Fog clung to the cobblestones as Detective Larkin entered the manor, his flashlight trembling in the stormy night silence alone. Inside, a chandelier cast eerie light on the grand hall, where a crumpled figure lay beside shattered glass in silence. Larkin knelt, noting the victim's blood-stained cufflink, a single rose petal, and a faint perfume lingering in the musty air. A muffled sob echoed from the library, where an elegant woman in black gloves traced trembling fingers over a portrait. Larkin sensed the murderer watched, heart pounding, as midnight struck, sealing secrets within these ancient, whispering walls of the estate.
