But in the end, with Nick, she hadn’t been able to accept it any longer. Was it too much to expect that, just occasionally, she could have come first? That he would make time for her, rather than taking it for granted that she would fit in around him and the children? That he would make her feel loved and wanted and not just an extra pressure for him to deal with?

Apparently it had been. Pushed to the limit, Perdita had steeled herself to issue an ultimatum. Give me the attention I deserve or I leave. And Nick had chosen to let her go.

It was just as well Ed’s phone had rung when it did, she told herself. Otherwise it would have been too late. They would have come back to the flat, they would have made love, and that would have been it. It would have been impossible to pretend that he didn’t really mean anything to her then. And that would have been a terrible mistake.

No! cried her body, strumming with frustration. No, it wouldn’t. It would have been worth it!

But Perdita’s head knew better.

So she was ready when Ed came to find her in her office on Monday. He had rung several times on Sunday but she wouldn’t answer the phone and made sure that she went out with Rick to get her out of temptation’s way that evening.

‘About the other night…’ he began, but Perdita interrupted him before he could go any further.

‘It’s fine, Ed. There’s no need to explain anything. I understand perfectly.’

Ed was daunted by her bright manner. It was hard to believe that this brittle woman was the same one who had been so soft and warm and responsive on Saturday evening. He had been reeling ever since. There was normally such a refreshing astringency about Perdita and he had been totally unprepared for how sweet she had been, and his body was still aching with frustration

If only Cassie hadn’t rung when she had…Ed could cheerfully have throttled his daughter when he’d picked her up. He hadn’t, of course, but he had been in an extremely bad mood, to which Cassie had taken exception, and they had argued all the way home, which was not the way he had hoped to end the evening.

Now he couldn’t stop thinking about Perdita. The memory of her and that startling sweetness was like fire in his blood, and he had longed to see her again. He had been hoping that he could have seen her yesterday, but she had obviously been out all day and he had found himself impatient and nervous as a teenager at the prospect of seeing her today.

Talking in her office wasn’t ideal, but surely they were close enough now for that not to matter? Something about her smile, though, was making him uneasy.

‘I thought…I hoped…that we could try again this evening,’ he said as he came into her office and closed the door behind him. ‘Cassie’s under strict orders to stay home tonight! Have you got time for a drink, at least?’

‘I don’t think so, Ed.’ Perdita had got to her feet when he’d appeared and now she bent over her desk to straighten some papers. The glossy hair swung down, hiding her face. ‘I thought about it yesterday and I think it’s better if we stick to a professional relationship.’

‘You don’t think it’s a bit late for that?’

When Perdita lifted her head, he could see that her cheeks were tinged with colour. ‘I’m sure we can manage to forget Saturday night,’ she said with some difficulty.

‘I’m not sure I’m going to be able to forget it,’ Ed said honestly.

Perdita swallowed and hugged her arms together the way she did when she was nervous, and it struck Ed how very familiar she was to him already.

‘I don’t think mixing business with pleasure is a good idea,’ she said uncomfortably, and he thrust his hands into his pockets, trying not to get angry. She was slipping away from him, and there didn’t seem to be anything he could do about it.

‘It felt like a very good idea on Saturday night,’ he reminded her, knowing that he was being unfair but unable to help himself. ‘Or are you going to pretend that you didn’t enjoy it?’

His voice was harsh and the colour in Perdita’s cheeks deepened painfully, but she met his eyes steadily enough.

‘No, I’m not going to pretend that, but I do regret it now. I would rather we were just friends.’

‘I’ve got enough friends,’ said Ed bitterly. ‘I don’t want you as a friend. I want you as…’

‘As what, Ed?’

He didn’t answer immediately. Unable to stand still, he went over to the window and looked out, his back to Perdita, his shoulders rigid. ‘You’re the first woman I’ve wanted since Sue died,’ he told her without looking at her. ‘I think…I thought…that we could have something good together.’

‘I’m sorry,’ Perdita said quietly. ‘I just don’t think it could work. Our lives are too different.’

‘Are they?’

‘You know they are. You’ve got three children who demand all your attention.’

‘Not all of it,’ he protested.

‘Almost all of it. When they’ve had the attention they need, and work has the attention it needs, how much would be left for me? Enough for a brief affair, maybe,’ she said, answering her own question, ‘or an occasional fling. I know, because I’ve been there before,’ she said. ‘I don’t want that again. I promised myself that if I have another relationship, it’ll be a proper one. I deserve more than being someone who just gets squeezed in every now and then between other commitments.’

‘I see.’ Ed turned from the window, bitterly disappointed. It had felt so good the other night, so right, that he couldn’t believe that she was pushing him away.

But he couldn’t argue with her. He was hardly going to propose marriage after one kiss, if that was what she wanted, he thought, disappointment feeding an anger that was so much easier to deal with than hurt. He would have to know her a lot better before he could be certain that she would the right stepmother for his kids, even if he was sure that she was right for him.

‘Well, there’s not much I can say, is there?’ he said. ‘Except I’m sorry. But of course I will respect your decision. You don’t need to worry about me hassling you to change your mind.’

That ought to make her feel better, oughtn’t it? Perdita thought. So why did she feel so awful?

‘I hope it won’t make it difficult working together,’ she said awkwardly.

A glimmer of a smile lightened Ed’s face. ‘Of course not,’ he said. ‘We’re both adults, Perdita. We should be capable of keeping our personal and professional lives separate.’

Easy to say, Perdita thought as the days passed. Doing it was another matter. It was very hard when her heart leapt at the mere mention of Ed’s name in a meeting, when the sound of his voice set her heart hammering and a mere glimpse of him walking down the corridor was enough to make her hollow with desire.

And it wasn’t just at work that she had to be on her guard. There was always the chance that she would bump into him when she visited her mother. She never did, but was constantly on edge in case he appeared.

Every week, she turned up dutifully at the garden project. It made her feel better to know that her colleagues were also required to contribute to the community in some way and, when she heard about some of the projects the others were involved in, Perdita couldn’t help thinking that she was better off where she was. She and Tom cleared and dug and dug some more and, although she grumbled as a matter of form, she didn’t mind it nearly as much as she said she did. The more often she met Grace, the more she liked her, and it was a chance to catch up with Millie too, who had thrown herself into her new job with gusto.

There was something surprisingly satisfying about hard physical labour too. Perdita dug the heavy clay soil until her back ached, but in lots of ways it was a welcome respite from thinking about Ed or worrying about her mother.

Being with Tom was bittersweet, a constant reminder of Ed, but the closest she could get to him too. Tom was a restful person to work with. He was quiet, uncommunicative even, and the exact opposite of Perdita in many ways, but they made a good team. He might be sullen with his father or at college, but never with Perdita, who liked his quiet sense of humour and the sense of self-containment obviously inherited from his father. If he was still guilty of a “bad attitude” she at least could see no evidence of it.

After the first time, when Ed had picked him up, Tom had to make his own way home from the project and, as she was usually going to see her mother anyway, Perdita would give him a lift. She was never sure if she longed to see Ed or dreaded bumping into him on these occasions. Tom was frustratingly taciturn about life at home so Perdita gleaned little from him, although he did volunteer once that Ed had been in a filthy mood ‘for weeks now’.

It seemed that she wasn’t the only one suffering then. Again and again, Perdita told herself that she had done the right thing, but she couldn’t stop thinking about that kiss down by the river. She replayed it endlessly in her head and even when she managed to think about something else, like work, it was always there, simmering at the edge of her consciousness, ready to flare up into vivid memory at the slightest provocation: the sound of rain on an umbrella, the smell of the river, the sight of Ed’s name on a report. Perdita was torn between wishing that she could rewind time to before Cassie’s call and congratulating herself on her narrow escape.

‘I just wish that I could forget it,’ she sighed to Millie one evening over a bottle of wine. ‘All I want is to not think about it any more.’

She should have been more careful what she wished for, Perdita thought wearily a few days later. Her mother caught an infection that proved stubbornly resistant to antibiotics and she grew alarmingly weak. For the next fortnight, Perdita had no time to think about Ed as she dealt with doctors and ferried her mother to and from hospital for tests.
