Thérèse Raquin (also The Adultress) is a 1953 French-Italian drama film directed by Marcel Carné and starring Simone Signoret, Raf Vallone and Jacques Duby.

Thérèse, an orphan, has been brought up by her widowed aunt in a dingy backstreet shop in Lyon and married to her sickly first cousin Camille.

The news of Camille's death gives his mother a stroke that leaves her speechless, cared for by Thérèse who warns Laurent to stay away and not attract police attention.

However there was another man asleep in Thérèse's compartment on the train and, when he sees the newspaper reports, comes down to Lyon and asks for half a million francs to stay silent.

Aware that Thérèse and Laurent might kill him rather than pay, he leaves a letter with the maid in his hotel, asking her to post it to the police if he does not return.
