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. Guests froze, their laughter dying in the flickering candlelight. The butler’s hands trembled as he clutched a silver tray. Blood seeped beneath the study door, dark and unnervingly still. Whispers spread like wildfire among the nervous, well-dressed crowd. Cole pushed through, his boots clicking on the marble floor. The body lay sprawled, a letter opener buried deep in chest. Someone here was a killer, and time was running out.
