context: Peter Denver (Van Heflin) is a renowned Broadway producer attending a partyâhosted by the viciously haughty and celebrated actress Carlotta "Lottie" Marin (Ginger Rogers) and her quiet husband Brian Mullen (Reginald Gardiner)âwhen he meets Nancy "Nanny" Ordway (Peggy Ann Garner). Ordway is a seemingly naÃ¯ve, 20-year-old, aspiring writer, who hopes to make it big in New York. She convinces a reluctant Denver to let her use his apartment to work during the day, while his wife, Iris (Gene Tierney), also a famous actress, is away, but with her permission. After the Denvers return from the airport and find Nancy hanging dead in their bathroom, a variety of people Ordway has recently met in New York begin to reveal deeper and darker connections with her. Lt. Bruce (George Raft), the detective assigned to the case, soon discovers that this apparent suicide was in fact a homicide and believes that Denver, quickly suspected of having an affair with Ordway, is the murderer. Denver evades arrest and seeks clues to discover the real murderer; the case becomes cluttered when he and Lt. Bruce independently realize that Ordway's dealings in New York have not been as innocent as her superficial personality.
  Ordway had recently stayed with an artist roommate, whose deceived brother she evidently agreed to marry, while also staying for some time with her uncle. A series of flashbacks reveal that, all along the way, Ordway was craftily piecing together a scheme that would help her climb the social ladder and, later, conceal the identity of an apparent secret lover, while falsely implicating Denver; this mysterious romance is confirmed by an autopsy, which reveals that Ordway was pregnant at the time of her death. Everyone Ordway knew is suddenly a suspect in the murder case, including Lottie Marin and Brian Mullen, who live in the same apartment building as the Denvers. In the end, Mullen, who can no longer keep quiet to his friend Peter Denver, reveals that he was Ordway's secret lover, although he swears that he didn't kill her. Having bugged Mullen's apartment, Lt. Bruce barges in, charging Mullen with the homicide. Finally Marin admits she in fact strangled Ordway for having the affair with her husband, and set up the killing to look like a suicide.
