The Case of the Ersatz Earthquake

Los Angeles, fall 1988. For some time, a ""prognosticator"" named Sybil Divine has been exposing her apparent ability to predict earthquakes. She intends to extort money from L.A. Mayor Quail [sic] with her big scam. Everyone in town is convinced she can predict the big quake that will rock Southern California within the next half-century. Assistant Chief Rosa Morales knows better, as do Kate and George. They must prove it.
