Fog hung heavy on streets. Sirens wailed in the distance. A body lay near lamppost. Detective Gray arrived, eyes sharp. Crowd gathered, whispers filled air. No one moved, tension thick. Rain began to softly fall. Gray knelt down, examined clues. Blood stained the cracked sidewalk. Sudden footsteps echoed behind Gray. He spun, hand on gun. Silence answered, shadows danced nearby. Gray’s mind raced, case opened.
