He smiled, but it was the smile of someone who thinks that they understand something when really they understand nothing. She said, 'Compulsive behaviour is to a large extent something that people rely upon to get out of bed in the morning. It's what makes the world go around.'

He shook his head. 'No, that's habit. If something is compulsive it's usually bad for you.'

She smiled at him icily. 'Like s.e.x?'

He smiled back. 'That's pleasure.'

The waiter arrived at the table with the starters, some spring rolls and prawn crackers. Sh.e.l.ly ate a couple of the crackers and then started on a spring roll. He looked down at his plate but didn't feel hungry. She said, 'The more I indulge my compulsions, the less I feel them ruling my life. It's weird. You'd think it would be the other way around but it isn't. Eat up, it's delicious.'

He tried a mouthful and it did taste good.

Her voracious appet.i.te, which had developed two or three years into their relationship, had always violently irritated him. When they had first started going out she ate virtually nothing. When they went to restaurants he would joke about how little she ate as she ordered the salad option and ate very slowly, chewing each mouthful with great restraint and discipline. He thought it appropriate that women should behave this way; women who gained too much enjoyment from food, greedy women, were usually too demanding in bed. They made him nervous.

He stared nervously at Sh.e.l.ly as she chewed and swallowed with great finesse and rapidity. After several minutes the waiter came to take their plates away. Sean had left most of his starter but Sh.e.l.ly's plate was clean.

The waiter smiled at her as he took her plate. 'You enjoyed that?' Sh.e.l.ly nodded. 'It was delicious, but don't worry, I've still got room for the main course.'

The waiter pulled a face which implied that he found it hard to believe that someone who looked as good as Sh.e.l.ly didn't have to starve themselves to keep in trim. Sean was sure that he was staring at her b.r.e.a.s.t.s. He nodded curtly and dismissed the waiter with a brisk thank you.

Sh.e.l.ly touched her napkin to both corners of her mouth. She looked around her and studied the other people in the restaurant. Sean stared at her face; her green eyes, her strong nose, her dark black eyebrows and her curling fringe. He said, 'Your hair suits you in that short bob style.'

She dragged her eyes from the couple sitting by the door and focused them dreamily on Sean's face. 'Does it?'

She paused and then before he could answer said, 'Yes, I think it does. It's still too curly. Bobs should be very straight ideally.'

He nodded in silence, pretending that he understood or cared. She reached out one of her hands and caught a droplet of wax that was dripping down the small white candle in the centre of the table on the side of her middle finger. It felt hot on her hand for a second and then solidified. She began to draw her hand back again but before she could properly do so Sean put out his hand and took hold of hers. Their arms were suspended uncomfortably in mid-air. She squeezed his hand fondly and then drew hers away.

The waiter brought the main course. As he dished up his portions Sean said, 'What's going to happen now, between us?'

In his car on his way around to her flat he had imagined this situation but the roles had been reversed. He had visualized Sh.e.l.ly, all tearful and cloying, biting her lip, begging him to come back to her. She'd change, she'd be less possessive, anything.

Sh.e.l.ly didn't answer his question immediately. He repeated himself: 'What's going to happen now, Sh.e.l.ly?'

She frowned and eventually said, 'I don't know.'

She started eating. She had chicken chow mein with mixed vegetables in soy sauce. It tasted heavenly. Sean couldn't eat. Everything seemed to be going wrong. He knew that Sh.e.l.ly needed him, needed someone. He put down his knife and fork and said, 'Sh.e.l.ly, please tell me if there's someone else.'

She didn't reply. He began to feel jealous and angry, bitter. After a few minutes watching her eat he said, 'I bet you'll regret this meal tomorrow. It'll take it's toll on your figure.'

Sh.e.l.ly stopped chewing and looked into his eyes. 'I shouldn't think so.'

He frowned. 'How come?'

She finished her mouthful and curled some more chow mein on to her fork, 'I don't gain weight any more. It's connected to something called symbiosis.'

He grimaced. 'What's that supposed to mean?'

'It means that I don't gain weight any more but I can eat what I like.'

The flame on the candle flickered for a moment as the door of the restaurant opened. His eyes focused on the flame for a second, then returned to her face. 'How is that possible?'

She sighed and put down her knife and fork and then leaned forward on her elbows and whispered, 'I've got a tapeworm.'

He wasn't sure that he'd heard her correctly. 'What?'

She smiled as though what she was telling him caused her infinite joy. 'I've got a tapeworm, Sean, it's symbiosis. We both depend on each other to carry on.'

Sean shook his head in disbelief. 'What do you mean, Sh.e.l.ly? Is this a joke or something?'

Worms disgusted him. He had seen part of a nature programme on television a few weeks before which had featured something about worms that had made him almost physically sick. He had turned it over straight away.

Sh.e.l.ly returned to her meal, unperturbed. After a mouthful she said, 'I got him by eating raw mincemeat. It took a while and obviously I had to specify certain parts of the animal, you know, stomach, offal. I actually told the butcher that I wanted meat minced for my dog. As I said though, it took several attempts.'

Sean's lip curled in disgust. 'You ate raw dog meat?'

She shook her head. 'No, low quality meat, not from a can. Lots of animals get tapeworms. Obviously though there are many different varieties. It's very complicated because I think they reproduce in lots of different ways. I went to great lengths to get mine.'

Sean still couldn't be sure that Sh.e.l.ly wasn't joking. He said, 'What do you call it? Trevor?'

She laughed. It was the first time that she had laughed properly all evening. 'I don't have a formal name for him-I think he's as.e.xual. I haven't read all that much about them.'

The waiter returned to the table to make sure that their meal was all right. Sh.e.l.ly answered, smiling, 'It's absolutely delicious, thank you.' Sean just continued to stare at her face. Once the waiter had moved away he picked up his fork and tried to eat one of the lightly battered prawn b.a.l.l.s on his plate. As he chewed Sh.e.l.ly said, 'You see, the tapeworm consumes my undigested food so that it doesn't have the chance to turn into fat. That's my theory anyway. He then uses the food to grow and reproduce himself. He sort of develops another segment which divides away from his body after a certain period. This segment, I'm slightly confused on this point though, this segment then either stays in the stomach, hooking on to a prime place, or it's flushed out with your body fluids.'

Sean said nothing. He was pushing prawn and batter around his mouth but he couldn't swallow. Sh.e.l.ly took this silence as an indication of interest so she added, 'I'm glad you're not a biologist, Sean, because I'm explaining this very badly'

Sean carried on chewing. On his forehead were slight beads of perspiration. He picked up his napkin and blotted them. Sh.e.l.ly took a sip of wine and said, 'I have to be careful about alcohol. I sometimes think that it must be bad for him so I don't drink very much any more. That's something else good that he's brought to my life.'

Sean pushed his mouthful of well-chewed food into his cheek and said, 'What happens when it grows, Sh.e.l.ly?'

She shrugged and picked up her knife and fork again, 'I'm not absolutely sure. In general I think they just get bigger and bigger until they fill up all your tubes. I think they can grow to an enormous size. They just grow bigger and bigger and reproduce.'

Sean shuddered. 'And what happens then? I'm sure they're harmful.'

Suddenly an image flashed into his mind, an image that he had seen accompanied by the voice of David Attenborough. There had been a snail on a leaf. As it ate the leaf it had consumed some sort of worm the size of a pin head. The worm lived and grew inside the snail, created a home for itself in this new snail-stomach world. After several weeks the maggot had grown rather large. It became visible inside one of the snail's two feelers. It grew and grew until eventually it filled the feeler entirely. After a while it looked as though, instead of a feeler sticking out of the snail's head, it had a large, independent, squirming maggot whose movements were curtailed only by a thin layer of the snail's translucent skin. The maggot moved, squelched, writhed under the snail's skin, eating, growing.

Several days later the snail's other feeler began to fatten up, to grow pale, to move against its own will as another maggot appeared in this feeler. Sean hadn't been able to tell whether this was the same maggot or a different one. They certainly looked like two fully formed and independent creatures. Eventually the snail had no feelers left, just two white maggots sticking out of the top of its head, living on its juices, eating it while it carried on moving and living and breathing. The maggots shuddered and vibrated inside the snail's feelers, its eyes, prisoners in its skin, eating him.

Sean had yelped his horror and had s.n.a.t.c.hed for the remote control to switch it off. He couldn't stop thinking about it afterwards though. He was sure that the snail must've died, but after how long? He felt like gagging.

Sh.e.l.ly had almost completed her meal. She was saying, 'Sean, eat something. It's such a waste.'

He spat out his masticated mouthful into a napkin. She said, 'I haven't been so happy in a long time, Sean. The only tiny way that I notice the worm is when I go to the toilet. Often when I go now a segment of the worm comes out in my urine.'

One of Sean's main rules of love was that women didn't go to the toilet; or if they went they did different things there than men. He refused to have his idealism shattered. Sh.e.l.ly had always been very circ.u.mspect about her personal habits in the past. She had always called the toilet the Little Girls' Room. When she said it he liked to imagine that women kept dolls and horses and perfume and lipstick in the Little Girls' Room, that they popped in there for a bit of fun and then came out again, beautiful, perfect and squeaky clean. He was a firm believer in the use of feminine deodorants.

Sh.e.l.ly was saying, 'I think the segment is just part of the worm that is dead because when I've studied it it doesn't move or anything. It's not like an independent life form ...'

Sean couldn't believe that Sh.e.l.ly was saying these things; he interrupted, 'This is all a tiny bit intimate, Sh.e.l.ly'

She shrugged, 'I don't know. I think I've really changed in that respect over the past few months. I used to be embarra.s.sed about my body before and the things that it does naturally. My tapeworm has changed all that. It's like I'm now involved in a very natural and obvious relationship. It's like I can see at last how I relate to the world as a creature; to trees and gra.s.s and cows and pigs, and the moon's cycles and the sea. We all are alive in a similar way. It's all connected and we all depend on each other, in a sort of chain of existence.'

As she spoke the waiter returned to their table and took away their plates. Sh.e.l.ly smiled at him as he completed this task and said, 'I'd love an Irish coffee.'

He nodded and looked at Sean. Sean said, 'Just a plain coffee for me, please.'

Sh.e.l.ly straightened the table cloth and picked up a few crumbs to put in the ashtray. Sean felt inside his jacket pocket and took out a couple of cigarettes. He offered Sh.e.l.ly one. She shook her head. 'I've given up.' He raised his eyebrows then stuck a cigarette in his mouth and lit it. After inhaling he said, 'Sh.e.l.ly, you've got to get rid of that worm.'

She smiled. 'No.'

He exhaled vigorously. 'Well, what's going to happen when it grows to an enormous size? I'm sure you eat enough to treble its size every other day.'

She ignored this insult and said, 'I'm going to keep this one for ten months then get rid of it. Afterwards I'll get another small one and start from scratch all over again. That means it'll never get out of control.'

The waiter brought them their coffees. Sh.e.l.ly thanked him and took a sip of the hot, sweet, creamy liquid. Sean was momentarily quiet so she said, 'I'm going to have to read up on the whole thing because I'm not one hundred per cent sure how they reproduce. If the little segments that come out in my urine are baby worms then maybe I'll have to try and swallow one of those.' She paused and then added, 'They aren't very big but they've got hooks on them. When I pee they hang on to the lip of my body with their hooks and I have to unhook them myself. It's quite simple when you know how.'

Sean's expression was full of an incredulous horror. She smiled. 'It's all right, Sean, it doesn't hurt and it doesn't bother me.'

Sean's mind was now turning over very rapidly. He was thinking of the s.e.x they had indulged in an hour or so before. He couldn't stop himself; he said, 'I couldn't have caught one earlier, could I?'

She frowned. 'I shouldn't think so.'

Then she smiled. 'I think you would've seen it if it had hooked on to the end of your p.r.i.c.k.' She started to laugh. 'Imagine if the entire worm had hooked itself on, all eleven or twelve inches of it. You'd have become rather confused when you went to the bathroom!'

She spluttered with laughter as she sipped her coffee.

Sean was stony-faced. He said, 'You don't give a s.h.i.t about me any more, do you? About my feelings in all of this?'

She stopped laughing and shrugged. 'You've never given a s.h.i.t about me in the past, Sean. In fact I think that I can honesuy say that I have had more help and support from my tapeworm over the past five months than you have given me in the last four years.' As she said this she tapped her stomach with her left hand and then took a swig of her Irish coffee.

Sean didn't know whether he wanted to live with her any more, whether he loved her, but he was d.a.m.n sure that he wasn't going to be compared to her tapeworm and come out of this comparison at a disadvantage. He said, 'That thing is eating you up inside. It's a parasite.'

She nodded. 'Yes it is, and the two of you have a whole lot in common. Unfortunately, you didn't improve my self-image like this tapeworm has. It needs me. You never needed me. It's helped me. You never helped me.'

She finished her coffee and he stubbed out his cigarette. She started to put her jacket on. 'I've got a new direction in my life now, Sean. I've learned that I can survive without you, that I can be attractive and desirable and funny and interesting without needing to have you around to tell me what I am or what I can be.'

He shook his head. 'You've got a real problem, Sh.e.l.ly.'

She stood up. 'No, you have, Sean. I'm leaving now and you can pay the bill.'

As she left the restaurant she winked at the waiter.

The Piazza Barberini.

TINA WAS DOING ROME on a budget. Her companion was horrible. He was called Ralph. She met him accidentally, and he stuck to her like a burr, like a leech, until he grew bored of her. Then he let go, just as suddenly.

He had, she discovered, over seven different ways of describing the r.e.c.t.u.m. His favourite was ring which he used and used until it was quite worn out. Ironically-she just knew this was funny-Ralph was actually an a.r.s.ehole himself. But she was too polite to say anything. He even looked like an a.r.s.ehole. Not literally, but he wore dark gla.s.ses, a furry trilby-right there, on the back of his head, monstrously precarious-and thick-soled loafers. She presumed that he thought his look was, in some way, Italian. She knew better. Even the Italians knew better.

Ralph was staying at a pensione south of Termini. It wasn't particularly salubrious around there. Tina didn't like it. She, by contrast, was staying in Old Rome, in the heart of Rome, close to the fruit market, the best piazza, the better cafes.

Tina had met Ralph while she was queueing for the Vatican Museum. It had been a ridiculously long queue, but she presumed that the wait would be worth it. Ralph had joined the queue behind her, had introduced himself, had asked whether she'd mind saving his place for him while he popped off for a minute, then disappeared. An hour later, when she'd nearly reached the front, he reappeared again. She'd completely forgotten about him by then. She almost didn't recognize him. His gla.s.ses were pushed up on to his head. His eyes-bold, empty-stared at her: a mucky brown. Two round hazelnuts. He said he didn't have quite enough money for the entrance fee-'What? You're kidding! That much?'-so she paid for him on the understanding that he'd pay her back later.

He never did. Ralph was from Reading. He worked for British Telecom. He had a smattering of Italian. He could order coffee, ice-cream, several flavours of pizza, without even consulting his guidebook.

Tina felt sorry for him. He wore a Lacoste polo shirt, but it wasn't actually Lacoste because the alligator was facing the wrong way. She knew about these things. She was training to be a buyer at Fenwicks, New Bond Street, London. Ah, yes.

Ralph tried to persuade Tina to have a piece of brightly coloured cotton twine plaited into her hair on the Spanish Steps. Several men, unkempt, like hippies, were offering this service for a small sum.

'I'd rather not,' she said, noticing their dirty hands, their tie-dyed shirts. 'I think I might just climb up to the top of the steps and look at the view.'

Ralph followed her. He was like a naughty spaniel; bored, precocious, snapping at her heels.

The view was fine. When they'd had enough of it, Ralph said, 'I wanna take you somewhere special. It's called the Piazza Barberini. It's not far from here, just down the hill. When she was in Rome, Sophia Loren used to live nearby.'

He took hold of her arm. Tina allowed herself to be led. She followed him obligingly because it was a pretty street, a steep, deep incision into the hillside. Grand houses frowned out on either side of them.

She was too obliging. What kind of girl, after all, takes any trip on her own? A bold girl? A silly girl? Oh, she wanted to be both, for once. Even Ralph, even he was a step in the right direction. A step, and she was on a trip, a voyage. Rome, she knew, held something special just for her: a fresco, a figurine, a shady walkway, an orange tree. If she kept on looking, she would find it.

In the Piazza Barberini she paused for a moment to stare at a fountain.

I've got fountains,' Ralph said, contemptuously, 'spouting out of my brush.'

Close by was a second, smaller fountain which was covered in big carved bees. 'That,' Tina said, pausing for a moment, 'is very sweet.'

'Yeah.' Ralph walked on.

'And if it was in London,' she said, 'it would be covered in bird dirt. They don't seem to have pigeons here, or if they do, they don't mess nearly as much.'

'In Rome,' Ralph said, conversationally, 'you're only considered gay if you're pa.s.sive during s.e.x. If you screw other men, but aren't screwed, then you're not gay.'

Tina scowled. 'That's disgusting.'

Ralph grinned. 'In Italy the men are men and the women are glad of it.'

Tina rolled her eyes. She decided that Ralph had been in Rome for too long. He'd been here a week already. She'd arrived a mere thirty-six hours ago. She was glad that she was staying for only five days. After seven days Ralph was bored. He seemed incapable of seeing the prettiness around him. He was growing cynical. He didn't appreciate how good the weather was.

Ralph led Tina towards a church-In Rome, she thought, what else?-and up some steps. At the top, slightly out of breath, he turned and proclaimed, quite seriously: 'Here lies dust, ashes, nothing.'

'What?'

'It's written on the wall,' he said. 'Inside. I kind of liked it.'

She moved towards the entrance. 'No,' he said, turning from her, 'not there. This way.'
