I walked on. A stream of motor cars was flowing swiftly through the square, separating into two channels around the bronze horseman's plinth and meeting and mingling again in cacophonous disorder on the other side. The sun was being stealthily swallowed by a fat, barely moving cloud, putty-grey and burning silver all along its forward edge. A pigeon landed in front of me, descending in an awkward flurry on churning wings, like a rapid succession of violet-grey ink-blot tests. I turned again and struck away from the square, and walked through ever narrower, cobbled streets, until I came out at last unexpectedly into a wide avenue flanked on both sides with chestnut trees in flower. Here I could breathe more easily. As I passed under the first broad, high, cool canopy of leaves, it occurred to me to wonder when a tree would feel most like itself, when it would feel it had most fully achieved its true being. I mean, if it were sentient – and who is to know if we are the only conscious ones, or that our consciousness is the only kind there is? – at what stage of its yearly cycle would it say, now, now I am what I am, now at last I am in my total treeness. Would it be in spring's first greening, or the full-leafed glory of June, or autumn flame, or even the gnarled nakedness of winter? And to live that cycle of life within another cycle – the one from bud to bareness, the other, the longer one, from sapling to hollow stump – surely that would be confusing. Would the fall of its leaves feel like incipient death, each year? Would spring feel like rebirth? Thinking these thoughts, in that midday's green dusk, I heard, or felt, rather, a reverberant boom, as if in the distance a great sheet of pliant metal had been struck with a huge, soft hammer. Thunder? I did not think so. Some aeroplane noise? A cannon shot, perhaps, marking the midday hour? Whatever it was it disturbed me. I quickened my pace, veering off in the direction of the hotel.

Presently I realised that I had lost my way, and I had to stop at a street corner to consult the crumpled map the hotel clerk had given me. I was squinting up in search of a street name when I registered the girl, on the corner opposite, looking in my direction. She was tallish, fair, neither pretty nor plain; I would not have noticed her had she not seemed to be regarding me with a smile, knowing, not unfriendly, as if I were someone she had met long ago, in faintly discreditable circumstances. She stepped forward into the street, squeezing between two cars parked closely nose to tail. Was she coming to accost me? The prospect made my pulse quicken, and I did not know whether to wait for her or flee. Who were all these people, the flower seller, Carrot Head, now this girl, and what did they want with me? The lorry had already braked, its tyres locked and shrieking, when it struck her. I had the sense of her spinning on her toes, head thrown back and hair flying, fast and tensely graceful as a dancer. There was a cry, not hers. A burly, grey-haired man on the pavement behind her threw up one arm and said something loud and deprecating in a deep bass voice. Vehicles squawked and pulled aside to right and left as the lorry hurtled down the centre of the street for twenty yards and came at last to a slewed, smoking stop. The girl had fallen back and was draped against the side of one of the parked cars with her arms flung wide. There was blood in her hair, and a glistening, innocent-looking trickle of blood coming out of her left ear. The large man who had thrown up his arm was toiling toward her at a bow-legged run, but before he could reach her she slithered abruptly to the ground as if everything inside her had suddenly liquefied, and lay in a boneless heap. Now others were running forward, and people were scrambling out of their cars and craning to see what had happened. I turned about quickly and set off at a headlong lurch, not caring which direction I was going in, so long as it was away from there. People jostled me, pressing forward for a glimpse of the fallen girl, with vague, eager, self-forgetting frowns. I was in a sort of panic, gasping, the sweat running into my eyes, and there was a blazing pain deep in my groin. I did not know what I was fleeing from; not the girl's death, certainly, or not only that. A half-formed image came to my mind – from Bosch, was it, or Dante? – of an emaciated, gape-mouthed figure, stooped and naked, running with uplifted arms through a landscape of burning red earth, bearing another figure, its own double, lashed to it tightly back to back. At last I came to the quiet of a secluded small piazza, with cobbles and more strutting pigeons and a patch of dusty grass, all loured over by the baroque, blocky façade of a palace, the name of which I knew I should know but could not remember. Unable to go any further I flopped down on a bench of polished marble. There was no one else about. A noontide pall of lethargy had fallen on the city. That slow cloud now hid the sun, and the soft grey air and the silence calmed my seething nerves. The pain in my groin subsided.

Why such upset? This was not the first violent end I had witnessed. Was it that it was another of death's heartless demonstrations that even the young are not immune to its capricious singlings-out? No, that is too obscure. Perhaps it was simply because the girl had seemed to be looking at me, had seemed to know or recognise me, might even have been about to speak to me. But why should that make the encounter, if such it could be called, so unsettling? In certain circles, admittedly rarefied, mine is a well-known face. I am used to strangers recognising me. They will pause, the young in particular, and look at me, shyly, or with resentment, or more often just that slow, dull, witless stare, as if it is not the real me they are seeing but a representation of me, an animated model set up for their free and exclusive scrutiny. So why should the girl's attention have made me want to take to my heels? Oh, but I knew, I knew of course, why I was agitated: it was not the girl I was thinking of, it was Magda. When she was alive I could hardly be said to have given her a second thought, while now she was constantly on my mind, if only as a shadow, the solitary spectator sitting in the benches above the spotlit ring where the gaudy and increasingly chaotic performance of who and what I am pretending to be is carried on without interval. She lingers there, unwilling shade, wishing to be gone, perhaps, yet curious to see the not so grand finale, with its tumbling clowns and bowing acrobats and trained animals doing their last lap. Only in death has she begun to live fully, for me.

Strange, but try as I may I cannot remember exactly how or when we met. In my memory of it, that first, long-ago season in an unreally vivid New York is all haste and noise and sullen heat. Even in the streets I felt as if I were trapped inside a huge, smoky, deafening factory. Everything was always on the move, there was never a moment of cessation or stillness. Traffic thudded day and night along the streets above the corner basement room where I lodged; the papers on the scarred old table I used for a work desk shivered and shifted in the draught from the electric fan some acquaintance had given me, as it turned its fuzzy face and fencer's mask slowly from side to side in obdurate refusal of relief. All day a confusion of disembodied legs passed back and forth on the pavement outside the ground-level window above my table, as if there were a riot, or a disordered, shuffling marathon dance, continually going on out there. And then there was the talk, incessant, raucous, plosive with challenge or swollen with sudden declarations of sincerity and fellow-feeling. I would meet them at the end of their working day – work was one of the sacred words then, pronounced with breathy awe – the scrawny young men in open-necked shirts, with their flat haircuts and Zippo lighters, sweating earnestness, the serious-eyed girls in pumps and calf-length skirts clutching paperback copies of Capital to their chests like breastplates. The thin, sweetish beer, the charry cigarette smoke, the sudden squabbles that were as suddenly quelled, the shouts and thrusting forefingers, and that gesture of half-angry dismissal of a contrary opinion, so characteristic of the time and place, a free-wristed, sideways slap at the air and the face turning aside, with wrinkled nose and drooping lower lip: Ndah! – all this was intensely strange to me, and yet familiar, too, I could not think why, at first, until I realised that of course I had seen it all over and over again, for vears, in the cinema, every Saturday night, when I was young. America on the screen had been more intimately familiar to me than the streets of the city where I was born and where I lived. And so, in New York, the actual New York, that was how I chose to present myself, as a character out of the pictures, a fat cigarette lolling in my lips and a tumbler of bourbon at my elbow. I even used to dress the part, in brown fedora and tight, double-breasted suit and two-toned shoes. Oh, yes, it was quite a figure that I cut. The intellectual as tough guy, that was all the rage, in those days. All I lacked was a companion, some big babe, loose and hard-drinking, and as tough as I was supposed to be. People were baffled, therefore, especially the girls, when it turned out to be sweet, silent, undemonstrative Magdalena that I chose to be my moll, my mate. Even then, when she was still in her twenties, there was a massive, stony quality to her, something granitic and unrelievedly grey, that was curiously attractive, to me, at least. I quickly understood, when I first began to notice her, that she kept to the background not out of shyness or fear – although she was shy, she was fearful – but in order to be able to watch and listen to all that went on from the shelter of anonymity. She was unflagging in her obligingness, doing errands for the men and the bossier of the girls, fetching books for them, and packs of cigarettes, and sandwiches and paper cups of coffee; I can still see her, in her sandals and no-colour knitted dress, her hair in fat braids, coming down the basement steps in that odd, elephantine way that she had, turning sideways and lowering one broad foot on to each step and then bringing the second down to join it, her chin tucked into her fish-pale throat and her gaze fixed on whatever it was she was carrying. She was living on the Lower East Side – a placename that in those days still sounded as suggestively exotic to my ears as Samarkand or the Isles of the Blest – with a plumber, a militant Pole of simian aspect with a revolutionist's wire-brush moustache, who was said to beat her. She would not talk about him, even when she had left him and had come to live with me in my basement, bringing a bottle of bourbon as a moving-in present and one not very large suitcase containing everything she possessed. Late one night the Pole turned up in the street outside, drunk and in a tearful rage and calling out her name, and banged on the door and would have kicked in the window had it not been barred. I wanted to get up and chase him away – even with my bad leg I did not doubt I would be well able to see off the little ape – but Magda prevented me.
