The fog-choked marquee of the Gilded Harp gala held its last shrieking guest three minutes before the first scream erupted. Party guest and part-time investigator Elara Voss stumbled backward over a crushed champagne flute to spot the heiress’s cold form. The butler’s bloodied silver letter opener protruded from her silk sash as rain seeped through the terrace’s worn stone tiles. Veteran detective Miles Rainer burst through the glass double doors ready to unpack the estate’s decades of hidden dark secrets.
