A WEEK BECAME EIGHT YEARS

Emma was ten minutes late that evening.

I saw her from the study door, one hand pressed against the laundry cart, staring at her phone. Her eyes were swollen. When she noticed me, she put it away too quickly.

"My mother," she said before I asked. "I called Mrs. Alvarez."

"She told me."

"I'll make up the time."

"You don't need to."

She waited. By then, she knew there was usually another sentence.

"Do you need the night off?"

"No."

"You can take paid leave."

"Since when?"

"Since I authorize it."

The response sounded generous to me. It sounded dangerous to her. I watched the distinction pass across her face.

"Then it's a favor."

"It's wages."

"For a shift I don't work."

"You were here when I needed help."

"I wasn't keeping a tally."

I looked down the corridor. A guard stood by the service entrance. She had already noticed him, though she hadn't asked about him.

"Neither was I."

"Then let me work. It's easier."

I should have let the conversation end there.

Instead, I said, "Did your mother work for Northstar?"

Emma went motionless.

Her hand remained on the cart. The folded towels between us suddenly felt like a barrier someone had built deliberately.

"Where did you hear that?"

"The company serviced this house."

"Years ago?"

"Yes."

She lowered her eyes.

"She handled office accounts. Before she got sick."

"And Daniel Carter?"

Her head lifted sharply.

"You investigated me."

"We investigated the system."

"And then me."

I said nothing. The silence was more honest than the answer I'd prepared.

She stepped away from the cart.

"How much?"

"Enough to find the connection."

"That's not an amount."

"His name was in the contractor records. Luke confirmed he's your father."

She looked toward the guard and then back at me.

"Is that why he's there?"

"Someone entered the private wing without permission."

"And you think I let him in."

"I don't know what to think."

I saw how much that hurt her.

She had watched me unable to hold a glass. She had fallen asleep waiting for someone to help me. Now I stood on the only ground I still knew well: gather facts, distrust everybody, keep control.

"I haven't spoken to my father in eight years," she said.

"Why?"

"Because he left."

Her voice was so flat that I almost missed the effort beneath it.

"Where did he go?"

"If I knew, I wouldn't be explaining that he disappeared."

"He owned Northstar."

"Yes. I knew that. I didn't know your address was a client."

"Did you recognize any equipment when you arrived?"

"A door lock looks like a door lock to me. I was eighteen when his company fell apart. I wasn't installing security systems."

She rubbed her thumb against the crack in her other hand.

"He left a note. He said he needed a week to sort something out. A week became a month. My mother stopped opening the letters because they were all bills. I opened them instead."

I couldn't speak.

"We lost the apartment. Her memory got worse. At first she asked when he'd be back. Later she asked who I was. Those are the things I know about my father, Danny. His access codes weren't part of them."

The guard shifted down the hallway. I turned my head, and he looked away.

I had never wanted anyone to look away more.

"Why this job?" I asked.

Emma's mouth tightened.

"Because the agency pays more for nights. Because my mother's care costs money. Because I could reach it by bus. Which answer sounds least suspicious?"

"Emma—"

"The agency gave me a staffing code and an address the day before I started. Nobody told me who lived here until Mrs. Alvarez did."

"Did anyone contact you about the house?"

She opened her mouth, then stopped.

I saw the recollection arrive.

"A man called," she said slowly. "Before my first shift. He said he was checking the placement."

"From the agency?"

"That's what he said."

"What did he ask?"

"Whether I'd started. Whether the private wing still used the old system. I didn't know what he meant."

"What did you tell him?"

"That he should ask the housekeeper. Then I hung up."

"Did you keep the number?"

"It was withheld."

"What did he sound like?"

She closed her eyes briefly.

"Older. Calm. He said something strange."

"Tell me."

"The door still opens for the right person."

I looked toward the service staircase.

The phrase belonged to someone who knew exactly what was wrong with my house.

"Why didn't you report it?"

"Because I thought it was a scam. I had three calls about debt that afternoon. One about insurance. One from someone asking me to verify information they should already have had. I didn't know this one mattered."

She was right. I had security men to sort inconvenient information from danger. She had a phone, two jobs, and a mother who might stop recognizing her between breakfast and dinner.

I had treated those differences as weaknesses I could investigate.

"I should have asked you before I had Luke look into your family," I said.

She watched me.

"Would you have believed me?"

I wanted to say yes. The speed of the answer would have exposed it.

"I don't know," I admitted.

Emma nodded once, as if I had finally answered the actual question.

"Thank you for being honest."

It didn't sound like forgiveness.

She pushed the cart toward the linen room.

"You don't have to stay tonight."

"I need the hours."

"I meant—"

"I know what you meant. I'll finish the work."

She left me in the corridor.

For half an hour, I heard drawers opening, towels being placed on shelves, and the soft click of the cart. Ordinary sounds. They had never felt so remote.

I called Luke and gave him the details of the telephone call. I told him to ask Emma's permission before copying her messages or looking at anything else.

He went quiet.

"That includes her mother's records," I added.

"Understood."

I almost asked whether he thought she would forgive me. I had managed enough humiliation for one evening.

Later, Emma emerged carrying the empty basket.

I moved out of her path before she asked.

She stopped.

"I'm not hiding anything from you."

"I know you haven't hidden the things I've asked about."

Her face tightened again.

I took a breath.

"That sounded worse than I intended. I believe what you told me."

"You still need proof."

"About who entered the house. Not about whether your father hurt you."

She looked away. After a moment, she nodded.

It was a small piece of ground to regain, but I took it carefully.

A faint glint caught my eye near the service stair.

A brass key lay beside the bottom step.

Emma followed my gaze and crouched, then stopped before touching it.

"That wasn't there earlier."

"Leave it."

Luke appeared at the other end of the corridor, walking faster than usual. He held a printout in one hand.

"The technician recovered the underlying override records."

He looked at Emma, then at me.

"The contractor credential that opened your bedroom belonged to Daniel Carter."

Emma's fingers curled against her knee.

Luke lowered the paper.

"And it was used again ten minutes ago."
