My sister called me at midnight and whispered, “Turn off every light. Go to the attic. Don’t tell your husband.” I thought she was losing her mind — until I looked through the floorboards….

I answered in a whisper. “Mara?”

Her voice was tense. “Listen carefully. Turn everything off. Your phone, the lights, everything. Go to the attic, lock the door, and don’t tell Caleb.”

A chill ran through me. “What?”

“Now, Elise.”

I glanced at my husband. He lay facing away, breathing slow and steady.

“You’re scaring me,” I whispered.

Mara’s voice snapped into a shout. “Just do it!”

I moved before I could question it.

I slipped out of bed, grabbed my phone charger without thinking, and crept into the hallway. Behind me, Caleb shifted.

“Elise?” he murmured.

I froze.

“I’m getting water,” I said.

He didn’t respond.

I switched off the hallway light, then the kitchen, then the living room lamp Caleb always left on. My hands trembled so badly I nearly dropped my phone. Mara stayed on the line, silent except for her breathing.

At the attic stairs, she whispered, “Do not hang up.”

I climbed slowly, each wooden step creaking beneath my bare feet. The attic smelled of dust, insulation, and old holiday boxes. I shut the door behind me and slid the small latch into place.

“Lock it,” Mara said.
