When the boy demolished Pettifer in the first game of backgammon we all cried beginner’s luck, but then they played twice more—each bout a little faster than the one before—and it soon became clear that young Fullerton possessed a startling tactical acuity. He came away with a haul of Pettifer’s belongings: a çay glass, a wind-up turtle made from camphor-wood, and a woven leather belt; and, because I had backed Tif to sweep the best of five, I was forced to surrender my last remaining pack of cinnamon gum. We assumed that Quickman, a shrewder, more experienced and aggressive player, would prove too wily an opponent for the boy, but it did not transpire that way. Fullerton outmanoeuvred him to the tune of seven points per game. In truth, it was barely a contest. By the time the boy was done, he had won a fountain pen, a Roman coin, and a silver lighter that once belonged to Quickman’s father, inscribed with two faded initials. (Tif won back a pair of loafers he had previously lost to Q, and I earned a scoopful of French coffee beans from Mac, though it seemed unfair to claim my winnings in her absence.)

‘We’ve been hustled,’ Quickman said, staring at the chequers that were left on the board. ‘That last bump-and-run was tournament stuff. What are you, regional champ? National?’

The boy beamed back at him. ‘I swear, I’ve hardly played before.’

‘You don’t fool me.’

‘I’m just lucky, that’s all. The dice fell kindly.’

‘Rubbish. I’ve never seen so much blockading. That was all strategy.’

‘It’s a blocking game all right,’ Pettifer added, ‘but it’s deadly effective.’

The boy gave nothing away. ‘If you say so.’

‘I’d better sharpen up my end-game before we play again,’ Quickman said.

‘I’m not sure that’ll help you much.’

I could not tell if the boy was being earnest or smug. He got up, took his cagoule from the chair-back, and walked across the studio, pausing before my wall of samples. The room was so bright with the overhead fluorescents that there was nothing but an arrangement of white patches for him to see, a grid of small canvas squares that I had pasted to the wall, in a pattern only I could interpret. There were at least a hundred of them, each square containing a smear of white paint, hardly discernible from the canvas itself. Fullerton took another forward step, trying to read my pencilled notes in the margins. ‘What is it you’re working on here, Knell?’ he said quite innocently. ‘I’m going to take a wild guess and say it’s something white.’

Pettifer tutted. ‘You’re overstepping.’

‘It’s all right,’ I said.

‘No, come on—he needs to be told.’

Quickman called to the boy in a chiding tone: ‘We don’t intrude on other people’s work round here.’

Fullerton held up his hands in surrender. ‘Jesus. Sorry. I take it back.’

‘They’re studies for a mural,’ I told him. ‘That’s as much as I care to explain right now.’

‘Anything else would be an imposition,’ Quickman said.

The boy was still facing the wall. ‘But don’t you ever want to run ideas by each other? Just to see the response?’

I was getting used to holding conversations with his back. ‘Sometimes,’ I said. ‘But then I wouldn’t really be painting for myself. And that’s the only way to paint.’

Quickman was now gathering the backgammon chequers into one hand, stamping down at every piece. It was evident that he was still stinging from defeat, because he said sharply to the boy, ‘This isn’t a conservatoire. If you’ve come here for other people’s input, you might want to try a different crowd.’

Fullerton turned and pushed up his sleeves. ‘It’s OK. I’m not the sharing type.’ There was still a pale disc of skin on his left wrist where a watch used to be. ‘I’ve got something I need to finish, yes, but I won’t bore you with the details.’

‘I saw a guitar in your studio,’ I said. ‘It’s been a while since we had a musician here.’

‘Oh, I wouldn’t call myself a musician.’

‘What are you then?’

He backed away from my samples now, eyes slatted. ‘Jacqueline du Pré—she’s a proper musician; Glenn Gould, Miles Davis. I can bash out a folk song when I’m in the mood. But I haven’t felt much like it recently.’

Pettifer stood up. ‘All sounds rather simple when you put it like that.’

‘I’m sure it’s more complicated than he’s making out,’ Quickman said, ‘or he wouldn’t be here, would he?’

‘The boy gave a wan little smile. ‘Stop me if I’m sharing too much.’

‘Well, I always wished I could play an instrument,’ I said. ‘Somehow I just can’t get the knack for it. A bit like backgammon.’ As a child, I had often sneaked my mother’s squeezebox from its case and tried to draw a tune from it, but all it ever gave me were wheezes of complaint.

‘I taught myself from a picture book,’ the boy replied. ‘It’s not that hard.’

Quickman folded up the game board and shoved it under his armpit. ‘The last musician we had played the bloody flute all night. It was like having swallows in the loft. I was this close to throttling him.’

‘Then I should probably keep the noise down.’

‘If you know what’s good for you.’

The boy did not answer. He stooped to examine the samples again. ‘There’s something really peaceful about this wall of yours, Knell. Not that you want my opinion.’

‘It’s a far cry from anything right now,’ I said. ‘But thank you.’ I did not ask him to clarify what he meant by ‘peaceful’, as he had said the word with such a tone of admiration.

He side-stepped an easel to get to my workbench and started looking through the jumble there, too, picking up a palette knife, examining the crusted blade.

‘Oi! Hands to yourself!’ Pettifer said.

‘Sorry.’ The boy put down the knife and moved away.

‘We don’t mean to be fussy,’ I said, ‘but we’ve got used to things being in a certain order.’ In truth, it would not have mattered if he had upturned the entire workbench and trampled it. Nothing it held was worth protecting any more, only the kind of effluvium that all painters accrue over the course of a long project: dirty turps in peach cans; oils hardening in tubes; rags and palettes congealed with colour; brushes standing in jars of grey water like forgotten flowers. Such ordinary things had lost all meaning for me. I kept them there because I had nowhere else to store them, and they served as a reminder of my limitations. My real work was in those samples on the wall, and I would have cut off the boy’s arm before he touched a single square. But he did not try.

He zipped up his cagoule. The trophies of a hard night’s backgammon distended the front pockets. ‘Well, I’m going to hit the sack. Thanks for the game,’ he said. ‘I thought I would’ve forgotten all my moves by now.’

‘I knew it!’ Quickman slumped into his chair. ‘Hustled!’

‘Blimey. How good are you, exactly?’ Pettifer said.

‘I might’ve played a tournament or two, after hours. You know, backroom games.’

‘For money?’

‘Don’t see the point otherwise.’

Quickman said, ‘I’ve seen those backroom games. They’d never let a kid like you at the table.’

‘Well, they don’t exactly check your age in the places I’m talking about. Not hard to find a cash game in Green Lanes—all the Cypriots round there. You pick things up if you watch them closely. And they’ll talk strategy all night after a few drinks.’

There was something about the way Fullerton spoke—head down and to the side—that did not quite convince me. I just could not imagine him gambling his pocket money in some dismal London pub with a crowd of Cypriots. He was spinning us a story. Quickman must have agreed, because he stroked his beard and said, doubtfully, ‘Green Lanes, eh?’

‘Yup.’ The boy put up the hood of his cagoule, smirking. ‘Thanks for the gum, Knell. I’m sure you’ll get a chance to win it back.’ He yanked at the door. ‘Everyone sleep tight.’ And off he went.

Quickman waited until the boy’s footsteps could no longer be heard, then he stood up and buttoned his coat. ‘There’s something shifty about that lad,’ he said. ‘I don’t know if it’s a good idea to entertain him.’

‘You’re just sore because he thrashed you,’ Pettifer said.

‘Well, all right, perhaps that’s part of it.’ Quickman upturned his collar. The sheepskin was bald and grubby round the neckline. ‘There’s something a bit off about him, though. Am I being unfair?’

‘No—he’s definitely unusual,’ I said. ‘But I thought the same about you once, Q, and it turned out fine in the end.’

It was too soon to claim we had a common understanding, but I could see reflections of my own youth in the way the boy behaved. I was about Fullerton’s age when I first started painting—not yet out of my parents’ house, with barely enough experience of life to qualify me, in the eyes of society, as an expert on anything besides schoolyard gossip and girls’ fashions. But I understood, even then, how much I knew. At sixteen, I had seen enough modern art in picture books to tell a depth from a great hollow. And I reasoned that if so many vapid contributions had been made by artists gone before me, what was there to be frightened of? The precedents of their failure would be my parachute. So I began in this context: without fear, without doubt, without expectation. The year was 1953.

In the last few weeks of school, when other girls were thinking of summer jobs, I stole oil paints from the art-block cupboards at Clydebank High. I prised two window-boards from a derelict outhouse and dragged them home along Kilbowie Road, sawing and sanding them with my father’s tools, stowing them behind a coal box. The pleasure of it—the secret purpose—was so bracing I could not rest. That summer, I committed my entire life to painting.

In the gloomy backcourt of our tenement, as far away as I could get from the stinking middens, I leaned my first board against a wall. I was undaunted by the blankness of it. I did not pause to scrutinise the fabric of the thing itself, to wonder if the woodgrain was right, if the whitewash had set evenly, if it would need to be glazed later on. Instead, I walked up to the board as though it were a boy I had decided to kiss and streaked a layer of phthalo blue across the surface with a palette knife, the floppy baking kind my mother owned, making an impulsive shape upon the wood. There was no history standing on my shoulders then, no classical references hanging in my head like dismal weather. I was alone, uninfluenced, free to work the layers of chalky stolen paint with a big lolloping knife, to smudge with my fingers, pad flat with my fist, pinch, thumb, scrape, and scratch. No judgements of technique arose in my mind, because I did not invite them, did not think to. I simply acted, expressed, behaved, made gestures of the knife that seemed unprompted and divined. There was a scene in my head that I tried to reproduce, something from a wartime story of my father’s, but I could only paint it the way I imagined, not how it really was.

The hours ghosted by. Soon my hands became so colour-soaked and waxed I could not see the pleats of my knuckles or the rims of my fingernails. The dumbshow of the world—that other place I had forgotten, the outer one—broke into road noise and tenement din. Neighbours were squabbling in the close, coming out into the yard with dustpans of ash, telling young lads with footballs to clear off their landings. An early dark was settling and I heard my mother at the window, already home from work. She was calling me. And so I lifted my head to see what I had finished.

There it was upon the wall, drying: a semi-abstract thing, made in a flurry. The suggestion of a place I had never been to. A spray of rain. A slate-grey ocean spattered by bombs. The remnants of a foundry, dismembered in the sky. A falling road bridge, or perhaps a wall, and so much else I did not recognise, which somehow conveyed more in its obliqueness than I could ever have spoken in words.

When my mother came down into the backcourt and saw what I had done, she must have glimpsed my future in it like bad runes. ‘Whitsat?’ she said. ‘Did ye dae that?’ She chided me for wasting a full day on a silly picture and told me to clean her good icing knife. There were better uses for my time, plenty of errands I could do for her. But I spent the next day working on another painting, and the next, and the next, and did not care about the punishments that came after.

Whatever happened to this backcourt spirit? When exactly did it leave me?

I had always wanted more than my parents’ life and its routineness, but I did not take my education seriously enough, and my Leaving Certificate showed only the barest of passes in English and history, ruining any aspirations I might have had to become a teacher. Still, I could not settle for a job in the Singer factory or the biscuit warehouse, as my father had ordained. The afterglow of painting prodded me awake at night, urged me to submit an application to the Glasgow School of Art, told me I could conquer anything if I just applied myself. At the admissions interview, the registrar studied my portfolio and said, ‘Your work is naïve. It leans too much towards abstraction for abstraction’s sake. But it has more intensity than one normally finds in a woman’s painting, and you are still very young. Of course, you won’t be trained in oils until third year—that ought to correct the bad habits you’ve developed.’ A week later, he wrote to offer me a scholarship: We truly hope you’ll accept, the letter signed off, as though I had other choices.

By October, I found myself in colour theory lectures, attending slideshows on the canon; in drawing classes, idly sketching vegetable arrangements; in cold studios, measuring the proportions of nude models against a 2B pencil. My parents’ tenement seemed so far away, and I feared that the ‘intensity’ of my work was being dulled—normalised—by too much refinement of technique. In fact, this attention I paid to the rudiments of drawing and the methods of the Old Masters only heightened my appetite for painting. I made discoveries in these classes that I did not expect: how to imply the mood of a body with a sweep of Conté crayon, how broader narratives could be revealed through compositional decisions. My backcourt spirit survived in all the paintings I made in this period, though my early tutors did not reward it.

It was in the mural department, under the tutelage of Henry Holden, that I began to thrive. I was inspired by the grand traditions of mural painting: from the ice-age pictures in the caves of Lascaux, to the mosaicked churches of Ravenna and Byzantium, the frescos of Giotto, Tintoretto, Michelangelo, Delacroix, and the great political gut-shots of Rivera. In Holden’s tutorials, I felt energised and unhindered. He was a rangy old socialist in half-moon glasses, who gave us curious monthly assignments: Devise a scene for the ballroom of the Titanic. (For this, I painted a ballet of furnace-room labourers in cloth caps, dancing with wheelbarrows of coal, and was marked down for ‘discounting context’.) Paint a scene depicting a work by Shakespeare as it relates to modern times. (For this, I created a swathe of Glasgow tenements with Juliets waiting at every window, graveyards full of Romeo headstones and wounded Mercutios in army uniforms. The picture was kept for the School’s collection, and subsequently lost.)

Holden was the finest teacher I ever had. To ‘avoid any earache’ from the external assessor, he steered us away from the influence of Picasso (‘talent like his can neither be taught nor replicated’), but he allowed us to eschew the mannered ways of easel painting that were sacrosanct to other tutors: the single-viewpoint rule, the vanishing point, chiaroscuro. A great mural, he used to say, was perpetually in conversation with its environment: it should not retreat into the background or vie for attention, but ought to span ‘that invisible line between’. When Holden talked, his words stayed with you. He would twist the tip of his ear while he admired a work-in-progress, as though turning off a valve, and he walked along the building’s topmost corridors racketing his cane against the radiators, or whistling Irving Berlin tunes. Sometimes, he came to drink with us at The State Bar, and would cradle the same small measure of whisky in a glass until closing time.

Holden’s least prescriptive brief came in the fourth year, prior to our diploma show. Complete a mural for a platform at Central Station. There were no limits on theme or materials, he told us. ‘It needn’t convey anything of the railway per se. But, of course, you should think about how the work will be slanted by its location, and vice versa. I want to see your imaginations taking you places. I also want you focusing them where they ought to be. Understand?’

For weeks, I failed to summon a single idea. I spent full days in the studio, numb and depleted, searching for a hint of something true, but any bright intentions I had soon floundered on the pages of my sketchbook. Anxieties began to overrule my normal instincts: what if the backcourt spirit was not enough to sustain me? What if I was never meant to listen to it in the first place? Then Holden came to rescue me. He edged into my workspace, saw the blankness of the canvas I had stretched upon the frame, and said, ‘What’s the matter, Ellie? Have you let the fight go out of you?’

That was exactly how I felt, and I told him so.

‘Then pick a different battle,’ he said. ‘Disturb the peace a bit.’

‘I don’t know how.’

Holden pondered my face, as though seeing it for the first time. ‘Remind me again: are you Catholic?’

‘My mother is.’

‘That wasn’t my question.’

‘Well, I suppose I still believe in God, but not in what the Bible says.’

‘There you are then. Paint what you believe.’

In the moment, his advice seemed so woolly and impractical that I felt even more adrift. Paint what you believe. He might as well have said, Paint the air. But when I got back to my little room-and-kitchen flat and tried to sleep, his words kept pinching at me, until I relented to their meaning. Holden was not telling me to reach inside myself for some pious motivation; he was inviting me to paint the world as I understood it, to convey my own perspective with conviction. The mural should be the picture I would hope to see if I were standing on that platform with my suitcase, waiting for a train to sidle in and carry me away. It should resonate with its location but also transcend it. It should be both personal and public.

I sketched until the light of early morning, making sense of my initial ideas in ink, and finishing with gouache on paper. The next day, Holden found me in the studio, adding a grid of construction lines to the completed image. ‘Ah,’ he said, ‘you’ve finally picked a battle,’ and I did not see him again until the entire twelve-by-three-foot canvas was completed. At the diploma show, modest crowds formed around it. There was head-scratching and consternation. There was excitement. I felt the shift of my trajectory.

What the crowd saw that night was a depiction of an ordinary station platform. The grey-rendered steam of a locomotive swelled from the lower aspect of the canvas. In parts, I had thinned the whorls of paint to near translucence; in others, it cloyed like molasses, in level spots of oil and glaze that almost shone. Amidst the curls of smoke was a rolling horde of men in rags and bedraggled women holding babies. They were clambering from the west side of the platform, stumbling over each other in a tumult, falling headlong. And in the calm space to the east, where the grey mist was dispersing, a figure stood in a baggy pinstriped suit, his body turned, his face unseen, but slightly peering backwards. His right hand was stigmatised and held a crown of thorns. He was barefoot and his tawny hair was greased and combed. A trail of oats was spilling from the briefcase in his other hand. A Bible rested in his top pocket. Beyond him were sunlit pastures fenced off with barbed wire; ships already leaving port; the distant flatline of the sea. I called it Deputation.

The external assessor was so insulted by the picture that he did not deem it worthy of a passing grade. I had sensed that the mural would provoke strong opinions, but I did not expect that it would rouse such ill feeling that the School would deny my graduation. Whilst I was painting Deputation, I daydreamed of installing it at Central Station, imagining the railway manager being invited to the show, falling in love with it. I had taken the trouble of designing it so the canvas could be detached from its stretcher frames and affixed to the brickwork with lead paste, as many of the great muralists in America had been known to do. I had thought—vainly hoped—that it would help me acquire more commissions. Instead, the School gave me two options: repeat the fourth year, or leave without a diploma. I preferred the idea of packing sewing-machine needles with my mother.

At the end of term, as the show was being pulled down, I went in to the studio to collect my things. Henry Holden called me to his office. I sat on his paint-smattered banquette while he rummaged the papers on his desk. There was a reek of whisky about him. ‘I’ve spoken again with the School governors,’ he said. ‘I wish I could say they’d changed their minds.’

‘I’m starting to think it’s for the best.’

He shook his head. ‘Rubbish. You submitted a wonderful painting, and I’m embarrassed those cowards aren’t supporting it. When you go off and make your fortune as a painter, they’re all going to look rather silly. Now—’ He lifted up a folder and gave it a cursory glance before tossing it aside. ‘You might not have seen this in the newspapers, or heard about it on the wireless, but—ah, here we are.’ He unfolded what looked like a grocer’s receipt, skim-reading it. ‘There’s a new travelling fellowship you can apply for.’

‘I really don’t think I’ll be—’

‘Shssh. Listen. This is good news.’ He paused, swallowing drily, and I realised that he was very drunk indeed. ‘Now, I should warn you, the endowment is not much, but it’s been decided, and the committee chairman—namely me—will be most upset if you don’t accept. In fact, he insists that you do. Here.’ He offered me the grocer’s receipt. A name was scrawled on the back in pencil—Jim Culvers—with a number and an address. ‘An old student of mine in London is looking for an assistant. If he doesn’t pay you well enough, give me a ring and I’ll lean on him. It’s not the same as a diploma, or even a proper fellowship, I know—but, anyway, those are his details.’

I felt as though I should kiss him. ‘You don’t have to do this for me, Henry.’

‘I’m aware.’

‘I don’t think I really deserve it.’

‘Then give it back, I’ll tear it up for you.’ He creaked forward on his chair, turning out his palm. I would always remember this moment with Holden, how he looked at me with certainty, knowing I would not release the paper to him. ‘Thought not,’ he said, and withdrew his hand. ‘It’ll take Jim a while to notice you’re a better painter than he is. When that happens, move on. Until then, I suspect the two of you will get on famously. He’s already expecting you.’

If I had chosen differently, and carried out my plan to take a factory job alongside my mother, I might never have painted again. But how much worse off would I have been to live without art than to have it consume me and spit out my bones? There are still days when I count up all the sewing-machine needles I could have packed instead.
