A chilling autumn wind whipped through the darkened, sprawling estate grounds, carrying whispers of impending gloom and dread. The grand manor house stood silent and imposing under the pale, watchful eye of the distant, unforgiving moon. Detective Miles Corbin adjusted his trench coat, his gaze lingering on the solitary, illuminated window high above. He had received a cryptic call just hours ago, summoning him to this scene of unexpected, sudden tragedy. A uniformed officer waited patiently by the massive oak front door, a somber expression etched upon his tired, concerned face. They both understood that tonight, a life had been irrevocably extinguished, leaving behind a void and a puzzle unsolved.
