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 sudden. Guests froze, their laughter dying in an instant. The lights flickered once, then plunged the room into darkness. A thud followed, heavy and unmistakably final. Cole lit a match, its glow revealing a body. Blood pooled around the victim’s head in a slow spread. The butler stood pale, clutching a silver candlestick tightly. Someone in this room was hiding a deadly secret.
