Rain hammered the glass as Inspector Mara Voss entered the silent ballroom where a billionaire lay beneath the fallen chandelier. His ruby cufflink gleamed beside one glove while champagne bubbles trembled in crystal and every guest avoided meeting her eyes. The orchestra stopped mid waltz leaving velvet chairs overturned programs scattered and a single black feather curling beside the corpse. A note inside the victim's pocket promised midnight justice yet the ink was fresh enough to stain Mara's careful fingertips. Then lights failed across the mansion and somewhere behind drawn curtains a second silver blade slid softly from its sheath.
