The heavy velvet curtains muffled the sound of the rain. Arthur lay very still upon the cold marble floor tiles. A single crimson stain bloomed across his crisp white shirt. The grandfather clock struck midnight with a slow, heavy chime. Detective Miller stepped quietly into the dark and dusty study. He noticed the broken glass scattered near the mahogany desk. Nobody heard the fatal shot during the loud summer storm. The smell of bitter almonds lingered in the stagnant air. One silver key remained missing from the heavy brass ring. Fresh footprints trailed from the open window to the hallway. He knew the killer was still hiding inside the house.
