Anna had two suspects in ‘The Woman in the House Across the Street From the Girl in the Window’

Anna’s everyday routine of sitting in her chair and drinking wine is interrupted when a single dad named Neil (Tom Riley) and his daughter Emma (Samsara Yett) move in across the street. She is first fascinated by her new neighbor and soon develops a crush. It ends when she learns he has a girlfriend named Lisa (Shelley Hennig).

Lisa rubs Anna the wrong way and one night witnesses her murder. But according to authorities, the murder never occurred. Sure of what she saw, Anna does some sleuthing and starts to suspect Neil after learning he was questioned about his wife’s death. His pregnant wife drowned in a lake.

Continuing the thread of evidence, Anna learns from the wife’s sister that Emma’s teacher also mysteriously died. Anna believes they had a relationship until Neil pushed her off a lighthouse during a school trip. Is Neil the killer?

In The Woman in the House, Anna certainly thinks so until Lisa’s body is found. The police also found the murder weapon, a sharpened painter’s palette knife. Not only does Anna still believe Neil is the killer, but she also questions if she is the culprit.

Audiences were likely fooled by the twists and turns in The Woman in the House and never suspected the real killer. In episode 7, Anna learns Buell (Cameron Britton) is living in her attic and has access to her art supplies. She sees him walking to Neil’s house with a hammer. Despite the rain, she goes to stop him and save Emma.

To her surprise, Buell is in the foyer with his throat slashed. He explains Neil’s mail got mixed with Anna’s and came to return it. If Buell is not the killer, then who is? Anna rushes to save Emma, believing the killer was Neil all along. But Anna finds Neil dead on the couch.

Anna turns and finds Emma holding a bloody kitchen knife. The killer of The Woman in the House was her. Emma explains adults always underestimate children, and Anna asks why she killed Lisa.

In The Woman in the House, Emma explains her killer motives that have audiences think she was a born murderer. She explains to Anna why she killed Lisa. In a flashback, Lisa rejects Emma’s request to buy school chocolate and tells her, “sugar is the worst thing you can put in your body.”

As Lisa is about to leave, Emma sneaks up behind her with a small kitchen knife and stabs her in the neck. Anna did see the murder. Emma cut up the body disposed of it in the forest to cover up her tracks. She then stole Anna’s painter’s knife to frame her.

But Anna is confused about how Neil did not hear anything. Emma explains he was in the bathroom with the water running to hide his ventriloquist act. In the end, Emma killed her father because his act was horrible. The biggest twist of all is when Emma reveals she killed her mother.

Emma was furious that her mother decided to have another baby without asking her permission. Wanting to stay an only child, Emma spent all summer sawing the support beam of the dock. She lured her mother to dock and made sure it collapsed. While The Woman in the House does not explain Emma’s teacher’s death, it can be assumed that Emma killed her as well.

The Woman in the House Across the Street From the Girl in the Window is available to stream on Netflix.
