The grandfather clock in the foyer struck twelve, its chime echoing through the silent manor. Lady Ashworth lay crumpled at its base, a single silver dagger protruding from her back. A shattered crystal decanter bled ruby wine across the polished oak floorboards. Detective Harding knelt, noting the faint scent of jasmine clinging to the victim's velvet gown. The French doors stood ajar, letting in a cold draft that whispered through the curtains. From the study, a disembodied voice laughed, low and mocking, before falling quiet.
