Ten minutes later I was trudging along the road with my thumb stuck out when I heard her pull up behind me. I knew it would be she. I stopped, turned. She remained in the car, her wrists folded before her on the steering-wheel. There was a brief, wordless tussle to see which one of us would make the first move. We compromised. I walked back to the car and she got out to meet me. I thought it was you, she said. We smiled, and were silent. She wore a cream suit and a white blouse. There was blood on her shoes. Her hair was yellower than I remembered, I wondered if she was dyeing it now. I told her she looked marvellous. I meant it, but the words sounded hollow, and I blushed. Anna, I said. I remembered, with a soft shock, how one day long ago I stole the envelope of one of her letters to Daphne, and took it into the lavatory and prised open the flap, my heart pounding, so that I might lick the gum where she had licked. The thought came to me: I loved her! and I gave a sort of wild, astonished laugh. She took off her sunglasses and looked at me quizzically. My hands were trembling. Come and see father, she said, he needs cheering up.

She drove very fast, working the controls probingly, as if she were trying to locate a pattern, a secret formula, hidden in this mesh of small, deft actions. I was impressed, even a little cowed. She was full of the impatient assurance of the rich. We did not speak. In a moment we were at the house, and pulled up in a spray of gravel. She opened her door, then paused and looked at me for a moment in silence and shook her head. Freddie Montgomery, she said. Well!

As we went up the steps to the front door she linked her arm lightly in mine. I was surprised. When I knew her, all those years ago, she was not one for easy intimacies – intimacies, yes, but not easy ones. She laughed and said, God, I'm a little drunk, I think. She had been to the hospital in the city – Behrens had suffered some sort of mild attack. The hospital was in an uproar. A bomb had gone off in a car in a crowded shopping street, quite a small device, apparently, but remarkably effective. She had wandered unchallenged into the casualty ward. There were bodies lying everywhere. She walked among the dead and dying, feeling like a survivor herself. Good God, Anna, I said. She gave a tense little laugh. What an experience, she said – luckily Flynn keeps a flask of something in the glove compartment. She had taken a few good swigs, and was beginning to regret it now.

We went into the house. The uniformed doorman was nowhere to be seen. I told Anna how he had gone off and left me to wander at will about the place. She shrugged. She supposed everyone had been downstairs watching the news of the bombing on television. All the same, I said, anyone could have got in. Why, she asked, do you think someone might come and plant a bomb here? And she looked at me with a peculiar, bitter smile.

She led the way into the gold salon. The french window was still open. There was no sign of the maid. A sort of shyness made me keep my eyes averted from the other end of the room, where the picture leaned out a little from the wall, as if listening intently. I sat down gingerly on one of the Louis Quinze chairs while Anna opened the carved and curlicued sideboard and poured out two whopping measures of gin. There was no ice, and the tonic was flat, but I didn't care, I needed a drink. I was still breathless with the notion of having been in love with her. I felt excited and bemused, and ridiculously pleased, like a child who has been given something precious to play with. I said it to myself again – I loved her! – trying it out for the sound of it. The thought, lofty, grand, and slightly mad, fitted well with the surroundings. She was pacing between me and the window, clutching her glass tightly in both hands. The gauze curtain bellied lazily at the edge of my vision. Something in the air itself seemed to be shaking. Suddenly the telephone on the low table beside me sprang to life with a crashing noise. Anna snatched it up and cried yes, yes, what? She laughed. It's some taximan, she said to me, looking for his fare. I took the phone and spoke harshly to the fellow. She watched me intently, with a kind of avid amusement. When I put down the receiver she said gaily, Oh, Freddie, you've got so pompous! I frowned. I was not sure how to respond. Her laughter, her glazed stare, were tinged with hysteria. But then, I too was less than calm. Look at that, she said. She was peering in annoyance at her bloodstained shoes. She clicked her tongue, and putting down her glass she quickly left the room. I waited. All this had happened before. I went and stood in the open window, a hand in my pocket, swigging my gin. Pompous, indeed – what did she mean? The sun was almost down, the light was gathering in bundles above the river. I stepped out on to the terrace. A balm of soft air breathed on my face. I thought how strange it was to be here like this, glass in hand, in the silence and calm of a summer evening, while there was so much darkness in my heart. I turned and looked up at the house. It seemed to be flying swiftly against the sky. I wanted my share of this richness, this gilded ease. From the depths of the room a pair of eyes looked out, dark, calm, unseeing.

Flynn, the crop-headed chauffeur, approached me from the side of the house with an air of tight-lipped politeness which was somehow menacing, rolling on the balls of his disproportionately dainty feet. He sported a bandit's drooping blue-black moustache, trimmed close and squared off at the ends, so that it looked as if it had been painted on to his large, pasty face. I do not like moustaches, have I mentioned that? There is something lewd about them which repels me. I have no doubt the prison shrink could explain what such an aversion signifies – and I've no doubt, too, that in my case he would be wrong. Flynn's was a particularly offensive specimen. The sight of it gave me heart suddenly, cheered me up, I don't know why. I followed him eagerly into the house. The dining-room was a great dim cavern full of the glint and gleam of precious things. Behrens came in leaning on Anna's arm, a tall, delicate figure in rich tweeds and a bow-tie. He moved slowly, measuring his steps. His head, trembling a little, was smooth and steeply domed, like a marvellous, desiccated egg. It must have been twenty years since I had seen him last. I confess I was greatly taken with him now. He had the fine high patina of something lovingly crafted, like one of those exquisite and temptingly pocket-sized jade figurines which I had been eyeing only a moment ago on the mantelpiece. He took my hand and squeezed it slowly in his strangler's grip, looking deep into my eyes as if he were trying to catch a glimpse of someone else in there. Frederick, he said, in his breathy voice. So like your mother.

We dined at a rickety table in the bay of a tall window overlooking the garden. The cutlery was cheap, the plates mismatched. It was something I remembered about Whitewater, the makeshift way that life was lived in odd corners, at the edge of things. The house was not meant for people, all that magnificence would not tolerate their shoddy doings in its midst. I watched Behrens cutting up a piece of bleeding meat. Those enormous hands fascinated me. I was always convinced that at some time in the past he had killed someone. I tried to imagine him young, in flannels and a blazer, carrying a tennis racquet – Oh look, here's Binkie! – but it was impossible. He talked about the bombing. Five dead – or was it six by now? – from a mere two pounds of explosive! He sighed and shook his head. He seemed more impressed than shocked. Anna hardly spoke. She was pale, and looked tired and distracted. I noticed for the first time how she had aged. The woman I knew fifteen years ago was still there, but fixed inside a coarser outline, like one of Klimt's gem-encrusted lovers. I looked out into the luminous grey twilight, aghast and in an obscure way proud at the thought of what I had lost, of what might have been. Piled clouds, a last, bright strip of sky. A blackbird whistled suddenly. Someday I would lose all this too, I would die, and it would all be gone, this moment at this window, in summer, on the tender brink of night. It was amazing, and yet it was true, it would happen. Anna struck a match and lighted a candle on the table between us, and for a moment there was a sense of hovering, of swaying, in the soft, dark air.
