Detective Miller stared down at the lifeless body lying coldly upon the damp and forgotten autumn pavement. Dark crimson blood slowly pooled around the victim's head while distant sirens wailed through the foggy midnight air. He knelt beside the unfortunate corpse to examine the peculiar silver pocket watch clutched tightly within stiff fingers. Someone had carefully orchestrated this brutal crime beneath the flickering streetlamp to send a very chilling message.
