The November rain lashed Blackthorn Manor’s slated windows as the annual winter charity gala wound slow to an uncertain halt. The young event coordinator ducked into the locked library to retrieve a donated vintage wine bottle for the final guests. Her scuffed leather boot slid in something sticky and warm that seeped through her thin threadbare wool ankle sock cuffs. She fumbled for the brass light switch by the door and gasped at the grim sight sprawled across the faded rugs. The mansion’s reclusive billionaire owner Emery Voss lay stone still an ornate letter opener jutted deep from his bloodied temple. None of the remaining party guests had noted his sudden absence through the last three chaotic raucous holiday bingo games.
