A moist little nothing, less than nothing as a mystery, about brother and sister Francesca and Nikki who spend time with their socialite heiress mother at Villa Belsola (no, that's not in Italy -- it's in Tuxedo Park, N.Y.) where they lose mother to a watery grave -- their father died in an accident too -- after she has remarried and Nikki feels guilty for months and years. . . . It's really for the gothic market and even at that, no more than an eyelash curler.
