“The mind is a house,” he said. “Sometimes you have to walk through the ruins to find what was buried.”

“What did you bury?” I asked.

He did not answer.

“You need to let her go to Lily’s room,” Nathan said.

I stared at him, unable to believe what I was hearing.

“Are you out of your mind?” I breathed.

“It is part of the process,” he said. “She needs to see a child in that room. It triggers her.”

“I will not let you use our daughter as some kind of psychological experiment,” I said.

Nathan turned back to me.

His expression was dead, completely devoid of emotion.

“You will,” he said. “If you want us to remain a family.”

“Is that a threat?”

“It is a fact,” he said. “I am trying to heal us, Clara. All of us.”

“By letting a unstable woman haunt our daughter at night?”

“It is the only way she will remember where she put it,” he said.

“Put what?” I asked.

Nathan didn’t answer.

He walked past me to the door.

He unlocked it, the metal clicking sharply in the quiet.
