But I might not play it. I might just look at it.'

'You'd play it,' said Derek.

'But I wouldn't tell you. I won't tell you whether I did play it or whether I didn't. Whether it works or whether it doesn't. I promise I won't tell you anything.'

'No,' said Derek. 'What if you played it and you broke it?'

'You'd never know. You'll never play it and I'll never tell you, it will be exactly the same for you as before.'

'Oh no,' said Derek. 'Because you'll know and I'll know you know.'

‘I’ll give you money,' said Kelly.

'No,' said Derek.

Kelly chewed upon her Cupid's bow. 'I'll er…'

'Er?' said Derek.

'I'll give you a blow job,' said Kelly.

'You'll what?'

'I will,' said Kelly. 'If you let me play.'

Derek dithered, but it did have to be said, although only to himself and only to himself when alone in his room, that Derek had never actually had a blow job.

'Well…' said Derek.

'You'll have to wear a condom,' said Kelly. 'But I will give you a blow job.'

'Right here and now?'

'Afterwards,' said Kelly. 'After I've played the game.'

'And what if it doesn't work?'

Kelly looked at Derek. It would be so easy. And so so cruel.

'Whether it works or not,' she said.

Derek looked at Kelly. Here she was, one of the most beautiful women he had ever seen in his life. And she was here in his bedroom and she was prepared to give him a blow job, if he let her play one of his video games. This was heaven, wasn't it? This was joy, joy, happyjoy.

Happy Happy Joy.

But.

Damn it. But.

But this was his game. This was his Holy Grail of games and this game, owning this game, owning the very concept of owning this game, this was his. It was something of value. Something that mattered, something that he cared about. Not everyone could understand a principle like that. Most men would just say, 'Go for the blow job, are you mad?' But collecting games was Derek's life. And things that mattered, things that had value, that deserved to be respected, that deserved respect, you didn't mess with things like that, you didn't devalue them. Not if you really cared. You didn't sell them out.

Derek looked once more upon Kelly. That body, those breasts, that face, that mouth.

'No,' said Derek, shaking his head. 'I won't do it. No.'

Kelly looked at Derek, and then she slowly smiled. 'Derek,' she said. 'You have just passed up the blowjob of a lifetime.'

Derek sadly nodded his head. 'Yes, I know,' he said.

'But,' said Kelly. 'In doing so, you have made a friend for life.' And she put out her hand to Derek. And Derek shook that hand.

Derek didn't know quite why he shook it. Well, perhaps he did, but he smiled with some relief as he shook it, and shook it firmly, did he.

So to speak.

'Well,' said Derek, when all the shaking was done. 'That was very stressful. And I'm glad it's over. Would you, er, care for a game of pong?'

'Oh God yes!' said Kelly.

'Then be prepared to have your arse most well and truly kicked.'

'Boy, by the time I'm finished with you, you won't be able to sit on yours for a week.'

'You reckon?'

'I reckon.'

'Let's play.'

As Kelly didn't get back to her digs until after five in the morning, she lay rather longer in bed than normally she would have done.

She didn't raise her blondie head until half past ten, which didn't give her much time to get showered and dressed and breakfasted before she met up with Derek at eleven.

She had arranged to meet him in the saloon bar of a Brentford pub called the Shrunken Head.

Starting off the day in a pub might not have seemed to many people the right and proper thing to do. But then many people wouldn't have known, as Derek did, and as Derek told Kelly, that in the corner of the saloon bar of the Shrunken Head there was an original Space Invaders machine in fully working order.

And, as they'd come up even in the previous night's playing of pong, a decider would have to be played. So why not play it out upon this very machine?

'Why indeed not?' Kelly had said.

Kelly's breakfast plate was puce, as was the tablecloth it sat upon. Kelly's landlady, Mrs Gormenghast (daughter of the remarkable Zed and sister to Zardoz, the ornamental hermit, who lived all alone in a tree), stoked up the fire in the front sitter, where Kelly sat late-breakfasting. Mrs Gormenghast wore a pucely hued jumpsuit of a type which has happily gone the way of the split-knee loon pant and the Beatle wig. Not to mention the stylophone.

As if anybody would.

Kelly wore a simple summer frock of turquoise blue. It had no buttons to loosen, which given the fire's heat and all the closed windows, didn't help in the ever-warming atmosphere.

'Is that fire really necessary?' Kelly asked, as she mopped at her brow with a puce napkin.

'It keeps the Devil out,' said Mrs Gormenghast. 'Always keep a fire in your hearth and you'll never have to fear the Devil. My late husband used to say that. He knew what he was talking about.'

'Was he a preacher man?' Kelly asked.

'No, he was a coalman.'

'How do you get your fried eggs so puce?' Kelly asked.

'It's an old Indian trick, taught to me by an old Indian woman trickster. Puce is the colour of at-oneness. Did you know that if you take every single colour there is, about an ounce of each and mix them all together in a big pot, a very big pot obviously, the end result will be puce. Explain that if you will.'

'I can't,' said Kelly. 'But I suppose that…'

'You can split light with a prism, can't you?' asked Mrs Gormenghast.

'As far as I know,' said Kelly.

'Invisible light, it contains all the colours of the rainbow.'

Kelly nodded.

'So how come, if you mix all colours together in a pot they don't end up as an invisible transparent liquid?'

'Well…' said Kelly.

'Yes, that's easy for you to say. Well, well, I'll tell you why, well. Because prisms don't tell all of the truth. Nothing tells all of the truth. Nothing and nobody. The ultimate colour of the universe is puce. Mrs Charker down the road is of the mistaken belief that it is pink. Naturally, I respect her opinions, even if I know they are wrong.'
