CHAPTER 07: YARROW: THE LADY WITH THE LAMP

The yarrow is the oldest wound herb there is, and it is named after a soldier. Armies carried it in their packs for three thousand years before anybody could say what it did or why, and it was still in the packs long after the physicians had stopped believing in it, because the men would not give it up. It is a weed. It will grow in a cart rut. That is most of the reason it has saved more lives than any garden in the world.

The boy's name was Tem, and he was eleven, and he cut his leg with a scythe in the hayfield in the July she turned eight.

It was not a bad cut. That was the thing. It was not even the worst cut anybody got that week, because haymaking is a fortnight of people swinging blades in a hot field while tired, and the estate infirmary expected a certain quantity of it and had a shelf of bandages ready for the season.

He walked back on his own legs. The cut was along the outside of the calf, about the length of a hand, and it was clean, and the physician looked at it and was satisfied and closed it with nine stitches and packed it with a wool dressing and a grease that had been made up in the stillroom to a recipe that was four hundred years old.

Theresia was there because she was everywhere that summer. She had a notebook and a permanent expression of enquiry and the entire household had given up trying to keep her out of rooms.

She watched the physician do it. She watched him take the needle out of the roll where it had been since the last patient. She watched him wipe his hands on the front of his apron before he began, which was the apron he had been wearing all afternoon, and she watched the wool dressing come off a length that had been sitting open on a shelf in a hot room since spring.

And she said nothing, because she was eight, and because the man was competent and careful and doing exactly what four hundred years of medicine told him to do, and because everything she knew was unsayable.

Tem was fine for three days.

On the fourth day the leg was hot. On the sixth it had swelled past the stitching and the physician opened it again, correctly, to let it drain, and packed it again with the same wool off the same shelf. On the eighth there were red lines going up the inside of the thigh, and the boy's mother was sent for. On the eleventh day he died, and the certificate said mortification of the limb, and the physician wrote it in good faith because that is exactly what had happened.

Theresia went home and sat in her room and did not come down for dinner, and when Miriam came up she said she had a headache, and it was the first time she had lied to Miriam in her life.

She had known on the first afternoon, standing in that room with her notebook, watching a needle come out of a cloth roll.

She had known and she had not said a word, because what exactly was she going to say. That there were animals in the world too small to see. That they were on his hands, and on the wool, and in the grease, and that they had gone into the boy's leg with the needle and had eaten him from the inside over eleven days while everybody in the room did their best.

She could hear how it sounded. She had eight years of practice at hearing how things sounded before she said them, which was the only reason anybody in this world still thought she was ordinary.

So she had said nothing, and Tem had died, and she had learned something about herself that she did not like at all, which was that she had a threshold, and that below it she would keep her mouth shut and let a boy die rather than be laughed at.

It took her a year and a well full of cold water before she was ready to go back to it.

—=<>=—

She tried the truth exactly once.

It was in the autumn of her ninth year, in the estate infirmary, with Master Aurel Venn, who had come out from Vellhorn to take over the district after the old physician retired.

Venn was not a fool. She wanted that understood, and she said so for the rest of her life whenever the story came up, because the story got told badly and in the badly told version he was a pompous obstacle and that was a lie.

He was fifty, careful, unhurried, and genuinely learned in a discipline that had been getting things wrong with great rigour for four centuries. He had read everything available. He kept records, which almost nobody did. He washed, because he was fastidious, though not between patients and not for any reason connected to the patients. He had turned down a post in the capital because he thought district work was more useful, and he had been right.

She laid it out for him properly. She had rehearsed it for a week.

She said that she believed there were living things too small for the eye, present on skin and cloth and in the air, and that some of them, introduced into a wound, would multiply inside a person and produce exactly the sequence they both saw every summer: heat, swelling, the sweet smell, the red lines, the fever, the death.

She said she could not prove it. She said she knew how it sounded.

Master Venn listened to all of it without interrupting, which was more than she had expected. He asked two questions, both of them good. Then he said, in a tone of real kindness, which was what made it so much worse:

"My lady, you are a remarkable child and I say that without flattery. But you have described a thing that cannot be seen, cannot be weighed, cannot be caught and cannot be shown, and which explains the death. So does the imbalance of the humours. So does bad air. So does a wound taking a chill. Four explanations, all of which fit, none of which can be tested." He folded his hands. "When a theory explains everything and predicts nothing, it is not yet knowledge. It is a story that makes us feel better. Physicians have a great many of those and we do not need a fifth."

Theresia sat in that room and understood, with a clarity that was almost physical, that she had just been comprehensively out argued by a man who was completely wrong.

"That is a very good answer," she said.

"It is the only honest one I have."

"Then I shall stop telling you why," said Theresia, "and I shall show you what instead."

Master Venn smiled at her, the way men smile at clever children.

He was still apologising for that smile eleven years later at a dinner in the capital, and she told him every single time that there was nothing to apologise for, and he never believed her.

CHAPTER 07: YARROW: THE LADY WITH THE LAMP: 02

The proposal she brought him four months later contained no invisible animals at all.

It contained a procedure, six pages of it, and a way of finding out whether the procedure was worth anything.

The procedure was this. Instruments to be boiled in water for a quarter of an hour before use and kept in a closed vessel until the moment of use. Linen for dressings to be boiled, dried, folded and stored sealed, and a sealed packet once opened to be used within the day or boiled again. Hands to be washed in strong spirit before touching a wound, and again between one patient and the next, without exception, including when the physician is certain that he has touched nothing. Wounds to be flushed with boiled water, and where the flesh is torn, left open and dressed rather than closed tight over. Aprons changed daily. The floor of the ward washed with lime.

No theory. It was Six pages of things to do with your hands.

"And you propose," said Master Venn, "to find out whether it makes any difference?"

"I propose that you find out," said Theresia. "I am nine. If I run it, the result belongs to a child and every man in the profession will explain it away in an afternoon. If you run it, the result belongs to you."

He looked at her over the top of the pages for a long moment.

"You are managing me."

"Yes," she said. "Comprehensively. Is it working?"

The trial ran at the garrison infirmary at Vellhorn, because Vellhorn had four hundred soldiers in it and soldiers produce a steady, reliable and depressing volume of injury: training cuts, crush injuries from the ground dragon lines, road patrol wounds, the occasional genuine fight. It ran for seven months. It was the single most boring thing Theresia van Astrea had ever been involved in and she loved every hour of it.

Two wards. Cases assigned by the order in which they came through the door and by nothing else, which was her condition and which Venn accepted immediately and enforced against two separate captains who tried to get their own men into the ward with the reputation.

The east ward did everything the way it had been done for four hundred years.

The west ward did the six pages.

She was there for all of it. She lived in a garrison town for seven months at nine years old, in a room over a saddler's with Miriam sleeping across the door and a standing guard of two that Thames had insisted on and that she had negotiated down from six.

And she walked the west ward at night.

That was not a decision. It was the same compulsion that had kept her in Ganner's workshop for five months and in the garden until the lantern guttered. She could not sleep in a strange town, and a ward at two in the morning is a place where something is always slightly wrong, and she had six pages of procedure that depended entirely on tired people doing tedious things correctly at hours when nobody is watching.

So she watched. With a lamp, because the garrison did not light the wards at night and she needed to see hands.

She checked that the instrument vessel was closed. She checked that the opened linen packet had the day's mark on it. She checked, eleven times a night, that the spirit basin had spirit in it and not water, because on the ninth day she had found it topped up with water by an orderly who had run out and had not wanted to report it.

She talked to the men. That was not part of the procedure and it turned out to be the most important thing she did.

A soldier at two in the morning with a bad leg and a fever will talk to anybody, and they talked to her, and she wrote down what they said, and by the fourth month she had a list of eleven things wrong with the process that were not in her six pages and that no physician would ever have discovered, because no physician is in a ward at two in the morning being told the truth by a frightened man.

The men took to her. Of course they did. She was nine, she was clearly somebody's daughter, she did not flinch, she brought food she had cooked herself because the garrison kitchens were a war crime, and she came every single night.

The name started with them. She never found out which one of them said it first, and she asked, later, when it mattered, and got four different answers.

The lady with the lamp.

It was in the barracks before it was anywhere else. It went from the barracks to the town, and from the town into a letter, and from the letter into the capital, and by the time the Crown got hold of it, it had been in soldiers' mouths for a year and a half and was beyond anybody's power to withdraw.

—=<>=—

The tally came out in the eleventh month, because Venn insisted on following every case to its end and would not report on the living.

Theresia was not in the room when he read it. She had deliberately arranged not to be, because she had understood by then what this was going to do to him and had decided that he was entitled to have it happen in private.

He worked it out in his own hand, in his own ward office, with the door shut, for three hours.

Of the wounds treated in the east ward, a little over one in four went bad in the manner they all recognised, and of those, rather more than half the men died or lost the limb.

In the west ward it was under one in twenty, and two men died, and both of those had arrived already septic from a road patrol four days out.

The difference was not subtle. It was not a matter of interpretation or of a clever reading of the figures. It was an enormous, ugly, unmissable gulf, and it had been produced by boiling linen and washing hands.

Master Aurel Venn came out of that office at some point in the evening and found a nine year old girl sitting on the steps of the infirmary in the dark with a lamp beside her, waiting.

He sat down on the step next to her, which was not a thing a physician of his standing did in a garrison yard, and he put the sheet on his knee, and neither of them said anything for a while.

"How many summers?" he said eventually.

"I am sorry?"

"How many summers have I been doing it the other way..." He was not looking at her. "Twenty six. I have kept records for twenty two of them because I thought myself modern. I could go and get them. I could sit down tonight and I could put a number on it."

"Master Venn..."

"I should like to know whether you can tell me not to."

Theresia looked out across the dark yard at the ground dragon lines.

"No," she said. "I cannot tell you not to. You are going to do it whether I tell you or not, and it will be an extremely large number, and it will be with you for the rest of your life."

"That is a hard thing to say to a man."

"You said a hard thing to me in the autumn," said Theresia, "and it was correct, and I have thought about it every day since, and I am better for it. I am returning the favour. Everybody else in your profession is going to tell you that you could not have known. That is true and it is useless, and if you let them say it often enough you will start believing that the not knowing was somebody else's fault."

Venn laughed, very shortly, with no humour in it at all.

"You are nine."

"So people keep telling me."

He sat with the sheet on his knee.

"I am going to write it up," he said at last. "Under my own name. That is not modesty on your behalf, my lady, so do not thank me for it. It is the opposite. If your name is on this paper, then it is a curiosity produced by the strange child of the Astrea house and every physician in this kingdom will read it as gossip and file it. If my name is on it, it is a clinical trial conducted at a royal garrison by a district physician of twenty six years' standing, and they will hate it, and they will have to argue with it, and arguing with it is all I require."

"I know," said Theresia. "That is why I asked you and not somebody who would have been grateful."

Master Venn turned his head and looked at her for a long moment in the lamplight.

"Does anything ever happen to you by accident?" he said.

"Yes," said Theresia van Astrea. "Almost everything. This is the only part I get to choose."

—=<>=—

The paper went out in the spring. It was ignored for eleven months and then it was not ignored at all.

Two hospitals in the capital adopted the procedure in the second year. The Royal Army adopted it in the third, which was the one that mattered, because the army did not care about theory and did care very much about the number of men it got back. By the fifth year there was a printed sheet nailed inside the door of every garrison infirmary in Lugunica, six pages long, and Venn's name was at the bottom of it, and hers was not.

She had one failure in that period and it galled her for the rest of her life.

She knew about the mould. She knew that somewhere in the enormous catalogue of things she had absorbed by osmosis in a world with electricity, there was a fact about a blue green mould on a dish and a circle where nothing grew, and that this fact had killed more disease than every physician who had ever lived.

She had no idea how to get at it.

She tried for two years. She grew mould on bread, on fruit, on broth, on meat, in the dark and in the light and in the cold. She had no way to see whether anything was happening, because the whole thing had to be judged on outcomes in living people and she was not going to test a poultice of unknown composition on a living person. She made extracts in water and in spirit. She made a paste that cleared an infected finger on a groom who volunteered, and then made what she believed was the identical paste six weeks later and put it on a carter's arm and the arm got very much worse and she stopped that afternoon and did not start again for eleven years.

She wrote all of it down. Every batch, every source, every result, including the carter, especially the carter, and she sealed the notebook and put it in the study and labelled it on the outside in her own hand:

Not ready. Do not use this. It is not consistent and I do not know why.

Somebody in the next century was going to open that book and know exactly where to start. That was the most she could do. It was not nearly enough, and she knew it was not nearly enough, and it was the first time she ran squarely into the wall that was going to define the rest of her life in this world.

She was not a genius. She had never been a genius. She was an ordinary young man from a country with libraries, holding a bucket he had filled by accident, and every single time she reached the bottom of the bucket there was nothing under it but the same two hands everybody else had.

The letter came in the winter.

She was in the kitchens, arguing with Bram about whether a thing could be called a stew if it had no root vegetables in it, and a footman came down the service stair at a speed that footmen do not use, and Thames came down behind him.

The royal seal. Her name on the outside in a clerk's hand.

She read it standing at the flour bin with the whole kitchen watching and the argument suspended.

It was three paragraphs. The first thanked her, in formal and slightly overwrought language, for services rendered to the health of the realm and to the Royal Army in particular. The second referred to the water works on the Astrea lands and gave the figure for the four villages in the dry August, which she had not known the Crown had, and which meant somebody had gone and counted.

The third conferred upon her, by grant and in perpetuity, the style and title of the Lady with the Lamp.

Theresia read that paragraph four times.

"Well?" said Bram.

"It is a soldiers' joke," she said.

"My lady?"

"It is a thing four hundred men in a garrison town started calling me because I would not go to bed." She folded the letter carefully along its existing creases. "And the Crown has now made it permanent and written it into the roll, and in three hundred years there will be children who are taught it in a schoolroom and who will assume it means something dignified."

She put the letter in her apron pocket.

"Where were we?" she said.

"Root vegetables," said Bram.

"Right. You are wrong about root vegetables."

But she went up to her room that night before dinner, and she shut the door, and she took the letter out and read the third paragraph once more.

The lady with the lamp.

She sat on the edge of the bed with it in both hands, and she thought about a ward at two in the morning, and a basin that had been topped up with water by a boy who was too frightened to report that the spirit had run out, and a soldier called Mattins with a crushed foot who had asked her to write to his sister because he could not write, and eleven things wrong with her own procedure that she had only ever found out because she had been standing in a dark room at an hour when nobody else was.

And she thought about a needle coming out of a cloth roll in a hot infirmary in July, and a boy called Tem who had walked back from the hayfield on his own legs, and a girl of eight with a notebook who had known and had said nothing.

She had been carrying a lamp around that ward for seven months. It had never once occurred to her that this was a thing anybody else could see.

That was the entire joke of her second life, laid out in a single line of a clerk's handwriting, and she was the only person in the world who would ever get it.
