The Spacemen's was a sanctuary, a rest club where in-coming pilots and crewmen could relax before leaving for another voyage. The rule that no females could pass its portals was strictly enforced. There she stood before a frantically gesticulating desk clerk, leaning on her faded green umbrella. To her publishers and her readers she might be Annabella C.
