Chapter 27: The Devil’s Mercy

The morning after Lucien D’Arcy bled across their marriage bed, Blackwater House woke hungry.

Isolde felt it before she heard it—the subtle shift beneath the floorboards, the way the old mansion settled not with the ordinary groan of timber and stone, but with the listening patience of a thing that had been denied a meal. Dawn did not so much break over the estate as seep through it, gray and thin, sliding between the velvet curtains in Lucien’s room and touching the bruised hollows beneath his eyes.

He lay half propped against pillows gone damp with fever, bare to the waist beneath a sheet, the bandage at his ribs dark at one edge where blood had whispered through during the night. In sleep, he looked younger. Not innocent—never that. Lucien’s face had been shaped too early by violence and inheritance for innocence to settle there—but stripped of its cruel composure, he looked almost human. A man with black lashes resting against pale skin, lips parted on shallow breaths, one hand curled as if it still held a knife.

Isolde sat beside him in a chair dragged close enough that her knees nearly touched the bed frame. Sometime before dawn she had fallen asleep with one hand resting on his wrist, two fingers pressed to the steady pulse there. She woke to the sound of footsteps outside the door.

Not the soft, practiced steps of Mrs. Hallow.

Not the brisk, polished stride of Dr. Valez.

These steps hesitated. Then resumed. Then stopped again.

Isolde’s hand tightened on Lucien’s wrist. His pulse jumped beneath her fingers, but he did not wake.

Beyond the locked door, a floorboard sighed.

She stood without breathing. The room was chilled despite the banked fire. The storm had died in the small hours, leaving behind wet glass windows and a sky the color of old pewter. On the bedside table rested the objects of last night’s aftermath: a bowl of pink water, bloody linen curled like discarded tongues, a bottle of carbolic, Lucien’s signet ring, and the pistol he had insisted—half delirious, teeth gritted—remain within reach.

Isolde took the pistol.

It was heavier than she expected. Cold. Oiled. Horribly intimate in her hand.

The footsteps outside retreated one pace.

She crossed the room, bare feet silent against the rug, and stopped with her cheek nearly against the carved oak door. The key was turned in the lock on her side. Lucien had demanded it before unconsciousness dragged him under, his voice raw and broken.

Lock it. No one in unless you open it. No one.

At the time, she had thought it fever speaking.

Now, with the pistol raised in both hands and Blackwater House holding its breath around her, she was no longer certain.

“Who is there?” she asked.

A pause.

Then a woman’s voice, smooth as watered silk. “Only me, madam.”

Isolde recognized the voice. Celeste, the second housemaid with the pale blond hair and eyes like chipped ice. Celeste who curtsied too deeply, listened too long, and had once lied about a key with such polished innocence that Isolde had almost admired her.

“Only you doing what?”

“Mrs. Hallow sent me with hot water.”

Isolde glanced toward the dressing table. A full ewer sat there already, steam long vanished but the porcelain still wet at the lip.

“Set it outside.”

Another pause. A tiny scrape, as if a tray had shifted from one hand to the other.

“Mrs. Hallow said I was to change the linens, madam.”

“Then Mrs. Hallow may come herself.”

“She is occupied downstairs.”

“Then the linens may remain bloody.”

Silence pressed to the other side of the door. Isolde imagined Celeste standing there, face blank, eyes bright. How many servants knew Lucien was too weak to rise? How many had counted the hours since his last order had cracked through the halls? How many had waited for the beast of Blackwater to stumble?

“Madam,” Celeste said softly, “the master will be displeased if his room is left in such a state.”

Isolde smiled without warmth. “The master is currently unconscious. If he wakes displeased, I shall make certain to tell him you were concerned.”

The tray rattled. Just once.

“Very good, madam.”

The footsteps withdrew. This time, they did not hesitate.

Isolde remained at the door long after they faded, pistol still raised. Only when Lucien stirred behind her did she lower it.

His lashes fluttered. For an instant his eyes opened, unfocused and black with fever. They moved over her, the weapon, the locked door.

“Did you shoot someone?” he rasped.

“Not yet.”

A ghost of amusement touched his mouth. It vanished under pain. “Ambitious little bride.”

“Go back to sleep.”

“Don’t let them—” His breath caught. His hand jerked toward his ribs and stopped midway, fingers clawing at the sheet.

Isolde was at his side at once, setting the pistol down to press him back by the shoulder. His skin burned under her palm. “Don’t move.”

His gaze snagged on her face with sudden, savage clarity. “Don’t let them smell weakness.”

The words were ugly. Ridiculous. A fevered lord of a decaying house speaking as if his servants were wolves circling the carcass.

Then the house creaked.

Somewhere below, a door slammed.

Lucien’s hand closed around her wrist with surprising force. “Isolde.”

Her name sounded different from his mouth when he could not weaponize it. Rougher. Almost stripped bare.

“I heard you,” she said.

“No.” His fingers dug into her skin. “You don’t.”

He tried to rise. The effort drained what little color fever had left in his face. Isolde pushed him down again, harder this time.

“You will tear the stitches.”

“Hallow,” he said through clenched teeth. “Bring Hallow. Only Hallow. Bram if you must. No one from the east wing. No one with a silver pin. Don’t sign anything. Don’t drink anything you didn’t pour yourself. If Merrick comes—”

His voice broke on a breath that was almost a groan.

Isolde leaned closer. “If Merrick comes, what?”

Lucien’s pupils swallowed the thin ring of gray around them. “Don’t let him in the chapel.”

“What is in the chapel?”

But he was already slipping. His grip loosened. His eyes closed. One more breath scraped through him.

“Mercy,” he murmured.

The word chilled her more deeply than any threat.

By eight o’clock, the house had begun testing her.

Mrs. Hallow arrived only after Isolde sent Bram with a message written in Lucien’s black ink and sealed with his ring. The old housekeeper entered carrying a tray of fresh linen and boiled instruments, her gray hair pinned with its usual severity, her keys swinging at her waist like a jailer’s rosary. Her eyes went first to Lucien, then to the pistol on the bedside table, then to Isolde.

“You’ve barred the door.”

“Lucien told me to.”

“Good.”

It was not approval. It was confirmation.

Mrs. Hallow crossed to the bed and bent over Lucien with the brusque tenderness of someone who had bandaged him many times and never forgiven the world for making it necessary. She peeled back the edge of the dressing. Her mouth thinned.

“Fever’s up.”

“Dr. Valez said it might be.”

“Dr. Valez left before sunrise because someone cut the telephone line to the north gate.”

Isolde went very still. “What?”

“The motorcar would not start. Bram found sugar in the fuel. The doctor took the lower path on foot with two stable hands and a pistol. He said he would return by evening if the road hadn’t washed out.”

“And if it has?”

Mrs. Hallow looked at her. “Then we keep him alive until it hasn’t.”

Outside the windows, gulls screamed over the cliffs. Below, the sea hammered the rocks with dull, deliberate blows.

Isolde looked down at Lucien. His face was turned slightly toward her, dark hair damp at his temple. He had thrown himself between her body and a blade with no hesitation. He had killed for her. Bled for her. Then, in fever, apologized for a sin he still refused to name.

She hated him.

She wanted him to open his eyes.

She wanted answers. She wanted the truth laid bare between them like the corpse of last night’s intruder, no longer able to move in shadows.

She wanted him alive enough to suffer for it.

“Tell me what to do,” Isolde said.

Mrs. Hallow’s gaze sharpened. “Do you mean that?”

“I said it.”

“Saying and meaning are different arts in this house.”

“Then teach me the one that keeps him breathing.”

For the first time since Isolde had come to Blackwater House, something like reluctant respect moved through the housekeeper’s face.

“Very well,” Mrs. Hallow said. “You will not leave him alone. You will not eat from any tray brought by Celeste, Moran, or anyone who claims I sent them unless I am standing beside them. You will keep that pistol loaded. You will answer no letters. You will sign no papers. And if you hear bells from the chapel, you will wake him if you have to slap him bloody.”

Isolde stared. “Chapel bells?”

Mrs. Hallow returned to cleaning the wound. “Blackwater has many customs.”

“Blackwater has many crimes dressed as customs.”

“Aye.” The old woman’s voice went flat. “And many graves beneath them.”

Before Isolde could demand more, a sharp knock struck the door.

Not hesitant this time. Authoritative.

Mrs. Hallow froze with bloodied gauze in hand.

“Who?” Isolde called.

“Mr. Gideon Merrick for Mr. D’Arcy.”

The name slid under the door like smoke.

Isolde had met Gideon Merrick only twice: once at the wedding reception, where he had kissed her gloved hand too slowly and called Lucien fortunate with the tone of a man watching a noose being tied; and once in the corridor outside the west archive, where he had emerged from a locked room with no key in sight. He was Lucien’s cousin by some twisted branch of the D’Arcy bloodline, legal counsel to the shipping trust, and possessed of the kind of handsome face that had never needed honesty to be believed.

Lucien had said, If Merrick comes—don’t let him in the chapel.

Apparently, the devil had punctual habits.

Mrs. Hallow’s eyes flicked to Isolde. A question. A warning.

Isolde wiped her damp palms on her skirt and took up the pistol again, though she kept it low, hidden in the folds of her robe.

She opened the door only as far as the chain allowed.

Gideon Merrick stood outside in a charcoal suit cut with predatory precision, rain flecking the shoulders of his overcoat. He held his hat in one hand. A thin silver pin pierced his tie—the D’Arcy crest, a black cormorant with wings spread over a wave.

No one with a silver pin.

His eyes, pale green and amused, moved over the chain.

“Mrs. D’Arcy,” he said. “How dramatic.”

“Mr. Merrick. How early.”

His smile deepened. “Concern does not keep civilized hours.”

“Nor do vultures.”

For half a second, the smile held too still. Then he laughed softly. “Lucien has been a terrible influence.”

“He has had competition.”

Merrick leaned slightly, as if trying to see past her. Isolde shifted into the gap.

“I heard there was an incident,” he said.

“Did you?”

“Blackwater is not known for discretion when blood is spilled.”

Behind her, Mrs. Hallow continued working with the silence of a blade being sharpened.

“My husband is resting.”

“Then I shall be brief. There are urgent matters requiring his signature. The board has convened a private session regarding last night’s disturbance and the compromised cargo records. If Lucien is incapacitated, we must establish temporary authority.”

“Temporary authority.” Isolde tasted the words. They had the metallic flavor of a trap.

“A formality.” Merrick produced a leather folder from inside his coat. “Given your position as his wife, your signature could allow me to act on his behalf until he recovers.”

Isolde smiled.

Lucien, she thought, would have made the expression cruel. Hers came out colder.

“How generous of you to relieve me of power I did not know I possessed.”

Merrick’s gaze sharpened. “Blackwater is not merely a house, Mrs. D’Arcy. It is a machine. If one gear stops, the rest grind themselves to pieces.”

“And you are here with oil.”

“I am here with experience.”

“You are here with papers while my husband has a fever and a knife wound.”

He lowered his voice. “Your husband has spent years cultivating enemies. Some of us have spent equal time preventing those enemies from tearing open the doors. Whatever game you think you are playing, I advise you to understand the board will not wait for romance.”

The word struck like an insult.

Romance.

As if what lay behind her was something soft. As if Lucien were not burning through clean linen because someone had tried to cut her open in his house. As if the night had not been full of blood, teeth, and whispered apologies.

“Leave the papers,” she said.

“I’m afraid they require witness.”

“Then you may witness me not signing them.”

Merrick’s expression cooled. “Lucien has not told you enough to make enemies wisely.”

“No,” Isolde said. “But he has told me enough to recognize one impatiently.”

His eyes flickered.

There it was—a small break in the polish. Not anger. Not surprise.

Calculation.

He inclined his head. “I see.”

“Do you?”

“I see that his fever has not robbed him of his favorite pastime.”

“Which is?”

“Turning frightened women into weapons and pretending that is the same as keeping them safe.”

Isolde’s fingers tightened around the pistol grip.

Merrick’s gaze dipped, just barely. He knew.

Of course he knew.

“Careful, Mrs. D’Arcy,” he murmured. “Guns are simple instruments. Houses like this are not.”

“Neither am I.”

For the first time, Gideon Merrick looked at her as if she were not an inconvenience but a door he had found locked.

“No,” he said. “I am beginning to suspect you are not.”

He placed the leather folder on the floor just beyond the threshold and stepped back.

“Give Lucien my devotion.”

“I will give him your timing.”

His smile returned, faint and poisonous. “Do. He will appreciate the difference.”

He turned and walked away, silver pin catching the weak morning light like a sliver of bone.

Isolde shut the door. Latched it. Locked it. Then she stood with her forehead against the wood and forced herself to breathe.

Mrs. Hallow spoke behind her. “You did well.”

“Did I?”

“You did not open the door.”

“The standard for triumph in this house is appallingly low.”

“The standard for survival usually is.”

Isolde looked at the leather folder lying outside the door through the narrow gap beneath it, a dark tongue waiting to be pulled in.

“Should I take it?”

“No.”

“Why?”

“Because if it contains poison powder, a needle mechanism, or a legal clause that makes you complicit in treason, I’d rather it remain in the hall until Bram can fetch tongs.”

Isolde turned slowly. “That was not comforting.”

Mrs. Hallow tied a fresh bandage around Lucien’s ribs. “It was not meant to comfort. It was meant to instruct.”

The house gave her no time to recover.

By ten, the kitchen had erupted into a mutiny disguised as shortages.

“No coffee?” Isolde repeated.

Cook, a broad woman named Elspeth whose arms looked capable of kneading bread or strangling spies with equal efficiency, stood before the pantry shelves with flour on her cheek and fury in her eyes.

“Gone, madam.”

“Coffee does not simply vanish.”

“Nor does brandy, quinine, lamp oil, or six jars of preserved lemons, yet here we are in a world of miracles.”

Isolde stared at the shelves. They were not empty. That would have been too obvious. They had been curated. The visible stores remained—potatoes, onions, sacks of oats, barrels of salted fish. But the useful things, the things needed for fever, stamina, sterilization, light—those had been removed.

“Who has access?” Isolde asked.

Elspeth snorted. “Who doesn’t, when the master is bleeding upstairs and half the staff suddenly remembers errands?”

The kitchen smelled of yeast, damp wool, and resentment. Servants moved more slowly than usual, their glances sliding toward Isolde and away. She felt the shift in them. Not open defiance. Not yet. Something worse—the weighing of her. Lucien’s bride. Vale’s ruined daughter. Pretty enough in the papers. Proud enough in the chapel. But untested in the engine room of Blackwater House.

A scullery boy dropped a pan.

The crash cracked through the kitchen.

Every head turned to Isolde.

There it was. The invitation.

Would she flinch? Snap? Call for Lucien like a frightened wife?

Isolde looked at the boy. He was no more than fourteen, red-haired, freckled, eyes wide with either fear or performance.

“Pick it up,” she said.

He scrambled to obey.

She turned back to Elspeth. “Find me vinegar, spirits, honey, any tea with bark or willow, and clean cloth. Lock whatever remains. If you lack a key, break the pantry latch and send the bill to my husband’s enemies.”

Elspeth’s brows rose.

“And if anyone removes food or medicine from this kitchen without your approval,” Isolde continued, louder now, “you will give me their name.”

A footman near the hearth smirked. Young, dark-haired, handsome in the careless way of men who had been rewarded for it by housemaids and widows. Moran, she remembered. One of the names Mrs. Hallow had given.

“And what will you do with names, madam?” he asked.

The kitchen stilled.

Isolde turned toward him.

Moran’s smirk widened a fraction. He held a basket of kindling against his hip. His sleeves were rolled, revealing strong forearms. He had likely charmed half the household and bullied the other half. He looked at her as if she were lace mistaken for chainmail.

“That depends,” Isolde said. “On whether I can still use their bodies for labor.”

Elspeth choked on a laugh and turned it into a cough.

Moran’s smirk faltered.

Isolde stepped closer. “You have something to say?”

“Only that the house runs certain ways, madam.”

“Then it can run differently.”

“With respect, you’ve been here a month.”

“With equal respect, you have chosen an unfortunate morning to teach me arithmetic.”

His jaw tightened. “Master D’Arcy—”

“Is upstairs with twelve stitches in his side because someone entered this house with a knife.” Isolde let the words fall clean and hard. “Until he stands again, I speak for him.”

Moran looked around the kitchen, inviting witnesses to his courage. “Does he know that?”

Isolde smiled.

Not kindly.

“He bled on me. I consider it a written appointment.”

This time Elspeth did laugh, sharp and delighted before she buried it in her apron.

Color climbed Moran’s neck.

“Take the kindling to the sickroom hearth,” Isolde said. “Then report to Mrs. Hallow. If she does not need you, scrub the east corridor. If I see you standing idle again, I will assume you are listening for the wrong people.”

For a heartbeat, he did not move.

Then Bram appeared in the kitchen doorway.

Bram was not tall enough to intimidate by height, nor broad enough to intimidate by size. His power lay in stillness. He was Lucien’s man in the old way—driver, guard, errand-runner, perhaps worse. His face bore an old knife scar across one cheek, and his eyes had the mild patience of someone who could wait all day to break a wrist properly.

“Problem?” Bram asked.

Moran grabbed the kindling.

“No problem.”

“Good,” Bram said. “I hate problems before luncheon.”

Isolde did not exhale until Moran left.

Elspeth watched her with new consideration. “You’ll want broth sent up.”

“Yes.”
