Dame Lwazi Mthembu did not walk into a room. She arrived in it, as weather does.

She came down the steps of the Orlei Rest House with both arms open and a laugh going ahead of her like a herald, a rolling, delighted contralto that turned the heads of the brass band, the schoolgirls, the soldiers on the gate and the stray dog asleep in the shade of a water tank. She was sixty, round and tall, in a robe of deep indigo printed with small gold fish, and a matching headwrap tied in a great architectural knot. Gold glinted in her ears and at her wrists. Behind her trotted an assistant in a pale linen suit, a thin earnest young man with two phones, one of which he held aloft on a stick, filming.

"There she is!" cried Dame Lwazi. "There she is, the girl of the quiet hand! Child, come here. Let me look at you."

Sefa had been standing in the shade of the Rest House gate for four minutes, pinned there by the sheer momentum of the arrival, with Teodor a stiff step behind her left shoulder and Captain Vosk on her right looking as though she had swallowed a lemon. She felt the crowd's eyes on her like warm hands. She did not move.

The Dame took both of her hands.

It was a warm, dry, enveloping grip, and it was very strong. The eyes that looked into hers were enormous and dark and merry, lined with laughter, so full of apparent delight that Sefa had the absurd sense of being the first person in a decade to have been properly seen.

"You are thinner than your mother," said Lwazi, "and your chin is better. Oh, don't look like that. I knew her well. We were very young. We got into frightful trouble." She leaned in. The scent of cloves and woodsmoke came with her. "I have so wanted to meet you. Will you take tea?"

It was a bright spring of kindness, and it struck Sefa that this was the second time today she had felt one open in front of her, and that on both occasions it had been very, very pleasant to stand in the sun.

"I'll take tea," she said. "With the captain."

"Of course with the captain!" Lwazi flung up a hand. "Captain Vosk, my dear, you look dreadful. You have not slept since March. Sit, sit. I have brought you cigarettes from the capital that taste of cardamom, and I know you are trying to give up, and I want to tempt you out of it purely for sport."

"I'd sooner be tempted by a fire exit," said Vosk.

The Dame threw back her head and roared.

The garden at the back of the Rest House was an old walled yard of dry fig trees and dusty roses, with a tiled fountain that had not run since the river went. Someone had set out a low table on a carpet and cushions around it, and on the table lay a tray of tea glasses, a dish of dates, a plate of small almond cakes in the shape of fish, and a laptop that was not being looked at. Lwazi arranged herself with a rustle on the biggest cushion. Vosk sat on the edge of a stone bench, as if she might leave. Teodor had been left at the garden door by the sergeant, to his visible displeasure.

Sefa lowered herself onto a cushion and took the glass she was handed. It was very hot and smelled of orange blossom.

"Now," said Dame Lwazi. "I am going to talk for ten minutes, and you will hate me for it, and then you may say whatever you like. The Concord has very old manners. A woman who wants something should offer it first." She raised a finger. "There is a saying in my mother's village. A bird that sings in a stranger's tree owes the tree a song."

"I haven't heard that one," said Vosk.

"You wouldn't. I made it up in the car." The Dame beamed. "It sounds correct, though, doesn't it? That's all a proverb is. A fib in a good coat."

They laughed. All three of them, a little, even Vosk. It slipped out of Sefa before she could stop it, and she felt the pleasant tug of the thing, the loosening, and set down her glass.

Here is what Dame Lwazi gave her in the next ten minutes. A pair of gloves of soft grey kid leather, which she said would hide the marks on her arm. A new handset, boxed, sealed, with a cheerful green logo, a Concord app called Cordline that she claimed no tower in the world could read. An introduction to a physician in Karabel who had treated, she said, a dozen cases of the bloom, and lost only four. A rumour, spoken in a lower voice, about a place far to the south called the Glass Flats, where there were people who had learned to live with it. A promise that Concord lawyers could keep Sefa out of the garrison's hands and the guild's. An offer of a house.

It was a very, very good performance. Sefa sat through it in silence, her fingers cold, her back straight, the notes pressed flat under her blouse. She watched the Dame's hands, her eyes, the long expressive sweep of her arms. She was waiting for it. She was waiting for the flat white paper to come out of the robe, for the pen to be set beside it, for the smiling voice to say *just here, my dear.*

It did not come.

Nothing was put in front of her. No page. No pen. No signature. The Dame was too clever to ask for anything at all.

*Whoever comes laughing, don't sign.*

She stopped listening to the words.

She began, instead, to listen to what was not being said. The pauses that came a second too soon. The name she had not yet used. Over the second glass of tea she realised that for ten minutes Lwazi had spoken of Sefa's arm, her rights, her health, her future, her mother, and had not once uttered the name of the dead man in the chapel.

"Dame Lwazi," she said.

"Mm?"

"You haven't asked me to do anything."

"I never ask anyone for anything." The Dame took a date. "It is a principle. I only make it easy for them to offer."

"And what would I offer?"

Lwazi chewed. She looked at Sefa across the almond fish, and the merriment went out of her face, not suddenly, but slowly, like the light going off a pan at dusk. What it left behind was more precise, and much older, and for the first time quite plain.

"A conversation," she said, "with a man you've already met."

Vosk, on the bench, went still.

"Ruben Achterberg," said Dame Lwazi, "was my courier. I should like you to know that. Not the Foreign Office's. Mine. I paid him a considerable sum, out of my own purse, to carry a certain object across three borders and put it in your hand." She sipped her tea. "He was forty-one years old. His wife has been waiting for him in Karabel for two years. I am told he has died of salt."

"He was carrying something for me."

"For you." Her eyes did not leave Sefa's. "A paper. It was the last thing your mother ever wrote. Her final writ, the one she never delivered. I kept it for her for nineteen years, because she asked me to, on the dawn she died. Not a good friend, to keep it so long. But I was afraid, child. I had good reason."

Sefa's heart was banging in her ears. She heard Vosk shift on the stone. She heard, from beyond the wall, the faint blare of the brass band starting up again.

"It was in his hand," she said. "The paper. It was a letter. It was from me."

The Dame's eyebrows rose a fraction. "Was it?"

"It said not to trust you."

There was a pause of about two seconds. It was the only time in the whole of the afternoon that Sefa saw Lwazi Mthembu without anything to say, and she understood that a great deal could be lost, in a small silence, by someone who was always talking.

"Ah," said Lwazi, softly. "Then you have already begun to remember. Good. I had hoped you might not be as helpless as they claim."

She set down her glass.

"Whatever you have been told, Sefa Tamarak, I will tell you one thing that is true. Ruben did not die by accident, and he did not die empty. What your mother wrote went into his mouth. He swallowed it, so no one could take it. Twenty-two hours ago I received word that he had reached the Quay alive. And now he is dead, and I would very much like to know," and here the beautiful voice dropped to something low and terrible and polite, "where the page went."

For a moment no one in the garden said anything. The dry fountain ticked in the heat. A fig leaf detached itself from a branch and turned over slowly on its way to the ground.

"Your bulletin," said Vosk.

The Dame turned her head.

"Person of interest. Do not detain. Report movements." The captain had not moved from her bench, but her voice had changed, all the dry black humour gone out of it, leaving only the flat edge of a soldier who has just worked out she was used. "It came across my desk eleven days ago under the Foreign Office seal. I took it for routine. It was yours."

"I borrowed a seal," said Lwazi, with a small apologetic hand. "A friend in the capital. I wanted you to watch him, Anahit, not stop him. A courier who is detained is a courier who is searched. I could not have your sergeants going through his mouth."

"You put a dead man on my border with a false flag on him."

"I put a living man on your border, my dear. The dead part was none of my doing."

Sefa looked from one to the other. The two women had said each other's names as if they were old, bruised acquaintances, and for a moment she saw the whole shape of the thing: a border held up by the courtesy of tired people who had decided, years ago, that it was easier to be on first-name terms with the thing that might ruin them.

"I don't know where it went," she said.

It came out clear and steady. The strange thing was that it was true. She had not seen a page in his mouth. She had seen only salt, white powder, packed in the tongue and the cheeks, curling when it was cracked, like handwriting. She thought of the pinch she had dissolved in the vestry, and the rain and the glass shelter and Haldis's ringed hand holding out the tea, and she thought, with a lurch like a missed stair: *what if the page and the salt were the same thing?*

"I'm sure you don't," said Lwazi, gently. She picked up the dish of dates and offered it. "But you will think about it. Sleep on it. The Concord has a room for you here, and a lock on the door that only opens from the inside. You would be safer than in that shop."

"Thank you. I'll stay where I am."

"Of course you will." The Dame laughed, softly, and it was almost the old laugh. "Your mother said you would."

Across the garden, in the arched doorway, Teodor Ilves-Nakamura gave a small, tight cough, the sort a man gives who has been listening for some time against his better judgement and has decided to be seen. Sefa rose. Her knees held. She bowed to the Dame exactly as far as courtesy required and not an inch further, and walked out across the dead roses with the cold new handset left behind on the cushion, untouched.

She was halfway to the gate before she thought of the chapel, and the vestry, and the chair that Ansgar had wedged against the door.

There was one man in Tuzlag, she realised, who was sitting alone with a corpse that three separate powers were willing to lie, bribe and borrow seals to get at. And she had left him with a biscuit.
