And worse was the insistent buzzing feeling beneath her skin, the one that said, Forget friends, put your hand on his thigh, press your lips to his throat, tear off his clothes and kiss him all over-go on, you know you want to, until Perdita was quivering and fizzing with tension.

Trying not to show it was exhausting. Torn between needing to see him and not wanting Ed to know how much, Perdita became increasingly grouchy and on edge. It was so tiring having to be careful the whole time. She had to be careful not to touch him, even by accident, careful not to look directly in his eyes in case he saw how much she really wanted to touch him. She had to be careful to think about Nick and how much she had suffered. Careful not to remember how good it had felt when Ed had kissed her.

It was getting to the point where Perdita was beginning to wonder if it would be easier in the long run not to be friends at all. Between feeling tense about Ed and worrying about her mother, she seemed unable to relax at all, and she had even contemplated backing out of the party to launch the garden project-until Millie had got wind of her reluctance and informed her that, short of being carted off to hospital in an ambulance, she was most certainly going to attend.

‘Your mum’s much better-you told me that yourself-so don’t even think of that as an excuse!’ she told Perdita roundly. ‘You need a night off. How long is it since you dressed up and had a good time?’ she demanded. ‘Besides, I need you to chat up potential sponsors and tell them how brilliant the project is.’ Millie glanced at her friend. ‘Ed’ll be there,’ she added, studiedly casual.

‘I know.’ Faced with some very uncomfortable questioning about why exactly she didn’t want to go, Perdita gave in and promised that she would turn up.

So here she was, standing at the entrance in a scarlet sheath dress that she had worn for Dutch courage and a pair of high-heeled strappy sandals that Millie always referred to with mocking coyness as her ‘make love to me’ shoes.

‘You look fantastic!’ Millie grabbed her before holding her at arm’s length so that she could study her critically. ‘That colour is so good on you.’ She sighed enviously. ‘There won’t be a man here who’ll be able to keep his eyes off you!’

‘Come on, Millie, I’m forty. You know we’re invisible now!’

‘No way are you invisible in that dress,’ said Millie with a frank look. ‘Or in those shoes, come to that. Who are you wearing them for?’

‘I don’t know what you mean,’ said Perdita stiffly.

‘Ed?’

The hateful colour rose in Perdita’s cheeks. ‘Of course not! I’ve told you, we’re just friends.’

But why was he standing so close to Grace?

‘I’m glad you said that.’ Millie leant forward confidentially. ‘I did want to check it was OK with you before I put my seduction plan into operation.’

‘What seduction plan?’

‘The seduction of Edward Merrick!’ She struck a dramatic pose and Perdita’s eyes narrowed.

‘What?’

Millie opened her eyes, all innocence. ‘Well, you did say I was welcome to him,’ she reminded Perdita. ‘You’re always going on about how you and he are just good friends, so I thought I might as well have a go.’ She glanced at her friend to check her reaction. ‘Of course, Grace is probably in with a better chance than me. She’s beautiful, isn’t she?’

She was. Perdita looked over to where Grace was standing next to Ed. She was laughing and her eyes looked huge and luminous in her pale face. A cold hand closed about Perdita’s heart.

Millie watched her expression with some satisfaction. You didn’t need to be an old friend to see that Perdita didn’t like what she saw at all.

‘Of course, I can’t compete with Grace in the looks department, but it’s possible he might prefer somebody with a Good Sense Of Humour. What do you think?’ she asked Perdita. ‘Am I in with a chance? I mean, you’re his friend, you must know what he likes.’

‘I’ve no idea,’ snapped Perdita. ‘I’m going to get a drink,’ she told Millie and stalked away, unaware that her friend was grinning as she watched her go.

Passing a waitress circulating with a tray of drinks, Perdita snatched a glass and practically downed it in one before she could feel her fingers uncurling. The truth was that she hated the idea of Ed getting together with either Millie or Grace.

Maybe that would be the answer, though? She considered the matter. Surely it would change things if she knew that he was involved with someone else? Perhaps that was what she needed to stop thinking about him like this. Perhaps then they really could be friends if she knew that the only thing standing between them being anything else was more than her strength of will.

In fact, thought Perdita, downing the rest of her glass, what she really needed was to get involved with someone else herself. Yes, that was it! Helping herself to another glass, she put on her best smile and proceeded to mingle with a vengeance.

She wasn’t actually expecting to meet anyone. As she had told Millie, she was getting used to the fact that women over forty were practically invisible, and the room was full of much younger and prettier women. Still, it was gratifying to see appreciation warm the eyes of more than one man, and to discover that, even though she had passed the dreaded four-oh milestone, she could still flirt and be flirted with.

And it was even more gratifying to glance towards Ed and see that he was losing his famous calm and beginning to look positively thunderous.

The closer his brows drew together, the more Perdita flirted, unable to decide whether she was enjoying herself or feeling wretched. The strain was taking its toll on her, though. She was standing chatting with rather forced animation to the director of a local building contractor when she glanced over his shoulder and found herself looking straight into grey eyes she would have recognised anywhere, and something inside her unlocked. It was like being snapped back into consciousness out of a dream.

What was she doing? She looked back at her companion. He seemed a perfectly nice, attractive, friendly man, and in other circumstances she might have enjoyed talking to him, but this was now and she didn’t want to be with him. She only wanted to be with Ed.

Meeting his gaze once more, Perdita had the strangest sensation that the world was receding behind an invisible barrier. The party continued, people were talking and laughing and lifting their glasses, but the sound was muffled, distant, and there was nothing real but Ed and the expression in his eyes, which had sharpened to a new intensity as she looked back at him.

Then he was pushing his way through the crowds towards her. ‘Excuse me,’ he said to her puzzled companion as Perdita stood numbly watching him. ‘I just need a word with Perdita outside.’

Taking her hand, he practically dragged her to the entrance, where a knot of smokers had escaped and were puffing desperately on their cigarettes. Ed muttered under his breath at finding yet more people around and strode round to the shadows at the side of the old building, Perdita stumbling unresisting after him. Barely out of sight of the smokers, he stopped abruptly and, without a word, pressed her up against the brick wall and kissed her.

It was a furious kiss. His hands were hard, his lips demanding, but Perdita met him halfway, kissing him back as if she were equally angry at the time they had wasted, time they could have been kissing like this. There wasn’t even token resistance in her response, only a dazzling explosion of relief that she was in his arms at last, that she could kiss him again, hold him again, run her hands over his back and feel that he was real and warm and solid.

Gasping his name, she blizzarded kisses along his jaw when they broke for breath and Ed gave a shaky laugh.

‘God, Perdita, what have you done to me?’ he asked in a voice ragged with desire. ‘I’m too old to be losing control like this!’

He held her face between his palms. ‘You’re driving me mad,’ he told her between kisses. ‘I can’t do this any more, I can’t just be friends…’

‘I know…I know…’ she whispered, her lips pressing hungrily against his throat.

Ed gave a great sigh and rested his forehead against hers. ‘What are we going to do?’ he asked despairingly. ‘I can’t get rid of my kids, Perdita, but I can’t stand not being able to touch you either…I haven’t known what to do with myself these last couple of weeks, and tonight…tonight Millie was the last straw.’

‘Millie?’ Perdita drew back and looked at him with a puzzled frown.

‘I think she did it deliberately,’ he told her. ‘Whenever I turned round, there she was, pointing out how fantastic you look and how pleased she is that you’re starting to show an interest in men again after being so hurt by Nick, and had I noticed how men were looking at you?’ Ed gave a bark of mirthless laughter. ‘Of course I’d noticed! It seemed like I was the only one who had to treat you like a friend, and then you looked straight at me and I just snapped…It’s a very long time since I’ve been reduced to dragging a woman out of a party so that I could kiss her!’

Perdita couldn’t help smiling. ‘Millie’s been playing a dark game,’ she said. ‘She told me that she was going to try and seduce you, and no doubt she could see perfectly well that I didn’t like that idea at all!’

‘She certainly didn’t try any seduction. She was too busy needling me about you.’ Ed’s smile faded as he twined her dark hair around his fingers so he could hold her head still and look deep into her eyes.

‘What are we going to do? I know why you don’t want to get involved with a father, Perdita, but there’s more than friendship between us, you know there is.’
