“I’d already imagined how she was going to react to my declaration of undying love. A hesitant admission that she felt the same way. Then a passionate surrender. She’d let me kiss her. Maybe even let me take her upstairs and make love to her. Or arrange to meet me next day at some classy hotel, where we’d spend the whole of the afternoon and evening in bed. Later, we’d start planning our future together. Discuss where we were going to run away to. All self-deluding nonsense, of course. All so much folly and arrogance. But I was so taken in by the fantasy I’d created that it’s actually what I expected to happen.

“Needless to say, it didn’t. The first thing she said when I’d finished was, ‘Oh dear.’ She seemed more embarrassed than angry. Almost sorry for me. She tried to let me down lightly. She took me back into the lounge and gently explained the impossibility of what I’d suggested. She was a happily married middle-aged woman with a daughter my own age. There could be no question of her betraying her husband. With me or anyone else. Strangely enough, she didn’t seem particularly shocked. Perhaps other men had poured out their hearts to her in similar circumstances. Perhaps she was used to being the object of hopeless adoration. ‘This is just a phase you’re going through,’ she said. ‘A phase you’ll soon grow out of.’ She spoke of it so lightly, so dismissively. As if I was some silly little boy with a crush on her. I could have hated her if I hadn’t loved her. And in a sense I suppose that’s when I started to. Hate as well as love, I mean.

“But love’s the wrong word anyway, isn’t it? It was an obsession amounting to mania. I loaded everything of meaning and significance in my life onto her. I made winning her a test of the very purpose of my existence. A test I was bound to fail. Because she wasn’t interested. Not a bit. She wasn’t even worried by me. Not then, anyway, though later… She didn’t take me seriously, you see. That was the worst of it. I could have her pity. Even her scorn, if I persisted. But never what I wanted. Never, come to that, her respect, now I’d shown my hand.

“She very politely threw me out. Reckoned it would be best if I didn’t wait for Sarah. But she promised not to tell her anything. ‘Let’s forget this ever happened,’ she said. ‘Let’s write it off as an unfortunate misunderstanding.’ I suppose that’s what it was in a way. A misunderstanding. She just didn’t understand that I really meant it. And I didn’t understand how preposterous what I meant really was.

“But as for writing it off, that didn’t seem possible. I called her several times over the next few days. Put the phone down if somebody else answered. Spoke if it was her. I begged her to reconsider. Pleaded with her to give me a chance. Just one meeting. Just a few minutes of her time. Eventually, she agreed. We met in a café in Covent Garden. Her mood had changed by then. If I persisted, she said, she’d inform the college authorities. So far, nobody else knew. But if I didn’t stop now, everybody would know. Sarah. My parents. My fellow students. My director of studies. My tutor. In my own interest, I had to give up. Immediately. As she very much hoped I would.

“I hadn’t promised anything when she left. But I did try. The disgrace and the mockery a formal complaint by her could bring down on me was a sobering thought. It made me see reason. For a while, anyway. I wrote her an apologetic letter, saying she wouldn’t hear from me again. And I meant it. I really did. I went back to Cambridge after Easter determined to knuckle down to my studies and forget this ludicrous pursuit of an older woman.

“For a while, I almost thought it would work. But once my exams were over, I found myself with a lot of time on my hands. A bloke I shared a landing with, Peter Rossington, said he was looking for a partner for an inter-rail trip round Europe that summer. You know, the cheap rail pass tour most students do at least once. Well, it was either that or Surbiton. Not much of a contest. I said I’d go with him and we agreed to set off early in July. Until then, I had nothing to do but laze around Cambridge and think. About Louise. About how I might still make her change her mind. About how I might yet persuade her to give herself to me, even against her better judgement. I stayed on till the bitter end of full term and was still there when the third year students came back to graduate. Including Sarah. Which meant Louise was bound to come to Cambridge as well. I wheedled out of Sarah which hotel her parents would be staying in. The Garden House. A big modern place on the Cam, behind Peterhouse. The graduation ceremony was on the last Friday in June. They were to arrive on the Thursday and leave with Sarah on the Saturday.

“I should have left on the Wednesday, of course. Or sooner. But I didn’t. I hung around, hoping for a glimpse of her. Maybe even the chance of a talk with her. Early on Friday morning, I started walking along the riverside path on the opposite side from the Garden House. Down past the hotel and back. Again and again. Hoping she might see me from her room, even though I didn’t know if they had one facing the river. Well, she must have noticed me and walked round from the hotel to confront me, because suddenly she appeared on the path ahead, approaching from the Mill Lane end. And she was angry. ‘Are you mad?’ she demanded. ‘You agreed to leave me alone. What do you mean by patrolling up and down like this?’ I pretended it was all a big mistake. I just happened to be taking a stroll there, with no idea she was staying at the hotel. It was obvious she didn’t believe me, but she couldn’t prove me a liar either. In the end, she just walked away. I ran after her, begging her to stop and talk. But she wouldn’t. I followed her all the way down Granta Place towards the hotel. Eventually, just inside the entrance, she stopped and rounded on me. ‘My husband’s waiting to have breakfast with me in the restaurant,’ she said. ‘Do you want to join us, Paul? Do you want me to tell him what’s going on? There’ll be no going back if I do.’ Well, I wasn’t ready to confront Sir Keith. Not then. Not just like that. Her bluntness shocked me. I mumbled some kind of apology and beat a retreat.

“But it could never be a permanent retreat. I hung about the streets, watching the procession to the Senate House. Then I slunk round to the Backs and spied on the lunch party at King’s for graduates and parents. I caught a glimpse of Louise, looking radiantly lovely. Sir Keith was with her, of course. It was the first time I’d seen him. Naturally, he looked completely unworthy of her to me. I crept away and left them to it. I was utterly miserable by then. Depressed and disgusted with myself. Yet I was still so much in love with her I simply couldn’t put her out of my mind.

“They left next morning. I spent the weekend drinking. And formulating a plan. I was due to meet Peter in London on Wednesday. That gave me two days when I might be able to get Louise on her own. I didn’t know whether she’d be in Sapperton or London, so I decided to hedge my bets by going to Sapperton first, on Monday. I drove over there that morning. Arrived about eleven o’clock. Parked near the church. Spied out the land. Tried to think exactly how to approach her.

“I was sitting in my car at the end of the lane leading to The Old Parsonage when Sarah came past, returning from a stroll, I suppose. I didn’t see her coming and she spotted me straightaway. I trotted out some story about visiting an aunt in Cirencester and diverting to Sapperton to see if Sarah was free for lunch. Well, she seemed to be taken in by it. Nobody else was at home, apparently. She suggested we drive to a nearby pub. And I had to go along with it now I’d started, so off we went. To the Daneway Inn, down in the valley below Sapperton. It wasn’t exactly a relaxing occasion. I think Sarah was puzzled. Worried, perhaps, that I might want to start things up again between us. Maybe that made her nervous. And talkative as a result. Whatever the reason, she told me more about her family than she probably realized.
