Only now, standing with her hands folded across her chest so that what was happening inside her could not escape and make people recoil from her, she wondered if it could be done. If this beast tearing at her entrails could be transformed into those moments of high art when Odette lets her fingertips run lightly down the Prince’s arm before she vanishes for ever into the lake. How many years would have to pass? How many aeons?

‘’ariette, you must eat!’ scolded Marie-Claude, coming to find her as she always did and taking her down to the dining-room — and at two she was back with Grisha, welcoming the ache in her limbs, the soreness, which people who did not understand were stupid enough to confuse with pain.

So the ship steamed eastwards and Harriet worked and pledged herself to make it come at last: the day when, contained in the iron framework of a flawless technique, she could reveal to those who watched her the heartbreak and the glory of an immutable love.

Four weeks after they left Brazil, punctual to the hour, the Lafayette steamed into Cherbourg. Harriet had scarcely thought of Cambridge or her home and she walked unthinkingly off the ship with her friends, bound for the custom sheds and the train to Paris.

Waiting at the bottom of the gangway — black-clad, menacing, flanked by two gendarmes with truncheons — stood her father and her aunt.

Harriet had been locked in her attic for nearly a month. Her clothes had been removed; she was conveyed to and from the bathroom by Aunt Louisa or those of the Trumpington Tea Circle ladies who came to take over when Miss Morton had to go shopping or merely needed a break. A doctor had been to examine her — not the old family doctor who had once recommended dancing classes, but a new man suggested by Hermione Belper — and had confirmed the Mortons’ worst fears. Pending further treatment of the unfortunate girl, Dr Smithson had given instructions for her to be kept in a darkened room and on a meatless diet to avoid over-stimulation — instructions which Louisa obeyed meticulously, feeding her niece mostly on semolina and rusks of oven-baked stale bread.

The purpose of this regime was reasonable enough: to break Harriet’s will, to make her understand the enormity of what she had done, and to confess it.

‘And then?’ asked Louisa as the days passed and Harriet remained silent. ‘What is to be done with her then?’ She had enjoyed the drama of the original recapture and imprisonment, but the daily task of keeping Harriet guarded fell on her, and the whispers in the town — the suggestion that the Mortons had gone too far in inflicting punishment — were far from pleasant.

‘We shall see,’ Professor Morton had replied. Obsessed with the idea of a grovelling, weeping daughter begging for mercy, he could think no further than Harriet’s utter subjugation.

In deciding how best to deal with Harriet, the Mortons were under the disadvantage of knowing nothing of her life in Manaus, for Edward Finch-Dutton, on whom they had relied, seemed to have disappeared. It was not Harriet’s former suitor who had informed them that she was arriving in Cherbourg, but an anonymous well-wisher who had been kind enough to cable St Philip’s from Manaus.

And Harriet would say nothing. She was willing only to apologise for having caused them anxiety by running away, and for nothing else.

‘I was happy there,’ she had said at the beginning. ‘I did nothing of which I am ashamed. It was the best part of my life and I would as soon apologise for breathing.’

And incredibly the weeks of confinement, the near-starvation, the appalling monotony — for they had taken away her books — had not weakened her resolution.

‘The name of your seducer!’ Professor Morton yelled at her on the rare occasions when he visited his daughter. ‘Assuming there was only one!’

But she had shaken her head and as day followed wretched day she neither broke down nor admitted her wrong.

Harriet endured because she had been loved by Rom. This honour had been accorded her, this ultimate benison, and she must not let them break her because to do so would be to denigrate his love.

So she kept herself sane and she did it by remembering. Not a haphazard wallowing in past happiness, but a disciplined, orderly progression through the rooms of Follina, through its gardens… along the banks of the river. Waking hungry in her cold and dismal room, Harriet, in her mind, rose from the cloud-netted bed where Rom still slept, felt the softness of the carpet beneath her feet… took three steps — exactly three — to the brocaded chair to trace the pattern of the golden fleur de lys… read the titles of the books on the low table: The Collected Works of John Donne; The Stones of Venice; The Orchid Grower’s Manual… moved to the window to draw aside the curtains and name, with the same rigorous precision she had once accorded her work at the barre, the plants that grew on the terrace beneath.

While she could do this — while she could drift in the Firefly past the bank where the otters played and see the sun bittern fly into the light — they could not touch her, and knowing she had to keep well so as to garner these memories, to make them part of her for ever, she ate every morsel of the food she was given and kept her muscles active with exercises as she well knew how to do.

And so the days passed and nothing the Mortons could do deflected her, though her stricken eyes seemed to grow ever larger in her face. Then, during the fifth week of her incarceration, she woke as usual and in her mind walked as usual across Rom’s room, drew aside the curtains, turned to cross the Persian rug so as to make her way back to the bed where he waited… and found that she could not remember the pattern of that rug. She had known it would be hard to remember, but she had studied it so carefully — so very carefully. Was it the outer border that was amethyst, with diamonds and zig-zags of bronze? Or was it the pearl-grey rim with its stylised flowers that came first? Desperate, she sat up in bed, her heart pounding. She had to remember, she had to! If she could forget one thing, she could forget it all — she could forget even Rom, and then there would be nothing left to live for in the world.

But the pattern would not be recalled. In her exhausted brain shapes and colours swam in an indistinguishable blur and whatever she did she could not reassemble them.

It was Hermione Belper who came that day to remove Harriet’s luncheon tray, and when she came down again she had good news for Louisa, who was returning from the shops.

‘She is weeping uncontrollably, Louisa — and she has not touched her food. It seems her spirit is broken at last. How thankful you must be!’

And the Mortons were thankful. But if Harriet now lay listlessly on the pillow and showed none of her former defiance, she still did not speak of her time in Manaus and she was growing so thin that it was not easy to see how she could, as it were, be ‘produced’ again in public. Moreover they themselves were being subjected to an increasing amount of unpleasantness. It was easy enough to discount the smear campaign of a woman like Madame Lavarre, but when the Provost of St Anne’s crossed the road rather than speak to the Professor, the Mortons were increasingly compelled to seek ways out of their dilemma.

It was at this point — just two weeks before the beginning of the Michaelmas term — that the Professor came home in a state of more than usual indignation.

‘Do you know who I met today? Edward Finch-Dutton! He was creeping round the walls of the Fountain Courtyard and trying to avoid me, I’m sure.’

‘Good heavens! But why has he not been in touch with us?’

‘I have no idea. Apparently he tried to bring Harriet back and it went wrong. He had a black eye and his nose was covered in sticking-plaster; I can only conclude that he has taken to the bottle. But I will tell you this, Louisa. I asked him what had made him send that second cable and he said it was because Harriet came out of a cake. In her underclothes.’ And as Louisa stared at him, speechless with incredulity: ‘That’s what he said. In her underclothes. Then he mumbled some nonsense about her perhaps not having meant any harm and bolted. I tell you the fellow was drunk; he will have to resign his Fellowship, no doubt about that.’

But the news had given Louisa her cue. ‘Bernard, don’t you think we ought to face the fact that Harriet is seriously unbalanced? I have thought so all along, but this really decides the matter. Isn’t it time we found a good institution where she can be helped? Homes for the mentally ill are extremely liberal these days: wholesome food, fresh air, basketwork… Dr Smithson knows of a specialist in London who has made a study of cases like hers. If Mr Fortescue certified that Harriet is not in her right mind, Smithson would second the diagnosis and her removal to somewhere suitable would follow automatically.’ And as the Professor still seemed to hesitate, she concluded, ‘I am thinking only of Harriet. She needs professional care and attention if she is to be healed. To refuse her that would be very selfish, would it not?’

This was a plea to which the Professor could scarcely be deaf. Dr Smithson accordingly was appealed to, and contacted his eminent colleague in Harley Street and it was arranged that Mr Fortescue would come down as soon as possible in order to examine Harriet.

After which, having got her way, Louisa was really quite kind to Harriet and sent up jam with her semolina and butter with her rusks, but for Harriet — slipping away into the shadows — these attentions came a little late.
