The old mansion stood silent against the dark winter sky. Detective Harris stepped out of her car into the rain. A single light flickered behind curtains on the third floor. Someone had called the station about a body at midnight. She pulled her coat tighter and walked toward the door. The front door was unlocked, which struck her as strange. Inside, the foyer smelled of roses and something far worse. Her flashlight beam cut through the heavy darkness like glass. A man lay crumpled at the bottom of the stairs. His eyes were open, staring at nothing but the ceiling. Blood had pooled beneath his head in a dark halo. Harris knelt beside the body and studied the man's face. She recognized him instantly and felt her stomach drop hard. It was Judge Whitmore, the most powerful man in town. This was no accident, and she already knew it well. Somewhere above her, a floorboard creaked in the empty house.
