while jeff is continuing his phone conversation, we see the object of his look. two pretty girls have appeared on the distant roof. they are smiling and talking, although we cannot hear their dialogue. each wears a terrycloth robe. with their backs to the camera, they take off the robes, slipping them down over their shoulders slowly. then, seductively, they turn -- revealing the full beauty of their tanned and bathing- suited bodies. it is almost as if they want to be noticed, the center of neighborhood attention. they at least have all of jeff's attention. then they spread the robes in front of them, and lie down on the roof, and out of sight. jeff seems a little disappointed. jeff's attention is now drawn to another feature of his backyard entertainment. the camera is now focused on the window of the small building where we earlier saw the girl behind the oscillating fan. loud ballet music is pouring from her open window. the girl, now dressed in dark and revealing leotard, and ballet slippers, has just turned away from a portable record player. she begins the first graceful movement of a modern ballet interpretation. the camera pans from the window of the dancing girl, to the window below. someone is reading the new york herald tribune. the paper lowers, and we see an elderly lady, in her late sixties. she is a faded, refined type. she looks up in the direction of the music and in a calm routine fashion adjusts the volume of her hearing aid. she resumes her reading. it is now mid-morning. the sun is shining. miss torso is practicing her dance to the sound of ballet music. pulling across to the far side of the street we see the hood and cab of a freight truck. the figure of stella is seen, looking up toward jeff's apartment, and arms outspread in a helpless gesture. doyle, who has appeared, at the street opening. the detective is surveying the front of the apartment building where thorwald lives. a paper seller behind him offers to sell him a paper. doyle isn't interested.
