The champagne and the floor show inflamed him slightly. In the old days, he would at this point have taken Julia home and made love to her roughly-she liked that, just occasionally. But now she no longer came to town, and he no longer went to nightclubs, not normally.

The girls had not been introduced. Tim started to talk to the nearest, a flat-chested redhead in a long dress of some pale color. She looked like a model, and said she was an actress. He expected that he would find her boring, and that she would reciprocate. That was when he got the first intimation that tonight would be special: she seemed to find him fascinating.

Their close conversation gradually isolated them from the rest of the party, until someone suggested another club. Tim immediately said he would go home. The redhead caught his arm and asked him not to; and Tim, who was being gallant to a beautiful woman for the first time in twenty years, instantly agreed to go along.

He wondered, as he got out of the bath, what they had talked about for so long. The work of a Junior Minister in the Department of Energy was hardly cocktail-party conversation: when it was not technical, it was highly confidential. Perhaps they had discussed politics. Had he told wry anecdotes about senior politicians, in the deadpan tone which was his only way of being humorous? He could not remember. All he could recall was the way she had sat, with every part of her body angled devotedly toward him: head, shoulders, knees, feet-a physical attitude that was at once intimate and teasing.

He wiped steam off the shaving mirror and rubbed his chin speculatively, sizing up the task. He had very dark hair, and his beard, if he were to grow it, would be thick. The rest of his face was, to say the least, ordinary. The chin was receding, the nose sharply pointed with twin white marks either side of the bridge where spectacles had rested for thirty-five years, the mouth not small but a little grim, the ears too large, the forehead intellectually high. No character could be read there. It was a face trained to conceal thoughts, instead of displaying emotion.

He switched on the shaver and grimaced to bring all of his left cheek into view. He was not even ugly. Some girls had a thing about ugly men, he had heard-he was in no position to verify such generalizations about women-but Tim Fitzpeterson did not even fit into that dubiously fortunate category.

But perhaps it was time to think again about the categories he fitted into. The second club they had visited had been the kind of place he would never knowingly have entered. He was no music lover, and if he had liked it his taste would not have included the blaring, insistent row which drowned conversation in The Black Hole. Nevertheless, he had danced to it-the jerky, exhibitionist dancing that seemed to be de rigueur there. He enjoyed it, and thought he acquitted himself well enough; there were no amused glances from the other patrons, as he feared there might be. Perhaps that was because many of them were his age.

The disc jockey, a bearded young man in a T-shirt improbably printed with the words HARVARD BUSINESS SCHOOL, capriciously played a slow ballad, sung by an American with a heavy cold. They were on the small dance floor at the time. The girl came close to him and wound her arms around him. Then he knew she meant it; and he had to decide whether he was equally serious. With her hot, lithe body clinging to him as closely as a wet towel, he made up his mind very quickly. He bent his head-she was slightly shorter than he-and murmured into her ear: "Come and have a drink at my flat."

He kissed her in the taxi-there was something he had not done for many years! The kiss was so luscious, like a kiss in a dream, that he touched her breasts, wonderfully small and hard under the loose gown; and after that they found it difficult to restrain themselves until they reached home.

The token drink was forgotten. We must have got into bed in less than a minute, Tim thought smugly. He finished shaving and looked around for cologne. There was an old bottle in the wall cabinet.

He went back to the bedroom. She was still asleep. He found his dressing gown and cigarettes and sat in the upright chair by the window. I was pretty terrific in bed, he thought. He knew he was kidding himself: she had been the activist, the creative one. On her initiative they had done things which Tim could not suggest to Julia after fifteen years in the same bed.

Yes, Julia. He gazed unseeing from the first-floor window, across the narrow street to the redbrick Victorian school, its meager playground painted with the fading yellow lines of a netball court. He still felt the same about Julia: if he had loved her before, he loved her now. This girl was different. But wasn't that what fools always told themselves before embarking on an affair?

Let's not be hasty, he told himself. For her this might be a one-night stand. He could not assume she would want to see him again. Yet he wanted to decide where his aims lay before asking her what the options were: government had taught him to brief himself before meetings.

He had a formula for the approach to complex issues. First, what have I got to lose?

Julia, again: plump, intelligent, contented, her horizons contracting inexorably with every year of motherhood. There had been a time when he lived for her: he bought the clothes she liked, he read novels because she was interested in novels, and his political successes pleased him all the more because they pleased her. But the center of gravity of his life had shifted. Now Julia held sway only over trivia. She wanted to live in Hampshire, and it did not matter to him, so they lived there. She wanted him to wear check jackets, but Westminster chic demanded sober suits, so he wore dark, faintly patterned grays and navy blues.

When he analyzed his feelings, he found there was not a lot to tie him to Julia. A little sentiment, perhaps-a nostalgic picture of her, with her hair in a ponytail, doing the jive in a tapered skirt. Was that love or something? He doubted it.

The girls? That was something else. Katie, Penny and Adrienne: only Katie was old enough to understand love and marriage. They did not see much of him, but he took the view that a little father-love goes a long way, and is a great deal better than no father at all. There was no room for debate there: his opinion was fixed.

And there was his career. A divorce might not harm a Junior Minister, but it could ruin a man higher up. There had never been a divorced Prime Minister. Tim Fitzpeterson wanted that job.

So there was a lot to lose-in fact, all he held dear. He turned his gaze from the window to the bed. The girl had rolled onto her side, facing away. She was right to have her hair short-it emphasized the slender neck and pretty shoulders. Her back tapered sharply to a small waist, then disappeared beneath a crumpled sheet. Her skin was faintly tanned.

There was so much to gain. "Joy" was a word Tim had little use for, but it entered his thoughts now. If he had known joy before, he could not remember when. Satisfaction, yes: in the writing of a sound, comprehensive report; in the winning of one of those countless small battles in committees and in the House of Commons; in a book that was correct or a wine that was right. But the savagely chemical pleasure he had with this girl was new.

There: those were the pros and cons. The formula said, now add them up and see which is greater. But this time the formula would not work. Tim had acquaintances who said it never did. Perhaps they were right. It might be a mistake to think that reasons could be counted like pound notes: he was reminded, curiously, of a phrase from a college philosophy lecture, "the bewitchment of our intelligence by means of language." Which is longer-an airplane or a one-act play? Which do I prefer-satisfaction or joy? His thinking was getting woolly. He made a disgusted noise, then looked quickly at the bed to see whether he had disturbed her. She slept on. Good.
