Margaret Ilsley had spent nineteen years locked behind four iron bars, hidden from the world as a madwoman by the aunt who once saved her life — until a duke on a black horse stopped in the road below her window, looked up, and did not look away.

PART 4

His name was Steven Carr, Duke of Wexford, and what he did with the next six weeks was, by his own later account, the only genuinely intelligent thing he did in the whole affair.

Nothing whatever.

He wrote to his own steward that first night from an inn four miles on, and what he wrote was not an accusation but four questions: Who owned Ashgrove? Who had owned it before? What had become of the Ilsley property, if there was one? And had anyone in that village laid eyes on the young lady of that house in the last ten years?

He did not write to a magistrate. He turned it over for the better part of an hour and concluded, without knowing it, precisely what Margaret herself had worked out two years earlier in the margin of a book: that a duke writing to a magistrate would send the magistrate straight to the door, and Mrs. Kelsol would receive him with perfect composure and say the young lady was ill and confused, and there would be nothing whatever in the world to set against that — and the household would have a month’s warning to make the truth disappear before anyone official ever crossed the threshold.

So he waited. And he was honest with himself about what the waiting cost.

The answers came back in nine days, and they were worse than he had expected. Ashgrove was not Mrs. Kelsol’s at all. It had been Margaret Ilsley’s own property since her mother died, nine hundred a year in three parishes. Prudence Kelsol was her step-aunt, appointed guardian of the person and estate by the court when the child was nine years old — and no one in the village had seen Margaret Ilsley in fifteen years. Two people had believed her dead until his man began asking.

The final line of the letter, he read some nine times over. Your Grace will forgive me for adding that Miss Ilsley must now be eight-and-twenty years of age, and that a guardianship determines at one-and-twenty, and that I can discover no commission of lunacy ever taken out or applied for in that county.

He sat with that in his own library for a long time, and said, to nobody at all, Seven years.

Inside the house, Margaret had spent those same nine days composing seven lines she would spend nine hours getting exactly right.

She wrote them to Mrs. Dowset, the rector’s wife of Ashgrove parish — a woman she had never met, whose name she had found by accident in a four-year-old newspaper, and whose existence she had been saving for two years against exactly this moment. She did not ask for help. That, she understood, was the whole of the art of it.

Madam, I am Margaret Ilsley of Ashgrove. I am eight-and-twenty years old, and I am confined to an upstairs room in this house, and have been since I was nine, and my aunt tells the county I am unwell. I am not asking you to believe me — I am aware that you cannot, and I should not, in your place. I am asking you to write to me. Not to my aunt. To me, at this house, by name, sealed. If such a letter comes and my aunt keeps it from me, she will have done a thing that can be described.

The part she had not been able to solve in two years of turning it over was how to get it out of the house.

She solved it on a Thursday morning, and the way she solved it was by not asking Susan Row to carry it at all.

Miss, I want to say four things, Susan had said in the doorway, tray still in her hands, before Margaret could speak. And then I shall not say them again.

She said them. That four servants had been dismissed from that house in nineteen years for asking about the upstairs room, and she knew every name, and had told no one. That she was five-and-forty with two children and nowhere else within nine miles to go, and Margaret had thought of that every single time she had wanted to ask her for anything. That Margaret was eight-and-twenty, not confused, had read every book in that corridor four times over, and that her aunt had not been her lawful guardian for seven years and did not know it.

And the fourth, Susan Row said, is that there is a letter under the corner of that mattress, and I am not asking you to carry it, and I want that understood. I am telling you it is there. If it is gone tomorrow and I never learn what became of it — that will suit me perfectly well.

She did not say another word. She put the tray down, and went out, and the key turned.

Margaret sat on the edge of the bed with her hands shaking too hard to hold a pen, and understood that she had just done the only thing left in her power, and that she would not know for days — perhaps ever — whether it had worked, and that if it hadn’t, she had shown her entire hand to a woman who could walk downstairs and undo her in a sentence.

The letter was gone the next morning. Susan Row said good morning, miss, set down the tray, and did not look at her, exactly as she had not looked at her for nine years.

Neither of them spoke of it again for four months.

What Susan Row actually did with those four folded sheets, tucked into her own stays, was carry them for nine days — through bed-making, through trays, through supper in the servants’ kitchen — and twice come within an inch of burning them, and once hold the pages over the range at five in the morning before her nerve failed her.

On the ninth day, her sister walked over from the next village, as she did once a month, and Susan pressed the letter into her hand at the garden gate.

Put that through Mrs. Dowset’s door, she said. And do not tell me you have.

And that — a fact nobody had engineered, a fortune nobody could have arranged in four years of trying — was how the letter reached the one person outside that house who could not simply be told there was nobody at the window.
