Read Chapter 6: The Hidden Door

The gatehouse clock struck half past eleven as Eilidh slipped out of her quarters, the hammer cold and heavy in her coat pocket. Rain had stopped an hour ago, leaving the courtyard slick and gleaming under a waning moon. She crossed the gravel with soft steps, keeping to the shadows along the western wall, heart hammering against her ribs with each creak of the old stones settling around her.

The east wing door groaned when she pushed it open. She froze, listening. Nothing but the drip of water through a broken slat high above, and the distant hoot of an owl. She stepped inside and pulled the door nearly shut, leaving a hairline gap of light from the corridor behind her.

Her torch beam swept across the great hall's bones—dust sheets draped over furniture like shrouds, scaffolding rising skeletal against the far wall. She moved past the main work area, past the draped piano and the collapsed segment of cornice her team had flagged for immediate attention, until she stood before the east wall. The bulge. The anomaly that had eaten at her since the first survey.

She pressed her palm flat against the cold stonework. The surface was uneven beneath her fingers, stone and lime plaster patched haphazardly over the centuries. But there—where her fingertips found a slight irregularity, a seam running vertical through the masonry, barely perceptible by daylight. She traced it upward, and the seam continued, straight and true, until it vanished into shadow above the first-floor joist line.

Not structural settling. Not a bulge at all.

The plaster here was a lie.

She withdrew the hammer from her pocket, tested its weight, and tapped gently along the seam. The first few strikes returned a dull, solid thud. Then, three inches lower, a hollow answer. Her breath caught. She tapped again, moving outward from the seam, mapping the hollow space with her ears. It ran about four feet wide, and the seam continued around it in an unmistakable rectangle.

A door. Sealed, plastered over, hidden for—she glanced at the chronicle's dates in her mind—perhaps four hundred years.

Eilidh set down the torch, angled it along the seam, and used the hammer's claw to chip at the plaster. It came away in dry flakes, revealing rough stone beneath. But where the door should be, the stones were different—smoother, closely fitted, dressed. She worked faster, scraping away the centuries of concealment, until she exposed the line of a doorframe, its edges cut clean and deliberate.

Her fingers found the join between frame and door and traced upward until they snagged on something cold and metal. A hinge pin, rusted nearly to nothing. She worked it gently with the claw of her hammer, and the pin shifted, then gave way with a screech that echoed too loud in the empty hall.

She froze. Silence. No footsteps. No voice.

She continued.

The second pin took longer. When it finally surrendered, the door itself—a slab of oak six inches thick—remained fixed in place, held fast by centuries of damp and gravity. She leaned her shoulder against the edge and pushed. Nothing. She pushed harder, muscles burning, and felt a tremor run through the wood. Then, with a grinding groan that seemed to come from the very bones of the castle, the door shifted inward an inch.

Cold air rushed out, smelling of earth and old iron and something sweet that Eilidh couldn't place. She pushed again, widening the gap, and the torchlight fell through on a narrow stairwell spiraling downward into absolute blackness.

Not in any plan. Not in any survey. It descended beyond the reach of her beam.

And far below, she heard it: a faint, rhythmic scratching, like nails on stone.

Her hand tightened on the hammer. The sound wasn't inside the wall. It was down there. In whatever this passage led to.

"Step away from that door."

The voice cut through the silence like a blade. Eilidh spun, heart lurching into her throat. Hamish stood in the corridor entrance, backlit by the dim safety light beyond, his frame filling the doorway. He wore a dark sweater and carried no torch himself—he'd come fast, and he'd come knowing exactly where she was.

"Good evening," she said, proud that her voice held steady.

"It's past midnight." He stepped into the hall, boots echoing on the flagstones. "You're supposed to be in the gatehouse."

"I was following a hunch."

"Clearly." His eyes moved past her to the open door, the black maw of the stairwell, and something shifted in his face—anger, yes, but something else beneath it. Fear, maybe. Or grief. "You've been busy."

"The wall isn't unstable, Hamish. You know that."

He said nothing.

"You told me it had been unstable for four centuries. That's a lie. The stonework is sound—I've tested it, logged every reading. Whatever's been holding this wing together is perfectly competent." She gestured at the exposed frame. "This door has been sealed deliberately. Plastered over, hidden. And you knew."

"I knew there was something here." His voice was low, measured. "I didn't know what."

"You could have asked. You could have told me—"

"Told you what?" He moved closer, stopping three feet from her. The torchlight caught his face, the hard line of his jaw, the tension in his shoulders. "That my family's castle has a secret door leading beneath the east wing? That I've spent twenty years keeping people away from it because I don't know what's down there either?" His laugh was hollow. "You'd have been even more relentless."

"Yes," she said simply. "I would have."

Something flickered in his eyes—reluctant amusement, perhaps, or grudging respect. It vanished as quickly as it came.

"You need to seal it." He nodded at the door. "Replace the plaster. Forget what you've seen."

"I can't do that."

"Eilidh—"

"I said I can't." She took a half step back, toward the opening, and his gaze snapped to the stairwell behind her. "This is a Lady's Keep. That chronicle says Lady Mairead built it in 1589. Every record of this castle from that period has been altered or destroyed. The village believes there's a curse on your line, and you—" She stopped, the photograph flashing in her mind. The dark-haired woman in his jacket pocket. "You're hiding something. I don't know what it is, but it's tied to this wing, and I won't walk away from that."

Hamish's jaw tightened. He took another step toward her, and now they were close enough that she could smell the rain on his sweater, the woodsmoke from whatever fire he'd been sitting by. His voice dropped, low and rough.

"You don't know what you're asking for."

"Then tell me."

For a long moment, he said nothing. The scratching from below had stopped, as if the darkness itself was listening. His hand rose, and Eilidh felt her breath catch, expecting—she didn't know what. But he only reached past her, fingers brushing her shoulder as he gripped the edge of the oak door. He pulled. The door swung closed with a sound like a grave closing, sealing the black stairwell away.

"If I tell you, you'll never let it go."

"I'm a restorer. Letting go isn't in my nature."

His eyes met hers in the dim light, and for a heartbeat, the wall between them cracked. She saw exhaustion there, and a loneliness that ran deeper than any castle foundation. Then he blinked, and it was gone.

"Then I won't tell you." He stepped back, but he didn't leave. "This commission comes with conditions, Miss Grant. My conditions. You'll respect them, or you'll find yourself replaced by the end of the month."

"That's not a reason. That's a threat."

"It's both." He glanced at the sealed door, then back at her. "The ground beneath this wing is not stable. Whatever the surveys say, I know this land, I know this castle. I've walked these corridors alone for long enough to understand what it holds." His voice cracked slightly on the final words. "Sealing the door isn't about hiding the truth. It's about protecting what's left."

He turned and walked away, his footsteps fading down the corridor, leaving her alone with the sealed door and the cold thread of air still seeping through its hairline crack.

She stood there for a long time, torch trained on the blank wall. The plaster was gone. The outline of the door was visible now, even in the dim light. If she'd wanted to, she could have pried it open again in minutes.

Hamish had known. And he'd still left her here, alone, armed, and curious.

Either he trusted her more than he'd admit, or he was hoping she'd find the courage he couldn't.

A faint scratching started up again behind the wall. Slower now, almost waiting.

Eilidh switched off her torch and walked back to the gatehouse. The door could wait. The truth could not.
