Goodbye Gemini (aka Twinsanity) is a 1970 thriller directed by Alan Gibson from the novel Ask Agamemnon by Jenni Hall. Jacki (Geeson) and Julian (Potter) Dewar, a pair of fraternal twins, arrive via bus to London; they are home from university on Spring break, and their father is in Mexico on business. The twins quickly set about mindlessly indulging themselves in the pleasures afforded to them by their father's estate, much to the chagrin of their put-upon housekeeper, Mrs. McLaren. When Mrs. McLaren threatens to upset their carefree life by imposing order upon it, they trip her down the stairs and stage it as an accident. Now free of "adult" supervision, Jacki and Julian launch themselves into London's underground party scene, clubbing at strip bars, accompanied by Jacki's teddy bear, Agamemnon, whom the twins address as a father figure. At one such club the pair encounter Clive, a small-time pimp who makes his way in the world by ingratiating himself with the wealthy and well-connected.
