Rain fell hard on Blackwood. Lightning cracked across the sky. Detective Moore stepped through mud. The old house loomed silent. A scream echoed from inside. He drew his weapon slowly. The door creaked open wide. Blood stained the marble floor. A body lay near stairs. Moore knelt beside the corpse. Her eyes stared into nothing. Something glinted beneath her hand. He picked up a note. The words chilled his spine. "You're too late," it read.
