Fog crawled along the Serpentine that afternoon, grey and cloying, as Phineas Whitlock climbed the stone steps of a Hampstead townhouse and knocked three times on the blackened oak door. He waited, collar turned against the chill, listening to the muffled bark of a small dog somewhere inside. The brass knocker was shaped like a fox, its snout worn smooth by a century of impatient hands. He resisted the urge to knock again. Patience, he reminded himself. She was always late. She was always worth waiting for.
Rosalind Penhaligon threw open the door before his knuckles could reach the wood a fourth time. She stood in a man's smoking jacket three sizes too large, her greying hair pinned up with what appeared to be a fountain pen. A cigarette smouldered between two fingers, leaving a trail of ash down her lapel.
"You took your bloody time," she said, in the warm rasp that had barked questions at dukes and frightened confessions out of crooked financiers. The dog, a terrier of indeterminate ambition, yapped at her heels. "Get in. I've made tea. It's terrible."
Whitlock stepped across the threshold into a hallway thick with the smell of old paper and pipe tobacco. The walls were papered in a pattern of faded roses, and every flat surface groaned beneath stacks of newsprint, letters, and leather-bound ledgers. He followed her into a parlour where the curtains had been drawn against the afternoon, and a single oil lamp burned low on a side table. The teapot was chipped, the cups mismatched. He accepted one.
"You've read my letter, then," he said.
"I've read your letter." Rosalind dropped into a wing chair, the terrier scrambling into her lap. "Cryptic as ever. 'Rosalind, I require your talents. Come at once. Bring nothing incriminating.' Very dramatic. Very you." She took a long pull on her cigarette. "So. What have you found?"
Whitlock set his cup down without drinking. From the inside pocket of his greatcoat he produced a small folio wrapped in brown paper and tied with twine. He placed it on the table between them like a man laying down a hand of cards.
"Last Tuesday," he said. "A woman came into the shop. She asked for first editions of Brontë. She bought nothing. She left this."
Rosalind's eyes narrowed. The cigarette paused halfway to her lips.
"She left it?"
"Tucked between the pages of a Chatterton. She must have palmed it when I turned to fetch the slipcase. By the time I noticed, she was gone."
"Describe her."
"Tall. Dark hair under a grey veil. Gloves. Spoke softly, with an accent I couldn't quite place. Eastern Counties, perhaps, or a very good imitation of one. She wore no wedding ring. Her boots were expensive but scuffed at the toes, as though she'd walked a long way."
Rosalind reached for the folio, then stopped. "It's not going to bite me, is it?"
"Open it."
She untied the twine. Inside lay a sheaf of papers, perhaps forty pages, covered in a dense, slanting hand. The ink was brown with age, the paper foxed and brittle at the edges. She lifted the first sheet to the lamp and squinted.
"Cipher," she said, almost to herself. "Plain as the nose on your face." She turned the page, then another. Her cigarette had burned down to the filter; she dropped it into a saucer piled with butts and lit another from the embers. "Run the shop blind, Whitlock. I taught you better than that. A woman palms a coded manuscript in your shop and you come running to me? You should have had her followed."
"I have considered that."
"And?"
"I would rather not involve the police. Not yet. Not until I understand what she wanted me to have."
Rosalind blew smoke toward the ceiling and considered him over the flame of her match. "You were always a terrible liar, Phineas. What aren't you telling me?"
He folded his hands. "The cipher. I have worked on it for four nights. I have made progress."
"Progress," she repeated.
"I have identified the period. The handwriting, the paper, the binding. Late sixteenth century. Elizabethan. Possibly Jacobean, but I think not." He paused, choosing his words. "There is a phrase that recurs. A name. I believe it is a proper noun. It appears in the margin of almost every page, sometimes crossed out, sometimes circled. The same seven letters."
"Seven letters." Rosalind set down her tea, untouched. "You don't mean."
"I do not know what I mean. That is why I am here."
She leaned forward, the terrier shifting in her lap. "Show me."
Whitlock produced a second item from his coat: a sheet of his own paper, covered in his neat, scholarly hand. Rows of letters. Tables. A diagram of overlapping circles. He laid it beside the folio.
"These are my working notes. I will not insult you by explaining my method. I have isolated what I believe to be a key phrase. The repetition of the name in the margin suggests it functions as the keyword for a polyalphabetic cipher. Once I had the period, I tested several candidates. The Baconian. The Argenson. The Porta cipher of 1564."
"And?"
"The cipher resists them all. The author knew his trade. He built in redundancies. He anticipated the kind of attack a competent opponent would mount."
Rosalind picked up the folio again, this time with the reverence of a woman who had once cracked a cipher that embarrassed the Vatican. She held the first page to the lamp and turned it slowly, her lips moving without sound. The terrier whined. She ignored it.
"The letter frequencies," she murmured. "Roughly even. Too even. He's padding. Padding with nonsense syllables to flatten the curve." She flipped a page. "Here. This flourish at the end of the third line. A tilde. He uses it as a separator, or a null." Another page. "These capital letters. They don't correspond to anything in the text. They spell something."
"What?"
"Patience, Whitlock." She reached for a pencil from the cluttered side table, found one with a broken tip, and began to make notes on the back of an envelope. "I taught you patience once. In Vienna. You remember Vienna?"
"I remember Vienna."
"Then you remember I take my time." She worked in silence for several minutes. The lamp guttered. The terrier fell asleep. Whitlock sat very still, the way he had learned to sit when Constance Beauchamp was working in the back room of the shop, when the particular hush of a woman bent over a difficult passage had settled into the air. He had not told Rosalind about Constance. He had not told Rosalind much of anything, these past ten years. He had not told anyone about the shopgirl with her quick tongue and her anxious eyes who copied manuscripts for him three afternoons a week and who, three nights ago, had looked up from the folio and said: Mr. Whitlock, this is a confession.
He did not know yet whether she was right. He suspected she was. He suspected Rosalind would tell him within the hour.
"I've got it," Rosalind said at last. She set down the pencil. Her cigarette had gone out. She did not notice.
"The cipher?"
"The cipher." She sat back, and her eyes, which had been distant, came back to him sharp and present. "It is a Vigenère variant, but a peculiar one. Not the standard tableau. A keyed tableau. The keyword determines not only the shift but the order of the alphabet itself."
"You're certain?"
"I am always certain, darling. It is my failing." She pulled the folio toward her and pointed to a passage near the bottom of the first page. "Here. The capital letters I mentioned. They are not capital letters at all. They are numerals in disguise. The Elizabethan conspirators used a similar trick. A, B, C stand for one, two, three. The letters are then used to index into the keyed alphabet." She tapped the page. "Your man knew his history. He wanted to be read, but only by someone who knew where to look."
Whitlock felt a prickle at the back of his neck. The lamp seemed to dim. The dog stirred in its sleep.
"Can you read it?"
"Can I read it? Phineas, darling. I have been decoding the private correspondence of cardinals and kings since before you sold your first incunabulum." She picked up her pencil again. "Give me an hour. Give me the night. I will give you a confession and a murder."
"And if there is more than one?"
She looked at him then, and the warmth went out of her voice. "Then I will give you more than one."
He nodded. He did not trust himself to speak. The fog pressed against the windows. Somewhere in the house, a clock ticked with the patience of a woman who had all the time in the world and intended to use it.
"Rosalind," he said, when he had found his voice again. "The woman who left the folio. She may come back to the shop. She may send someone."
"And you want me to watch."
"I want you to be careful."
She laughed, short and harsh, the laugh of a woman who had once had a price put on her head by a gentleman she could not name in print. "Careful is for other people, darling. Careful is for men who haven't spent forty years asking questions that ought to frighten them." She picked up her pencil and bent over the page. "Go home. Lock your shop. Tell no one. Come back at nine tomorrow morning, and bring decent tea. This stuff is an insult."
Whitlock rose. He felt the weight of the folio's absence at once, as though he had surrendered a limb. He had, he supposed, surrendered something. He crossed the room, and at the door he paused.
"Rosalind."
"Mm."
"Thank you."
"Don't thank me yet," she said, without looking up. "Thank me when I've told you what he's done. You may wish I hadn't."
The fog had not lifted. It pressed against the lamp in Whitlock's study with the weight of something alive, something that intended to stay. He stood at the window, one hand on the sill, the other hanging at his side, and watched the street below dissolve into the smeared suggestion of itself.
In the gaslight, the glass began to fog from his breath, and he stepped back before he could mark it. He did not want the shop boy to see a breath-print on the pane in the morning and wonder who had stood there at three in the morning, worrying.
He crossed to his desk. He did not light the lamp there; the gaslight from the street was enough for what he needed to do. He unlocked the drawer where he kept the folio's twin. The keys lay in a little leather wallet, and the wallet itself was a thing of which he was disproportionately proud. It had been made for him by a binder in Clerkenwell, some fifteen years before, from a single piece of calfskin the colour of weak tea.
The folio's twin was not a twin at all. It was a companion volume, an account book kept by the same hand, in the same cipher, over the same years. Whitlock had bought it from the estate of a baronet in Shropshire who had had no use for a dead relative's records. The baronet had called the volume dreary. Whitlock had called it treasure.
Now he sat with it in his lap, and he turned the pages, one by one, and he did not read the words. He knew better than to read the words. He knew the shape of them, the rhythm of them, the way they bunched at certain points and thinned at others, the way a particular sequence of characters occurred again and again at intervals that could not be coincidence. He knew the cipher itself; he had broken it ten years ago in an attic in Bloomsbury with a candle and a great deal of patience and a copy of Cardan's grid that he had made himself from bone.
What he was looking for tonight was something else.
He was looking for the last entry.
The companion volume's entries began, like the folios', on the first of January, 1871. They ended, also like the folios', on the thirteenth of February, 1879. Whitlock had always assumed that the deaths of the relevant parties were responsible. He had assumed, too, that there was nothing more to be found.
Tonight he wanted to be sure.
The last entry was dated, as he had known it would be, the thirteenth of February, 1879. It began in the middle of a sentence. That was unusual. Most of the entries began with a date, a name, a place. This one began: '...and if it should come to pass that this volume is read by anyone other than myself, then I am already beyond their reach, and the less said the better. But there are one or two things I should wish to set down, in case some future age is better equipped than our own.'
Whitlock read the words in the dark, his lips moving.
'I have kept these records because I could not bring myself to destroy them. I was not brave enough. I was not good enough. I did what I was told, and I was paid for it, and the money sits in a box under the floorboards of the house in Wigmore Street, where I shall not trouble to recover it. I name no names here because the names themselves are not the point. The point is the system. The point is that for ten years, while this city congratulated itself on its progress and its enlightenment, a man operated in its midst who took pleasure in the breaking of women, and who was never once called to account for it. I was one of those who might have called him to account. I was not alone. There were others. We were afraid. We were paid. We were, in our several ways, too small for the work.'
The next paragraph was shorter.
'The man is known to me, and to others, as the Cobalt. I do not write his real name because I am a coward. I am sorry.'
Whitlock looked up from the page. The gaslight on the street outside threw the shadow of an omnibus onto the wall, and the shadow passed like a thought. He turned back to the volume.
'If anyone is reading this, then the Cobalt is dead, or retired, or has become respectable. I do not believe any of these things. I believe he is alive. I believe he is comfortable. I believe that he gives money to hospitals and sits on boards and is spoken of in the newspapers as a man of substance. I do not know what to do with this belief. I have had it for twenty years. It has not changed.'
A page. Another page.
'For the avoidance of doubt: the meetings were held at a tavern in the parish of St. Marylebone, near the door of the church, which was kept by a man called, I will not write the name. The man called me, and others, to a private room above the tap, on the second floor, by appointment, in the small hours. We were shown in by a serving boy. We were given coffee that was not coffee. We were given our instructions. We were paid in cash, in used notes, and the notes were placed in our hands by the man himself. I have described him before, in the earlier volume, and I shall not repeat myself. He is not a young man. He is not an old man. He is the kind of man who passes through a room without leaving an impression on the air. I have known him for twenty years and I cannot describe his face.'
Whitlock set the volume down. He got up. He went to the window and stood there, with his forehead against the glass. The fog was so thick now that he could not see the lamp at the corner of Wigmore Place. He could not see the omnibus stand. He could not see anything at all.
The Cobalt. The Cobalt, who had been dead for forty years in his own imagining. The Cobalt, who had attended the lectures of the Society for the Promotion of Useful Knowledge. The Cobalt, whose name had been spoken, once, in a parlour in Hampstead, by a woman with a cane. The Cobalt, who had not been a man but a method, a system, a way of going on.
He had not been dead at all. He had been sleeping.
Whitlock went back to the desk. He turned to the entry in the folio that he had been studying when Rosalind had arrived. He read it again, and the words resolved themselves under his eyes with the cold precision of a chemical reaction.
'On the fourteenth of this month, in the upper room at the Seven Stars, the Cobalt will meet with the rest of us, and the matter of the dean's daughter will be settled. I am to bring the letters. The letters are to be read aloud. The letters are to be destroyed.'
The Seven Stars. The parish of St. Marylebone. A private room above the tap.
The companion volume had not named the tavern. The folio had named the tavern and the meeting and the matter to be settled.
Whitlock looked at the clock. It was half past three. He had been reading for an hour. He had not heard the shop boy leave. He had not heard the dog in the basement of the house next door begin to howl, which meant the dog was not howling. The world had gone very still.
He put the companion volume back in the drawer. He locked the drawer. He put the key in the wallet. He put the wallet in his inside pocket.
Then he took the folio from under the counter where he had hidden it before Rosalind arrived. He did not intend to leave it there. He intended to carry it with him, now, and to take it home, and to lock it in the strongbox in his bedroom, and to leave it there until Rosalind had finished her work and told him what she had found.
But he did not intend to carry it on the omnibus, even at half past three in the morning, even in a fog. He intended to walk.
He turned down the gas. He put on his coat. He took his hat from the stand in the hall. He went out the back way, through the yard, through the gate that opened into the mews. The mews were empty. The cobbles glistened under the lamps.
He turned into Wigmore Place. He turned into Henrietta Street. He crossed into Cavendish Square. The fog was so thick that the houses had dissolved into suggestions of themselves, into a faint illumination here and there where a window had been left unshuttered, into the smell of roasting coffee from a cafe that had not thought to close its kitchen. He turned south. He turned east. He came at last to a street he did not recognise, and he stopped, and he looked at the street sign, and the sign was so fogged over that he could not read it.
He had walked into the wrong part of town.
He was, he calculated, somewhere north of Marylebone High Street, somewhere east of Regent's Park, somewhere west of the great goods station at Paddington. He was not sure how he had got here. He had been walking for twenty minutes. The fog had been his guide.
He began to walk again, more carefully, and after five minutes he came to a crossing he did recognise. He turned south. He turned west. He walked for another ten minutes. He came at last to a street he did recognise, and he stopped, and he waited, and he listened, and the only sound he could hear was the sound of a woman laughing, somewhere in a room above a shop, the laughter of a woman who was not in the least afraid of the fog.
He turned into Welbeck Street. He turned into a passage he had not used in twenty years. He came out at the back of his own house.
He let himself in. He went up the stairs. He locked the folio in the strongbox. He sat on the bed. He took off his shoes. He put them on the floor beside the bed. He lay down.
He did not sleep.
At six o'clock the milk came. At seven the bread. At half past seven the postman, who brought a single letter, which was from his sister in Torquay, and which was about her husband's gout. At eight o'clock he got up, and dressed, and went downstairs, and made himself a cup of tea, and drank it standing at the kitchen window, and watched the fog begin at last to lift.
At nine o'clock he was back in the shop. He let himself in. He did not light the gas. He did not unlock the strongbox. He sat at his desk and waited.
At half past nine, Rosalind Penhaligon came in.
She was wearing a different hat. She was carrying a different bag. She was carrying, also, a small paper parcel that smelled of lard and vinegar, and which she set down on his desk before she sat down.
"I have brought the tea," she said. "I have also brought a pork pie, because I have not had breakfast, and you have not had breakfast, and we are going to need our strength."
She unwrapped the parcel. She cut the pie into halves. She gave him one half and kept the other. She poured the tea into two cups that she had brought with her, and she handed him one.
"Drink," she said. "Then I will tell you what I have found."
He drank.
She drank.
Then she set down her cup, and she looked at him, and she began.
"You've found something," Whitlock said. He did not ask it. He tasted the certainty of it in the back of his throat, metallic and sharp.
"Drink your tea," Penhaligon said. "And don't look at me like that. Like a dog that's been shown a rabbit hole."
He drank his tea. It was too hot. He drank it anyway.
She set her cup down with a decisive clatter against the saucer.
"The Fat Controller," she said. "That's what they call him at the Star and Garter, the ones who serve the private rooms. He's been coming for years, they say. Always late at night. Always with a different woman. But not the kind of woman you'd expect. Not opera singers. Not actresses."
"What kind?"
"Quiet ones," she said. "The kind that don't get looked at twice. The kind that leave no impression. He picks them up, he takes them somewhere, he brings them back before dawn. The chambermaids have seen it a dozen times. They think nothing of it. They think he's a respectable gentleman with peculiar tastes."
"But you do not."
"I do not," she said. "Because I went and looked at the register. The hotel register. And the name he signs is not always the same name. Sometimes it's Mr. Smith. Sometimes it's Mr. Jones. Sometimes it's Mr. Robinson. Last Tuesday it was Mr. Whitlock."
He set his cup down.
"He is using my name?"
"He is using your name," she said. "And he is doing it on the same nights that I am certain, from the cipher, that something is being moved. Moved and copied and sent somewhere. I cannot prove the connection yet. But I can feel it, Mr. Whitlock. I can feel it in my teeth."
He sat very still. The fog outside was thinning, but slowly, reluctantly, as though the city were unwilling to surrender its secrets to the morning.
"There is more," she said.
"Tell me."
"The lawyer," she said. "Mr. Quigley. I have made enquiries. He has a daughter. He has a daughter who is a nurse at St. Bart's. He has a daughter who, three weeks ago, asked her father for a loan of fifty pounds, which is a great deal of money for a nurse. And he gave it to her. And she has not been seen at the hospital since."
"Gone where?"
"Gone to the country, her father says. Gone to recover from a nervous complaint. But the father cannot tell me where. And the daughter has not written. And the father is frightened, Mr. Whitlock. The father is very frightened indeed."
She picked up her cup again and drank, and then she wiped her mouth with the back of her hand, which was a habit he found both vulgar and oddly endearing.
"So," she said. "We have a man with no face who uses your name. We have a lawyer whose daughter has vanished. We have a cipher that points to something being moved at night. And we have a bookshop, and a strongbox, and a folio that I very much hope you have not lost."
"I have not lost it."
"Good," she said. "Then we are agreed. We are going to find out who this man is. We are going to find out what he is moving. And we are going to find Miss Constance Beauchamp, if she can be found, before he finds her."
He looked at her. He looked at the pork pie, half eaten, on its greaseproof paper. He looked at his own hands, which were steady, which was remarkable given the circumstances.
"You are proposing," he said slowly, "that we investigate a conspiracy involving at least one Member of Parliament, possibly the government itself, possibly foreign powers, with no resources beyond a penny newspaper and a bookshop."
"That is what I am proposing," she said.
"And you believe we can succeed."
"I believe," she said, "that we have no choice. Because if we do not, then Miss Beauchamp dies. And if Miss Beauchamp dies, then the cipher dies with her. And if the cipher dies, then whatever truth it carries dies too. And I will not have that, Mr. Whitlock. I will not have it on my conscience."
She picked up her half of the pork pie and bit into it with a ferocity that was almost alarming.
He watched her chew. He waited until she had finished.
"Then we begin," he said, "with the lawyer's daughter."
She nodded.
They began.
---
The address she had obtained was in Clerkenwell, in a street of respectable but declining houses that had once belonged to solicitors and now belonged to nobody in particular. The door was painted a dull green. The bell did not work. He knocked.
They waited.
A long moment passed. Then the door opened a crack, and a face appeared, thin and wary, the face of a man in his sixties who had not slept well in some time.
"Mr. Quigley?" Whitlock said.
"Who's asking?"
"My name is Whitlock. I am a bookseller. I have reason to believe you may have had certain documents pass through your hands. Documents relating to a young woman. A Miss Constance Beauchamp."
The crack narrowed.
"I don't know what you're talking about," the man said.
"Mr. Quigley," Penhaligon said, stepping forward. "I am Rosalind Penhaligon, of the Evening Star. I am investigating the disappearance of Miss Beauchamp. I am also investigating certain irregularities in the handling of her late father's papers. I would very much like to speak with you inside, rather than have this conversation on the doorstep, where your neighbours may overhear."
The face went pale.
"You can't come in," he said.
"We can, actually," Penhaligon said. "We can, and we will. But it would be much pleasanter for everyone concerned if you simply invited us."
A long pause. Then the door opened, slowly, reluctantly, and they stepped into a narrow hallway that smelled of boiled cabbage and despair.
The sitting room was small and dark and immaculately tidy. There were photographs on the mantelpiece, all of the same young woman at various ages. A child. A girl in a school uniform. A young woman in a nurse's dress.
"Your daughter," Whitlock said.
"My daughter," the man said. He sat down in a chair that creaked beneath him. "Please. Sit down."
They sat.
"Tell us," Penhaligon said, "about Miss Beauchamp."
He told them.
He told them he had been approached, six weeks ago, by a man who had not given his name, who had paid him in cash, who had asked him to draw up a document. A document that purported to be a marriage settlement between Miss Constance Beauchamp, of Hampstead, and a gentleman whose name was to be left blank. A gentleman whose identity was not to be recorded. A gentleman who was, the man said, a person of importance.
"And you drew up this document," Whitlock said.
"I drew up this document," Quigley said. "I am a lawyer. I draw up documents. That is what I do."
"And Miss Beauchamp?"
"She came to my office. She came alone. She signed the document. She did not ask questions. She did not, I think, read it carefully. She seemed. Distracted. Frightened, perhaps. I do not know. I am a lawyer. I am not a mind reader."
"And then?"
"And then she left. And then, three days later, my daughter disappeared."
He stopped speaking. He put his hands in his lap and stared at them as though they belonged to someone else.
"They took her," he said. "They took her to make sure I keep quiet. They took her because I am the only witness, apart from Miss Beauchamp, and Miss Beauchamp is. Well. Miss Beauchamp is not in a position to speak, is she?"
"Where is she?" Penhaligon said. "Where have they taken her?"
"I don't know," he said. "I swear to you, I do not know. They sent me a letter. They sent me a letter that said if I spoke to anyone, if I went to the police, if I breathed a word of this to a living soul, then I would never see my daughter again. So I have not spoken. I have not gone to the police. I have sat in this house and waited."
"For what?"
"For news," he said. "For some word. For anything."
The room was very quiet. The clock on the mantelpiece ticked with mechanical indifference.
"We will find her," Penhaligon said. She said it with a conviction that surprised even Whitlock. "Mr. Whitlock and I will find your daughter, and we will find Miss Beauchamp, and we will see that justice is done."
Quigley looked at her. He looked at Whitlock. He looked, for a long moment, as though he might weep.
Then he opened a drawer of the desk beside him, and he took out an envelope, and he handed it to Penhaligon.
"This came this morning," he said. "No postmark. No stamp. It was simply pushed through the letter box while I was sleeping."
She took it. She opened it. She read what was inside.
Her face changed.
"Mr. Whitlock," she said.
He took the letter from her.
It was written in a hand he did not recognise. It was written in ink that was still wet enough to smear at the edges. It said:
She is at the place where the cipher began. She will not be there for long. Come alone. Come at dusk. Tell no one.
It was signed with a single initial.
G.
He read it twice. He read it a third time.
"G," he said.
"Yes," Penhaligon said. "G."
He folded the letter. He put it in his pocket.
"Then we know what we must do," he said.
"Do we?" she said.
"Yes," he said. "We must go to the place where the cipher began."
"And where is that?"
He looked at her.
"The bookshop," he said. "It began in the bookshop. It began with a folio I acquired six weeks ago from a country house sale in Shropshire. It began with a cipher I have been studying ever since. And if G means what I think G means."
He stopped.
"Then Constance Beauchamp," he said, "is in my shop."
The room was very quiet. The clock ticked. The fog, outside, had lifted at last, and the morning sun was beginning to creep, pale and tentative, through the curtains of the lawyer's sitting room.
Penhaligon set down her cup.
"Then we go," she said.
"Yes," he said. "We go."
He rose. She rose. The lawyer remained in his chair, small and broken, a man whose world had collapsed around him while he sat helpless in the middle of it.
"We will find her," Penhaligon said again. "You have my word."
The lawyer said nothing.
They left the house. They stepped into the street. The sun was thin and cold above the rooftops of Clerkenwell, and the air smelled of coal smoke and horse dung and the first, faint suggestion of spring.
Whitlock hailed a hansom. He gave the driver the address of his own shop.
The cab moved off.
Penhaligon sat beside him in silence for a long moment. Then she reached into her bag and took out a pencil and a piece of paper, and she began, very deliberately, to write.
"What are you writing?" he said.
"My story," she said. "The story I will publish when this is done. The story of a cipher, and a conspiracy, and a brave young woman who risked everything for the truth."
"You are very certain," he said, "that there will be a story to publish."
"There will be," she said. "There will be because I will make sure there is. Because that is what I do, Mr. Whitlock. That is what I have always done."
He looked at her. He looked at the determined set of her jaw. He looked at the pencil moving steadily across the paper.
He thought, not for the first time, that he had underestimated her.
He thought, not for the last time, that he would be wise not to do so again.
The cab turned into his street. The shop came into view, solid and familiar in the morning light, its windows dusty, its sign creaking gently in the breeze.
It looked, he thought, exactly as it always looked.
It looked, he thought, as though nothing had changed.
But something had changed.
Something was waiting inside.
He paid the driver. He stepped down. He offered Penhaligon his hand.
She took it.
Together, they walked towards the door.
