The Woman in the Window is a psychological thriller novel by A. J. Finn, published in 2018. The story follows Dr. Anna Fox, an agoraphobic woman who spends her days in her New York City brownstone, watching old black-and-white movies and drinking too much wine.
One day, Anna witnesses a murder in the house across the street, but the police find no evidence of a crime and believe that Anna might have imagined it due to her heavy medication and alcohol use. Anna’s attempts to prove what she saw are further complicated by her strained relationships with her estranged husband and young daughter, who are living elsewhere.
As Anna becomes more and more desperate to uncover the truth, she begins to unravel a series of secrets that have been hidden in the seemingly idyllic neighborhood, including infidelity, mental illness, and a web of lies. But as she gets closer to the truth, Anna realizes that someone is watching her, and she may be in grave danger.
The novel is a gripping exploration of the nature of perception, trust, and reality, with plenty of twists and turns that keep the reader guessing until the very end.

One of the novel’s strengths is its main character, Anna Fox. Her struggles with agoraphobia, alcoholism, and the fallout from a traumatic event make her a sympathetic and relatable protagonist. Readers will root for her as she tries to uncover the truth about the murder she witnesses, even as her own perceptions and memories are called into question.
Finn’s writing is sharp and vivid, and he expertly builds suspense throughout the novel. His use of old black-and-white movies as a motif adds an extra layer of depth to the story, as Anna uses them as a way to escape her own reality and as a metaphor for the distorted perceptions that plague her.
While the novel’s ending may not be to everyone’s taste, it is undeniably a powerful and memorable conclusion that ties up the story’s loose ends while leaving the reader with much to ponder.
The Woman in the Window is a thrilling and well-crafted novel that is sure to satisfy fans of the genre. You can get a copy from Amazon here.
