The rain whispered secrets against the grimy windowpanes of the old abandoned manor house while shadows danced wildly inside tonight. A sudden scream shattered the heavy silence that hung over the grand hall filled with dust and forgotten memories. Detective Miller stepped forward slowly, his trusty revolver resting safely within his worn leather coat pocket as he listened. Beneath the flickering chandelier, a body lay sprawled across the cold marble floor near the fireplace while blood spread outward. The victim wore a tuxedo stained with crimson, and a single playing card rested gently upon his pale chest now. Every guest gathered in the corridor stood frozen, their faces pale with shock and absolute terror at the scene. The butler clutched his silver pocket watch tightly, his eyes darting toward the locked oak door at the end. Someone here pulled the trigger, and the killer must remain hidden until dawn breaks over the distant hills outside. Miller raised his revolver, scanning every pale face in the dim light to locate the hidden murderer within shadows. This deadly game of life had just begun, and the hunter might soon become the hunted prey before long.
