She found him in the library.
She hadn't been looking for him — she'd been looking for the library, specifically, because if there were answers in this house they would be in its books, and she had spent enough time around old manuscripts to know that the things people wrote down were almost always more honest than the things they said out loud.
The library was on the second floor, through a set of doors that were heavier than they looked. Floor to ceiling shelves on three walls. A rolling ladder on a brass rail. A fireplace that was actually lit this time, burning steadily despite the fact that no one appeared to have tended it. Two leather chairs angled toward it, and in one of them — Caelum.
Not Felix. Caelum.
She stopped in the doorway.
He looked up from whatever he'd been reading — or not reading; the book was closed on his knee, and she had the impression he'd been sitting in thought rather than in text. He looked at her for a moment with those dark eyes that gave nothing away and said nothing.
"I was looking for the library," she said.
"You found it."
"I didn't know you'd be here."
"It's my house."
She considered leaving. Then she considered that she had spent the night awake being frightened by a mirror and she was tired of being frightened, and she walked in and went to the nearest shelf and began reading spines.
He didn't speak. She didn't speak. The fire burned steadily. Outside, the fog moved against the windows in slow, contemplative rolls.
The books were extraordinary. Old — many of them older than any she'd catalogued professionally. Texts in languages she recognized and languages she didn't. Volumes with no titles on their spines at all, just symbols pressed into leather. She kept her hands clasped behind her back out of professional habit — you didn't touch without permission — but her eyes moved hungrily.
"You can take any book you want," he said.
She glanced at him. He was watching her with an expression she was beginning to recognize — that particular quality of attention he gave her that he seemed to give nothing else. Focused. Searching. Like she was a text he was trying to read.
"Any book?"
"Any on these shelves."
She noted the qualification. These shelves. "And the ones not on these shelves?"
Something moved at the corner of his mouth. "Don't push."
She turned back to the books. Pulled one out — a slim volume, dark blue cover, title in a script she half-recognized. She opened it. The language inside was one she'd catalogued before, an archaic form that had been dead for three hundred years.
"You read that?" he said.
"A little. I catalogued a collection of manuscripts in this language two years ago. My employer never told me what they were." She paused. "I'm starting to think that wasn't an accident."
Silence.
She looked at him. He was very still in the way he got when something she said landed closer to something true than he'd expected.
"Caelum." She said his name the way she always did — without ceremony, without the flinch. "The job I had. The one cataloguing manuscripts. Did you know about it?"
He held her gaze for a long moment.
"Yes," he said.
The word fell into the room like a stone into still water, and she felt the ripples move through her — not surprise exactly, because some part of her had already suspected, had been building toward this suspicion since she'd woken up in this house. But hearing it confirmed was different from suspecting it.
"How long have you known about me?" she asked.
"Long enough."
"That's not an answer."
"It's the only one I have right now."
She closed the book carefully. Set it back on the shelf with the precision of someone who needed to do something with her hands. "You said last night that you didn't bring me here."
"I didn't."
"But you knew I was coming."
A pause. The longest one he'd given her yet. "I knew someone was coming," he said finally. "I didn't know it would be you."
She turned that over. I didn't know it would be you. Said with something in it she couldn't name — not quite relief, not quite its opposite.
"What did you think it would be?" she asked.
He looked at her for a moment longer than was comfortable. Then he picked up his book and opened it and said, with a finality that closed the conversation like a door: "Something worse."
She found Felix in the garden.
Or what passed for a garden in Noirheim — a walled space behind the east wing where things grew that didn't seem to require sunlight, pale-leafed and strange and somehow thriving in the perpetual dimness. Felix was sitting on a stone bench with his hands around a cup, looking at nothing in particular with the expression of someone working through something difficult.
He looked up when he heard her. "Survive the library?"
"He was in there."
"Ah." Felix shifted on the bench. "How was that?"
"Informative." She sat beside him. "He knew about me. Before I came here. He knew someone was coming."
Felix was quiet for a moment. "He told you that?"
"He confirmed it when I asked."
"Hm." He drank from his cup. "That's more than he usually tells anyone."
"Felix." She turned to face him. "I need you to tell me something true. Not managed. Not careful. Just true."
He looked at her sideways. She could see him weighing it — loyalty to his brother against something else. Something that looked, she thought, like the particular guilt of someone who had been keeping a secret they weren't sure they should be keeping.
"What do you want to know?" he said carefully.
"The thing in this house." She kept her voice level. "The thing below the ground floor. The reason the mirrors are wrong and the silence comes at 2 a.m. and you looked frightened this morning when I mentioned it." She held his gaze. "What is it?"
Felix went very still.
She watched the conflict move through him — visible, honest, entirely unlike his brother. His jaw tightened. His eyes dropped to his cup.
"Felix—"
"There are things," he said slowly, "that Caelum needs to tell you himself. In his own time. In the right order." He paused. "Because if you hear it wrong — if you hear it without the context, without understanding what it cost him — you'll run. And if you run—" He stopped.
"If I run, what?"
He looked up at her then. And what she saw in his face made her breath catch — not fear exactly. Something older and heavier than fear. Something that looked like grief for something that hadn't happened yet.
"Just don't run," he said quietly. "Not yet. Give him time to explain it properly." A pause. "Give us time."
The fog moved beyond the garden wall.
Somewhere inside the house — from below, from the place without a name — the silence came again. Brief. Barely there.
Felix heard it too. She could tell by the way his hand tightened on his cup.
Neither of them mentioned it.
They sat in the pale not-quite-morning of Noirheim and didn't say the thing that was sitting between them, large and dark and patient, waiting to be named.
