And so we sit for cards.

'And what are the stakes, tonight?' asks Stewart. 'Another story? A kiss?'

So he can sense it, too. Francine does not even blush. My friend leans back from the table and casually gropes for the decanter behind him. I bustle around and serve him myself. I say it is too dull – Mr Whytehead is to blame; we must play for money, because what is an evening without the promise of ruin? I turn to my dear friend and I say, 'You must give Mr Whytehead more money, my dear, so that he can overcome his scruples and play. (I think I am a little drunk.) Or give the maid money, at least, so we can have a proper game.'

It seems I have stumbled on a solution. And a charming one at that. My friend looks at me, and lifts his glass. And so he is pleased with me, at last.

'Here's to the generosity of Madame Lynch.'

And he shouts through the open door for, 'Money!'

We play just as we were some nights ago. My friend looks at his hand in easy contemplation. Stewart is massive again, heaving and glowering over two hearts and a spade. Across the table, Whytehead leans stiffly in, over the shoulder of the trembling maid.

From time to time, he whispers. And once, he points.

So at least I have some pleasure. To see the girl hazard more than she could earn in a year. To see her handle it – the heft and clink of it in her palm, the gathering feel of the metal rims as they slither into a column between finger and thumb, which she then sets down on the baize. The hand withdrawn. So careful.

I can see a vein flutter on her neck.

I know money. I know the value of, for example, three hundred pounds – how a maid could live a lifetime on such a sum, how my father could live a month, how my mother might have raised her children on it for more than a year. I burned a note, once, that belonged to Mr Bennett. A fifty. I said to him, as I did it, 'This afternoon, I think I'll love you for free.'

These are the things I could tell the maid as she makes a timorous throw into the centre of the table, and then flinches when one of the coins begins to roll. I could tell her, as she loses, hand after hand, a modest dowry – which is to say, a life; a husband, a child she might keep – that money is the least of it, my dear.

And my goodness, she does lose. It takes a little over an hour. It takes a minute at a time. Whytehead leans over her shoulder, his superior mind in a welter of calculation, and is no use to her. Stewart, who bets promissory notes on his future salary, takes her money too. He reaches over and pulls it across the baize: once, twice. He takes it five times or more. The solid fact of it goes into his pocket when the game is done. Which it is done when the maid has nothing left to lose.

Ί have the best of it, tonight, it seems,' says Stewart, all good humour – as though she might get it back from him, another time. Then he makes his way to the decanter, with ponderous regret. But his hand trembles, as he pours.

My dear friend smiles, and excuses himself to smoke outside. No one follows him. Perhaps because they were not asked. But still – Stewart, who eats cigars, who has a passion for them, runs a finger over the cut of the crystal in his glass. Whytehead, who sticks so religiously to my husband's side, has, it seems, finally become unglued. And it amazes me again, how we make way for other people's desire.

Even I am unmanned by it, until I say,

'You may go.'

She picks herself up and she walks, not towards the stateroom where my clothes need laying out for the night, but into the open air.

He is not my husband. Of course he is not. I must train my turn of phrase. The man who is not my husband comes back fifteen minutes later – I have counted it by the clock. His cigar is still lit, though now it is a stub that he chucks, unceremoniously, out the porthole window on the far side of the room.

'And why is it', I ask, 'that a man must come inside to fire the butt of his cigar through a window, when he has the whole vast river to throw it into, over the rail?' I say that he must have the satisfaction of the porthole, because men must always be throwing things; but more than that, they must be aiming them too – and the smaller the target, or in this case the hole, the better.

Everyone laughs. My friend looks at me with a new admiration. And I quite frankly meet his eye. It is as though we have done this thing together. And this makes me feel lonely and quite giddy, both at the same time.

Later, Francine comes to unlace me in the dark. I have fallen asleep in a chair, because to lie down seems to strangle the child, or strangle me, one or the other. So she whispers quite close to me and heaves me a little forward to get at the hooks and then the stays.

I groan a little. And, in my sleep-weakened state, all I can think of is the closeness of her belly to me and the hope that there is not a child in her too. I can smell him off her, and this makes me gag a little. Because in the bargain, whatever it was, there was nothing agreed about smell.

And then she has me undressed and under the bedclothes, free of my corset, and happy as a boiled egg, all peeled.

In the middle of the night, I stir and find he is not yet come to bed. It is some time before I remember why this might be, and when I do I am awake and raging. He must not sleep with her. These hours, I think, are meant to punish. And, if so, he will be punished in return. Because he has started the wrong game here. He has started a small game and I am hugely, wildly bored by the small game. I was not sure I wanted to play, but if needs must, then I will play big.

Such is my ambition, in the middle of the night.

I hear the darkness breathe and stir; an animal close to my ear. I never sleep alone. I had Francine crawl in with me in Paris, when there was no man in the bed (I can hardly call for her, now). Because there was always my sister and, when my sister bolted, there was any number of girls at Mme Hubert's. The first, the only, nights I spent alone were in that inn, when Mr Bennett brought me to Paris.

Or did not bring me to Paris. He was sick with something like grief – stiff with it, in the corner of the post we took. It was as though his back would not bend into the angle of the seat. He looked at me while I gazed out the window or played with the cards I had in a little walnut box; clever things – three children playing with their kites made up the three of hearts, I remember; though all the ones I turned were spades, with women weeping, and skeletons.

'Your fate,' I said, flicking them into Mr Bennett's poor lap – mostly to amuse the man who shared the post with us, a fat fellow with a glazed eye. Mr Bennett was, by that time, so maddened by the presence of men around me that it turned the ends of his fingers blue, and I hoped he would not die before we got to Paris, which is to say, before my fortune was made. I was fourteen. We passed though Orléans and I could smell Paris on the road. I could see the smoke of it ahead of us; there was a smudge of Paris on the clear blue sky.

We stopped a night in Artenay, and Mr Bennett, out of jealousy, I thought, locked me in my room. I do not know when he left. He may have stayed to take some supper. The innkeeper had instructions for me to stay where I was – the bill was already paid.

This I found out in the morning, after a night of horror. Then another. And a third. They left me like that, as you might lock up a dog; the better it will love the man who sets it free. I think about it still. I had money – quite a lot of money – in my trunk and variously hidden in my clothes. I was not, after the first night, locked in. And still I craved the rescuing knock. And then it came.

It was the fat man who took the post with us. His name was M. Raspail.

The baby turns. If it is a girl, I will drown it, that is all.
