Wind howled. Rain lashed. Victim lay still. Blood pooled slowly. Detective arrived early. Scene was grim. She wore a long coat. Her face was stern. Pockets held a small book. A pen clicked open. She saw the victim. A jeweler. Ring missing from finger. His last act? She knelt beside him. Studied the scene. Every detail mattered greatly. A faint shimmer. It glistened on his cheek. A tiny fiber. Not from his ruined suit. Unknown for sure. A single red hair. Her brows furrowed.
