This revelation shifted the focus of the investigation and intensified the stakes for everyone in Nanny's orbit, particularly those who stood to benefit from or be harmed by the pregnancy.

Foreshadowing: Nanny's careful scheme to marry into higher society, revealed through flashbacks, suggests she viewed her pregnancy as a potential lever for social advancement.

Nanny was not the naive aspiring writer she appeared to be. Flashbacks revealed she had devised a calculated scheme to climb New York's social ladder. She moved from her uncle's home to live with a woman roommate, agreed to marry the roommate's brother as cover, and was secretly manipulating multiple people, including leveraging her affair with Brian, to position herself for social and financial gain.

Foreshadowing: Her ambitious pitch at the cocktail party and her quick manipulation of Peter to gain access to the Denver apartment hinted at a more calculating nature beneath the innocent facade.

Peter became a prime suspect because he was the last person to arrange access to the Denver apartment where Nanny died. Additionally, Lt. Bruce suspected Peter had been having an affair with Nanny, giving him both opportunity and motive. Peter evaded arrest and teamed up with the detective to find the real killer, proving his innocence by uncovering the truth.

Foreshadowing: The investigation's early focus on Peter stemmed from his professional relationship with Nanny and his role in facilitating her access to the apartment.

Brian Mullen, Lottie's quiet husband, confesses to Peter that he was Nanny's secret lover, though he swears he did not kill her.

No, Peter Denver was not actually having an affair with Nanny, despite the initial police suspicion. The alleged affair was part of the confusion surrounding the case. Nanny had manipulated her way into the Denvers' lives and apartment, but her real secret affair was with Brian Mullen, not Peter.

Foreshadowing: Nanny's request to use the apartment was presented innocently, but her true intentions involved the social circles surrounding the Denvers rather than a romantic connection to Peter himself.

As Lt. Bruce intensified the investigation and broadened the suspect pool, Lottie became a prime candidate. The discovery of Nanny's pregnancy and her secret affair with Brian provided strong motive for Lottie. Eventually, the pressure of the investigation and mounting evidence led Lottie to confess, revealing her crimes stemmed from jealousy and a desperate need to protect her marriage from scandal.

Foreshadowing: Lottie's icy personality and her intense focus on maintaining her image throughout the early investigation hinted at her willingness to commit extreme acts to preserve her reputation.

Lottie murdered Nanny because she discovered her husband Brian was having an affair with the young aspiring writer. Rather than risk the scandal destroying her marriage and public image, Lottie chose to eliminate Nanny entirely. Additionally, she feared Nanny would use the affair as leverage for blackmail, making murder seem like the only solution to protect her carefully constructed life.

Foreshadowing: Lottie's controlling nature and her visible efforts to manage her husband's public persona throughout the cocktail party suggested a woman deeply invested in maintaining a flawless marriage image.

The autopsy confirmation that Nanny was pregnant at the time of her death dramatically shifted the investigation. It added urgency and provided a critical new dimension to the case, as anyone who stood to benefit from or be harmed by the pregnancy became a potential suspect. The pregnancy also intensified the emotional weight of the murder, transforming it from a simple homicide into a case involving the death of an unborn child.

Foreshadowing: The growing web of suspects, including Brian's secret involvement, became more sinister once investigators learned of the pregnancy.
