The silver moonlight spilled across the cold marble floor where his lifeless body lay still in the silent, empty hall. Shadows stretched like jagged fingers toward the velvet curtains that fluttered softly in the damp wind of the night air. A single shattered glass rested nearby, its contents staining the priceless antique rug with a dark and deep crimson hue. Somewhere in the distance, an ancient clock chimed twice, marking the hour when the secrets finally escaped their heavy tomb.
