- No, but anything you would have said.

She had told them she had a doctor's appointment and needed extra time for lunch. She told him that. As she entered the hotel elevator he could not help but notice her fine hips. Then, incredibly, they were in the room. His heart was uncontrollable and everything was prepared for them, the sleek furnishings, the chairs, the thick fresh towels in the bath. There had been four murders in Brooklyn the night before. The brokers were going wild on Wall Street. On Fourteenth, men stood in the cold beside tables of watches and socks. The madman on Fifty-seventh was singing arias at the top of his voice, buildings were being torn down, new towers rising. She rose to draw the drapes and for a moment stood in the s.p.a.ce between them, in the light and looking down. The splendor and newness of her! He had known nothing like it.

Her apartment was borrowed, from someone on a.s.signment. Even at that, it was spa.r.s.ely furnished. He wanted to give her something every time he saw her, a gift, something unexpected, a chrome and leather chair that he showed her in the window before he ordered it delivered, a ring, a rosewood box, but he was careful to keep nothing that came from her- note, e-mail, photograph-that might betray him. There was one exception, a picture he had taken as she half sat up in bed, from over her bare shoulder, b.r.e.a.s.t.s, smooth stomach, thighs, you would not know who it was. He kept it at work between the pages of a book. He liked to turn to it and remember.

In those days of desire so deep that it left him empty-legged, he did not behave unnaturally at home-if anything he was more loving and devoted although Lily, especially, was beyond increased devotion. He came home filled with forbidden happiness, forbidden but unrivalled, and embraced his wife and played with or read to his children. The prohibited feeds the appet.i.te for all the rest. He went from one to the other with a heart that was pure. On Park Avenue he stood on the island in the middle, waiting to cross. The traffic lights were turning red as far as he could see. The distant buildings stood majestic in the monied haze. Beside him were people in coats and hats, with packages, briefcases, none of them as fortunate as he. The city was a paradise. The glory of it was that it sheltered his singular life.

- Am I your mistress? she asked one day.

- Mistress? No, he thought, that was something older, even old-fashioned. He knew of no word to truly describe her other than probable downfall or perhaps fate.

- What's your wife like? she said.

- My wife?

- You'd rather not talk about her.

- No, you'd like her.

- That would be just my luck.

- She doesn't have quite your ideas of how to live.

- I don't know how to live.

- Yes, you do.

- I don't think so.

- You have something not a lot of people have.

- What's that?

- Real nerve.

When he came home that evening, his wife said, - Brian, there's something I want to talk to you about, something I have to ask you.

He felt his heart skip. His children were running toward him.

- Daddy!

- Daddy and I have to talk for a minute, Sally told them.

She led him into the living room.

- What's up? he said as calmly as he could.

Grace and Harry, it turned out, wanted to come with their children and share the gardener's cottage during the two weeks in August that Lily would be off at sleepaway camp and some arrangement could be made for Ian so that Sally and Brian could have some time to themselves. Now that would be impossible.

She went on talking, but Brian barely listened. He was still hearing her first words that had been so frightening. He was rehearsing replies to a far more serious question. He would tell her the truth, could he do that? The truth was essential, yet it was the thing least wanted.

- We should do this over a drink, he would say. We should do it when we're calmer.

- I'm not going to be calmer.

He had to somehow put it off until she was the way she often was, clever and understanding. He would say something about perspective.

- Just speak in plain English.

- You can't say it in plain English.

- Try, she said.

- You know these things happen. You're a smart woman. You know something about the world.

- Yes, tell me about it.

Her mouth was turned down, a corner of it trembling.

- There's been someone, but it's not important. Can't you see that it's not important?

- Get out of here, she said, and don't come back. Don't try to see the children, I won't let you. I'm going to change the locks.

- Sally, you can't do that. I could never live like that. Don't be melodramatic, please. That's not our kind of life. The words were beginning to jam up in his mouth. This is nothing unsolvable. You know very well that Pascale was your father's mistress, I won't guess for how long.

- They got married.

- That isn't the point.

He was beginning to stutter.

- What is the point?

- The point is there's a superior way of living we should be intelligent enough to understand.

- Which means you having some other woman?

- You're making this caustic. Don't, please. It's beneath us just to play roles. We're above that. You know that.

- All I know is that you're a cheat.

- I'm not a cheat.

- Daddy's going to kill you.

He couldn't find the words. Whatever he thought of was torn apart by her single-mindedness. But it would never come to this.

On the other hand, Pamela had a life of her own; that was the only flaw. She went out at night, there were parties. Some Tunisians from the delegation were very nice.

- Is that right? he said.

She'd gone to a party at the Four Seasons, she told him, and walked to work the next morning with a thousand dollars in her shoe, although she didn't say that. One of the Tunisians was particularly nice.

- They like to have fun, she said.

- You're turning into a playgirl, Brian said, a little sourly. How do I know you're not playing around with this guy?

- You'd know it.

- Maybe I would. Would you tell me? The truth? What's his name?

- Tahar.

- I wish you wouldn't.

- I'm not, she said.

In June, Sally and the children went to the country for the summer. For most of the week, Brian was in the city by himself.

- How was I lucky enough to meet you? he said.

They were having dinner amid the liveliness of the crowd, the intimacy within it, the voices all around. He had seen most of them. She was by far the prize of the room.

- We're going to be friends for a long time, she promised.

Summer mornings with their first, soft light. Amorous mornings, the red numbers flicking silently on the clock, the first sunlight in the trees. Her stunning naked back. The most sacred hours, he realized, of his life.

Dressing one morning, she asked, - Whose are these?

In a folded packet on the night table had been a pair of shining earrings.

- Are they your wife's?

She was trying one on, fastening it to her ear. She turned her head one way and the other, looking at herself in the mirror.

- What are they, silver?

- They're platinum. Better than silver.

- They're your wife's.

- They were being repaired. I had to pick them up.

It was hard not to admire her, her bare neck, her aplomb.

- Can I borrow them? she asked.

- I can't. She knows I was supposed to pick them up.

- Just say they weren't ready.

- Darling . . .

- I'll give them back. Is that what you're afraid of? I'd just like to wear them once, something that's hers but at the moment mine.

- That's very Bette Davis.

- Who?

- Just be careful and don't lose them, he managed to say.

That was a Tuesday. Two nights later a terrible event occurred. It was at a reception given by a group dedicated to the Impressionists; Pascale was a supporter but was away that evening and couldn't attend. Sally had insisted that Brian go, and in the crowd coming up the stairway he had seen, with a stab of jealousy, more fierce because it was a complete surprise, Pamela. He began to push his way forward to see who she might be with.

- Hey, where are you going in such a hurry?

It was Del, his brother-in-law.

- Where have you been hiding?

- Hiding?

- We haven't seen you for weeks.

Brian liked him, but not at this moment.

- Why don't you come to dinner with us tonight, afterward?

- I can't, Brian said unthinkingly.

- Come on, we're going to Elio's, Del insisted. Look at all these women. Where do they come from? They weren't around when I was single.

Brian hardly heard him. Past his brother-in-law, near the windows not fifteen feet away, he could see Pamela talking to Michael Brule, not just exchanging a greeting but in some sort of conversation. She was wearing a pale blue dress, one he liked, cut low in back. Her dark hair was tied and he could see quite clearly, she was wearing the earrings. They were unmistakable. He moved a bit so as not to be observed, his heart beating furiously. Finally Brule was gone.

- Darling, you must be crazy, he said in a furious, low voice when he reached her.

- h.e.l.lo, she said cheerfully.

There was always such life in that voice.

- What are you doing? he insisted.

- What do you mean?

- The earrings!

- I'm wearing them, she said.

- You can't wear them. That was my father-in-law. He bought them! He gave them to Sally! Why did you wear them here?
