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 bloodcurdling. Guests froze mid-conversation, their faces pale with sudden dread. The lights flickered once, then died, plunging all into darkness. A thud came from the library, heavy and unnaturally loud. Cole lit a match, its glow revealing a body on floor. The victim’s eyes stared blankly, a knife in his chest. Whispers spread like wildfire as panic gripped the gathered crowd. Someone here was a killer, and Cole would find them.
