LA FEMME INFIDÈLE 
France - 1969
Charles Desvallées has good reasons to believe that his wife is cheating on him and hires a P.D. in order to prove himself right. Once he knows the lover is writer Victor Pégala, he drives to his apartment, calmly presents himself as the husband, starts a conversation and then kills him cold-bloodedly.
