Every version of In Secret — the books & films, compared across media.
Émile Zola's Thérèse Raquin planted a story that refuses to stay in one medium: a woman trapped in a suffocating marriage, a forbidden passion, and the guilt that follows. Set in the grimy backstreets of Paris, it turns on lust, adultery, and psychological ruin. That premise has drawn filmmakers across genres, giving the same dark core radically different forms on screen.
Yes. In Secret is adapted from Thérèse Raquin, Émile Zola's naturalist novel about adultery and guilt set in nineteenth-century Paris. The film follows the same core characters and premise.
There are three versions here: Zola's original novel Thérèse Raquin, the 2014 film In Secret, and the 2009 film Thirst, which takes the story in a horror direction.
In Secret (2014) is the most direct screen version of the story. Thérèse Raquin is Zola's original novel. Thirst (2009) takes the material into horror territory for viewers who want a genre departure.
