He dug around in his pockets, ignoring the barely suppressed sighs and rolled eyes from those behind him and by some miracle from his inside jacket pocket and the bottom of his wallet he was able to scrape up cash for everything bar the onion bhajis. He counted it all out and she raised her eyebrows ostentatiously as she rang it up, and shoved the bhajis to one side, where they would doubtless be shoved back into a chiller cabinet some time later. Ed, in turn, shoved it all into a carrier bag that would give way even before he reached the car, and tried not to think about his mother.

He was cooking when Jess limped downstairs. At least, he had two plastic trays rotating noisily in the microwave, which was about as far as he had ever immersed himself in the culinary arts. She was wearing a towelling bathrobe and had her hair wrapped in a white bath-towel turban. He had never understood how women did that. His ex had done it too. He used to wonder if it was something women got taught, like periods and hand-washing. Her bare face was oddly beautiful.

‘Here.’ Ed held out a glass of wine.

She took it from him as if she barely noticed. He had started a fire, and she sat down in front of the flames, apparently still lost in her thoughts. He handed her the frozen peas for her foot, then busied himself with the rest of the microwave meals, following the instructions on the packaging.

‘I texted Nicky,’ he told her, as he stabbed the plastic film with a fork. ‘Just to tell him where we were staying.’

She took another sip of her wine. ‘Was he okay?’

‘He was fine. They were just about to eat.’ She flinched slightly as he said this, and Ed immediately regretted planting that little domestic tableau in her imagination. ‘How’s your foot?’

‘Hurts.’

She took a huge swig of her wine and he saw she’d downed a glass already. She got up, wincing, so that the peas fell onto the floor and poured herself another. Then, as if she’d just remembered something, she reached into the pocket of the robe, before holding up a little clear plastic bag.

‘Nicky’s stash,’ she said. ‘I decided this qualified as an appropriate moment for appropriating his drugs.’

She said it almost defiantly, waiting for him to contradict her. When he didn’t, she pulled out Nicky’s papers and dragged a tourist guide from the glass coffee-table onto her lap, where she proceeded to roll a haphazard joint. She lit it, and inhaled deeply. She tried to smother a cough, then inhaled again. Her towel turban had started to slide and, irritated, she tugged it off, so that it was just her wet hair around her shoulders. She inhaled again, closed her eyes, and held it out towards him.

‘Is that what I could smell when I came in?’

She opened one eye. ‘You think I’m a disgrace.’

‘No. I think one of us should be in a state to drive, just in case Tanzie wants picking up.’

Her eyes widened.

‘It’s fine,’ he said. ‘Really. You go ahead. I think … you need …’

‘A new life? To pull myself together? A good seeing-to?’ She laughed mirthlessly. ‘Oh, no. I forgot. I can’t even do that right.’

‘Jess …’

She raised a hand. ‘Sorry. Okay. Let’s eat.’

They ate at the little laminated table beside the kitchen area. The curries were serviceable, but Jess barely touched hers, preferring to drink. She pushed the chicken biryani to and fro on her plate, until it was clear that she wasn’t going to eat more than a few mouthfuls, and he offered to clear it away.

As he put the plates on the side and prepared to wash up, she faced him. ‘I’ve been a total idiot, haven’t I?’

Ed leant back against the kitchen units, a plate in his hand. ‘I don’t see how –’

‘I worked it all out in the bath. I’ve been blathering to the kids all these years about how if you look out for people and do the right thing it will all be okay. Don’t steal. Don’t lie. Do the right thing. Somehow the universe will see you right. Well, it’s all bullshit, isn’t it? Nobody else thinks that way.’

Her voice was slightly slurred, its edges frayed with pain.

‘It’s not –’

‘No? Two years I’ve been flat broke. Two years I’ve been protecting him, not adding to his stress, not bothering him about his own children. And all the while he’s been living like that, in his executive home, with his highlights and his designer jeans and his new girlfriend.’ She shook her head in wonder. ‘I didn’t suspect a thing. Not for one minute. And I worked it out, while I was in the bath … that whole “do as you would be done by” thing? Well, it only works if everyone else does it. And nobody does, any more. The world is basically full of people who couldn’t give a shit. They’ll tread all over you if it means they get what they want. Even if it’s their own kids they’re treading on.’

‘Jess …’

He walked around the kitchen units until he was inches from her. He couldn’t think what to say. He wanted to put his arms around her, but something about her held him back. She poured herself another glass of wine, and lifted it towards him.

‘I don’t care about that woman, you know. That’s not it. Me and Marty were over a long time ago. But all that crap about not being able to help his own kids? Refusing to even think about helping Tanze with school fees?’ She took a long gulp of her drink and blinked slowly. ‘Did you see that girl’s top? That designer top? You know how much they cost? Sixty-seven pounds. Sixty-seven pounds for a child’s sweatshirt. I saw the price tag when Druggie Aileen brought one round.’ She wiped angrily at her eyes. ‘You know what he sent Nicky for his birthday in February? A ten-pound voucher. A ten-pound voucher for the computer-games shop. You can’t even buy a computer game for ten pounds. Only second-hand. And they don’t always wipe the second-hand ones so someone else will have got all the points. And the stupid thing is we were all really pleased. We thought it meant that Marty was getting better. I told the kids that ten pounds, when you’re not working, is actually quite a lot of money.’
