Oh my stars and garters! Mr. Packer's guiding spheres must have gone into one whale of an inspirational orbit to produce this one. Archie Gamble, writer, is working on a television special based on astrology. His high priestess and chief nemesis is the obstreperous Mrs. Muckerman who does annoyingly accurate horoscopes and insists on having a set of ""Astro-twins"" for the show. Astro-twins are people born within minutes on the same day in the same latitudes. Mrs. Muckerman is out to prove that their lives maintain an astonishing similarity. She has cases to prove it. The only astro-twin who turns up turns out to be Archie's. He's one Neal Dana, psychologist, and his wife, Margaret, plans to spring the special on him as a surprise. But on the day that Archie and his wife, Dru, are to arrive, Margaret is killed (murdered?) during a fight with Neal's girlfriend. Neal hides the body and then tries to hide the fact in a plot that becomes as crisscrossed as a star chart. And then there's the suspicion that Archie might find himself in exactly the same circumstances. Do rely on Gemini, it's astronomically resourceful and the sky's the limit.
