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. Footsteps pounded down the staircase, frantic and unevenly spaced. A body lay sprawled across the library’s Persian rug. Blood pooled around the victim’s head, dark and glistening. The butler’s hands trembled as he clutched a silver tray. Whispers spread like wildfire among the shocked, well-dressed crowd. Cole knelt beside the corpse, his mind already racing. Someone here was a killer, and time was running out.
