Rain tapped against the window. A clock chimed midnight precisely. Footsteps echoed in the hallway. Lucy gripped her silver candlestick. Shadows danced across the walls. A whisper floated through air. The door creaked behind Lucy. She turned, heart beating fast. Blood pooled beneath the rug. A gloved hand closed tightly. Lucy gasped in cold terror. A scream sliced through the darkness.
