Rain hammered the dark windows as Detective Harmon slowly entered the old mansion, his sharp eyes scanning the bloodstained floor. The wealthy young heiress lay sprawled across the expensive ornate Persian rug, her lifeless fingers clutching a torn photograph tightly. Lightning flashed suddenly outside, briefly illuminating the elegant ballroom where society's finest had danced just hours before tragedy had struck. Officers had already cordoned off the entire property perimeter, though curious neighbors gathered at the gates with their eager speculation. The deceased woman's husband stood rigidly in the darkened corner, his face a mask of grief that seemed oddly rehearsed. Detective Harmon carefully noted the unmistakable smell of expensive whiskey lingering in the air despite the victim's pristine public reputation. Without warning, a terrified scream suddenly pierced through the mansion from upstairs, sending officers rushing up the grand spiral staircase.
