The rain drummed against the old mansion’s grimy windows. Fog curled through the garden like a ghost’s breath. Detective Mara Voss adjusted her damp overcoat carefully. A single candle flickered in the abandoned study’s corner. Footsteps echoed where no one should have walked yet. The air smelled of lavender and something far worse. A letter lay open on the desk, ink still wet. *"Meet me here if you dare,"* the words read clearly. Her pulse quickened as the front door creaked shut. Something had gone terribly wrong inside this house tonight.
