I'm pretty sure 'The Wife' isn't rooted in reality. It might draw inspiration from various ideas and themes, but not from a specific true event or person.
I'm not certain as the title is so general. There could be many books out there with this kind of title or theme. It might be popular within a certain niche, like among people interested in family - related true stories, but without more details, it's hard to say if it has wide - spread popularity.
Definitely not. '1984' is a dystopian novel that was created from the imagination of the author to present a cautionary tale about totalitarianism and surveillance, not based on real events.
