Dr. Anna Fox lives alone in her New York City home, unable to leave due to severe agoraphobia caused by past trauma. She spends her time observing her neighbors from the safety of her window, creating stories about their lives while drowning her loneliness in prescription medication and alcohol. Her world changes when she fixates on the new family across the street—the Russells, who seem like the perfect family. However, one evening, Anna witnesses something shocking: Jane Russell, the friendly woman she had recently met, appears to be murdered in her home. When Anna reports the crime, the police arrive only to inform her that Jane Russell is very much alive—but she is not the same woman Anna met.

Confused and desperate to prove that she is not hallucinating, Anna begins investigating on her own, though her credibility is questioned due to her history of substance abuse and psychological instability. As she digs deeper into the mystery, her own past comes back to haunt her. Flashbacks reveal the tragic truth behind her agoraphobia—Anna and her family were involved in a devastating accident that left her riddled with guilt and trauma. These revelations intertwine with the present, further blurring the lines between reality and paranoia.

As Anna fights to unravel the mystery of Jane Russell’s disappearance, she becomes a target herself. She receives cryptic messages, experiences break-ins, and begins doubting her own mind. The novel’s tension builds as Anna’s world collapses, and just when she believes she has uncovered the truth, the final twist reveals a betrayal she never expected. The truth is darker than she imagined, and survival becomes her ultimate goal.

In The Woman in the Window, A.J. Finn masterfully crafts a psychological thriller that explores themes of grief, mental illness, and perception. With unreliable narration and a claustrophobic sense of suspense, the novel keeps readers hooked until its shocking conclusion, leaving them questioning how much they can trust what they see.
