Harriet nodded. ‘But please don’t mention it to Monsieur Dubrov. She had to go away on business — for Vincent and the restaurant.’

‘Ah, yes… the famous Vincent. Have you met him?’

‘No, but I have seen his photograph. A lot of photographs!’

‘And?’ said Rom. ‘Is he a match for your ravishing friend?’

‘Well, it’s strange. I mean, it’s absolutely clear that she adores him. And of course he does have a very large moustache, which is important to her — all his family are famous for their moustaches — and photographs don’t tell you very much about people, do they? I think it must be his personality.’

‘A strong man, then?’

‘Very practical and Marie-Claude likes that. She gets very annoyed with people like Romeo. He should have got a chicken feather, she thinks, and laid it on Juliet’s lips to see if she was breathing, not rushed about and killed himself.’

‘Vincent is a chicken-feather man, then?’

‘Very much so, I understand.’ Harriet hesitated. ‘I can see Marie-Claude’s point. When I read about love in Cambridge — and I used to read a lot because my Aunt Louisa let me do my homework in the public library to save the gas — I got very discouraged. It seemed to me that as soon as you loved anyone very much, you were inevitably doomed. You know… Heloise and Abelard, Tristan and Isolde… To love in moderation was all right, but when it became excessive… total… you were punished. And yet it must be right, surely, to give everything? To hold nothing back? That must be what one wants to do?’

‘Yes, one wants to do just that. And I assure you that there are plenty of people who have loved truly and found their Avalon or their Hesperides and set up house there and tended their crops and lit their fires. Only who cares for them? Who writes about the valley with no earthquake, the river that is not in flood?’

He smiled at her, the grey eyes serene and comforting, and led her on to talk not of her home which he knew would give her pain, but of Cambridge itself, that incomparable city. And if he had doubted his feelings, those doubts would have been banished by the greed with which he longed to share her childhood and her memories.

Carmen brought coffee and a bowl of fruit which Rom studied attentively before picking a golden-pink pomegranate, which he placed not on Harriet’s plate, but into her obediently cupped hands. ‘Are you willing to take the risk?’ he asked. ‘They’re dangerous things, pomegranates.’

She caught the allusion instantly, as he had known she would.

‘Oh yes,’ she said. ‘It would be no punishment to have to remain here in this place. Or to return. Not for five months or fifty.’

She was silent, thinking of Persephone who had eaten her pomegranate in Hades, carried there by cruel Pluto, King of the Underworld. Had she minded going back into darkness, compelled to return for as many months as she had eaten seeds, while the world in her absence turned to winter? Or had Pluto looked a little like the man who faced her? Dark-visaged; sardonic; a few silver threads in the ink-black hair. In which case she must have wished she had eaten more seeds… And smiling, Harriet picked up the silver fruit knife.

But Rom now had decided that it was time for her to speak, for he had not forgotten that this was a meal with a purpose and, sensing that she might find it difficult to begin, he prompted her.

‘Tell me now, Harriet. Tell me why you stayed behind after the party. What was it you wanted to speak to me about?’

She put down the knife again, her face suddenly sombre. Increasingly it seemed impertinent to mention his past life. He must have contacts in every country in the world and certainly in England. If he had wanted to keep in touch with the place that had been his home, nothing could have been easier. And to give herself strength she summoned up again the image of the red-haired child in the maze, bewildered by the disaster that had struck his house.

‘It was Stavely,’ said Harriet in a low voice. ‘It was Stavely that I wanted to talk about.’

‘Stavely!’

The effect was extraordinary. The comradeship, the warmth that had been between them vanished in an instant. The dark, exotic face became blank, shuttered. But it was too late now to withdraw.

‘Forgive me — but you did live there, didn’t you, as a child?’

‘Yes. I lived there for the first nineteen years of my life.’

She nodded. ‘I knew. Even before you named the manatee. When you stepped out of the trees, I knew.’

He could make no sense of this and sat tracing the pattern of the tablecloth with one finger. From Stavely, where Henry and Isobel presumably dwelt in connubial bliss, there could come nothing that one way or another could fail to cause him pain.

‘I don’t know if you’ve heard,’ said Harriet, forcing herself to go on, ‘but things are very bad there.’

‘No, I had not. In what way?’

‘Well, the house is… unkempt… ill-cared-for; there are hardly any servants except horrible Mr Grunthorpe. And the garden — oh, the garden is heartbreaking. Such lovely plants and everything overgrown and neglected.’

He pushed away his chair and rose, the simple gesture taking on an extraordinary sense of violence, and moved across to where the fig tree leaned its branches over the terrace wall.

‘He had no right,’ she heard him murmur. ‘Not the garden…’ and for a moment he leaned his head against the smooth grey bark as if in unutterable weariness.

‘There was no need for that,’ he said, coming back to stand behind his chair. ‘My father left enough.’

‘Your father?’

‘My father was General Brandon. I am his son by his second marriage.’ He made an impatient gesture. ‘I don’t wish to go into that; I simply want to know why you have come to tell me all this. Why you, Harriet?’

‘Because of Henry.’

She was looking down, her head bent over the table, and missed the whitening of his knuckles as he grasped the chair-back, the shock that passed over his face.

Henry! As clearly as if he stood before him, Rom saw the smug pale face of his hated step-brother. Henry who had cheated him, betrayed him… who had stood smirking down at Isobel in the Orangery on that last day…

‘Yes, it was because of Henry,’ said Harriet. ‘I met him there when I went on a visit and I liked him so much. I loved him, I think.’ Her voice was ineffably tender; she made the gesture that women make when they express a sensuous surrender, cupping her hands round her own throat. ‘I wanted to help him.’

Rom did not speak. His face as he struggled with the blow she had dealt him was that of a Tartar chieftain, foreign and cruel.

‘Henry thought you might be here.’ Her voice was still dreamy with remembrance. ‘Because of the book you left behind with Nannie. Because you were always talking about the Amazon. He said, if I found you, would I ask you to come back. He thought you would be able to make everything all right again at Stavely. It was because of him, really, that I came,’ finished Harriet. ‘He made me brave.’

Only now did she look up. ‘What is it?’ she faltered. ‘What have I done?’

Rom was in control again. She had spoken for scarcely two minutes, yet in that time he had torn from his heart every feeling she had aroused; every hope that loneliness was ended. Only his anger remained — the anger with which, since his mother’s death, Rom had responded to loss.

‘Let me get this clear, Harriet. When you stayed behind last night, it was to tell me what you have told me now? It was to plead for Henry Brandon?’

‘Yes.’ Separated by fear from the common-sense which might have saved them both, stupid with bewilderment, she could only repeat, ‘I wanted to help him, is that so terrible? What have I done?

‘Nothing,’ he said. ‘You have done nothing. On the contrary, you have fulfilled your mission excellently. And now please go back and tell your protégé that I will see him in hell before I raise a finger to save Stavely. Just tell him that.’ He stood for a moment looking down at the fruit on the table with the ghost of a smile. ‘How wise you were not to open it,’ he said, picking up the pomegranate. ‘Not a single seed eaten. No reason ever to return.’

He balanced the golden orb for a moment on his hand — then threw it with all his strength in a high arc over the wall. ‘Pedro will take you back in the car,’ he said — and without a goodbye, without a handshake, was gone.

Two days later the redoubtable Olga fell ill. Since their arrival Dubrov had relentlessly patrolled the Metropole dining-room, forbidding anyone to drink unboiled water on pain of instant dismissal; he had handed out quinine, had himself checked the mosquito netting in the girls’ bedrooms and confiscated all fruit bought from barrows in the street. Even so, several members of the company had complained of stomach pains and with three days of the first week’s run of Swan Lake still to go, Olga was definitely too ill to dance.

‘Seventeen swans again,’ said Grisha gloomily.

But more serious than the inconvenience of rearranging the choreography for the corps was the need to rehearse a new ‘Odette-at-the window’. For Olga had been the girl who, dressed as the Swan Queen in her white tutu and glittering crown, flutters at the window in such anguish to show the Prince that he has been tricked — that the girl he has just promised to marry is not the real Odette, but an usurper.

It is a short scene, scarcely three minutes in all — yet it is rare for anyone to leave the theatre without recalling the image of that beseeching, moonlit figure, exiled from happiness and love.
