Task: Question Generation
Input (English): Why does the flame go down? Lights in the London house are from fixtures with gas flames, and when you light one light, it reduces gas supply to the other lights in the house that are close by, and the light dims. Yet no one in the house has lit any other lights! And there are also footsteps overhead, from a nailed-closed attic. Neither of the two servants sees or hears either of these signs. Paula Anton (Ingrid Bergman) thinks she is losing her mind, just as she has lost the brooch her husband Gregory (Charles Boyer) gave her.Her new marriage is falling apart; she cannot go out lest she make another embarrassing scene. Is it the house, where Paula's aunt, a famous and beautiful concert singer, was murdered when the young Paula resided there? What does her new husband, who plays the piano beautifully, do for a living? Nothing. Why does he go out every night and leave her alone to fret and worry?Who is the man who sees them at unexpected times and places, a man we soon learn is Scotland Yard detective Brian Cameron (Joseph Cotton)? Cameron is curious about the unsolved murder of Aunt Alice Alquist, who looked a great deal like Paula does now -- a murder that defied the investigators.
