Chapter 1

The Locked West Wing Door

Rain struck the iron gates of Harrowgate Mansion like handfuls of thrown gravel.

Clara Wren pushed through them just as lightning whitened the grounds. For one sharp second, the mansion stood clear above the black lawns: three stories of gray stone, narrow windows, and chimneys bending beneath the wind. Then darkness swallowed it again.

“Miss Wren!”

Martin Quill’s voice came from the front steps. The butler held a lantern in one hand and the open door with the other. His silver hair was plastered to his forehead, and his usually exact collar hung crooked.

Clara ran toward him, one hand clamped around the leather case beneath her coat. Mud tugged at her boots. Water streamed from the brim of her cap.

“You said the west wing was locked,” she called.

“It is.”

“Then why did you ask me to come?”

Quill’s face tightened as thunder rolled over the estate. “Because something struck the door from the other side.”

Clara reached the steps. “When?”

“Ten minutes ago.”

“And who is inside?”

“I don’t know.”

That answer followed her into the mansion.

Quill slammed the door behind them. The storm became a muffled battering against the oak, but the house was not quiet. Somewhere above, a loose shutter banged in a steady, frantic rhythm. Water dripped from Clara’s coat onto the marble floor.

She shrugged it off and opened her case.

Quill watched her remove a small flashlight, a folding magnifier, and a narrow steel pick. “You came prepared.”

“I came prepared to inspect a locked room.” Clara glanced toward the staircase. “Not to be trapped in one.”

A tremor passed through the chandelier overhead. The lights flickered once.

Quill looked up. “The generator should hold.”

“Should?”

Before he could answer, every lamp in the entrance hall went dark.

The mansion dropped into a deeper black than the storm outside. Clara heard Quill’s breath catch. Then his lantern flame fluttered alive, painting his face in gold and hollow gray.

“West corridor,” Clara said.

“Miss Wren, perhaps we ought to wait for the electrician.”

“If there’s someone in that wing, waiting gives them time to leave.”

Quill’s fingers tightened around the lantern handle. “The wing has been sealed for twenty-two years.”

“Then whoever struck the door has had a very long morning.”

He stared at her.

Clara was already moving.

The west corridor began beyond the grand staircase, where the polished marble gave way to dark oak flooring. The temperature fell as they walked. Cold slipped beneath Clara’s damp sleeves and settled along her wrists. Portraits lined the walls, their painted eyes catching the lantern light one at a time.

At the far end stood a tall door of black wood banded in iron.

No handle showed on its outer face.

Clara stopped three paces away.

Quill lifted the lantern. “There.”

A thin line of dust lay across the floor before the threshold. It had been broken near the center, as if something heavy had scraped over it from within. The door itself bore three pale marks at shoulder height.

Clara crouched. The marks were fresh. Splinters curled outward from the wood.

“Something hit this,” she said.

“Or someone.”

“From inside?”

Quill did not answer.

Clara placed her palm against the door. The wood was cold enough to sting. She leaned closer.

Tap.

A sound came from the other side.

Quill raised the lantern. “You heard that.”

Clara did not move.

Tap. Tap.

Not a knock. Something lighter. Deliberate.

“Who is there?” she called.

The storm roared through the walls.

No answer came.

Clara slid her fingers over the door’s edge, searching for a latch, a keyhole, any weakness. There was nothing. The iron bands disappeared into the frame, and the seam was so narrow that even a fingernail could not enter it.

“The lock is on the inside,” she said.

Quill’s voice dropped. “That is impossible.”

“Most locked doors are not.”

He stepped closer. “The west wing was closed after Lord Harrowgate died. The key was removed, and the inner bolt was drawn. No one has entered since.”

“Yet something is moving in there.”

A flash of lightning shone through the high windows. For an instant, the corridor filled with white light. Clara saw a dark smear on the floor just beyond the threshold, visible through the hairline gap beneath the door.

Mud.

She reached for her magnifier.

The lights came back.

Then the door gave a sudden, violent shudder.

Quill stumbled backward. The lantern swung, throwing light across the portraits. Clara caught the door with both hands. Something struck it again from within, hard enough to rattle the iron bands.

“Move away!” Quill shouted.

Clara pressed her shoulder into the wood. “If someone is hurt - ”

Another blow shook the corridor. Dust sifted from the frame and fell across Clara’s knuckles.

Then silence.

The quiet afterward felt worse than the impact.

Clara lowered her hands. “Open it.”

Quill stared at the blank outer face. “I told you. There is no key.”

“Then find one.”

“I have searched the house.”

“Search again.”

His jaw worked. “Miss Wren, you don’t understand. The west wing is not merely locked. It is forbidden.”

Clara turned on him. “A forbidden room does not make a sound when struck.”

The butler’s gaze flicked toward the portraits. “There are reasons - ”

A sharp electrical click sounded overhead.

Every light died again.

This time the darkness was followed by a shrill tone from somewhere deep within the mansion.

Quill went still.

“What is that?” Clara asked.

He did not answer.

The tone stopped. A red glow appeared beneath the west-wing door, thin as a line of blood.

Clara knelt. The glow pulsed once.

“Martin.”

“I have never seen that before.”

“Neither have I. Which means we are both late.”

She took the flashlight from her case and swept its beam over the corridor. The red light under the door had vanished, but a faint ticking had begun on the other side.

Not a clock. Too uneven.

A mechanism winding down.

Clara stood. “How thick is the door?”

“Solid oak.”

“And the hinges?”

“On the inside.”

“Of course they are.”

Quill seized her arm. “You cannot break into that wing.”

Clara looked at his hand until he released her.

“If someone sealed themselves in,” she said, “they may have sealed something else out. Or trapped someone inside. Either way, we need to know before the storm cuts us off completely.”

“The roads are already flooded.”

“Then we have less time.”

A gust slammed against the mansion. The windows groaned. Somewhere upstairs, glass shattered.

Quill flinched toward the sound.

Clara saw it then: fear, not of the storm, but of the door.

“You know what is in there,” she said.

His face hardened. “I know what happened the last time it opened.”

“What happened?”

The ticking quickened.

Quill glanced at the threshold. “Lord Harrowgate’s daughter disappeared.”

“Twenty-two years ago?”

“Yes.”

“And no one looked in the west wing?”

“We did.”

“Then someone lied.”

She turned to the door and drew the steel pick from her case. The narrow tool looked absurd against the heavy wood, but Clara had never trusted a lock merely because it was large. A lock was a question. Every question had a weak point.

She ran her fingers along the frame again. The door had no external latch, but the lower hinge-side molding sat slightly proud of the wall. She wedged the pick beneath it and pried.

The wood flexed.

Quill grabbed the lantern with both hands. “What are you doing?”

“Finding the part of the door someone expected no one to notice.”

The molding cracked. Behind it, a strip of brass gleamed.

Clara leaned closer. A wire ran from the brass strip into the stonework.

“An alarm,” she whispered.

Quill’s face drained of color. “Don’t touch it.”

“Was it installed twenty-two years ago?”

“No.”

“Then who installed it?”

The ticking became faster.

Clara slipped the pick beneath the brass and lifted. The strip sprang free. A small metal cylinder was hidden behind it, its needle trembling above a row of tiny numbers.

The needle moved.

Ten.

Nine.

“Clara,” Quill said.

She looked at him. “You know this device.”

“I know enough to tell you that if it reaches zero - ”

“What?”

He swallowed. “The wing will not remain sealed.”

Eight.

Clara glanced at the door. “You mean it will open?”

“I mean the house will answer.”

Seven.

The corridor seemed to narrow around them. Wind moaned through the walls, and the portraits trembled in their frames.

Clara pocketed the cylinder.

Quill stared. “Why would you do that?”

“Because whoever set this wants us to panic.”

“It may be connected to something worse.”

“Then I would rather carry the warning than leave it where it can surprise us.”

Six.

She dropped her case, braced one boot against the wall, and drove the steel pick into the gap beside the door. The wood resisted. Her shoulder burned as she leaned into it.

“Help me,” she said.

Quill hesitated.

“Martin!”

He set down the lantern and joined her. Together they pushed. The door groaned, but the seal held.

Five.

Clara changed her grip and felt the pick catch on something metal inside the frame.

A bolt.

She twisted hard.

The pick snapped.

The broken end cut her palm. Heat flashed through her fingers, followed by the slick warmth of blood.

Four.

Quill swore under his breath. “Stop.”

Clara wrapped her injured hand in the edge of her sleeve. “No.”

She reached into her case and pulled out the flat steel ruler she used for measuring footprints. It was thin, rigid, and long enough to reach the bolt.

Three.

She slid it into the gap.

The metal scraped. The bolt shifted a fraction.

Two.

Clara threw her weight against the door.

The ruler bent. The bolt screamed across its housing.

One.

The door burst inward.

A gust of freezing air tore down the corridor, extinguishing Quill’s lantern. Clara stumbled across the threshold and caught herself against the wall inside.

The west wing smelled of wet stone and something sharply metallic.

Her flashlight beam cut through the darkness.

The passage beyond was narrow, choked with dust, and lined with covered furniture. Rainwater dripped from the ceiling. A trail of muddy footprints crossed the floor, each print clear enough to show the tread of a boot.

They led away from the door.

Clara crouched, her injured hand throbbing. The prints were fresh. Water still shone in the grooves.

“Someone is in here,” Quill whispered behind her.

Clara followed the beam farther down the passage. The footprints turned toward a staircase descending into darkness.

Then the cylinder in her pocket began to beep.

Once.

Twice.

A red number glowed through the fabric of her coat.

00:59.

Quill’s voice broke. “What is it?”

The alarm beeped again.

00:58.

From somewhere below, a door slammed.

Clara rose, gripping the flashlight in one hand and the bloodied ruler in the other.

“Now,” she said, staring down the stairwell, “we find out what the clock is counting toward.”
