The invite delivered to 6151 Richmond Street was short on details, only promising to celebrate 'the greatest artist of the century' and accompanied by a jewel-encrusted brooch - the whole package a brand of mysterious opulence that another Saturday night of gin rummy just can't match. Blanche Devereaux's passionate dalliances are as plentiful as hot Southern nights, and surely one can't be expected to remember all of one's suitors. But when the Girls disembark the party's ferry at a small Biscayne Bay island and meet their secretive host, the memories come flooding back: she a Radio City Rockette in her twenties, he the poor artist who could offer her nothing but his love. Fate drove them apart, but Declan, now a famous artist El Toro, professes that Blanche has always been his muse. Featured prominently in his artworks and central to El Toro's return to the apex of the art world, Blanche is thrilled to have been such an inspiring figure to this man. But looking around at a party filled with those who have made their livings off the artist's fame - his assistant, his art dealer, his greatest critic, and more - Dorothy isn't so sure they're welcome on the island after all. When a tropical storm knocks power out across the island, an optimistic Blanche proclaims that everyone looks better by candlelight anyway. But when Declan is found dead the next morning, all eyes are on her, his supposed muse of thirty-plus years. Trapped at the estate with the other guests - suspects all - the Girls must band together to find the true killer and get back to pleasant evenings of card games and cheesecake.
