I stared groggily around the unfamiliar room, at the heavy burgundy drapes, designed to block out light, at the large flat-screen television, at my overnight bag, which I hadn’t even bothered to unpack. I checked the clock, which said it was shortly after seven Swiss time. And as I realized where I was, I suddenly felt my stomach clench with fear.

I scrambled out of bed just in time to be sick in the little bathroom. I sank down on the tiled floor, my hair sticking to my forehead, my cheek pressed against the cold porcelain. I heard my mother’s voice, her protests, and I felt a dark fear creeping over me. I wasn’t up to this. I didn’t want to fail again. I didn’t want to have to watch Will die. With an audible groan, I scrambled up to be sick again.

I couldn’t eat. I managed to swallow down a cup of black coffee and showered and dressed, and that took me to 8am. I stared at the pale-green dress I had thrown in last night and wondered if it was appropriate for where I was going. Would everyone wear black? Should I have worn something more vibrant and alive, like the red dress I knew Will liked? Why had Mrs Traynor called me here? I checked my mobile phone, wondering whether I could call Katrina. It would be seven in the morning there now. But she would probably be dressing Thomas, and the thought of talking to Mum was too much. I put on some make-up and then sat down by the window, and the minutes ticked slowly past.

I don’t think I had ever felt lonelier in my life.

When I couldn’t bear being in the little room any longer, I threw the last of my things into my bag and left. I would buy a newspaper, and wait in the lobby. It couldn’t be worse than sitting in my room with the silence or the satellite news channel and the suffocating darkness of the curtains. It was as I was passing reception that I saw the computer terminal, discreetly placed in a corner. It was marked: For Use Of Guests. Please Ask At Reception.

‘Can I use this?’ I said to the receptionist.

She nodded, and I bought an hour’s token. I knew suddenly very clearly who I wanted to speak to. I knew in my gut that he was one of the few people I could rely on to be online at this time. I logged on to the chat room and typed on the message board:

Ritchie. Are you there?

Morning, Bee. You’re early today?

I hesitated for just a moment before typing:

I am about to begin the strangest day of my life. I am in Switzerland.

He knew what it meant. They all knew what it meant. The clinic had been the subject of many heated debates. I typed:

I’m frightened.

Then why are you there?

Because I can’t not be here. He asked me. Am in hotel waiting to go see him.

I hesitated, then typed:

I have no idea how this day is going to end.

Oh, Bee.

What do I say to him? How do I change his mind?

There was a delay before he typed again. His words appeared on the screen more slowly than usual, as if he were taking great care.

If he’s in Switzerland, Bee, I’m not sure he’s going to change his mind.

I felt a huge lump in my throat, and swallowed it. Ritchie was still typing.

It’s not my choice. It’s not the choice of most of us on this board. I love my life, even if I wish it was different. But I understand why your friend might well have had enough. It’s tiring, leading this life, tiring in a way the AB can never truly understand. If he is determined, if he really can’t see a way of things being better for him, then I guess the best thing you can do is just be there. You don’t have to think he’s right. But you do have to be there.

I realized I was holding my breath.

Good luck, Bee. And come see me after. Things may get a little bumpy for you afterwards. Either way, I could do with a friend like you.

My fingers stilled on the keyboard. I typed:

I will.

And then the receptionist told me that my car had arrived outside.

I don’t know what I expected – maybe some white building next to a lake, or snow-capped mountains. Perhaps some medical-looking marble frontage with a gold-plated plaque on the wall. What I didn’t expect was to be driven through an industrial estate until I arrived at what looked remarkably like an ordinary house, surrounded by factories and, weirdly, a football pitch. I walked across decking, past a goldfish pond, and then I was in.

The woman who opened the door knew immediately who I was looking for. ‘He is here. Would you like me to show you?’

I stalled then. I stared at the closed door, oddly similar to the one I had stood outside in Will’s annexe all those months ago, and I took a breath. And nodded.

I saw the bed before I saw him; it dominated the room with its mahogany wood, its quaintly flowered quilt and pillows weirdly out of place in that setting. Mr Traynor sat on one side of it, Mrs Traynor on the other.

She looked ghostly pale, and stood up when she saw me. ‘Louisa.’

Georgina was seated on a wooden chair in the corner, bent over her knees, her hands pressed together as if in prayer. She lifted her gaze as I walked in, revealing shadowed eyes, reddened with grief, and I felt a brief spasm of sympathy for her.

What would I have done if Katrina had insisted on her right to do the same?

The room itself was light and airy, like an upmarket holiday home. There was a tiled floor and expensive rugs, and a sofa at the end that looked out on to a little garden. I didn’t know what to say. It was such a ridiculous, mundane sight, the three of them sitting there, as if they were a family trying to work out where to go sightseeing that day.

I turned towards the bed. ‘So,’ I said, my bag over my shoulder, ‘I’m guessing the room service isn’t up to much?’

Will’s eyes locked on to mine and despite everything, despite all my fears, the fact that I had thrown up twice, that I felt like I hadn’t slept for a year, I was suddenly glad I had come. Not glad, relieved. Like I had excised some painful, nagging part of myself, and given it over.

And then he smiled. It was lovely, his smile – a slow thing, full of recognition.

Weirdly, I found myself smiling back. ‘Nice room,’ I said, and immediately realized the idiocy of the remark. I saw Georgina Traynor close her eyes, and I blushed.

Will turned towards his mother. ‘I want to talk to Lou. Is that okay?’

She tried to smile. I saw a million things in the way she looked at me then – relief, gratitude, a faint resentment at being shut out of these few minutes, perhaps even a distant hope that my appearance meant something, that this fate might yet be twisted from its tracks.

‘Of course.’

She moved past me into the corridor, and as I stood back from the doorway to let her pass, she reached out a hand and touched my upper arm, just lightly. Our eyes met, and hers softened, so that briefly she looked like someone else entirely, and then she turned away from me.

‘Come, Georgina,’ she said, when her daughter made no attempt to move.

Georgina stood slowly and walked out silently, her very back broadcasting her reluctance.

And then it was just us.

Will was half propped up in the bed, able to see out of the window to his left, where the water feature in the little garden merrily trickled a thin stream of clear water below the decking. On the wall was a badly framed print picture of dahlias. I remember thinking that was a really crummy print to have to look at in your last hours.

‘So … ’

‘You’re not going to –’

‘I’m not going to try and change your mind.’

‘If you’re here, you accept it’s my choice. This is the first thing I’ve been in control of since the accident.’

‘I know.’

And there it was. He knew it, and I knew it. There was nothing left for me to do.

Do you know how hard it is to say nothing? When every atom of you strains to do the opposite? I had practised not saying anything the whole way from the airport, and it was still nearly killing me. I nodded. When I finally spoke, my voice was a small, broken thing. What emerged was the only thing I could safely say.

‘I missed you.’

He seemed to relax then. ‘Come over here.’ And then, when I hesitated. ‘Please. Come on. Right here, on the bed. Right next to me.’

I realized then that there was actual relief in his expression. That he was pleased to see me in a way he wasn’t actually going to be able to say. And I told myself that it was going to have to be enough. I would do the thing he had asked for. That would have to be enough.

I lay down on the bed beside him and I placed my arm across him. I rested my head on his chest, letting my body absorb the gentle rise and fall of it. I could feel the faint pressure of Will’s fingertips on my back, his warm breath in my hair. I closed my eyes, breathing in the scent of him, still the same expensive cedar-wood smell, despite the bland freshness of the room, the slightly disturbing scent of disinfectant underneath. I tried not to think of anything at all. I just tried to be, tried to absorb the man I loved through osmosis, tried to imprint what I had left of him on myself. I did not speak. And then I heard his voice. I was so close to him that when he spoke it seemed to vibrate gently through me.

‘Hey, Clark,’ he said. ‘Tell me something good.’

I stared out of the window at the bright-blue Swiss sky and I told him a story of two people. Two people who shouldn’t have met, and who didn’t like each other much when they did, but who found they were the only two people in the world who could possibly have understood each other. And I told him of the adventures they had, the places they had gone, and the things I had seen that I had never expected to. I conjured for him electric skies and iridescent seas and evenings full of laughter and silly jokes. I drew a world for him, a world far from a Swiss industrial estate, a world in which he was still somehow the person he had wanted to be. I drew the world he had created for me, full of wonder and possibility. I let him know a hurt had been mended in a way that he couldn’t have known, and for that alone there would always be a piece of me indebted to him. And as I spoke I knew these would be the most important words I would ever say and that it was important that they were the right words, that they were not propaganda, an attempt to change his mind, but respectful of what Will had said.

I told him something good.

Time slowed, and stilled. It was just the two of us, me murmuring in the empty, sunlit room. Will didn’t say much. He didn’t answer back, or add a dry comment, or scoff. He nodded occasionally, his head pressed against mine, and murmured, or let out a small sound that could have been satisfaction at another good memory.

‘It has been,’ I told him, ‘the best six months of my entire life.’

There was a long silence.

‘Funnily enough, Clark, mine too.’

And then, just like that, my heart broke. My face crumpled, my composure went and I held him tightly and I stopped caring that he could feel the shudder of my sobbing body because grief swamped me. It overwhelmed me and tore at my heart and my stomach and my head and it pulled me under, and I couldn’t bear it. I honestly thought I couldn’t bear it.

‘Don’t, Clark,’ he murmured. I felt his lips on my hair. ‘Oh, please. Don’t. Look at me.’

I screwed my eyes shut and shook my head.

‘Look at me. Please.’

I couldn’t.

‘You’re angry. Please. I don’t want to hurt you or make you –’

‘No … ’ I shook my head again. ‘It’s not that. I don’t want … ’ My cheek was pressed to his chest. ‘I don’t want the last thing you see to be my miserable, blotchy face.’

‘You still don’t get it, Clark, do you?’ I could hear the smile in his voice. ‘It’s not your choice.’

It took some time to regain my composure. I blew my nose, took a long deep breath. Finally, I raised myself on my elbow, and I looked back at him. His eyes, so long strained and unhappy, looked oddly clear and relaxed.
