The lake water stayed motionless. Mist clung to every surface. Detective Crane adjusted his collar. His footsteps made no sound. The dock creaked beneath him. He knelt beside the body. Her dress was pale blue. It was soaked completely through. A single diamond rested nearby. No blood marred her skin. He recognized her earrings first. His own niece lay dead. He saw her lips part. A whisper escaped into mist. "You're too late, Uncle James." He did not feel shock. He felt the blueprint shift. Her hand clutched a key. It opened a forgotten church. The game had just begun.
