'You are upset.'

'No, I'm not.'

'Why are you upset?'

Why do I form the impression that Brooke is not really listening to me? This happens, sometimes. I talk to people, but a sort of emptiness seems to come over them, as though the face really is a mask, with the real person somewhere behind it, normally pressed up against the inside like a child with their nose against a sweet-shop window, but - when I am talking to them, trying to make some difficult or unacceptable point - lifting that internal self away from the mask and turning somewhere inside themselves, performing the mental equivalent of taking their shoes off and putting their feet up, having a cup of coffee and resting for a while, returning later only when they're good and ready, to nod inappropriately and make some wholly irrelevant remark redolent of stale thoughts. Perhaps it's me, I think. Perhaps only I have this effect on people; maybe nobody else does.

Well, this is paranoid thinking, I suppose, and I don't doubt the effect is one of those which, once one has the courage to broach the subject with other people, will prove to be extremely common, if not nearly universal ('Oh yes, I've felt that; that happens to me! I thought it was only me.')

Meanwhile, engineers Baker and Fowler have both succeeded in standing and pulling on their coats. Brooke is talking earnestly to engineer Fowler, who looks perplexed. Then enlightenment spreads across his face. He says something which Brooke nods at before coming back to me. 'Bouch,' he tells me, then picks up his own coat from the back of a couch.

'What?' I say.

'Tommy Bouch,' Brooke says, putting his coat on. 'He wanted the hat.'

'What for?'

'Don't know, Orr,' Brooke admits.

'Well, where is he?' I ask, looking round the bar.

'Went outside a while ago,' Brooke tells me. He buttons his coat. Fowler and Baker stand behind him, swaying uncertainly.

'Are you three going?' I ask, rather unnecessarily.

'Have to,' Brooke says, then takes my arm, leans closer. 'Urgent appointment at Mrs Hanover's,' he whispers loudly.

'Mrs -' I begin. Mrs Hanover's is a licensed brothel. I know that Brooke and his cronies visit it occasionally, and I suspect it is frequented mostly by engineers (a host of unsubtle allusions suggest themselves). I have been invited before, but made it clear I have no interest in attending. This reticence arises from vanity, not moral scruples, I have assured Brooke, but I suspect he still thinks I am - beneath my talk of sex, politics and religion - a prude.

'Don't suppose you want to come along, do you?' Brooke says.

'Thank you, no,' I say.

'Hmm, didn't think so,' Brooke nods. He takes my arm again, puts his mouth near to my ear. 'Thing is, Orr, it's a bit awkward . . .'

'What?' I watch engineer Fowler talking to a young man with long hair who is sitting in the shadows behind him. Another young man is slumped over the table behind him.

'It's Arrol's daughter,' Brooke says, glancing back over his shoulder.

'Who?'

'Chief Engineer Arrol's daughter,' Brooke whispers. 'She's sort of attached herself to us, you see, and that brother of hers has gone and fallen asleep, so if we leave now there won't be anybody to ... Look, you wouldn't mind sort of. . . talking to her, would you?'

'Brooke,' I say coldly, 'first of all you call me at five o'clock in the morning, then -' I get no further.

Baker, supported by an anxious-looking Fowler, stumbles into Brooke, and says, 'Think we'd better go now, Brooke; not feeling awfully . . .' Engineer Baker stops, seems to belch. His cheeks bulge; he swallows, then grimaces and nods in the direction of the steps to the lower floor.

'Got to go, Orr,' Brooke says hurriedly, grabbing one of Baker's arms while Fowler grasps the other. 'See you later. Thanks for looking after the girl. Have to make your own introductions, sorry.' The three of them barge past me; Brooke shoves the wide-brimmed hat back into my hands. Fowler drags Baker off towards the stairs, with Brooke in tow via Baker's other arm. 'I'll tell Tommy Bouch about the hat if I see him,' Brooke shouts.

They stagger together through the crowds, towards the stairs. As I turn, my attention is caught by the young man I saw Fowler talking to earlier; he is looking up, from rather baggy eyes, smiling at me.

Wrong. Not a young man; a young woman. She is wearing a dark, rather well-cut suit with wide trousers, a brocade waistcoat with a rather ostentatious gold chain across it, and a white cotton shirt. Her shirt collar is open, a black bow-tie hanging undone from it. Black shoes. Her hair is dark, shoulder length. She is sitting sideways on a seat, one leg drawn up under her. One dark hooked eyebrow hoists; I follow her gaze to where the tripod of engineers who have just left the table are attempting to navigate their way through the press of bodies at the head of the stairs. 'Think they'll make it?' She says. She tips her head to one side, one clenched fist supporting the back of her head.

'I think I'd want very good odds,' I reply. She nods thoughtfully and takes a drink from a long glass.

'Yes, me too,' she says. 'I'm sorry; I don't know your name.'

'My name is John Orr.'

'Abberlaine Arrol.'

'How do you do,' I say.

Abberlaine Arrol smiles, amused. 'I do as I like, Mr Orr. And yourself?'

One irrelevant reply deserves another; 'You must be Chief Engineer Arrol's daughter,' I say, putting the wide-brimmed hat on the end of the couch (where, with any luck at all, somebody else will pick it up).

'That's right,' she says. 'Are you an engineer, Mr Orr?' She waves one long, unringed hand at a seat beside her. I take off my coat, sit down.

'No, I'm a patient, under Dr Joyce.'

'Ahh,' she says, nodding slowly. She looks at me with a directness I've found unusual on the bridge, as though I am some complicated mechanism in which one small part has come adrift. Her face is young, but soft-looking in the way of an older woman's, though unlined; she is small-eyed, with the hoses obvious under the smooth skin at brow and cheek. Her mouth is quite broad, and smiling, but I find my gaze drawn to small crinkles of skin under her grey eyes, small folds, which give her a knowing, ironic look.

'What do they think might be wrong with you, Mr Orr?' Her eyes glance towards my wrist, but my medical name band is hidden by my cuff.

'Amnesia.'

'Ah really; from when?' She wastes no time between sentences.

'About eight months ago. I was . . . netted by some fishermen.'

'Oh, I think I read about it. They fished you out of the sea.'

'So I'm told. That's one of the many things I've forgotten.'

'Haven't they found out who you are yet?'

'No; no one has claimed me, at any rate. I don't match the description of any missing person.'

'Hmm, it must be strange.' A finger goes to her lips. 'I imagined it might be quite interesting and . . .' a shrug, 'romantic to have lost one's memory, but perhaps it's just frustrating?' She has rather fine, very dark eyebrows.

'Mostly frustrating, but also interesting, as is the treatment. My doctor believes in dream therapy.'

'And do you?'

'Not yet.'

'You will if it works.' She nods.

'Probably.'

'But,' she raises one finger. 'What if you have to believe in it before it can work?'

'I'm not sure that would accord with the good doctor's scientific principles.'

'But if it works, who cares?'

'Ah, but if one has belief without reason in the process, one may end up having belief without reason in the result.'

This makes her pause, but only for a moment.

'So you might think you're cured, when you're not,' she says. 'But there'd be a definite result; you'd either have your memory back or not.'

'Ah, but I might not; I might make it up.'
