‘Mistresses?’ she whispered, a sickening vision of a lifetime of humiliation unfolding before her.

‘Of course,’ her mother replied, stroking her hand soothingly. ‘You are not blind. You know that is what men do. All men,’ she said grimly, her thin lips compressing until they were almost white. ‘Just as soon as they can afford it.’

Heloise’s stomach turned over at the implication of her mother’s words. Even her papa, who behaved as though he was deeply in love with her mother, must have strayed.

‘If he is very considerate of your feelings he will conduct his affairs discreetly. But I warn you, if you make any protest, or even show that you care, he will be most annoyed! If you wish him to treat you well, you must not place any restrictions on his little divertissements.’

‘I have already informed him that I will not interfere with his pleasures,’ Heloise replied dully. And when she had told him that she had meant it. But now the idea that he could hasten to the arms of some other woman, when he could barely bring himself to allow her to lay her hand upon his sleeve, was unbelievably painful. Rising to her feet swiftly, she went to the open armoire. ‘What about the grey shot silk?’ she said, keeping her face carefully averted from her mother. ‘I have not worn that for some time. I don’t think His Lordship has ever seen me in it.’

Heloise did not particularly like the dress, for it had bad associations. The first time Du Mauriac had asked her father if he might pay his addresses to his oldest daughter, he had been so proud that she had captured the interest of a hero of France that he had sent her to the dressmaker with the instruction to buy something pretty to wear when her suitor came calling. She had been torn. Oh, how pleasant it had been, to be able to go and choose a gown with no expense spared! And yet the reason for the treat had almost robbed her of all joy in the purchase. In the end she had not been able to resist the lure of silk, but had chosen a sombre shade of grey, in a very demure style, hoping that Du Mauriac would not think she was trying to dress for his pleasure.

‘It is not at all the sort of thing Felice would have worn,’ her mother remarked, shaking her head. ‘But it will do for you. I shall get it sponged down and pressed.’ She bustled away with Heloise’s best gown over her arm, leaving her to her solitary and rather depressing reflections.

He had never seen her dressed so well, Charles thought with approval, when he came to collect her that evening. The exquisitely cut silk put him in mind of moonbeams playing over water. If only her eyes did not look so haunted. He frowned, pulling up short on the verge of paying her a compliment.

For the first time it hit him that she did not really wish to marry him any more than he wished to marry her. And she looked so small and vulnerable, hovering in the doorway, gazing up at him with those darkly anxious eyes.

She needed solid reassurance, not empty flattery.

Taking her hand in his, he led her to the sofa.

‘May I have a few moments alone with your daughter before we go out?’ he enquired of her parents. They left the room with such alacrity he was not sure whether to feel amused at their determination to pander to his every whim, or irritated at their lack of concern for their daughter’s evident discomfort.

Heloise sank onto the sofa next to him, her hand resting limply in his own, and gazed up into his handsome face. Of course he would have mistresses. He was a most virile man. She would just somehow have to deal with this crushing sense of rejection the awareness of his infidelity caused her. She must learn not to mind that he frowned when he saw her, and stifle the memories of how his eyes had lit with pleasure whenever Felice had walked into a room.

‘Heloise!’ he said, so sharply that she collected he must have been speaking to her for quite some time, while she had not heard one word he had said.

Blushing guiltily, she tried to pay attention.

‘I said, do you have the ring?’

Now he must think she was stupid, as well as unattractive. Her shoulders drooping, she held out her left hand obediently.

‘Hell and damnation!’ he swore. ‘It’s too big!’

‘Well, you bought it for Felice,’ she pointed out.

‘Yes, and I would have bought you one that did fit if only you’d told me this one didn’t! Why in God’s name didn’t you tell me, when I raised the subject this afternoon, that this ring was not going to be any good?’

‘Because I didn’t know it wouldn’t fit. Although of course I should have known,’ she ended despondently. Felice had long, strong, capable fingers, unlike her own, which were too slender for anything more strenuous than plying a needle or wielding a pencil.

‘Do you mean to tell me that you had an emerald of this value in your possession and you were never tempted to try it on? Not once?’

‘Oh, is it very valuable, then?’ She looked with renewed interest at the jewel which hung from her ring finger. In order not to lose it, she knew she was going to have to keep her hand balled into a fist throughout the evening. ‘I was not at all convinced it would get me all the way to Dieppe. Even if I’d managed to find a jeweller who would not try to cheat me, I fully expected to end up stranded halfway there.’

Her reference to her alternative plan of escaping Du Mauriac turned his momentary irritation instantly to alarm. He would do well to remember that he held no personal interest for her for his own sake at all. He was only providing the means, one way or another, for her to escape from an intolerable match with another man.

‘Well, you won’t be running off to Dieppe now, so you can put that notion right out of your head,’ he seethed. Damn, but he hoped her distress was not an indication she was seriously considering fleeing from him!

Though he could see she was scared as hell of him right now. And no wonder. She had entrusted him with her entire future, and all he could do was berate her over the trifling matter of the fit of a ring!

‘Come, now,’ he said in a rallying tone. ‘We struck an honest bargain this morning. It is in both our interests to stick with it.’ He took her hands between his own and gave them what he hoped was a reassuring squeeze. ‘We are in this together.’

Yes. She sighed. And so was Felice. He would never be able to keep from comparing her, and unfavourably. Just look at the way he was coaxing her out of the sulks in that patronising tone, as though she were a petulant child.

‘It is easier for you,’ she began. He was used to disguising his feelings behind that glacial mask he wore in public. But she had never been any good at dissembling.

‘Why do you suppose that?’ he said harshly.

‘Because I won’t know what to say to people!’ she snapped. Had he forgotten already that she had told him she was hopeless at telling lies?

‘Oh, come,’ he scoffed. ‘You ran on like a rattle in my drawing room this morning!’

‘That was entirely different,’ she protested. ‘It does not matter what you think.’ They were co-conspirators. She had no need to convince him she was anything other than herself.

Charles swiftly repressed the sharp stab of hurt these words inflicted. Why should he be bothered if she did not care what he thought of her? It was not as if she meant anything to him, either. He must just accept that playing the role of his fiancée was not going to be easy for her.

‘Very well,’ he nodded, ‘you need not attempt to speak. I will do all the talking for us both. Providing—’ he fixed her with a stern eye ‘—you make an attempt to look as though you are enjoying yourself tonight.’

‘Oh, I am sure I shall—in my own way,’ she assured him.

She loved studying how people behaved in social situations. Their posturing and jostling both amused and inspired her with ideas that went straight into her sketchbook the minute she got home.
