The rain drummed against the old mansion’s grimy windows. Fog curled like a ghost around the crumbling stone steps. Detective Mara Voss adjusted her damp coat tightly. A single candle flickered in the abandoned drawing room. Footsteps echoed where no one should have walked. The air smelled of lavender and something far worse. A bloodstained handkerchief lay crumpled near the door. Her flashlight trembled as she stepped inside cautiously. The victim’s name was whispered in the hollow wind. Something had gone terribly wrong here tonight.
