The old mansion creaked under the weight of decades, its shadows concealing secrets that Detective Sarah Chen knew all too well. Wind rattled through broken windowpanes as forensics worked silently around the body, careful not to disturb any potential evidence nearby. The victim lay sprawled across antique Persian carpets, one hand clutching a silver locket that seemed oddly familiar to the detective. Blood had spread in elaborate patterns across the expensive fabric, telling a story of violence that had unfolded just hours before. Detective Chen crouched beside the corpse, noting the victim's manicured nails, designer clothes, and the strange symbol carved into her palm.
