9st 2 (only bright spot on horizon), reasons why people like going to musicals: mysterious unfathomable number, reasons Rebecca allowed to be alive 0, reasons for Mark, Rebecca, Mum, Una and Geoffrey Alconbury and Andrew Lloyd Webber or similar to ruin life: unclear.

Must keep calm. Must be positive. Was very bad luck all those things happening at once, no question about it. Completely understandable that Mark would just leave after all that and he did say he was going to call when he calmed down and ... Hah! I've just realized who that bloody card was from. It must have been the dry-cleaner. When I was trying to get it out of him about the fraud and saying "Don't think I don't know what's going on," I was dropping off my nightie. And I gave him Mark's address in case he was dodgy. The world is full of lunatics and madmen and I've got to go see Miss Saifuckinggon tonight.

Midnight. Initially, it wasn't too bad. It was a relief to get away from the prison of my own thoughts and the hell of dialling 1471 every time I went to the loo.

Wellington, far from being a tragic victim of cultural imperialism, looked coolly at home in one of Dad's 1950s suits as if he might have been one of the waiters from the Met Bar on his night off, responding with dignified graciousness while Mum and Una twittered around him like groupies. I turned up late so managed to exchange only the briefest of apologetic words with him at the interval.

"Is it strange being in England?" I said, then felt stupid because obviously it would be strange.

"It is interesting," he said, looking at me searchingly. "Do you find it strange?"

"So" burst in Una. "Where's Mark? I thought he was supposed to be coming too!"

"He's working," I muttered as Uncle Geoffrey lurched up, pissed, with Dad.

"That's what the last one said, didn't he!" roared Geoffrey. "Always the same with my little Bridget," he said, patting me dangerously near my bottom. "Off they go. Weeeeeeeh!"

"Geoffrey!" said Una, adding as if making light conversation, "Do you have older women who can't get married off in your tribe, Wellington?"

"I am not an older woman," I hissed.

"That is the responsibility of the elders of the tribe," said Wellington.

"Well, I've always said that was the best way, haven't I, Colin?" said Mum smugly. "I mean didn't I tell Bridget she should go out with Mark?"

"But when she is older, with or without husband, a woman has the respect of the tribe," said Wellington with a twinkle in my direction.

"Can I move there?" I said glumly.

"I am not sure you would be liking the smell of the walls." He laughed.

Managed to get Dad on one side and whisper, "How's it going?"

"Oh, not so bad, you know," he said. "Seems a nice enough feller. Can we take our drinks in with us?" Second half was a nightmare. Whole hideous jamboree on stage passed in a blur as mind went into a horrifying snowball-effect roll with images of Rebecca, Gary, vibrators and nighties getting more and more lurid as they spun past.

Fortunately the crush of people spewing out of the foyer and yelling with - presumably - joy prevented conversation till we all piled into Geoffrey and Una's Range Rover. We were going along with Una driving, Geoffrey in the front, Dad giggling merrily in the boot and me sandwiched between Mum and Wellington in the back when incident happened, horrifying and incredible.

Mum had just plonked a pair of enormous, goldrimmed glasses on her nose.

"I didn't know you'd started wearing glasses," I was saying, startled by this uncharacteristic nod in the direction of acknowledging the ageing process.

"I haven't started wearing glasses," she said gaily. "Mind that belisha beacon, Una."

"But" I said, "you are."

"No, no, no! I only wear them for driving."

"But you're not."

"Yes she is." Dad grinned ruefully as Mum yelled, "Mind that Fiesta, Una! He's indicating!"

"Isn't that Mark?" said Una suddenly. "I thought he was working."

"Where!" said Mum bossily.

"Over there," said Una. "Ooh, by the way, did I tell you Olive and Roger have gone to the Himalayas? Littered with toilet paper, apparently. The whole of Mount Everest."

I followed Una's pointing finger to where Mark, dressed in his dark blue overcoat and a very white, semi-undone shirt, was getting out of a taxi. As if in slow motion, I saw a figure emerging from the back of the cab: tall, slim, with long blonde hair, laughing up into his face. It was Rebecca.

The level of torture unleashed in the Range Rover was unbelievable: Mum and Una crazed with indignation on my behalf - "Well, I think it's absolutely disgusting! With another woman on a Friday night when he said he was working! I've a good mind to ring Elaine and give her what for; Geoffrey drunkenly saying "Off they go! Weeh!" and Dad trying to quieten the whole thing down. The only silent people were me and Wellington, who took my hand and held it, very still and strong, without saying a word.

When we reached my flat he climbed out of the Range Rover to let me out, with the babble of "Well! I mean his first wife left him, didn't she?"

"Well exactly. No smoke without fire," in the background.

"In darkness the stone becomes the buffalo," Wellington said. "In sunlight all is as it is."

"Thanks," I said gratefully, then stumbled back to the flat wondering if I could turn Rebecca into a buffalo and set her on fire without creating enough smoke to alert Scotland Yard.

10 p.m. My flat. Very black day. Jude, Shaz and I went emergency shopping and have all come back here to get ready for night on town, designed by the girls to keep my mind off things. By 8 p.m. things were already getting squiffy. "Mark Darcy's gay," Jude was declaring.

"Of course he's gay," snarled Shazzer, pouring out more Bloody Marys.

"Do you really think so?" I said, momentarily relieved by the depressing yet ego-comforting theory.

"Well, you did find a boy in his bed, didn't you?" said Shaz.

"Why else would he go off with someone freakishly tall like Rebecca, with no sense of girlfriend-hood, no tits and no bottom - i.e. a virtual man?" said Jude.

"Bridge," said Shaz, looking up at me drunkenly, "God, d'you know? When I look at you from this angle, you've got a real double chin."

"Thanks," I said wryly, pouring myself another glass of wine and pressing ANSWER PLAY again, at which Jude and Shazzer put their hands over their ears.

"Hi, Bridget. It's Mark. You don't seem to be returning my calls. I really think, whatever, I ... I'm really ... We - at least I feel - I owe it to you to be friends, so I hope you'll ... we'll. Oh God, anyway, give me a ring sometime soon. If you want to."

"Seems to have totally lost touch," grumbled Jude. "As if it's nothing to do with him when he's run off with Rebecca. You've really got to detach now. Look, are we going to this party or not?"

"Yurrr. Who's 'e bloody think he is'" said Sbaz. "Owe it to your Hggnah! You shoulssay, "Honey, I don't need anyone in my life becauseey owe it to me."'

At that moment the phone rang.

"Hi." It was Mark. Heart was inconveniently overtaken with great wave of love.

"Hi," I said eagerly, mouthing 'It's him', at the others. "Did you get your message? I mean my message?" said Mark.

Shazzer was jabbing my leg, frantically hissing, "Give it to him, go on.,

"Yes," I said, hoity-toitily. "But as I got it minutes after I saw you emerging from the taxi with Rebecca at 11 o'clock at night, I wasn't in the most amenable of humours."

Shaz stuck her fist in the air going "Yesss!!!" and Jude put her hand over Shazzer's mouth, gave me a thumbs up and reached for the Chardonnay.
