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. He rushed inside, his boots clicking on the marble floor. The chandelier swayed, casting eerie shadows across the walls. A body lay sprawled near the fireplace, motionless and pale. Blood pooled around the victim, dark and disturbingly still. The butler stood frozen, his face drained of all color. A shattered vase lay nearby, its pieces scattered like clues. Cole knelt beside the body, his mind already racing.
