It all started innocently enough in New York's Gramercy Park district. Archie Gamble, a Gemini, is writing a TV special on astrology under the expert but irritating tutelage of Anna Muckermann. The show's success depends on Archie's finding a set of astro-twins - two persons born at the same moment in approximately the same vicinity. So far, no luck and no astro-twins. The studio deadline is scorching Archie's neck, and, as Ms. Muckermann kindly explains to his wife, the fault is in Archie's stars. His signs are bad. Nothing but trouble can be anticipated. As unpredictable Gemini would have it, Archie's own astro-twin steps forth in the shape of a mild-mannered psychologist, Neal Dana. Actually, Neal doesn't step forward. He's pushed, by his very attractive wife, who has her own personal reasons for wanting him out of the house a couple of nights a week. And what Neal and Archie are thrust into is a star-crossed pattern of events - and their violent and intertwined destinies will send panicked readers scurrying after their own horoscopes. Don't Rely on Gemini is one of the eeriest spellbinders in many a full moon.
