to be slotted around the location scenes for the next series. The studio is in Manchester.

      He had argued strongly that he had no choice, but when he’d added, ‘It’s not like Tilly wants this party, is it?’ it had been obvious how he really felt.

      A few days ago she’d watched him throw his suit bag onto the bed, whistling like a man who has no real cares. Like a man who thinks everything is fixed now. He’d been wearing only a turquoise towel around his middle and she could see a new softness there. The bedroom was filled with steam and the scent of the Czech & Speake aftershave she’d bought him for Christmas.

      He hadn’t even bothered with aftershave before his television career had taken off. Mark used to get his suits from John Lewis and he’d wear whatever ties and shirts Melissa put into his wardrobe. Now, despite putting on weight, he fusses about haircuts and Melissa has caught him patting under his chin and examining the line of his jaw in the mirror.

      Always an attractive man, with his dark brown eyes and the smattering of salt-and-pepper in his hair, as he approaches 44, he looks more comfortable in his skin than ever before.

      And look where that led us, she thinks.

      A wave of torpid, sapping exhaustion washes over Melissa now. For a second she longs to crawl under the sheets, close her aching eyes and allow darkness to press her into oblivion.

      Apart from Saskia, there are very few people downstairs who she actually wants to talk to. They are mostly parents she has met over the years or neighbours. The conversations with parents always felt like jousting matches, each jabbing the other with pointed boasts about their children. She doesn’t know any of Tilly’s boarding school friends, so these guests were mainly from primary school days. They had little in common anymore anyway.

      Sometimes she imagined what would happen if any of them found out about the things she had done. A cold chill creeps over her arms and she rubs them briskly. The chances of anyone from Before recognizing her in that picture must be infinitesimal. She has been told that her light green eyes are distinctive. But lots of people have light green eyes.

      Giving herself a mental shake, she arranges her face into one of friendly hospitality. She can do this. It’s really no different from putting on her make-up.

      As Melissa comes to the bottom of the stairs she hears a piercing, high-pitched laugh she doesn’t recognize.

      The party feels thinner somehow – like it has lost fat and heft, rather than individuals – and she wonders whether some guests have left without saying goodbye. Maybe she was upstairs for longer than she thought? Or maybe it is just that all the young people have decamped to the summerhouse at the bottom of the garden. She can hear the thump of music coming from there and hopes Tilly is finally enjoying herself.

      There’s that baying laugh again. Emerging onto the patio she spies Hester, talking animatedly to a couple from the tennis club, who regard her with blank expressions. The scene is so unexpected it takes a moment to make sense of it. Hester’s hair is sticking damply to her forehead and her eyes have a bright, unfocused glaze. Is she … drunk?

      The woman who once said, ‘Mind my French’, after using the word ‘bloody’ and who Mark once joked wears a chastity belt under her old-lady skirts? Hester, drunk?

      ‘Here she is!’ Hester trills as Melissa cautiously approaches.

      Gary and Sue meet her puzzled gaze and Sue raises an eyebrow, quizzically, at Melissa, barely stifling a smile.

      Melissa gives her a stricken look back.

      ‘I was just telling your friends Gary and … um … Thing, that I used to look after Tilly all the time when she was little. I was like an aunty to her, wasn’t I, Melissa? We’re all terribly proud of her now, aren’t we?’

      Melissa grimaces and tries to convey an apology with her eyes to Gary and Sue.

      ‘Well, you certainly helped me out once or twice,’ she says. ‘And yes, we are very proud of her.’

      Hester hiccups and then turns to look around the garden, her eyes narrowed.

      ‘Where did that Jess one go? I liked her. Although I’m not completely sure she isn’t one of those. Not that I care! Live and let live, I say. As long as they are not rubbing our noses in it.’

      Sue tuts.

      ‘Oh dear God,’ says Melissa under her breath.

      ‘Gosh, look at the time!’ says Gary, pretending to look at his watch, not very convincingly.

      ‘It’s Pimm’s o’clock!’ trills Hester and collapses into giggles, staggering slightly against Melissa, who takes hold of her arm.

      Hester leans into her. For a small woman, she feels surprisingly solid. Melissa is momentarily reminded of holding Tilly as a toddler; the dense heat of her compact body.

      ‘You seem to be having a good time, Hester,’ says Melissa tightly. ‘Have you had any water?’

      Hester hiccups and belatedly puts a hand over her mouth.

      ‘I’ve only had two drinks but I do feel a little squiffy. Perhaps I should have some of your lovely nibbles! I was just telling, um, Thing …’, Sue smiles primly but doesn’t help her out, ‘that I offered some of my scones but it seems you have done a wonderful job of catering. It’s all lovely! Darned if I can identify any of it, though!’

      At this she breaks into peals of laughter. Melissa realizes that she has never really heard Hester laugh properly before. The high-pitched seal bark hurts her head a little bit more.

      ‘Okay, maybe you should have a drink of water and something to eat, hmm?’ Melissa begins to steer her back into the kitchen, mouthing ‘sorry’ at Gary and Sue, who are already turning to each other and leaning in with conspiratorial grins.

      Nathan watches her with a small smile as she comes into the kitchen. Melissa privately thinks that Saskia panders to him far too much. He and Tilly seem to have some sort of awkwardness between them and Tilly has called him, ‘a bit of an airhead’.

      He’d even half come-on to Melissa at Christmas and she’d had to pretend it was all a joke. He certainly seems very amused by something as he studies Hester stumbling towards the table of food, which is now a wreck of weary salad leaves, smeared plates, and crumbs.

      She wishes they would all go home. She only had this party as a sort of ‘fuck you’; to prove to herself that Mark’s betrayal hasn’t destroyed her. She is a survivor. Not that any of them even knew about it, apart from Saskia. But it all feels so much more trouble than it is worth.

      Hester is now folding a mini pavlova into her mouth in one piece so cream dribbles from the corner of her lips. Melissa sighs and says, ‘Wait there,’ and goes to the sink. A woman she knows from the tennis club, Jennie, is nearby. She does a comical staggering motion and murmurs, ‘Gosh, she’s a bit worse for wear! Who on earth is that?’

      ‘My next-door neighbour,’ says Melissa in a low voice as water from the filter tap splashes noisily into the tall green glass. Normally she would add ice and some fresh mint but there’s no point wasting that on Hester. ‘She’s totally off her face, isn’t she? I didn’t even want her here but she sort of invited herself.’

      The other woman laughs. ‘She banged on to me earlier about being one of the family or something,’ she says. ‘I thought it was a bit strange when you’ve never mentioned her!’

      ‘Oh God,’ says Melissa with feeling, turning off the tap.

      ‘Well she’s certainly making up for lost time with the food now!’ says Jennie stifling another laugh.

      Melissa turns to see Hester cramming crisps into her mouth with a robotic regularity. She takes the water over and places it on the table next to where she stands.

      ‘Here,’ she says, no longer bothering to hide her irritation, ‘you’d better drink this and then maybe it’s
