Turtles don’t have nations. Or flags. Or strategic nuclear weapons. They don’t have terrorism or referendums or trade wars with China. They don’t have Spotify playlists for their workouts. They don’t have books on the decline and fall of turtle empires. They don’t have internet shopping or self-service checkouts.

Other animals don’t have progress, they say. But the human mind itself doesn’t progress. We stay the same glorified chimpanzees, just with ever bigger weapons. We have the knowledge to realise we are just a mass of quanta and particles, like everything else is, and yet we keep trying to separate ourselves from the universe we live in, to give ourselves a meaning above that of a tree or a rock or a cat or a turtle.

So here I am, with my head full of human fears and pains, my chest tight with anxiety, thinking about how much future I have in front of me.

I am lucky these days if I manage three hours of sleep. In the old days I used to take Quieting Syrup – a kind of cough mixture recommended by Hendrich – but Quieting Syrup contained morphine, and so they stopped making it when they prohibited opiates a hundred years ago. So now I have to make do with Beecham’s Night Nurse, which never really hits the spot.

I should have gone to the doctor, of course, but I didn’t. It was a rule of the Albatross Society. No doctors. Not for anything. And it was easy, after my guilt over Dr Hutchinson, to follow this through. I have wondered if it was a tumour, though I have never heard of an alba having a tumour. And obviously if I have one it would be very slow-growing. One that would give me at least an average human lifespan ahead of me. But no, the symptoms aren’t even close.

Anyway, the headache is there with only one day to go before the new job. I drink some water and eat some cereal and then I take Abraham for a walk. He had spent the night eating the arm of the sofa but I don’t want to judge him. He has enough issues already.

I suppose I needed a dog with problems, in order to think less about my own. Akitas were made for the Japanese mountains, so I knew that he was a comrade of sorts, someone made for more noble surroundings, reduced to the grime and pollution and concrete streets of east London. No wonder he pissed on the carpet and ate the sofa. This wasn’t the life he’d asked for.

So we walk along, myself and Abraham, with all the exhaust fumes in our faces.

‘There used to be a well here,’ I tell him, as we pass a betting shop. ‘And here, right here, that’s where all the men used to play skittles after church on a Sunday.’

A teenage boy passes us, in turned-up trousers and an oversized ‘The Hundreds’ T-shirt, looking like an oblivious distant echo of a seventeenth-century London boy of his age in rhinegrave breeches and overskirt. The boy looks up from his phone and glances at me with quizzical and disapproving eyes. To him I am just another loose-screwed London loner, talking to myself. Maybe he is going to be one of the pupils I will be teaching on Monday.

We cross over the road. We pass a lamppost with an advert tied to it. THE CANDLELIGHT CLUB. Relive the Roaring Twenties at London’s top speakeasy-themed cocktail bar. My headache intensifies, and I close my eyes and a memory rises like a cough – playing ‘Sweet Georgia Brown’ at Ciro’s piano bar in Paris, with a stranger’s hand resting softly on my shoulder.

I am in the park now. I hadn’t played the piano for years, I realise. I am fine with that, most of the time. I have long convinced myself that the piano is like a drug, seductive and strong, and it can mess you up, it can awaken dead emotions, it can drown you in your lost selves. It is a nervous breakdown waiting to happen. I wonder if I will ever play again. I unclip the lead from Abraham’s collar and he stays by my side and looks up at me, confused, as if perplexed by the concept of freedom.

I relate.

As I stare around the park I see a man with a Bichon Frise discreetly scoop up shit with a plastic bag. A squirrel darts in jerky zigzags up the trunk of a beech tree. The sun climbs out from behind a cloud. Abraham trots away.

It is then that I notice her.

A woman sitting on a bench, reading, a short distance away. I recognise her, which itself is rare. I hardly pay much attention to what people look like any more. Faces blur into other faces. But I know instantly this is the woman I saw out of the window of Daphne’s office. The French teacher. As then, she seems wholly herself. It takes a lot to be unique in a species of so many. She has style. I don’t mean in what she is wearing (corduroy blazer, jeans, glasses), though that is perfectly fine. I mean in the easeful way in which she places the book down beside her on the bench and stares around at the park. In the way she puffs out her cheeks a little and blows and closes her eyes and tilts her head up to invite the sun. I look away. I am a man in a park looking at a woman. I could be anyone. It isn’t 1832 any more.

But then, as I look away from her, she calls over.

‘Your dog is lovely.’ She has a French accent. The new French. Yes. It is definitely the same woman I had seen. She holds out the back of her hand for Abraham to smell. Abraham licks his gratitude, and even wags his tail.

‘You’re honoured.’

And then she looks up at me in a rather unsettling way. A little too long. I am not arrogant enough to believe I am so attractive it is difficult for her to turn away. In reality, I haven’t had those sort of looks from anyone for at least a hundred years. In the 1700s, when I looked in my twenties and wore my grief like a scar, I was often the subject of long, lingering gazes, but not these days. No. She is looking at me for another reason. And that troubles me. Maybe she had seen me too, at the school. Yeah. That was probably it.
