'Give it to me!' I say, and grab the phone out of Jemima's hand, my heart thumping. 'Hi,' I say, in as curt a tone as I can muster.
'Emma, it's me,' comes Jack's familiar voice, and with no warning, I feel a rush of emotion which almost overwhelms me. I want to cry. I want to hit him, hurt him …
But somehow, I keep control of myself.
'I never want to speak to you again,' I say. I switch off the phone, breathing rather hard.
'Well done!' says Lissy.
An instant later the phone rings again.
'Please, Emma,' says Jack, 'just listen for a moment. I know you must be very upset. But if you just give me a second to explain—'
'Didn't you hear me?' I exclaim, my face flushing. 'You used me and you humiliated me and I never want to speak to you again, or see you, or hear you or … or …'
'Taste you,' hisses Jemima, nodding urgently.
'… or touch you again. Never ever. Ever.' I switch off the phone, march inside and yank the line out of the wall. Then, with trembling hands, I get my mobile out of my bag and, just as it begins to ring, switch it off.
As I emerge on the balcony again, I'm still half shaking with shock. I can't quite believe it's all ended like this. In one day, my entire perfect romance has crumbled into nothing.
'Are you OK?' says Lissy anxiously.
'I'm fine. I think.' I sink onto a chair. 'A bit shaky.'
'Now, Emma,' says Jemima, examining one of her cuticles. 'I don't want to rush you. But you know what you have to do, don't you?'
'What?'
'You have to get your revenge!' She looks up and fixes me with a determined gaze. 'You have to make him pay.'
'Oh no.' Lissy pulls a face. 'Isn't revenge really undignified? Isn't it better just to walk away?'
'What good is walking away?' retorts Jemima. 'Will walking away teach him a lesson? Will walking away make him wish he'd never crossed you?'
'Emma and I have always agreed we'd rather keep the moral high ground,' says Lissy determinedly. '"Living well is the best revenge." George Herbert.'
Jemima stares at her blankly for a few seconds.
'So anyway,' she says at last, turning back to me. 'I'd be delighted to help. Revenge is actually quite a speciality of mine, though I say it myself …'
I avoid Lissy's eyes.
'What did you have in mind?'
'Scrape his car, shred his suits, sew fish inside his curtains and wait for them to rot …' Jemima reels off instantly, as though reciting poetry.
'Did you learn that at finishing school?' says Lissy, rolling her eyes.
'I'm being a feminist, actually,' retorts Jemima. 'We women have to stand up for our rights. You know, before she married my father, Mummy went out with this scientist chap who practically jilted her. He changed his mind three weeks before the wedding, can you believe it? So one night she crept into his lab and pulled out all the plugs of his stupid machines. His whole research was ruined! She always says, that taught Emerson!'
'Emerson?' says Lissy, staring at her in disbelief. 'As in … Emerson Davies?'
'That's right! Davies.'
'Emerson Davies who nearly discovered a cure for smallpox?'
'Well, he shouldn't have messed Mummy about, should he?' says Jemima, lifting her chin mutinously. She turns to me. 'Another of Mummy's tips is chilli oil. You somehow arrange to have sex with the chap again, and then you say. "How about a little massage oil?" And you rub it into his … you know.' Her eyes sparkle. 'That'll hurt him where it counts!'
'Your mother told you this?' says Lissy.
'Yes,' says Jemima. 'It was rather sweet, actually. On my eighteenth birthday she sat me down and said we should have a little chat about men and women—'
Lissy is staring at her incredulously.
'In which she instructed you to rub chilli oil into men's genitals?'
'Only if they treat you badly,' says Jemima in annoyance. 'What is your problem, Lissy? Do you think you should just let men walk all over you and get away with it? Great blow for feminism.'
'I'm not saying that,' says Lissy. 'I just wouldn't get my revenge with … chilli oil!'
'Well, what would you do then, clever clogs?' says Jemima, putting her hands on her hips.
'OK,' says Lissy. 'If I was going to stoop so low as get my revenge, which I never would because personally I think it's a huge mistake …' She pauses for breath. 'I'd do exactly what he did. I'd expose one of his secrets.'
'Actually … that's rather good,' says Jemima grudgingly.
'Humiliate him,' says Lissy, with a tiny air of vindication. 'Embarrass him. See how he likes it.'
They both turn and look at me expectantly.
'But I don't know any of his secrets,' I say.
'You must do!' says Jemima.
'Of course you do!'
'I don't,' I say, feeling a fresh humiliation. 'Lissy, you had it right all along. Our relationship was completely one-sided. I shared all my secrets with him — but he didn't share any of his with me. He didn't tell me anything. We weren't soulmates. I was a completely deluded moron.'
