In this “locked room” mystery by Robert Arthur, a woman walks from her car into a snow-bound house and disappears. Her footsteps are visible going in, but there are none coming out. A search of the house shows no sign of the woman. The old man living in the house jokes with the attending policeman that if he had killed her, he would have had to “whisk her over a glass bridge in a flying saucer”. We learn at the end of the story that this is essentially true. Themes include isolation, past sins, deception, deductive reasoning, the “impossible” crime.
