If you loved Quatre de l'espionnage, try Le Procès Paradine
Un pont entre un film que tu as déjà vu et un que peu de gens ont croisé. Voici ce qu'ils partagent, et ce que le second fait que le premier ne fait pas.
Ce qu'ils partagent
Both films are directed by Alfred Hitchcock, and they both carry the paranoid, slow burn mood tags, and they sit in Mystery / Romance territory. If that's the register that drew you to Quatre de l'espionnage, the second film will land in a comparable space — through a different lens.

What Le Procès Paradine is
London. Autumn. A chiming clock. A barrister becomes obsessed with the beautiful woman he defends in a poisoning case. His infatuation blinds him to the truth, and he begins to build a defense that threatens an innocent man. Hitchcock's courtroom drama is a study in moral compromise.
