‘The Woman in Cabin 10’: Movie vs. Book Differences

Comparison of 'The Woman in Cabin 10' Movie and Book

Ruth Ware's 2016 thriller novel 'The Woman in Cabin 10' has been adapted into a 2025 Netflix movie. The story follows Lo Blacklock, a journalist played by Keira Knightley, who embarks on a luxury yacht trip with a wealthy couple, Richard Bullmer and Anne Lyngstad.

The plot begins with Lo witnessing a disturbing event: a person falling over the yacht's side and blood on the divider between her balcony and cabin 10. However, when she reports this to the crew and passengers, they are skeptical since cabin 10 was supposedly empty and no one is missing.

While the initial setup is the same in both the book and the movie, significant differences emerge, including Lo's workplace and the ending. The adaptation stars Guy Pearce as Richard Bullmer and Lisa Loven Kongsli as Anne Lyngstad.

No one believes her, because cabin 10 was empty and no known passengers are missing.

Author's summary: A journalist's yacht trip turns deadly.
