When she wakes up, she sees the body of dead woman, lying on the ground near her; a bearded man pulls a knife out of the woman's back. Nora reports this to the police in the hospital, who don't believe her when they find no evidence and think she's hallucinating.Later, at a cemetery, Nora meets a close friend of her aunt's, Laura Torrani (Valentina Cortese), who lives in the Piazza di Spagna. Laura plans to vacation soon and allows Nora to stay in her house for the remaining time of the vacation. Nora later explores Laura's closet and drawers and comes across newspaper clippings of articles on a serial killer dubbed the "Alphabet Killer" due to his having alphabetically killed people according to their surnames. The killer has already murdered victims whose last names begin with "A," "B," and "C," respectively. Nora also finds that the last victim Laura's sister, whom Nora had seen in a vision.

Nora receives help from Dr. Marcello, who takes her on a trip to various Roman tourist sites to calm her down as they become more romantically interested in each other.

Upon their return to the Craven house, they find Landini, who has been informed that they were inquiring about him. Investigative reporter Landini (Dante DiPaolo) has secretly been following them since he spotted Nora in the square.The reporter wrote about the murder story when it first broke, but he believes that the police would catch the wrong person if he reported the details of the crime. Landini's refusal to publish a report of the murder has put him in financial need. Nora decides to help Landini, but, as they tour Rome, they find no clues. Nora visits Landini's apartment the next day, finding clues that lead her to think that he is the murderer that and she is his next intended victim, but Landini appears to have committed suicide. The same day, Laura returns to Rome from her vacation while Nora and Marcello plan to go to America the following morning. From reading the newspaper, Nora learns that the body of a young woman was found, and she recognizes it as the murdered woman she saw on the night of her arrival in Italy. After identifying the victim's corpse at the morgue, Nora believes that she has witnessed the murder. Alone in the house that night, Nora notices that the study door is open. On entering, she sees a man rising uncomfortably from his chair. Nora recognizes him as the man who had stood over the dead body of the woman whose corpse she had seen after awakening from having been knocked unconscious upon her arrival in Italy. The man walks towards Nora but collapses to the floor, a knife in his back. Nora is then confronted by Laura who, enraged, confesses to the killings and explains that she stabbed her husband because of his attempts to turn her over to the police. Laura reveals that her desire to steal her sister's money compelled her to murder. Laura attempts to attack Nora, but Laura is suddenly shot dead by her husband.
