Detective Sarah Mills knelt beside the body in the rain. Blood mixed with water, creating pink swirls on the ground. The victim's eyes stared blankly at the stormy gray sky. A single playing card rested in her cold, lifeless hand. Uniformed officers whispered among themselves, casting worried sidelong glances away. Sarah noticed small puncture marks trailing down the victim's neck. The Queen of Hearts was stained crimson with fresh blood. Lightning flashed overhead, illuminating the scene in stark white light. This was the third body they had found this month. The killer was playing games, and Sarah hated playing games.
