Rain tapped the dark window. The clock struck midnight loudly. A scream shattered the quiet. I hurried down the stairs. The front door stood open. Cold wind entered the hallway. A body sprawled on steps. Blood stained the pale rug. I checked for a pulse. Nothing moved beneath my fingers. Footsteps echoed above my head. Someone else was inside now. I reached for my phone. The screen showed no signal. Then the lights went out. A whisper came from darkness. "Leave before the police arrive." I recognized that cold voice.
