Abstract
Prologue: The Echo of Guilt The storm lashed against the crumbling mansion, as if nature itself looked to reveal the horrors within. Beneath the flickering light of a dying chandelier, a body lay sprawled on the marble floor. The victim’s face was a mask of terror, eyes fixed on an empty space that seemed to hold its own chilling secrets. A clock chimed midnight, each toll reverberating like an accusation in the silence. In the corner, unnoticed, a single feather rested—a clue, or a cruel jest? Somewhere in the shadows, a figure watched, unseen, as the detective arrived. This was not the first crime, and it would not be the last.
