The rain drummed against the old mansion’s grimy windows tonight. Flickering gaslight cast long shadows across the abandoned hallway floor. A single footstep echoed where no one should have walked. The air smelled of damp wood and something far more sinister. Dr. Eleanor Vane adjusted her spectacles, her pulse quickening slightly. Outside, the wind howled like a warning through the broken panes. Her late husband’s study door stood ajar, defying all reason. Inside, the inkwell lay shattered—pages torn from his journal. A gloved hand rested on the desk, fingers stiff as stone. The name *"Lydia"* was scrawled in blood across the wall.
