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 suddenly cut short. The guests froze, their laughter dying in an instant of dread. Footsteps rushed toward the study where the body was found. Blood pooled around the victim, a letter opener in his chest. The butler stood pale, clutching a silver tray with trembling hands. A shattered vase lay near the fireplace, its pieces scattered across the rug. The detective knelt, examining the scene with a cold, calculating gaze. Someone in this room was a killer, and he would find them.
