Mercy Is a Locked Door · Nowy Grzech

The first night, I tried the handle only to prove a point.

It turned. Of course it turned. Lucien Marrow does not lock doors. He told me so over a dinner I refused to eat, turning a glass of wine I refused to drink until the candlelight bled through it like something wounded. Locks are for people who expect to be left, he said. I don’t.

I had come to his house with a blade sewn into the hem of my coat and a name written on the back of my hand in ink that wouldn’t wash off. His name, or near enough: Marrow, of Blackmere, in the thin brown script the Chandlery uses for every contract it accepts. The ink is made from oak gall and iron and something the old women in the back room will not name, and it sinks into the skin like a promise. It comes off only one way. When the work is done, Mother Orla paints the letters with a caustic that smells of lemons and burnt hair, and you hold still while it eats the name, and afterward you have a pink new patch of skin that belongs to no one.

The back of my right hand had seven of those patches. I had stopped being able to tell where one ended and the next began.

The contract paid enough to buy a life somewhere warm, somewhere nobody had ever heard of me. More than that: it paid off the last of what my father owed the Chandlery when he sold them my years to settle his losses at cards. I was nineteen when he signed me over. I was twenty-seven on the night I came to Blackmere, and I had worked off eight years of his debt one pink patch of skin at a time. One more name, Orla said, tapping my knuckles with her ringed finger, and the ledger closes. One more, Vesper, and you can have your own name back.

I was very good at my work. I had never once been caught.

He didn’t catch me, either. He simply opened the door before I knocked.

Blackmere sits at the end of a causeway that floods twice a day, a long grey house built on a black spit of land between the salt marsh and the sea. I had walked the last mile in a fine cold rain with my collar up and my story ready: a governess bound for the next parish whose hired carriage had lost a wheel in the ruts. I had practiced the tremble in my voice. I had a torn hem and a muddy boot to show for it. I had climbed the steps and lifted my hand to the iron knocker, which was shaped like a woman’s fist, and before my knuckles touched it the door swung inward and there he stood.

The file had called him handsome in the way a clerk calls a knife sharp, which is to say accurately and without any understanding of what it means. He was tall, loose-limbed, thirty-four years old and dressed like a man who had forgotten for several years that anyone might look at him: shirtsleeves, no collar, a dark waistcoat unbuttoned. Black hair too long at the nape. A mouth that seemed to be enjoying a private joke. And his eyes, which were grey as the marsh behind me and very, very awake.

“You’ll be cold,” he said. “Come in. Mrs. Tully has put you in the blue room. It has the best view of the drive, in case anyone else comes.”

I opened my mouth to deliver the line about the carriage wheel. He was already walking away down the hall, leaving the door wide behind him, the rain blowing in over the flagstones.

I stood on the step for longer than I like to admit. Then I went in, because the work was inside, and I closed the door myself.

Dinner was served in a room with a table long enough to seat twenty and candles enough for forty. He sat at the head. I sat at his right hand, because he pulled out the chair for me and I could not think of a reason a stranded governess would refuse it. The food was simple and good. I did not touch it. A woman in my trade does not eat at a mark’s table, not in the first week, not ever if she can help it.

“Poison isn’t really my style,” he said, watching me not eat. “If I wanted you dead I’d have left you on the causeway. The tide comes in at nine.”

“I’m not hungry.”

“You walked four miles in the rain.”

“One mile.”

He smiled. I had given him something and we both knew it. “One mile, then. From the crossroads at Saltings, where the mail coach stops. There was no carriage, and no wheel, and you are not a governess, because governesses do not look at the windows of a room before they look at the people in it.” He turned his glass. “It’s all right. I’m not going to ask your name. I imagine you’ve got several.”

“Then why let me in?”

“Because it was raining.” He drank. “And because I’ve been expecting someone for a long time, and it seemed rude to make you knock.”

I should have killed him then. It would have been easy: the knife in my hem, the fork by my plate, the heavy candlestick at my elbow. The housekeeper had gone to bed. There was no one in that enormous house but the two of us and the sound of the sea. I have killed men in rooms with less cover and more witnesses. I sat and looked at the long line of his throat as he tipped his head back to drink, and I did not move, and I told myself it was because I needed to learn the house first. The exits. The servants. The routes to the causeway and the tide tables and whether there were dogs.

There were no dogs. There were, I learned that first night, no locks.

Not on the front door, which stood open until Mrs. Tully shut it at ten and never bolted it. Not on the cellar or the silver cupboard or the gun room. Every internal door in Blackmere had once had a lock; I could see the brass escutcheons, the neat keyholes. Every one of them had been drilled out, the mechanisms removed, the holes left open like empty eye sockets. You could put your finger through them and touch the air of the next room.

I tried my own handle only to prove a point, and it turned, and I stood in the blue room in my stockinged feet with the door ajar and felt something I had not felt in eight years at the Chandlery, which was exposed.

At the Chandlery they lock you in. Not cruelly, or not only cruelly. It is simply the way the house is built. The apprentices sleep in cells off a long corridor, and each cell has a door with a bolt on the outside, and each night Teodor Vane walks the corridor and draws the bolts one by one. Mercy is a locked door, he told us, the first week, when a girl from the docks cried to be let out. You’ll learn it for your work. The mark who can run is a mark who suffers. You shut the door, you do it clean, and that’s mercy. Remember it. Then he drew her bolt, and in the morning she was gone, and we did not ask where.

I remembered it. I had shut a great many doors.

I lay awake in the blue room with the dark pouring in through the gap and listened, and after midnight I heard him.

The house breathes at night. Old wood settling, rain fingering the windows, the long patient creak of him walking the hall outside my room. He never stops. He never tries the handle. He only walks, slow as a clock, from the head of the stairs to the tall window at the end of the corridor and back, until I fall asleep listening for him, and I hate, more than I have hated anything, that I have started to sleep better for it.

I kept a tally in those first days, the way I was taught. Mrs. Tully, the housekeeper: sixty, deaf in one ear, fond of him in a scolding, weary way. A boy called Tam who came across at low tide with the post and the milk and went back before the water rose. No guards. No guns loaded, though the gun room was full of them. The tides: low at three in the morning and three in the afternoon, near enough, creeping later each day. The east wing: shut up, the corridor to it blocked by a door that, uniquely in that house, did not open when I pushed it, because it had been nailed shut from the other side.

“Fire,” Mrs. Tully said, when I asked. She said it the way you would say drowning in a fishing village. “Ten years this Longnight. You’ll not go poking in there, miss. The floors are bad.”

I went poking in there anyway, on the third night, through a window from the outside, and the floors were bad. The wing was a black ribcage open to the sky. Rain had got into everything. Portraits had cooked on the walls until the faces ran. At the end of the upper corridor there was one door still standing in its frame, heavy oak charred to the grain, and on the floor before it lay a litter of old splinters where someone had once gone at it with an axe. Its lock was intact. Its keyhole was clogged with soot. I put my palm flat against the wood, and it was cold as a gravestone, and I did not know why my heart was going so hard.

“You could leave,” he said on the fourth morning, pouring coffee as if it were a courtesy and not a dare. “The gate is open. The car has keys in it. Nobody here will stop you.”

We were in the morning room, which faced the sea. The light came in white and merciless and showed me everything about him the candles had been kind to: the grey at his temples, the shadows under his eyes from all that walking. He had not slept, I thought. I wondered if he ever did.

“And the contract?” I said. There was no point pretending anymore. There had been no point since the doorstep.

“Fulfil it, then.” He set the cup in front of me and leaned close enough that I could see the old scar notched through his eyebrow, the one the file said a brother had given him. It was a short, ugly, puckered line, as if something toothed had been dragged across the bone. “I’m standing right here, darling. I’m not wearing anything under this shirt that could stop a knife.”

I did not move. He smiled like I’d confessed something.

“Who sent you?” he asked, straightening. “No. Don’t answer. You won’t know, will you? They never tell the hand what the mouth is saying.”

“How do you know what I know?”

“I don’t. I know what I’d do, if I were in the business of renting out people like you.” He went to the window. His back was to me. Every lesson I had ever learned lit up in me at once like a struck match: the back of the neck, the gap below the ribs, the soft place at the base of the skull. He stood with his hands in his pockets and watched the tide go out. “There’s a man at the Saltings inn who’s been asking the carter about you. Thin, grey, smells of tallow. He’s a friend of yours?”

Teodor. Of course. Orla never sends a blade out on a contract this size without a second knife somewhere behind it, to watch, and to finish, if the first one breaks.

“No,” I said. “He isn’t a friend.”

“Ah.” Lucien turned his head a little, so I could see the line of his cheek. “Then I’d say you have, what, until Longnight? That’s the date on the contract, I’d guess. My brother always did like an anniversary.”

The coffee had gone cold in my hands. “Your brother.”

“Casimir.” He said it gently, the way you touch a bruise to see if it still hurts. It did. I watched it hurt. “You’ve seen the east wing. You’ve seen the door. He’s the only man alive who hates that date more than I do, and the only one who stands to gain if I don’t live to see it.” He came back to the table and looked down at me, and his face was tired and oddly kind. “The gate’s open,” he said again. “Whatever you decide, I want you to know it’s open.”

He left the room. He left that door open, too.

I did not take the car. I did not walk out through the gate. I told myself I was staying because a contract abandoned is a death sentence at the Chandlery, and because Teodor was at the Saltings inn smelling of tallow, and because Longnight was seventeen days away and a professional does not rush. All of that was true. None of it was the reason.

On the seventh night I finally went to him.

Not with the blade. I told myself it was with the blade. I held it the whole way down the hall, bare feet on cold stone, the steel warm from my hand, until I found him sitting in the dark library with his back to the door. An open door. Always open.

The fire had burned down to a red eye in the grate. He was in a wing chair with a book face down on his knee and a glass on the floor beside him, and the room smelled of old leather and peat smoke and the salt that got into everything at Blackmere. Rain on the long windows. The sea somewhere below, turning over in its sleep.

“You’re shaking,” he said, without turning.

“It’s cold.”

“It isn’t.” He reached back, unhurried, and put his hand over mine, over the knife, and guided the point until it rested just beneath his jaw, where the pulse lives. “There. Now you know exactly where it is. Now you’ll never have to wonder.”

His heartbeat under the steel was so calm it made mine riot.

I stood behind his chair with my hand trapped under his. I could feel the rise and fall of him through the blade. I could feel the warmth of his fingers, the rough edge of a callus on his palm, the faint tremor that was not in him at all but in me. One push. I had done it a hundred times on the leather dummies in the Chandlery cellar, and seven times on men who deserved it, or whom someone had paid to say deserved it.

“Why?” I said. My voice came out wrong. “Why do you want this?”

“I don’t want it.” He tipped his head back against the chair, which pressed the point a hair deeper, and a bead of blood came up black in the firelight. I jerked the blade away before I could think. He let me. He let go of my hand. “I want to stop waiting for it. There’s a difference. For ten years I’ve walked these halls wondering which night he’d send someone. Which door they’d come through. I took the locks off so they’d never have to break anything to get to me. I told myself that was a kind of courage.” He laughed, low. “Mrs. Tully thinks it’s grief. The vicar thinks it’s madness. I think it was just very, very tiring.”

I came around the chair. I don’t know why. I wanted to see his face. He looked up at me, and there was a thin red line on his throat where I’d marked him, and his eyes were wet and entirely steady.

“Put the knife down,” he said softly.

“No.” Something in me flared, bright and furious. “You don’t get to tell me that. You don’t get to put my hand on your throat and take it away again. You don’t get to decide what I do with it.”

“You’re right,” he said at once. “I’m sorry. I don’t.”

The apology undid me more than the knife had. No one at the Chandlery had ever said it to me. No one had ever handed back a choice they’d taken, just like that, as if it had been mine to begin with.

I looked at the blade. I looked at him. Then I bent and set the knife on the side table, beside his glass, with the handle toward him, and I straightened, and I put my hand where the knife had been, over the pulse at his throat. It jumped under my fingers. Not so calm now.

“Is this the knife’s decision,” he asked, very quietly, “or yours?”

“Mine.”

“Then say what you want. I won’t guess. I’ve been guessed at my whole life.”

“I want to kiss you,” I said, and it was the truest sentence I had spoken aloud in eight years.

He didn’t move. He waited. He made me come the rest of the way, and so I did: I leaned down with my hand on his throat and my hair falling around both our faces, and I kissed Lucien Marrow in the dark of his burnt house, and he tasted of whisky and salt and the copper of his own blood where it had smeared at the corner of his mouth. He kissed me back slowly, as if he had all the time in the world and meant to spend it there. His hands stayed on the arms of the chair. I could feel what it cost him in the rigid line of his shoulders. When I finally drew back he was breathing hard, and so was I, and his knuckles were white on the leather.

“You can touch me,” I said.

“Not tonight.” His voice was rough. “Tonight you came down here to kill me and you kissed me instead. I’d like you to go to bed and wake up and still think it was a good idea. If you do, you know where I’ll be.”

“Walking the hall.”

“Walking the hall,” he agreed.

I took the knife with me when I went. He watched me go, and when I looked back from the doorway he had touched two fingers to the cut on his throat and was looking at the blood on them as if it were a letter from someone he loved.

The letter came four days later, folded inside a chandler’s bill for twelve pounds of beeswax that nobody at Blackmere had ordered. Tam brought it across at low tide with the milk. Mrs. Tully grumbled and left it on the hall table, and I took it up to the blue room and held it to the candle until the second writing came out brown between the lines of the first.

Vesper. Longnight stands. The client grows restless and will attend the settling in person, as is his right under the old terms. T. is at Saltings to assist. Do not make me send him in. The ledger closes on your hand or not at all. O.

Folded in with it, as the Chandlery always folds them, was the client’s token, a coin to prove the contract genuine: an old gold sovereign with a hole drilled through it, and stamped into the gold beside the king’s head, small and deliberate, a signet mark. A heron standing in reeds.

The same heron was carved over the fireplace in the library. It was cast into the iron fist of the door knocker. It was on the ruined portraits of the east wing, on a painted shield above a painted man’s head.

I went to find him. He was in the morning room with the tide tables spread across the desk, and when I put the coin down on them he looked at it for a long time without touching it.

“Well,” he said at last. “At least now we both know.”

“You knew already.”

“I guessed. Guessing is not the same as having it put on the table in front of you.” He picked up the coin and turned it over. “He’ll come himself. That’s what it means, isn’t it, attending the settling? He wants to watch.”

“It’s an old right. Most clients don’t use it.”

“Casimir will.” He put the coin down. His hand was not quite steady. “He’ll want to stand in the doorway.”

I sat on the edge of the desk. The window was full of grey water and grey sky. “Tell me,” I said. “All of it. I have a right to know what I was sent to finish.”

He was quiet so long I thought he wouldn’t. Then he began to talk, and he did not look at me once.

His father, Gideon Marrow, had been a man who believed that everything in his house belonged to him and that the proof of ownership was a key. He had kept the wine locked and the books locked and the boys, when they misbehaved, locked in the cellar in the dark. And he had kept his wife locked in her rooms in the east wing for eleven years, for her nerves, he told the parish, because she had twice tried to leave him and twice been brought back.

“I was twenty-four,” Lucien said. “Casimir was twenty-seven. We were grown men and we let it happen. That’s the part I can’t get round. We’d been so well trained that we let it go on. And then that winter I finally found the spine for it. I bought passage for her from Harwich. I was going to take her on Longnight, when the whole household was at the church. I told Casimir, because he was my brother and I thought he’d come.”

“He told your father.”

“He told our father. And our father went to church as planned, and gave Casimir the key to her door, and told him that if it was opened for any reason before he returned, he’d be cut off without a penny. Casimir had debts even then. He had debts before he could grow a beard.” Lucien’s thumb moved over the heron on the coin. “I don’t know how the fire started. A candle. A lamp knocked over. Her, maybe. She’d been in that room a long time. I was on the causeway with the trap when I saw the glow. By the time I got up the stairs the whole corridor was smoke, and Casimir was standing outside her door with the key in his fist.”

He touched the scar through his eyebrow.

“I asked him for it. Then I begged. Then I tried to take it, and he hit me with it closed in his hand, teeth out, and it opened my face to the bone. I couldn’t see for the blood. I went back down for the axe.” He breathed out. “It’s a very thick door. Our father had it made that way. By the time I’d got the key off Casimir, she wasn’t screaming anymore.”

I thought of the splinters on the floor before that door. The axe marks. The keyhole clogged with soot. I had put my hand on it and not known why my heart was going.

“Our father died two years later. He left the estate in trust, to pass on the tenth Longnight after the fire to whichever of his sons still kept Blackmere. That was his joke. His last lock. Casimir couldn’t stand to stay. I couldn’t stand to go. So I’ve kept it, and I’ve walked those halls every night listening for her, and Casimir has spent ten years drinking and gambling against an inheritance he can only have if I’m dead before the bells on Longnight.” He finally looked up. “And that’s who hired you. A coward with a key in his fist. I’m sorry. You deserved a better client.”

It was such a ridiculous thing to say that I laughed, and the laugh broke in the middle into something else, and I put my hand over my mouth.

“My name,” I said, when I could, “is Elin. Elin Sayer. My father sold my debt to the Chandlery when I was nineteen, to pay what he’d lost at cards, and they locked me in a cell every night for eight years and called me Vesper, and nobody has said my real name since.” I took my hand away. “I don’t know why I’m telling you.”

“Yes, you do,” Lucien said.

He stood. He came around the desk, and he stopped a yard away from me, close enough that I could smell the salt and smoke on him, and not one inch closer.

“Elin,” he said, as if he were testing whether a floor would hold. And then, lower, “Elin.”

I have been cut, burned, beaten with a leather strap in the Chandlery yard. None of it went through me the way my own name did in his mouth.

“Take me upstairs,” I said.

He didn’t move. “Say it again tomorrow, too.”

“I’ll say it every day if you want. I’m saying it now. I’m not afraid of you, Lucien. I’m not here for the contract. I’m not confused. I want you to take me upstairs and I want you to take me to bed.” I slid off the desk and closed the yard between us myself. “Is that clear enough for a man who’s been guessed at his whole life?”

His answer was his hand, lifting at last to the side of my face, his thumb tracing the line of my cheekbone as if he had been imagining the exact shape of it for eleven days. “Yes,” he said. “God, yes. That’s clear.”

His room was at the end of the corridor he walked every night, a plain high room with a bed too big for one man and a fire Mrs. Tully had laid and nobody had lit. He knelt to light it while I stood in the middle of the floor with my arms around myself, and I watched the flame catch and climb, and I watched the back of his neck, and for the first time in my life I did not measure the distance to it.

When he stood, he looked at the door. It stood half open to the dark hall, as every door in that house stood.

“Shall I close it?” he asked.

I thought of the bolts at the Chandlery sliding home one by one. I thought of the thick oak door at the end of the burnt wing.

“Leave it,” I said. “I want to know I could go.”

“You could.” He came to me. “At any point. For any reason or no reason. You say stop and I’ll stop, and I’ll walk the hall, and I won’t ask you why.”

“I know.” And I did. That was the terrible thing, the thing that made my throat ache. I knew it the way I knew the tide.

He undressed me slowly, as though every button were a question, and I answered each one by lifting my chin or turning my wrist or pressing closer. My coat with its hidden blade. My dress, the plain grey governess’s wool. The shift beneath, which he drew over my head with his knuckles barely grazing my ribs, and then I was standing in the firelight in nothing but my skin and the seven pale patches on the back of my hand, and he looked at me for a long moment without touching.

“Lucien.”

“I’m memorising,” he said, hoarse. “Give me a moment. I’ve been in a house full of ghosts for ten years.”

I pulled his shirt free of his trousers myself. I wanted to. I wanted my hands on him the way I had wanted almost nothing, and I spread them flat on his stomach and felt the muscles jump, felt the heat of him, the heavy knock of his heart when I slid my palms up over his chest. There were other scars. A white seam along his forearm where a burning beam had fallen on him. A dappled shine of old burn across one shoulder. I kissed that one. He made a sound as though I had struck him.

He lifted me onto the bed as if I weighed nothing and followed me down, and when his mouth found my throat I arched to meet it. He kissed his way down my body with a patience that bordered on cruelty: the hollow of my collarbone, the curve of my breast, the tight peak of my nipple, which he drew into his mouth until my fingers knotted in his hair and I heard myself say his name in a voice I did not recognise. His hand moved over my belly, lower, and stopped.

“Yes?” he said against my skin.

“Yes. Don’t stop asking. Don’t stop.”

He touched me as if he were learning a language. Slow at first, the flat of his fingers, then the tips, circling, listening to every hitch of my breath and following it. I had known pleasure before, the brief private kind, snatched in a locked cell. I had never known it given. I had never lain open under someone’s hands and been attended to, as if my body were a thing worth the whole of a man’s concentration. When he slid two fingers inside me I cried out, and he stilled, and I grabbed his wrist and held it there. “More,” I told him. “That’s a yes. Everything I say tonight is a yes unless I tell you otherwise.”

“Then tell me,” he breathed, and curled his fingers, and I stopped being able to tell him anything at all.

I came apart with my heel dug into the mattress and my hand clamped over my own mouth, because eight years of silence do not leave a body quickly, and he took my wrist gently and moved it away and kissed my palm. “No one’s listening,” he said. “No one but me. Let me hear you.”

So the second time, I let him.

When at last he rose over me, braced on his forearms, his hair falling in his eyes, he waited. Of course he waited. I reached down between us and guided him to me, and I watched his face as I did it, and it was the face of a man walking out of a burning building into the rain.

He pushed into me slowly, and the stretch of it, the fullness, drew a long, shaking breath out of both of us. Then he held still, forehead to mine, trembling with the effort. I wrapped my legs around him and pulled him deeper, all the way, until there was nothing between us, not a knife, not a name, not a contract written in gall ink.

We moved together like the sea against the causeway, slow and relentless, the fire throwing our shadow huge against the ceiling. He said my name into my mouth. He said it into my hair. When I rolled us, needing to be above him, needing to set the pace myself, he let me, and lay back with his hands on my hips and looked up at me as if I were the first dawn he had seen in a decade. I rode him until the ache in me became a single bright point and broke, and he followed me over with my name torn out of his chest, his arms locked around my back, holding on as though I were the only fixed thing left in the world.

Afterward we lay tangled in the wreck of his sheets, listening to the fire and the rain. The door was still open. The dark hall beyond it was just a hall.

“You didn’t walk tonight,” I said, much later.

His arm tightened around me. “No,” he said, sounding surprised. “No, I didn’t.”

Teodor found me in the churchyard at Saltings three days before Longnight, which is to say I let him find me there, because I wanted the meeting on ground with a wall at my back.

He was sitting on a flat tomb among the leaning stones, peeling an orange with a thumbnail, and he did not look up when I came through the lych gate. He had not changed. He never changed. The same long grey coat, the same thin grey face, the fingers pale and waxy as candlewicks from forty years of dipping them in the Chandlery vats. The smell of tallow came off him even in the wind.

“Vesper,” he said. “You’ve put on weight. It suits you. They must be feeding you.”

“What do you want?”

“What does anyone want? The ledger closed.” He split the orange and offered me half. I didn’t take it. “Orla’s patient. I’m less patient. Three weeks in the house and the mark’s still walking about, sleeping sound, buying you ribbons in the village. Oh, yes. The carter talks.” He ate a segment. “You smell of him, girl. I could smell it from the gate.”

I said nothing. Behind him, under a yew, there was a new-looking stone among the old ones: ISOBEL MARROW, WIFE OF AURELIAN. Someone kept the moss off it. Someone had left winter heather in a jar.

“Here’s how it goes,” Teodor said pleasantly. “Longnight, the client comes across on the evening tide to take his settling, as the old terms allow. You’ll have it done by the time the church bells finish, and you’ll do it in front of him, because he’s paid for the privilege. Then you come home and Orla burns the name off, and you get your own back, and we’ll say no more about ribbons.” He wiped his fingers on a handkerchief. “Or you don’t. And I go in and do the work myself, and then I do you, because a blade that breaks gets melted down. That’s the rule. It was always the rule.”

“The contract says Marrow, of Blackmere,” I said. “No Christian name. Why?”

He shrugged. “Client wrote it himself. Asked for the old form. Said a Marrow doesn’t like his given name in trade.” He looked at me properly for the first time, and his eyes were the colour of dishwater and utterly without malice, which had always been the worst thing about him. “Don’t do anything clever, Vesper. You remember what I taught you. Mercy is a locked door. Shut it on him quick, before he can run, and you’ll be doing him a kindness.”

“He doesn’t run,” I said. “He opens it.”

Teodor laughed, as if I had told a very old joke, and went back to his orange.

I walked back across the causeway with the tide coming in behind me, fast and silver, and it licked my boot heels the last hundred yards. Lucien was waiting on the steps. He had seen me from the window. He did not ask where I had been. He only took my cold hands in his and pressed them to his chest, inside his shirt, against his skin.

“Teodor,” I said. “Longnight. By the end of the bells. Casimir comes on the evening tide.”

“Yes.” He had known that too. “Come inside.”

We didn’t make it upstairs. We made it as far as the library, where the fire was high, and I shut the door behind us. It was the first door I had closed in that house since the night I arrived. It had no lock. It didn’t need one.

“I need,” I said, and stopped, because I didn’t know how to say it. My hands were shaking again, and not from cold. I had stood in a graveyard and been told I was a thing that could be melted down, and every part of me was howling to prove otherwise.

“Tell me,” Lucien said.

“I need to be the one who decides. Tonight. All of it. I need you to let me.”

He looked at me for a moment, and then he sat down in the wing chair, the same chair where I had held a knife to his throat, and laid his forearms along its arms and turned his palms up. “Then decide,” he said. “I’m yours to decide about. And if you want to stop, we stop. If I want to stop, I’ll tell you. Agreed?”

“Agreed.”

I undressed in front of him, slowly, with the firelight all over me, and I watched it wreck him. I watched his throat work and his fingers curl against the leather, and I did not let him touch me. I knelt between his knees and opened his shirt and put my mouth on him, his chest, the burned shoulder, the flat hard plane of his belly, and when I unfastened his trousers and freed him he was already hard and aching, and he said my name in a voice like tearing silk.

“Hands,” I said, when one lifted.

“Sorry.” He put it back. He was laughing and shaking at the same time. “God. Sorry.”

I took him in my hand and then in my mouth, and I learned him the way he had learned me, slowly, by every sound he made. The salt of him. The pulse of him against my tongue. The way his head fell back and his hips strained and he held them still anyway, because I had not said he could move, and that restraint, freely given, was the most intimate thing any man had ever offered me. When I rose and climbed into the chair and straddled his lap, he was breathing like a man who had run the causeway.

“Now you can touch me,” I said.

His hands came up to my hips like a prayer answered. I sank down onto him with my forehead pressed to his, inch by slow inch, and we both went still, full and filled, and his whole body shuddered under mine.

“Look at me,” I told him, and he did. I set the rhythm, slow and then less slow, the old chair creaking beneath us, the fire roaring, his hands spread on my back and his mouth on my breast and then my throat and then my mouth again. He let me take everything. He let me take him to the very edge and hold him there while I found my own, grinding down until the pleasure went through me in long helpless waves and I cried out against his temple, and only then, when I whispered now, yes, now, did he let go and pour himself into me with his arms locked around my waist and my name in his mouth like a thing he had been waiting ten years to say.

Afterward, still joined, still wrapped around each other in that ruined chair, he reached into the pocket of the coat draped over its back and pressed something into my palm. Metal, and paper. The keys to the car. A thick fold of banknotes.

I went cold. “Don’t.”

“I’m not telling you to go.” His voice was very quiet. “I’m not deciding anything. I’m making sure that if you choose to, you can, and nobody can say you had no way out. That’s all. That’s all it’s ever been.”

I closed my hand around the keys. “And you?”

“I’ll be here.” He brushed the hair back from my face. “But not waiting to die. I want you to know that. I’ve changed my mind about it.” His mouth crooked. “I find I’d like to see the spring.”

On Longnight I took the car.

I drove it out through the open gate at dusk, across the causeway with the water already fingering the stones, and I did not look back at the house, because he would be at the window and I could not afford his face. I left the car at Saltings under the church wall. Then I walked the long way round the marsh in the dark, a route I had learned in my second week, and came back to Blackmere the way I had first gone poking: through the black ribs of the east wing, past the thick oak door, over the bad floors.

The bells had begun across the water when I reached the library. The door stood open. Of course it did.

Casimir Marrow was by the fire. I would have known him anywhere: Lucien’s bones under a face gone soft and red with drink, Lucien’s height bowed into a stoop. Around his neck on a watch chain hung a heavy iron key, its teeth blackened. Teodor stood behind the wing chair with a blade laid flat against Lucien’s throat, exactly where I had once laid mine.

“Gone,” Casimir was saying, delighted. “You gave her the car. You always were soft, Lucie.”

“Not gone,” I said from the doorway.

Teodor didn’t move his knife. “Vesper. Good girl. Come and close the ledger. The client wants to see it.”

I walked into the room. My blade was in my hand. Lucien’s eyes found mine over Teodor’s arm, grey and steady and entirely unafraid, and I understood that he did not know which way I would turn, and that he had decided not to guess.

“Your choice,” he said softly. “It was always your choice.”

I put the point of my knife beneath his jaw, where the pulse lives. I felt it leap. Teodor lifted his own blade away to give me room, because he had trained me, and he trusted his training.

Then I turned on my heel, and the knife came with me, and I opened Teodor’s throat instead.

He had taught me that too. Quick, before they can run. He looked almost proud as he went down.

Casimir had a pistol out of his coat by then, and he fired it at his brother, and the ball tore through the wing of the chair and the meat of Lucien’s arm as Lucien threw himself sideways. I threw my knife. It was the best throw of my life. It took Casimir under the breastbone, and he sat down hard on the hearthrug with a look of great surprise, the key swinging on its chain.

Lucien knelt beside him with blood running down his sleeve. Casimir’s hand came up and closed around the key, teeth out, the way it must have closed ten years ago.

“I couldn’t,” he said. “He’d have taken everything. Lucie, I couldn’t open it.”

“I know,” said Lucien. “I know you couldn’t.”

The bells at Saltings rang the last stroke of Longnight across the flooded causeway, and Casimir Marrow, of Blackmere, died with his fist around the key.

I looked down at the back of my hand, at the thin brown letters. A Marrow doesn’t like his given name in trade, Teodor had said. The client had written the contract himself.

The magistrate called it housebreaking. Two armed men, the tide, a desperate brother with debts in three counties; Lucien told it plainly and bled on the man’s gloves, and nobody asked why a governess had been in the house.

Orla’s letter came in a bill for lamp wicks. The ink names Marrow, of Blackmere. The client’s own hand. A Marrow of Blackmere is dead by yours before the bells. The Chandlery keeps to its letter. The ledger is closed, Elin Sayer. Do not come back. Folded in with it was a small brown bottle that smelled of lemons and burnt hair.

I painted the letters myself, at the morning-room window, with the spring tide going out. Lucien held my other hand and did not look away while the caustic ate the name. Eight pale patches now. The last.

He threw the iron key into the sea off the end of the causeway. And in April a locksmith came across from Harwich, and fitted one new lock in the whole of Blackmere, on the door of the blue room, and Lucien put the only key into my palm and closed my fingers over it.

“So you know you can shut me out,” he said.

That night I opened my door and found him in the hall, not walking, only standing, waiting to be asked.

“Come in,” I said.

He came in, and I turned the key behind him. The bolt went home with a small, final sound, the first lock turned in that house in ten years, and I stood with my back to the door and the key warm in my fist, and it was not a cage, because I was the one holding it.

Then I undressed him by the window with the marsh silver under the moon, and he let me, and then he undressed me, asking with every button, and I answered every one. We went slowly, as if we had all the time in the world, because now we did. When he moved inside me I held his face in both hands and watched him, and he watched me, and neither of us looked toward the dark hall even once.

Mercy is a locked door, Teodor taught me. He was right about that. He was only ever wrong about which side of it you stand on, and who holds the key.
