'Oh look, there's Mark,' interrupted Piggy.

'Oh God, yah,' said Arabella, beadily. 'He's left his wife, hasn't he?'

'What I meant was, there isn't anything any good like Blind Date on the other side during the literary masterpieces, so I don't think that many people would be channel hopping.'

'Oh, Blind Date is 'good,' is it?' sneered Perpetua.

'Yes, it's very good.'

'And you do realize Middlemarch was originally a book, Bridget, don't you, not a soap?'

I hate Perpetua when she gets like this. Stupid old fartarse bag.

'Oh, I thought it was a soap or a shampoo,' I said, sulkily grabbing a handful of passing sate sticks and shoving them into my mouth. As I looked up I saw a dark-haired man in a suit straight in front of me.

'Hello, Bridget,' he said. I nearly opened my mouth and let all the sate sticks fall right out. It was Mark Darcy. But without the Arnold Palmer-style diamond-patterned sweater.

'Hello,' I said through my mouthful, trying not to panic. Then, remembering the article, turned towards Perpetua.

'Mark. Perpetua is . . . I began and then paused, frozen. What to say? Perpetua is very fat and spends her whole time bossing me around? Mark is very rich and has a cruel-raced ex-wife.

'Yes?' said Mark.

' . . . is my boss and is buying a flat in Fulham, and Mark is,' I said, turning desperately to Perpetua, 'a top human-rights lawyer.'

'Oh, hello, Mark. I know of you, of course,' gushed Perpetua as if she were Prunella Scales in Fawlty Towers and he were the Duke of Edinburgh.

'Mark, hi!' said Arabella, opening her eyes very wide and blinking in a way she presumably thought was very attractive. 'Haven't seen you for yonks. How was the Big Apple?'

'We were just talking about hierarchies of culture,' boomed Perpetua. 'Bridget is one of these people who thinks the moment when the screen goes back on Blind Date is on a par with Othello's 'hurl my soul from heaven' soliloquy,' she said, hooting with laughter.

'Ah. Then Bridget is clearly a top post-modernist,' said Mark Darcy. 'This is Natasha,' he said, gesturing towards a tall, thin, glamorous girl beside him. 'Natasha is a top family-law barrister.'

I had the feeling he was taking the piss out of me. Bloody cheek.

'I must say,' said Natasha, with a knowing smile, 'I always feel with the Classics people should be made to prove they've read the book before they're allowed to watch the television version.'

'Oh, I quite agree,' said Perpetua, emitting further gales of laughter. 'What a marvelous idea!'

I could see her mentally fitting Mark Darcy and Natasha in with an array of Poohs and Piggies round the dinner table.

'They should have refused to let anyone listen to the World Cup tune,' hooted Arabella, 'until they could prove they'd listened to Turandot all the way through!'

'Though in many respects, of course,' said Mark's Natasha, suddenly earnest, as if concerned the conversation was going quite the wrong way, 'the democratization of our culture is a good thing – '

'Except in the case of Mr. Blobby, who should have been punctured at birth,' shrieked Perpetua. As I glanced involuntarily at Perpetua's bottom thinking, 'That's a bit rich coming from her,' I caught Mark Darcy doing the same thing.

'What I resent, though' – Natasha was looking all sort of twitchy and distorted as if she were in an Oxbridge debating society – 'is this, this sort of, arrogant individualism which imagines each new generation can somehow create the world afresh.'

'But that's exactly what they do, do,' said Mark Darcy gently.

'Oh well, I mean if you're going to look at it at that level said Natasha defensively.

'What level?' said Mark Darcy. 'It's not a level, it's a perfectly good point.'

'No. No. I'm sorry, you're deliberately being obtuse,' she said, turning bright red. 'I'm not talking about a ventilating deconstructionalistic freshness of vision. I'm talking about the ultimate vandalization of the cultural framework.'

Mark Darcy looked as if he was going to burst out laughing.

'What I mean is, if you're taking that sort of cutesy, morally relativistic, 'Blind Date is brilliant' sort of line . . . ' she said with a resentful look in my direction.

'I wasn't, I just really like Blind Date,' I said. 'Though I do think it would be better if they made the pickees make up their own replies to the questions instead of reading out those stupid pat answers full of puns and sexual innuendos.'

'Absolutely,' interjected Mark.

'1 can't stand Gladiators, though. It makes me feel fat,' I said. 'Anyway, nice to meet you. Bye!'

I was just standing waiting for my coat, reflecting on how much difference the presence or absence of a diamond-patterned sweater can make to someone's attractiveness, when I felt hands lightly on my waist

I turned around. 'Daniel!'

'Jones! What are you doing skulking off so early?' He leaned over and kissed me. 'Mmmmmm, you smell nice,' then offered me a cigarette.

'No thank you, I have found inner poise and given up smoking,' I said, in a preprogrammed, Stepford Wife sort of way, wishing Daniel wasn't quite so attractive when you found yourself alone with him.

'I see,' he smirked, 'inner poise, eh?'

'Yes,' I said primly. 'Have you been at the party? I didn't see you.'

'I know you didn't. I saw you, though. Talking to Mark Darcy.'

'How do you know Mark Darcy?' I said, astonished.

'Cambridge. Can't stand the stupid nerd. Bloody old woman. How do you know him?'

'He's Malcolm and Elaine Darcy's son,' I began, almost going on to say, 'You know Malcolm and Elaine, darling. They came over when we lived in Buckingham – '

'Who in the – '

'They're friends of my parents. I used to play with him in the paddling pool.'

'Yes, I bet you did, you dirty little bitch,' he growled. 'Do you want to come and have supper?'

Inner poise, I told myself, inner poise.

'Come on, Bridge,' he said, leaning towards me seductively. 'I need to have a serious discussion about your blouse. It's extremely thin. Almost, when you examine it, thin to the point of transparency. Has it ever occurred to you that your blouse might be suffering from . . . bulimia?'

'I've got to meet someone,' I whispered desperately.

'Come on, Bridge.'

'No,' I said with a firmness that rather surprised me.

'Shame,' he said softly. 'See you Monday,' and gave me a look so dirty I felt like throwing myself after him shouting, 'Shag me! Shag me!'

11 p.m. Just called Jude and told her about Daniel incident, also about Malcolm and Elaine Darcy's son, whom Mum and Una had tried to get me off with at the Turkey Curry Buffet, turning up at the party looking rather attractive.

'Wait a minute,' said Jude. 'You don't mean Mark Darcy, do you? The lawyer?'

'Yes. What – do you know him as well?'

'Well, yes. I mean, we've done some work with him. He's incredibly nice and attractive. I thought you said the chap at the Turkey Curry Buffet was a real geek.'

Humph. Bloody Jude.

8st 7, cigarettes, 0, alcohol units 0, calories 1800.

Today is a historic and joyous day. After eighteen years of trying to get down to 8st 7 I have finally achieved it. It is no trick of the scales, but confirmed by jeans. I am thin.

There is no reliable explanation. I have been to the gym twice in the last week, but that, though rare, is not freakish. I have eaten normally. It is a miracle. Rang Tom, who said maybe I have a tapeworm. The way to get rid of it, he said, is to hold a bowl of warm milk and a pencil in front of my mouth. (Tapeworms love warm milk, apparently. They love it.) Open my mouth. Then, when the worm's head appears, wrap it carefully round the pencil.
