Ivy read it three more times.
*Catriona. She works for them.*
Same handwriting. Same red circle. Her mother's hand, her mother's certainty, written in a hidden room years before Ivy had ever sat across a private dining table and let a woman with careful eyes and a burgundy dress tell her things about Claire Caine that had felt like gifts.
"The second letter," Ivy said.
Her voice came out steady. She was proud of that.
"What about it?" Aiden said.
"Elara's letter. Catriona said Elara left it in her care. Said it was sealed when Elara gave it to her, that she'd kept it that way for years." Ivy looked up at him. "If Catriona works for V... "
"The letter might not be from Elara at all," Aiden said quietly completing her statement.
"Or it's from Elara but Catriona read it and knew exactly what was in it before she gave it to me." Ivy set the notebook down carefully on the desk. "She directed everything I found out. The corner seat, the photograph, Elara's name, the second letter. She built a path and walked me down it." She paused. "The question is where the path was leading."
Aiden was already on his phone.
"What are you doing," she said.
"Checking when Catriona last accessed the building." He was moving through something fast, his expression tight. "She has a key card. All long-term guests do. Every entry is logged." He stopped. Read something. "She was here two nights ago. After midnight."
"The building was closed."
"Yes."
"So she has after-hours access."
"She shouldn't." His jaw was tight. "I didn't authorize that."
"Then who did."
He looked up from the phone. The expression on his face was the specific one she'd learned meant he was running through possibilities and not liking any of them.
"Someone with admin access," he said. "Which is myself, Mira, and one other person with backend system rights." He paused. "Elara had those rights. When she died I transferred them to an external security company." He stopped. "I need to make a call."
"Okay. Make it."
He stepped to the corner of the small room, phone to his ear, voice dropping to something clipped and quiet. She turned back to the notebook.
She read while he talked.
Her mother had documented Catriona across four pages. Not aggressively, not with panic, with the same careful precision she'd applied to everything. Observations. Timings. Small inconsistencies that individually meant nothing and collectively meant everything.
*C always arrives after the room is established. Never the first guest. Studies arrivals. Positions herself for maximum visibility.*
*C asked about my background twice in one week. Casual framing. Not casual interest.*
*C knows things she shouldn't know. Mentioned a detail about my previous address. I never told anyone here where I lived before.*
Ivy stopped on that one.
Her previous address.
The same thing V's man had done to Ivy. The same playbook. Demonstrating access without explaining it. Letting the knowledge sit and do its quiet terrifying work.
"She was running the same operation on my mother," Ivy said, half to herself.
Aiden finished his call. Came back to stand beside her. She showed him the page.
He read it. Said nothing for a moment.
"The security company that has Elara's admin access," he said. "They were acquired eight months ago. New parent company." He paused. "I'm having it traced right now but I already know what it's going to come back as."
"A Voss shell company," Ivy said.
"Yes."
She looked at the wall. At years of her mother's work covering it. At a woman who had sat alone in this room piecing together the same thing Ivy was piecing together right now and had run out of time before she could use it.
"They have access to the building systems," Ivy said. "Security. Entry logs. Cameras possibly."
"Possibly."
"Which means they've known I was here since day one. Not just from external surveillance. From inside."
"Yes."
"Which means—" she stopped. Thought it through. "Aiden. This room. If they have camera access..."
"No cameras in the private corridors," he said. "I had them removed three years ago when I started suspecting the system had been compromised. The staff know but I didn't make it public." He looked at her directly. "This room is clean."
She breathed out slowly.
"Okay," she said. "Okay."
"Ivy."
"I'm fine."
"You've just found out that a woman you spoke to twice fed you controlled information on behalf of the people hunting your family. You're allowed to not be fine."
She looked at him.
At the low lamplight. At the open careful honest face that had been the same face since the beginning, since an office and a desk and 'you're late' and she'd lied about traffic and somehow none of it had ever felt like performance.
"I keep thinking about what she told me," Ivy said. "About my mother. The things she said about Claire that felt true. That she loved you in the way people love the one thing they did completely right." Her voice did something at the end. "Was that real or was that something she said because she knew it would land and hit the right mark."
Aiden was quiet for a moment.
"I think," he said carefully, "that the most effective lies are the ones built around true things." He held her gaze. "Your mother did love you that way. Catriona didn't invent that. She used it."
Ivy nodded.
She looked down at the notebook in her hands.
"I have to tell Sera," she said. "Tonight. All of this."
"Yes."
"And Lena. I need to talk to Lena."
"Carefully."
"Obviously carefully." She looked up at him. "And Mira. Does Mira know any of this?"
"Mira knows I suspected the system had been compromised. She doesn't know about this room." He paused. "She doesn't know about Catriona."
"We tell her tomorrow. She needs to know."
"Agreed."
She stood up from the chair. Looked around the small hidden room one more time. At her mother's wall of research, the years of careful patient dangerous work. At the desk and the lamp and the notebook that had been waiting here in the dark for someone to find it.
She'd found it.
She picked up the notebook and held it against her chest.
Aiden was watching her. She could feel it even before she turned.
"Hey," she said.
"Yeah."
"The thing she wrote at the front. Don't trust the person who brought you here." She looked at him steadily. "I've decided."
He held very still.
"You kept the promise," she said. "For sixteen years. To a woman who was afraid and running and handed you the most important thing she had." She paused. "That's not what someone who works for them does. That's not what that looks like."
Something moved through his expression.
"Ivy..."
"I'm not finished." She stepped closer. "You told me things that made you look bad when you could have left them out. You told me Elara didn't trust you. You told me to be careful with Catriona before I had a reason to be. You've been honest even when honest was complicated." She looked at him. "My mother wrote that warning when she was scared and alone and didn't know who was safe. By the time she made you promise she'd already decided." She paused. "So have I."
He looked at her for a long moment.
Then he reached out and tucked her hair back from her face, the same gesture as before, slow and deliberate.
"You're going to be the thing that breaks my composure completely," he said quietly. "You know that."
"Good," she said. "It needed breaking."
His mouth curved. The real smile this time. Not the corner-of-the-mouth version she'd been collecting. The actual one, warm and specific and entirely for her.
She'd been waiting for that one without knowing she was waiting for it.
His phone buzzed.
She groaned. "I hate your phone."
He laughed.
The fourth almost-laugh became the first real one and it was even better than she'd imagined and she stood in her mother's hidden room at one in the morning holding a notebook full of answers and looked at this man laughing quietly in the lamplight and thought:
...Oh. I'm in serious trouble...
"Sera," he said, reading the message. His expression shifted back to business. "She needs us now. Both of us."
"What happened."
He showed her the screen.
*Catriona just tried to access the building. System flagged it. She's outside right now.*
Ivy looked at the message.
Looked at the door of the hidden room.
"She knows we're here," Ivy said.
"Maybe."
"Aiden." She looked at him. "If she works for them and she's outside right now at one in the morning..."
"She doesn't know about this room," he said. Calm. Certain. "No one does. We're safe in here."
"For now."
"For now," he agreed.
He held out his hand.
She took it.
"Deep breaths " he said.
They walked out of the hidden room together into Velvet House's dark corridors and to whatever was waiting on the other side of the front door.
