The body lay sprawled across the marble floor, blood pooling around. Detective Morgan arrived at the scene, his face etched with concern. Yellow crime scene tape fluttered in the cold autumn breeze. The victim's eyes stared vacantly at the ornate crystal chandelier. A single bullet hole marked the center of his chest. The mansion's silence was broken only by the detective's footsteps. "Time of death, approximately four hours ago," stated the coroner. Morgan knelt beside the body, studying the man's pale face. "Who found him?" he asked, pulling on latex examination gloves. The young officer consulted his notes with nervous, trembling hands. "His daughter called it in at precisely seven fifteen, sir." A sterling silver watch on the victim's wrist had stopped. Morgan noticed a crumpled note clutched in the dead hand. Carefully, he extracted the paper without disturbing potential evidence. Five words written in elegant script: "The debt is now paid."
