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. 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 unmistakably final. Cole lit a match, its glow revealing a body on floor. Blood pooled around the victim, dark and spreading slowly outward. The butler stood trembling, clutching a silver candlestick tightly. Someone in this room is a murderer, Cole thought grimly.
