Twice-widowed Jane Marsh ties the knot for the third time with longstanding fiancé Dale Capricorn. Jane's ready for a celebratory reception at her uber-trendy condo in downtown Denver with champagne toasts, fancy dress, and her family and dinner club friends. Everyone knows she and Dale's prettier and younger ex-wife Polly are "frenemies," but Jane starts fresh and asks Polly to cater the event. However, after the last guest leaves, Jane discovers the ex-wife dead—and Jane's the obvious suspect. If Jane doesn't find the real killer, her third marriage certainly won't be the charm.
