The orchestra entered, then the conductor. To get Berthold to conduct the BBC Symphonia for the concertos was a real coup for the organizers. Heini, rehearsing with them in the morning, had been over the moon.

On Ruth’s other side, Leonie turned to smile at her daughter. She had come down from Manchester and meant to stay till the exams the following week. Her anxiety about Ruth, who was clearly unwell, was underlain by a deeper wretchedness for she knew that if Heini won it meant America and the idea of losing Ruth was like a stone on her chest.

‘You must not show it,’ Kurt had said. ‘You must want it. She’ll be safe there and nothing matters except that.’

Since March, when Hitler, not content with the Sudetenland, had marched into Prague, few people believed any more in peace.

The whole row was filled with Ruth’s friends and relations. Beside Pilly sat Janet and Huw and Sam. The Ph.D. student from the German Department was there, and Mishak and Hilda… even Paul Ziller had come and that was an honour. Ziller was very preoccupied these days; the chauffeur from Northumberland was pursuing him, begging to be heard — there was pressure from all sides for him to lead a new quartet.

It was hot in the hall with its domed roof. Leonie, dressed even at three in the afternoon like a serious concert-goer in a black skirt and starched white blouse, fanned herself with the programme. And now Daisy MacLeod came onto the platform with her dark hair tied back with a ribbon and her pretty blue dress and shy smile, and a storm of clapping greeted her. The Tchaikovsky suited her. She was very young; there were rough passages and once or twice she lost the tempo, but Berthold eased her back and the performance was entirely pleasing. Whether she won or not, she was assured of a career.

The applause was loud and prolonged, bouquets were carried onto the stage; the judges wrote things down and nodded. Ruth liked Daisy, liked her playing, but: ‘Oh, God, don’t let her win.’

And now the culmination of all those weeks of worry and work. Heini came on the platform with his light, springing gait; bowed. Ruth had searched the flower shops of Hampstead for the perfect camellia, Leonie had ironed each ruffle on his shirt, but the charm, the appealing smile, owed nothing to their ministrations. His platform manner had always been one of his strong points, and Ruth looked up at the box where Mantella sat with Jacques Fleury, the impresario, who as much as the judges held the keys to heaven or hell. Mantella was important, but Fleury was god — he could waft Heini over to the States, could turn him into a virtuoso and star.

Berthold raised his baton; the orchestra went into the tutti… the theme was stated gently by the violins, taken up by the woodwind…

And everybody smiled. Mantella had been right. The audience was ready for this music.

When the angels sing for God they sing Bach, but when they sing for pleasure they sing Mozart, and God eavesdrops.

Heini waited, looking down at the keys in that moment of stillness she had always loved. Then he came in, stating the theme so rightly, so joyfully… and she let out her breath because he was playing marvellously. Obviously he had been nervous only to the necessary degree: now he was purged of everything except this limpid, tender, consoling music which flowed through him from what had to be heaven if there was a heaven anywhere. He had performed this miracle for her the first time she heard him and she would never tire of it, never cease to be grateful. All her past was contained in the notes he played — all her life in the city she once thought would be her home for ever. No wonder she had been punished when she forsook that world.

The melody climbed and soared, and she climbed with it, out of her sadness, her wretchedness, the discomforts of her body… out and up and up. Ah God, if only one could stay up there; if only one could live like music sounded — if only the music never stopped!

The slow movement next. She was old enough now for slow movements, she was immemorially old. It must be possible to love someone who could draw such ravishment from the piano. And it was possible. She could love Heini as a friend, a brother, someone whose childishness and selfishness were of no account when set against this gift. But not as a man — not ever, now that she knew… and suddenly the platform, Heini himself, grew blurred in a mist of tears, for it was a strange cross that Fate had laid on her, ordinary as she was: an inescapable, everlasting love for a man to whom she meant nothing.

The last movement was a relief, for no one could live too long in the celestial gravity of the Andante — and here now was the famous theme! It would have to be a very unusual starling to have sung that melody, but what did it matter? Only Mozart could be so funny and so beautiful at the same time! Everyone was happy and Ziller was nodding his head which was important. Ziller didn’t like Heini, but he knew.

Then suddenly it was over and Heini rose to an ovation. People stamped and cheered; a group of schoolgirls threw flowers on to the stage — there were always schoolgirls for Heini — and in his box, Jacques Fleury had risen to his feet.

‘I’m sorry I said he was too long in the bath,’ said Leonie, dabbing her eyes. ‘He was too long, but I’m sorry I said it.’

He had to have won. There could be no doubt… not really.

But now Berthold returned, and the tall Russian, Selnikoff, to play the Rachmaninoff.

And, God, he was good! He was terrifyingly good, with the weight of his formidable training behind him and the outsize soul that is a Russian speciality.

Ruth’s nausea was returning. Please, God — oh, please… I’ll do anything you ask, but let Heini have what he so desperately wants.

The dinner, as always at Rules, had been excellent; they’d drunk a remarkable Chablis, and Claudine Fleury, in a little black dress which differed from a little chemise only on a technicality, had made Quin a much-envied man.

Now she yawned as delicately as she did everything. ‘That was lovely, darling. I wish I could take you back, but Jacques is here for another week.’

‘Of course, I quite understand,’ said Quin, managing to infuse just the right amount of regret into his voice. Claudine’s father was notoriously easy-going, but there is an etiquette about such things. She had rung him a few days earlier to suggest dinner before he left for Africa and he had been ready to take the evening any way it suited her, for he owed her many hours of pleasure, but the temporary return of Jacques Fleury to attend to business was not unwelcome.

‘How is Jacques? Has he snapped up any more geniuses?’

‘As a matter of fact, he has. He called just before I left. He’s signed up an Austrian boy — a pianist whom he’s going to bring to New York and turn into a star! There was some competition today; he wanted me to come, but three concertos in one afternoon — no thank you!’

‘He won, then, this Austrian?’

‘No. He tied with a Russian and he wasn’t too pleased, I gather. Jacques thinks the Russian is more musical, but you can’t do anything with Russians; they’re so guarded — whereas he can get the Austrian boy over almost straight away. He’s going to bring his girlfriend over too — apparently she’s very pretty and absolutely devoted… worked in some café to pay for Radek’s piano or something. Jacques thinks he can use that at any rate till they’re married; she photographs well! There was some story about a starling…’

She yawned once more; then stretched a hand over the table. ‘I suppose we won’t meet again before you go?’

‘No, I’m off in less than three weeks. And Claudine… thanks for everything.’

‘How valedictory that sounds, darling!’ Her big brown eyes appraised him. ‘Surely we’ll meet again?’

‘Yes. Of course.’

For a moment, he felt the touch of her fingertips, light as butterflies, on his knuckles. ‘I shall miss you, chéri. I shall miss you very much, but I think you need this journey,’ she said. ‘Yes, I think you need it badly.’

The news that Quin was leaving Thameside, which the Vice Chancellor received officially on the first day of the summer term, had affected Lady Plackett so adversely that Verena had been compelled to take her mother aside and make her acquainted with the real state of things.

‘There is no doubt, Mummy, that he means to take me to Africa, but the matter has to be a secret for the time being. I can trust you, I know.’

Lady Plackett had not been as pleased as Verena had hoped. It was a proposal of marriage that she wanted from Quin, not the use of her daughter as an unpaid research assistant. She was still busy bringing Thameside’s morals up to scratch and had managed to get two first-year students sent down who had been caught in flagrante in the gym, so that her daughter accompanying a man, however platonically, to whom she was not married, was far from agreeable. But Verena had always done what she wanted, and Lady Plackett, accepting that times had changed, continued to be civil to Quin and to invite him to the Lodge.

Verena’s preparations, meanwhile, were going well. She had acquired a sunray lamp; she had been to the Army and Navy Stores for string vests and khaki breeches; she rubbed methylated spirits, nightly, into her feet. Some people might have wondered why the Professor was taking so long to inform her of his plans, but Verena was not a person to doubt her worth, and if she had felt any uncertainty, it would have been quelled by Brille-Lamartaine whose increasingly fevered descriptions of the academic femme fatale who had ensnared Somerville fitted her like a glove.

Nevertheless, with the final exams only a week away, Verena felt she could at least give the Professor a hint. He had praised her last essay so warmly that it had brought a blush to her cheek, and the intimate discussion she had had with him on the subject of porous underwear seemed to indicate that the time for secrecy was past.

So Quin was invited to tea, and aware that it was his last social engagement with the Placketts, he set himself to please.

It was a beautiful early summer day, with a milky sky and hazy sunshine. The French windows were open; the view was one Quin had enjoyed so often in previous years when Charlefont was alive and the talk had been easy and unaffected, not the meretricious academic babble he had had to endure from the Placketts.

‘Shall we go out on to the terrace for a moment?’ suggested Verena, and he nodded and followed her while Lady Plackett tactfully hung back. Leaning over the parapet, Quin let his thoughts idle with the lazy river, meandering down to the sea.

‘You always live by water, don’t you?’ the foolish Tansy Mallet had said, and it was true that he lived by water when he could and was likely to die by it, for he still had his sights set on the navy.

But it was not Tansy he thought of now, nor any of the girls he had once known.

They had collected a lot of rivers, he and Ruth. The Varne which she had intended to swim with a rucksack… The Danube which had brought Mishak his heart’s desire… and the Thames by which they’d stood on the night he thought had set a seal on their love. Once more he heard her recite with pride, and an Aberdonian accent so slight that only a connoisseur could have detected it, the words which Spenser had penned to celebrate an earlier marriage. Had she known it was a prothalamium, a wedding ode, that she spoke, standing beside him in the darkness? Had Miss Kenmore told her that?

And suddenly Quin was shaken once more by such an agony of longing for this girl with her lore and her legends, her funniness and the dark places which the evil that was Nazism had dug in her soul, that he thought he would die of it.

It was as he fought it down, this savage, tearing pain, that Verena, beside him, began to speak, and for a moment he could not hear her words. Only when she repeated them, laying a hand on his arm, did he manage to make sense of her words.

‘Isn’t it time we told everyone, Quin?’ she asked — and he recoiled at the intimacy, the innuendo in her voice.

‘Told them what?’

‘That you are taking me to Africa? I know, you see. Brille-Lamartaine told me that you were taking one of your final students and Milner confirmed it. You could have trusted me.’

Horror gripped Quin. Too late he saw the trail of misunderstandings that had led to this moment. But he was too fresh from his images of Ruth to be civil. The words which were forced out of him were cruel and unmistakable, but he had no choice.
