The house on Ashwick Lane was two storeys of grey stone that had been standing long enough to have developed opinions about the people who passed below it. The roofline had gone slightly crooked in the last century, leaning a degree or two to the left with the settled confidence of something that had earned the right to lean. The neighbours had long since stopped noticing. The house was simply there, the way old things were simply there, without apology.
It had not always looked the way it looked now.
Henrietta noticed this every time they returned from a case, the particular pleasure of seeing what the house had become from the perspective of having been away from it. The climbing plant up the left wall had taken another foot of the drainpipe since autumn. The border along the front path was past its best for the season but still holding, the last of the late flowers doing what late flowers did, which was refuse to finish gracefully. The kitchen garden around the back she would check tomorrow. She could feel, even from the street, that something in it needed attention.
The house had looked nothing like this before she came. She had seen an engraving of it in an estate record once, from forty years prior: bare stone, bare earth, the windows dark in the way windows went dark when a person lived behind them who had no particular interest in how things appeared from outside. She had found that engraving useful. It confirmed what she had already suspected, which was that she was the first person in a very long time who had made this place look inhabited rather than merely occupied.
She was not sure Oz had noticed the difference. She was not sure he hadn't.
The carriage stopped. Oz got out first and stood on the pavement and looked at the house the way he looked at everything they returned to: a brief, comprehensive assessment, checking that the state of things matched his last record of them. Then he turned and offered his hand for the step down, which he always did and she always took, not because she needed it but because it was the kind of small courtesy that had solidified into habit and habits between them were their own kind of language.
She took his hand and stepped down and the door was already unlocked because it was always unlocked when they came back, which was something she had stopped questioning.
Inside, the house made its small sounds around them.
She went to the kitchen. He went through the ground floor in the way he always went through it on return: once, unhurried, each room briefly entered and briefly left, not checking anything specific, just reacquainting himself with the space. She had observed this ritual enough times to understand it without being able to explain it. She had written it in the private section: He walks the house when we return. As though confirming it is still here. I do not know if he knows he does it.
She put the kettle on.
He appeared in the kitchen doorway at the precise moment the kettle began to think about boiling, which was the kind of timing that was either coincidence or something else, and with Oz she had learned not to spend too much energy on the distinction.
He sat at the kitchen table. She made the tea and set his cup in front of him and sat across from him with hers, and the house settled around them and the street outside went about its business and neither of them said anything for a few minutes, which was not silence so much as the specific quality of quiet that existed between two people who had been moving very fast for ten days and had only just stopped.
She said: "Is there anything you want to do. Before the next case."
He looked at his cup. He considered the question with the full attention he brought to all questions, which meant he did not dismiss it and did not perform an answer.
"What is flowering," he said. "In the garden. This time of year."
She thought about it. "The last of the dahlias. Some of the asters, the dark ones along the back wall. The climbing rose is finished but the hips are good." She paused. "The hellebores will start in another few weeks if the cold comes properly."
He nodded slowly. "I want to see it," he said. "Before it finishes."
She looked at him across the table.
She said: "All right."
They took their tea into the garden.
The back garden was small and had more ambition than space, which was how she had always liked gardens. The beds were dense with the last things of the season, the dahlias going heavy-headed in the afternoon light, the asters holding their dark purple with the stubbornness of flowers that knew they were nearly done and had decided not to show it. The back wall had the climbing rose she had put in three years ago, bare now except for the hips, which were red and plentiful and caught the low sun in a way that justified the wall entirely.
Oz stood in the middle of it and looked at things.
He looked at them the way he looked at the bodies in Pembrook's surgery, the way he looked at the river at night: not with curiosity but with a kind of flat, precise attention. She had learned that this was simply how he looked at everything and not an indication of anything in particular. He brought his full attention to whatever was in front of him. Right now what was in front of him was the last dahlia of the season, deep red, slightly past its peak, still standing.
"You planted these," he said.
"Three years ago. The tubers came from a woman in Callum's Cross who grows them from seed. She is very particular about who she sells to." A pause. "She required a written letter explaining my intentions for the garden."
He looked at her.
"I wrote it," she said. "Two pages."
Something moved in his face. Not quite a smile. The thing that existed in the space where a smile would have been if he had been a different kind of person.
She turned to look at the wall.
"You never go into the garden," she said. It was not an accusation. Just an observation she had been sitting with for three years.
"I go now," he said.
She looked at him standing among the dahlias in his dark coat, entirely himself, entirely out of context, and thought something she would write later, in the private section, and did not say.
She said: "I know."
They stood in the garden until the light changed.
*****
The letter arrived in the evening.
Not by the common post. A private messenger, the kind employed by houses that found the common post insufficient to their purposes. He knocked precisely, waited without fidgeting, and handed her an envelope sealed with dark red wax before she had fully opened the door.
The seal was an architectural device she did not immediately recognise. A tower, old and narrow, with something wound around its base in a spiral. The kind of heraldic image that predated heraldry as decoration, chosen when symbols were still meant to describe something true.
She took it to her desk.
Oz was in his chair with a book open on his knee, which may or may not have been a book he was reading. He looked up when she sat down but did not ask.
She broke the seal and read.
The handwriting was precise and controlled, the kind produced by someone educated to a high standard who was now applying that standard under conditions that required more effort than usual. The diction was correct throughout and underneath the correctness something was pulled very tight.
To Mr. Oz and Dr. Henrietta Ashford,
I write to you from Rosemere, my family's estate in Thornshire, on a matter I find myself unable to address through any ordinary channel.
Three days ago, a member of my household was found dead at the base of the servants' stair. He was a young man, well-regarded, with no history of illness and no cause that Dr. Whitmore could establish. He is not the first. There have been two other incidents in the past six weeks, each without explanation, each preceded by a period of disturbance among the household staff that I can describe no more precisely than that.
I will not insult your intelligence by pretending I contacted you through ordinary recommendation. I was directed to you by someone who knew the nature of your work. I ask that you come to Rosemere at your earliest convenience. I am aware this is an unusual request from someone you do not know. I am also aware that unusual requests are, by your account, the only kind worth making.
Yours in some urgency,Eleanor VeldacreLady of Rosemere
Henrietta read it once. Then again. On the second reading she noted the specific phrasing: someone who knew the nature of your work. Not a friend. Not a name offered. Someone who directed her specifically and did not wish to be identified.
She looked up.
Oz had put the book down. He was watching her with the attention he brought to her face when her face was doing something worth reading.
She held out the letter.
He read it standing, which was how he read most things. He set it on the desk.
A silence.
"Thornshire," she said.
"Yes."
She looked at the letter. The seal with its tower and its wound spiral, the controlled handwriting, the phrase at your earliest convenience doing the work that immediately was too undignified to do for a noblewoman writing to people she did not know.
She picked up her pen. She opened the notebook to a fresh page and wrote the date and below it: Rosemere. Eleanor Veldacre. Thornshire.
She looked at what she had written.
Then she looked at him.
"When do we leave," she said.
He was already standing in the way that meant the answer.
"Morning," he said.
She looked at the window. The garden was dark now, the dahlias gone to shadow, the wall invisible. The last quiet they would have for some time, and it had been enough.
She closed the notebook.
