The old mansion creaked beneath the weight of heavy rain. Detective Sarah Mills wiped fog from her tired, weary eyes. A body lay sprawled across marble steps inside the house. Blood streaked the white stone like ribbons of dark paint. Lightning flashed through tall windows, illuminating the grotesque scene below. The victim's hand still clutched a crumpled note in death. Sarah pulled latex gloves over her cold, trembling fingers slowly. This would be the third murder case this month alone. The killer was escalating, growing bolder with each new victim. Thunder rolled overhead as Sarah knelt beside the corpse.
