The grand mansion loomed under a stormy, moonless night sky. Detective Cole adjusted his coat 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 sprinted toward the sound, his pulse quickening with dread. A body lay sprawled across the library’s Persian rug. Blood pooled around the victim, dark and glistening in firelight. The butler stood pale, clutching a silver candlestick tightly. Whispers spread like wildfire among the shocked, well-dressed crowd. Someone here was a killer, and Cole would find them.
