Chapter 1 of 20

The train exhaled a plume of grey steam against the sky, and Hollow Pines opened before Wren Avery like a watercolor left out in the rain. She pressed her palm flat against the cold window glass and watched the town assemble itself from fog and pine: a cluster of salt-weathered buildings hunched along the harbor, fishing boats tilting at their moorings, gulls carving slow circles above a single steeple. The platform was nearly empty. A porter dozed on a wooden bench. A woman in a navy coat hurried past, arms full of parcels, the heel of her boot clicking an impatient rhythm against the planks.

Wren gathered her satchel, the leather warm from resting against her hip through the long ride from the city. Inside, wrapped in a square of muslin, lay the journal she had carried for nine months, nine months since the funeral, nine months of turning its pages by lamplight and trying to make sense of the symbols her mentor had left behind. The brass clasp was cold when she touched it. She did not open the satchel. Not yet. The journal had waited this long. It could wait until she stood inside the shop her grandmother had left her, in a town she had not seen since she was small.

The step down onto the platform jarred her knees. The air carried brine and woodsmoke and something faintly sweet, damp leaves rotting in gutters. She tugged her coat tighter and followed the hand-painted sign toward the harbor road, her boots leaving clean prints on the damp boards.

The road curved downhill, flanked by leaning houses whose window boxes had gone to seed. Wrought-iron railings overlooked the water, green with salt. A cat watched her from a windowsill, amber eyes half-lidded, and Wren found herself speaking to it before she caught the habit. "Good morning." The cat yawned and turned away.

Hattie Brioche spotted her first.

The child burst from a side alley like a small, determined projectile, her braid swinging, her boots splashing through a puddle that had no business being as deep as it was. She skidded to a stop three feet from Wren and planted her fists on her hips, head tipped back, eyes wide and brown and utterly shameless.

"You're her," Hattie announced. "You're the granddaughter. You're the one who came on the train."

Wren blinked. "I... yes. I'm Wren."

"Hattie Brioche." The child stuck out a hand so abruptly that Wren had to fumble her satchel strap to free her own. The small fingers were cold and damp and gripped with surprising authority. "My sisters run the apothecary on Fisher Street. I'm not supposed to be down here. I'm supposed to be at school, but I saw the train come in and I knew it was you because nobody comes to Hollow Pines on the ten-fifteen anymore except people who mean to stay. Are you meaning to stay?"

"That is," Wren said carefully, "a great many questions in a row."

Hattie beamed. "I'm good at questions. I'm the youngest, so I have to be fast or I never get to ask any. Do you like cats? There's a cat that lives in the bookshop, but it only comes out when it rains, which is most days, so actually you probably saw it. Are you hungry? The bakery on the quay does good pasties, but Mrs. Bellweather puts too much pepper in hers, and if you don't tell her she puts too much pepper in yours next time too."

Wren let out a breath that was almost a laugh. "I haven't had breakfast."

"Then come on." Hattie seized her sleeve and began tugging her down the cobbled slope. "I'll show you where it is. The shop's on the way, you can see it from the corner. It looks like something out of a story. Your grandmother said so too. She said the bookshop looked like a story that hadn't decided how it ended yet."

The memory rose, unbidden: her grandmother's hands folded around a teacup, the steam curling past her face, the deep voice saying, Some books decide their own endings, little bird. The clever ones know when to wait.

Hattie chattered on, and Wren let the words wash over her, the bright current carrying her past the post office, past a chandler's shop whose windows were clouded with salt, past an awning under which two old men argued softly about the price of bait. The town had the feel of a place that had settled into its own quiet, the kind of quiet that was not empty but patient, waiting for someone to listen.

Then Hattie stopped so suddenly that Wren nearly walked into her.

"Here," the child said, with the gravity of a curator unveiling a masterpiece. "This is it."

The bookshop occupied a narrow building wedged between a chandler's store and a stone building whose windows were shuttered and dark. Three stories of grey stone, the windows streaked with rain, a wooden sign above the door so weathered that the gilt letters had nearly vanished. Wren could just make them out, carved into the grain: AVERY CO. RARE BOOKS AND CURIOSITIES.

And above the shop, set back behind a small gable, a cottage window looked out over the harbor. The same window she had pressed her face against as a child, when her grandmother had lifted her up to see the fishing boats coming home.

Her throat tightened. She had not expected that.

"It's very old," Hattie offered, watching her face. "Older than my sisters. Older than the apothecary. My oldest sister says it leans a little to the left, but the man who comes to check the foundations says it's just the ground settling. He says things settle here. He says the whole harbor is settling."

Wren looked at the child. "Is the door open?"

Hattie considered this with the seriousness of a magistrate. "I don't know. I've never been inside. My sisters say I can't go in because of the cat. They say the cat doesn't like people. But I think they just don't want me to lose anything in there, because once you go in you can't find your way out again, or at least not until the shop wants you to."

"That," Wren said, "sounds like something a sister would say to keep a person from wandering into trouble."

"Yes," Hattie agreed, "but it's still true."

Wren crossed the last few steps. The door was painted a deep, peeling green, the color of moss in shadow, and the brass handle was cold when she wrapped her fingers around it. She half expected it to stick. Instead, it turned with a soft, well-oiled click, and the door swung inward onto a smell so layered it almost had a texture: paper and dust and beeswax and something faintly chemical, like ink, and beneath that, the ghost of her grandmother's lavender.

She stepped across the threshold. Hattie, predictably, tried to follow.

Wren blocked the doorway with a gentle hand. "Why don't you go find that pasty? I'll be along in a bit."

Hattie narrowed her eyes, weighing the offer. "The one with the too much pepper?"

"If you insist."

A grin split the child's face. She turned and was gone, boots clattering back up the cobbles, her braid streaming behind her like a pennant.

The shop settled around Wren like a held breath.

It was smaller than she remembered, or perhaps she had been larger. The front room was a narrow canyon of shelves, every surface stacked with books, some upright, some flat, some balanced in precarious towers tied with twine. Light fell from the high windows in pale sheets, catching the dust that hung in the air, motes turning slowly, suspended. A glass counter stood near the back, the wood scarred with the rings of a thousand teacups, and behind it a brass cash box sat with its lid closed, patient as a tomb.

She moved between the shelves, trailing her fingers along the spines. A Compendium of Unusual Nautical Charts. The Gardener's Almanac, 1842. A Study of Mirrors, Their Histories and Uses. Some of the titles were familiar. Some were not. One shelf, near the back, had no titles at all, just unmarked leather spines in a row, and when she touched one she felt her fingertips come away faintly damp.

"Curious," she murmured, and somewhere above her, a board creaked.

She went still. The shop was silent except for the faint ticking of a clock she could not see and the soft, distant complaint of a gull outside the window. The board did not creak again. She told herself it was the building settling, the way the man in Hattie's story said things settled here.

She found the stairs behind a curtain of heavy green velvet. They were steep and narrow, the treads worn smooth in the center, and they groaned softly as she climbed. At the top, a short hallway, two doors. The first opened onto a small bedroom with a brass bed and a quilt patterned in faded roses. The second, the bathroom, smelled of lavender soap and something sharper, herbal. The third door, at the end, was the cottage.

It took her breath.

The room was larger than it had any right to be, the ceiling sloping under the eaves, a bank of windows looking out over the harbor. A stone fireplace occupied one wall, the grate cold, a pile of kindling stacked neatly in the iron cradle beside it. A kitchen table, scarred oak, stood near the windows, two chairs tucked under it. On the table, exactly as if someone had known she was coming, a teapot sat on a tray, and beside it a folded note, the paper cream-colored and heavy, her name written across the front in her grandmother's sloping hand.

Wren crossed the room. Her boots were loud on the floorboards, too loud, and she had the absurd conviction that the room was listening. She picked up the note. The paper was soft as cloth. The ink was the deep blue-black her grandmother had always used.

Little bird,

If you have come this far, you have read the cipher I left in the back of the journal, the one I told you was a lullaby. You were always too clever for lullabies. The answer is in the shop, but not on the shelves where you might look for it. The shop is older than I told you, and it remembers things I could not bring myself to write down. There is a room behind the room, and the door only opens when you are ready to see what is inside.

Do not trust the man who sends flowers. He has been patient for a long time, and patience is its own kind of violence.

I am sorry I could not say this in person. I am sorry for many things. The kettle is in the cupboard above the stove. Make yourself at home. You are home.

All my love, Grandmother

Wren read it twice. Then a third time. Her hands were steady, which surprised her, because her chest was not. The kettle was, in fact, in the cupboard above the stove, exactly where her grandmother had always kept it, and the stove was an ancient iron beast with a door that stuck when she tried it, and the tap over the sink coughed twice before surrendering a stream of rust-colored water that ran clear after a few seconds.

She boiled the kettle. She made tea. She carried the cup to the window and stood looking out at the harbor, where the fishing boats were returning in ones and twos, the men on deck small and dark against the grey water, their voices carrying faintly up to her. The tea was bitter. She drank it anyway.

The journal sat in her satchel. She did not open it. Not yet.

She was halfway through the cup when she heard, from somewhere below, the soft chime of the shop door.

A man's voice, low and unhurried, called up the stairwell: "Mrs. Avery? It's Calder. I saw the train come in and thought I might find you up there. I brought the key to the storeroom your grandmother asked me to keep. The one behind the second shelf of nautical charts."

The voice pulled Wren down the narrow staircase, her boots finding the familiar creaks on the second and seventh steps, the ones her grandmother had once sworn she would patch and never had. The shop was dim after the bright attic, the brass instruments in their cases catching the last of the daylight through the salt-hazed window. A man stood near the counter with his back to her, broad-shouldered, a flat leather satchel slung across him. He turned when she reached the bottom.

He was younger than she had expected. Dark hair, a scar that ran from his left temple into the hairline, the kind of tan that came from working outdoors and not from leisure. His eyes were the color of river mud and moved over her face with a steady, unhurried assessment that made her feel, briefly, like a letter being read.

"You must be the granddaughter," he said. "Calder Marsh. I worked the riverboats for your grandmother for a while, before I took the badge." He held out a key on a loop of waxed string. Brass, old, the teeth worn to soft nubs. "She asked me to hold this. Said you'd know what it was for."

Wren took it. The metal was warm from his pocket. "I don't, actually," she admitted. "She didn't mention any storeroom."

Something moved behind his expression, not quite a flinch. "She was a private woman," he said. "It happens."

He waited, and she understood he was waiting for her to ask him in, to offer tea, to do all the small social things her grandmother would have done without thinking. She did them because not doing them felt like a kind of betrayal.

"The kettle's on," Wren said. "If you've got a minute."

"I've got a few," he said, and followed her back up the creaking stairs.

She made him sit in the kitchen while she poured, and he accepted the cup with a nod that managed to be both polite and wary. The kitchen was small and bright with the last of the day's light, and her grandmother's dried herbs still hung in their bundles from the ceiling beam, stirring in the draft whenever anyone opened a door. The smell of them was the smell of every childhood afternoon Wren had spent in this house: thyme and rosemary and the sharper green note of bay.

"You came a long way for a key," Calder said.

"I came for the reading of the will," Wren said. "The key was a surprise."

"Will reading's tomorrow at the solicitor's. Posy Grieve's office, over by the chapel. Nine sharp. She don't like late." He sipped his tea. "Your grandmother spoke of you. Every time I brought the post she mentioned you. Said you had a head for puzzles. Said you were further than you sounded."

Wren felt her throat tighten, and was glad of the cup in her hands so she had somewhere to look that was not his face. "Further than I sounded," she repeated.

"Mm." He set his cup down. "She meant you had a life. One that didn't include coming back here. She worried about that. Whether she'd asked too much of you by staying."

"She never asked me for anything."

"No," Calder said quietly. "That's how she asked."

The clock on the mantel ticked. The wind moved through the eaves. Calder finished his tea and stood, and Wren walked him down to the door because that was what her grandmother would have done. At the threshold he paused and looked back up the stair, toward the room where the journal waited in her satchel.

"There's a man arrived on the afternoon coach," he said, with the careful casualness of someone reporting weather. "Name of Ezra Thatch. Says he's some kind of industrialist. Bought half the waterfront in the spring. Asking about the cipher. Asking about your grandmother. Asking about you, specifically, before he could have known you were coming."

Wren's hand found the doorframe. "Asking what, exactly?"

"Where you were. Whether you'd been in contact. Whether you'd inherited any of her papers." Calder's mouth thinned. "I told him I didn't know. I told him I'd pass along his card."

He held out a small rectangle of stiff cream paper. The name was embossed in a thin, elegant script: MR. EZRA THATCH. Beneath it, in smaller letters: THE HARBOR INVESTMENT COMPANY. An address Wren did not recognize, and a request, phrased as a courtesy, that she might find time to call on him at his rooms at the Silverleaf Inn at her earliest convenience.

"Be careful with that one," Calder said. "He smiles too much."

After he left, Wren locked the door and stood in the darkening shop for a long moment, turning the card over between her fingers. The paper was heavy and faintly fragrant, some expensive imported stock. On the back, in pencil, a single line in a hand she did not recognize: The cipher waits for no one.

She put the card in her pocket with the key, and climbed the stairs to change for the gathering.

The Silverleaf Inn squatted at the top of Harbor Hill like a fat grey cat that had eaten too many canaries. Wren had not been inside it since she was nine, when her grandmother had brought her for a birthday tea and the proprietor had produced a slice of cake so tall it required a structural assessment before eating. The place had not improved with age. The carpet in the entrance hall was the color of a bruise, and the wallpaper was the color of a different, older bruise, and the brass fittings had been polished to a shine that bordered on the aggressive.

The gathering was being held in the long room at the back, the one with the harbor view, and it was already half full when Wren arrived. She stood in the doorway for a moment, getting her bearings. The light was low and warm from the oil lamps on the mantel, and the air smelled of woodsmoke and something sweeter, the orange peel that the inn was fond of floating in its mulled wine. A string trio in the corner was playing something anachronistic and jaunty, the kind of music that pretended to be older than it was.

Posy Grieve spotted her first. The solicitor detached herself from a cluster of townspeople near the punch bowl and crossed the room with the brisk economy of a woman who had never knowingly wasted a step in her life. She was tall, silver-haired, dressed in a severe dark wool suit that looked as though it had been constructed rather than tailored. Her face was the kind that had been handsome once and was now handsome still, in the way of certain coastlines.

"Miss Avery," she said, and offered a hand that was firm and dry. "Welcome home. I am so very sorry about your grandmother."

"Thank you," Wren said, and meant it.

"I understand you'll be sorting through her effects. If you need anything sorted, catalogued, appraised, do let me know. I have a young woman, Nell Tarrant, who is excellent at that sort of thing, and I can have her at your disposal as early as Monday." Posy's eyes, pale and watchful, lingered a fraction too long on Wren's face. "Your grandmother left instructions. I have followed them, but there are some things I would prefer to discuss in person. Tomorrow morning, after the reading."

"Of course," Wren said.

"Good." Posy gave a small nod, as if sealing a small contract. "Now. There are people you must meet. Come."

She was led across the room in a gentle tow. A girl of perhaps ten was hanging back near the doorway to the kitchen, watching the adults with the bright, evaluative gaze of a magpie assessing a row of unattended nests. She was slight, dark-haired, with two uncombed braids and a dress that had seen better days and a few better weeks. Posy steered Wren toward her with the air of a woman presenting a particularly promising colt.

"This is Hattie Brioche," Posy said. "Youngest of the Brioche sisters. Her eldest sister runs the apothecary. The middle one runs the milliner's. Hattie runs everywhere and tells everyone about it."

Hattie beamed. "I heard that, Miss Grieve."

"You were meant to," Posy said, and moved on.

"It's lovely to meet you," Wren said. "I knew your grandmother too. She used to come into the shop for camphor and tell me about the gulls."

"She told me about you," Hattie said. "She said you were far away and that you were clever and that you had a cat named Postscript."

"I did," Wren said, surprised into a smile. "I mean, I do. He's staying with a neighbor."

"A cat," Hattie said, with the satisfaction of a fact confirmed. She glanced toward a cluster of older men by the window. "There's Sheriff Marsh. He's pretending not to see Mr. Thatch. They don't like each other very much."

"Hattie," Posy said, from three paces away, "perhaps Miss Avery would like to choose her own introductions."

"I'll just point, then," Hattie said, undeterred, and pointed.

Calder Marsh was indeed pretending not to see Ezra Thatch. He was standing with his back half-turned to the room, a glass of something amber in his hand, his attention fixed on the harbor view with the intensity of a man watching for a particular boat. Ezra Thatch was standing a few feet away, also with a glass, also watching the harbor, but with the looser posture of a man who was not watching for anything in particular and would not have minded being asked about it.

Thatch was the first to notice Wren. He turned, and the smile he produced was immediate, calibrated, and entirely without warmth. He was of medium height, immaculately dressed in a dark suit that caught the lamp light along its seams, his hair silver at the temples in a way that suggested either good tailoring or good lighting. His hands were soft. His eyes were not.

"Miss Avery," he said, crossing to her in a few unhurried strides. "I was hoping to make your acquaintance this evening. I am Ezra Thatch. I have the pleasure of funding the cipher expedition your grandmother organized."

"So I understand," Wren said.

"I sent round a card. I hope it found you." He took her hand before she could decide whether to offer it. His grip was correct and dry and held precisely long enough. "Your grandmother spoke of you constantly. She was very proud of your talents. She said you had an ear for patterns."

"She was generous."

"She was accurate, I think." Thatch's smile widened by exactly the amount required to suggest warmth without inviting it. "I have read her preliminary notes. Fascinating work. The cipher in question is unlike anything I have encountered. I have been pursuing it for some time, and I should very much like to discuss it with you. At your convenience, of course."

"Of course," Wren said.

Calder Marsh turned from his harbor vigil at last, and his expression when it settled on Thatch was the expression of a man who had just stepped on a nail and was trying to decide whether to acknowledge it. "Miss Avery," he said, with a nod. "I see you found the inn."

"I followed the lamps," Wren said.

"Good sense." He did not look at Thatch. "The mulled wine is drinkable. The canapes are ambitious. I'd recommend the wine."

"I'll have both, then," Thatch said, still smiling.

The silence that followed was the kind that could have been filled with a thrown punch, a pointed observation, or a sudden change in the weather, but none of those things happened. A waiter passed with a tray. Calder took a glass and moved away without a word of farewell, which was perhaps the loudest thing he could have said. Thatch watched him go with the satisfied look of a man who had just won a point in a game whose rules he had invented.

"Don't mind Calder," Thatch said, returning his full attention to Wren. "He is a loyal man, and loyal men are often suspicious of new faces. He carried the post for your grandmother for years, and I think he has not entirely forgiven himself for the delivery he failed to make."

"The delivery?" Wren said.

"The one that might have saved her life." Thatch sipped his wine. "But you did not hear it from me. And it is perhaps not a subject for a party."

He let that sit between them, then excused himself with the polite murmurs of a man who had delivered a parcel and was content to wait for it to be opened. Wren watched him cross the room, taking greetings from the innkeeper, bowing over Posy Grieve's hand, nodding to the string trio as though they had been hired to flatter him personally. She did not like him. She did not think she was meant to.

Hattie appeared at her elbow, breathing a little fast. "There's a woman over by the window says she knows your cat."

"I beg your pardon?"

"A woman. By the window. She says she knows your cat. Postscript. She says he bit her once, in a manner of speaking."

Wren followed Hattie's gaze. The woman by the window was small, dark-haired, dressed in a dress that looked as though it had been cut from a thundercloud and worn until the thunder was exhausted. She was watching Wren with an expression that was not quite a smile and not quite an invitation.

"Her name is Ottilie Penn," Hattie said, lowering her voice to a whisper that was audible to half the room. "She runs the lending library. She says she has a letter for you, but she won't say from whom."

Wren set her wine glass on the nearest tray and crossed the room. The lamps seemed to dim as she approached the window, or perhaps it was only that the woman standing in front of them had a way of pulling the light toward her without exactly asking for it.

"Miss Penn," Wren said.

"Miss Avery." Ottilie's voice was low and a little hoarse, the voice of a woman who had spent the afternoon shouting at children and the morning not apologizing for it. "I am sorry to approach you in such a place, but I was told you would be here, and I have something that belongs to you. Or that your grandmother intended for you. The distinction may matter."

She produced an envelope from the inside of her jacket. It was cream, like Thatch's card, but older, and there was no embossed name on the front. Only, in her grandmother's unmistakable hand, the single word Wren .

"She came by the library three weeks before she died," Ottilie said. "She asked me to hold this and to give it to you in person, the next time I saw you. She said it would be at a gathering of some kind, and that I would know which one." Ottilie's mouth thinned. "I told her that was a great deal to ask of a woman who does not attend gatherings. She said I would attend this one. She was right."

Wren took the envelope. It was heavier than she expected. She could feel, through the paper, the shape of something small and flat and hard.

"Thank you," Wren said.

"Don't thank me," Ottilie said. "Read it before you do anything else. Including, especially, anything that man in the dark suit suggests." She glanced across the room at Ezra Thatch, who was at that moment lifting a glass to his lips and looking directly at them. "He is not what he appears."

"Few people are," Wren said.

"True. But some are less what they appear than others." Ottilie gave a small nod, which seemed to include Wren and exclude the rest of the room, and withdrew into the crowd, where she was immediately invisible, as though she had been swallowed by the wallpaper she so closely resembled.

Wren stood by the window with the envelope in her hand and the harbor spread below her in the dusk. The fishing boats were coming in, their lamps already lit, their wakes silvering the dark water. Somewhere on the far side of the bay a foghorn sounded, low and slow, and the fog was already beginning to lift its pale shoulders over the breakwater.

She did not open the envelope. Not yet. She had learned, in the last twenty-four hours, that her grandmother had left a great many things in places she had not expected, and that patience was, perhaps, the only reliable form of respect.

She slipped the envelope into the inner pocket of her jacket, beside Thatch's card, and turned back to the party.

The string trio had moved on to something slower. Hattie Brioche was eating a canape with the deep satisfaction of a child who had been told she could not. Posy Grieve was talking to the innkeeper with the air of a woman negotiating a treaty. Calder Marsh was standing by the punch bowl, watching Wren, and his face, when it met hers across the room, held neither welcome nor warning, only the steady, unreadable patience of a man who had carried a great many parcels and intended to deliver this one himself, no matter the cost.

She lifted her glass to him, by way of acknowledgment. He lifted his in return.

Outside, the fog came in over the harbor like a slow breath, and the lamps of the fishing boats blinked one by one into the white.
