‘I’m so sorry, Ellie.’

‘Thank you,’ I said politely, and folded my hands in my lap. I looked at the fingers laced together and thought I would be keeping my wedding ring off my finger after all.

‘You were wonderful, the way you trusted him.’

‘I did, didn’t I?’

‘At least you know now.’

‘That’s true.’

‘Can I get you a cup of coffee?’

‘No, thank you.’ He looked so wretched that I forced myself to make an effort. ‘This must be really horrible for you, Fergus. But I’m glad you told me. It would have been terrible not to. I’m grateful.’

‘He was a fool. An idiot. But he loved you, Ellie, I know he did. You mustn’t forget that.’

‘It’s nice of you to say so. If you don’t mind, I’d quite like to be alone now, Fergus.’

He stood up, and I remained where I was, so that he had to bend down awkwardly to kiss me on both cheeks.

‘I’ll phone later,’ he said.

After he had gone, I continued sitting on the sofa with my hands clasped together. I don’t know how long I stayed like that, or what I thought about. Perhaps those words: ‘I’ll show you more new tricks.’ What kind of love note was that, with its tacky and teasing suggestiveness, as if Greg was a circus pony and she the ring-master with the whip and black boots? I squeezed my eyes shut, trying to stop the images that were flooding through me. Perhaps I thought how extraordinarily, stunningly and flawlessly good he had been at keeping it secret from me, like a professional spy. Perhaps I thought it didn’t make sense, or that it made perfect sense, at last.

Finally I stood up and pulled out the chart again, staring at the gap in the schedule that I could now fill in: Greg was with Milena. I unrolled her much less filled-in chart as well. Nothing for 12 September there either. So. She had wanted him to stay the night next time. Had he? I couldn’t see when he would have done, but neither could I see why it should matter any more. I had the evidence I’d been searching for and dreading. As clearly as if she was in the room, I heard Mary’s voice: ‘Now you can get on with the rest of your life.’

Right. I stood up abruptly and went upstairs into our bedroom; into my bedroom. I opened the wardrobe and pulled out Greg’s handful of smart shirts, most of which I’d given him over the years, and his jackets. They would do for a start. I had been going to share them out among friends but now that didn’t feel right. On my way downstairs, I grabbed his old towelling robe from the back of the door. I wouldn’t be snuggling up in it on a cold evening any more.

In the garden, I bundled them into a pile and put a match to them. You’d have thought clothes would burn easily, but not those. It was nearly dark, and it was drizzling, which didn’t help matters – and the neighbour on the right, who had once complained to us about our loud music, was looking at me inquisitively while he put vegetable peelings on to his compost. I went into the shed, took paraffin from the top shelf and splashed a bit over the damp pile. I didn’t even need to add another match; an ember must still have been glowing in the folds of a jacket, because there was a bang, a ‘Whoa!’ from over the fence, and a violent orange flame roared several feet into the air. I could smell burning and realized my hair was singed. Who cared? Who cared what the neighbour thought, or his wife, who had now been summoned to watch the scene that was taking place? Who cared that acrid clouds of smoke were now rising from my fire, and petals of ash were floating in the air? Not me. I threw on his lovely leather brogues. They made a terrible smell. As I watched them blacken, I had a sudden picture of Greg buffing them with a soft cloth, that look of concentration on his lovely face, and wanted to rush forward and rescue them, but it was too late for that.

The elation had drained away and I felt empty, bleak, grim, defeated. Tired of the whole sorry business, of being angry, being ashamed, being sad, being lonely. Being me.

Perhaps that was why I returned to Frances’s the following morning. Because there, for a time, I wouldn’t have to be me. I could be Gwen: practical, calm and in control, helping other people sort out the mess of their lives. The previous night I had gone to bed early, without eating anything and hugging a hot-water bottle because although it was not a particularly cold evening I felt chilly and shivery. I lay there, wide-eyed, in the darkness. I wanted to cry, in the same way that sometimes, when I feel horribly nauseous, I want to be sick, but the tears didn’t come, wouldn’t. Several times, I had heard the phone ring and voices leave messages: Fergus, Gwen, Joe, Gwen again. They must have heard on the grapevine. Soon everyone would know.

It took me a long time to choose what to wear. I tried on skirts, tops, different shoes. I stood in front of the mirror, examined myself critically and didn’t like what I saw. I was pale; there were tired smudges under my eyes; my hair hadn’t been cut for months and was long and wild. In the end I put on a dress that looked a bit like a pleated chocolate-coloured sack, ribbed tights and my only pair of boots, although one of the heels was a bit loose. I put an amber pendant round my neck, because Greg hadn’t given it to me, and tied my hair back into a messy bun. I put on muted eye-shadow, eye-liner, mascara, lip-gloss. Finally, when it was after eleven o’clock and a pale sun had come out from behind the clouds, I looked enough like somebody else to venture out of the house.

For a moment I thought Frances was going to hug me, but she contented herself with a hand on my shoulder and a warm, relieved smile.

‘Hello,’ I said. ‘Sorry about yesterday.’

‘I’m just pleased you’re here now. Come downstairs. Johnny’s made us a pot of coffee.’

‘Johnny?’

‘Yes. Listen, I need you to do me a favour. Anyway, it’ll be more interesting for you than just trawling through the papers.’

‘What is it?’ I asked. Trawling through the papers was exactly what I wanted to do: I hadn’t finished with Milena Livingstone yet. Her chart was incomplete. My need to know about her had not been extinguished by that single coarse message scrawled so carelessly on the back of one of her menus. Now I wanted to know why – why had Greg fallen for her? What did she have that I didn’t?

‘I’ve got to dash out.’ She waved her hand vaguely in the air. ‘Crisis. But I’d promised Johnny I’d go to sample some of his suggested dishes, make the final choices. You can go instead of me.’

‘Wouldn’t it be better if Beth did it?’

Frances frowned. ‘Beth isn’t here yet. Besides, she doesn’t deserve it.’

‘I don’t know anything about food.’

‘You eat, don’t you?’

‘Kind of.’

‘Then it’ll be a treat for you. Are you hungry?’

I tried to remember when I’d last eaten a proper meal.

‘Good. That’s settled, then,’ said Frances, as if she had read my mind.

Johnny arrived with the coffee. He kissed me on one cheek, then the other, and said I was looking lovely. I stammered something and caught Frances’s amusement and something else. Tenderness?

Johnny’s restaurant was in Soho, down a little side alley. I knew it must be exclusive because it was almost impossible to spot from the street. The dining room was small, maybe ten tables, only one of which was unoccupied as we came in. With its low ceilings and deep-red wallpaper, it had the air of being someone’s private house rather than a public place. There was the hum of conversation, the chink of cutlery on china; waiters padded through, hovering deferentially over diners, pouring the last of the wine from bottles into glasses.

‘Nice,’ I commented.

‘They’re all here on expense accounts,’ Johnny said dismissively. ‘They don’t even taste what they’re eating. Why do we bother?’

‘Shall I sit here?’ I gestured to the single empty table.

He shook his head and whisked me through the door at the back and suddenly I was in an entirely different world, a brightly lit space of gleaming stainless-steel surfaces and scrubbed hobs. It was like a laboratory where men and women in white aprons bent over their work, occasionally calling instructions or pulling open vast drawers to reveal ingredients. I stared around me in fascination. Johnny pulled out a stool and sat me down at the end of a counter. ‘I’ll give you some things to try.’
