The grand mansion loomed under a stormy, moonless night sky. Detective Cole adjusted his hat as rain began to fall. A scream echoed through the halls, sharp and terrifyingly brief. The guests froze, their laughter dying in an instant. Cole rushed toward the sound, his pulse quickening with dread. A body lay sprawled across the library’s Persian rug. Blood pooled darkly beneath the victim’s motionless, outstretched hand. The butler stood pale, clutching a silver candlestick tightly. Whispers spread like wildfire among the shocked, hushed crowd. Someone here was a killer, and Cole knew time was short.
