The Criminal Life of Archibaldo de la Cruz

At the police station, Archibaldo de la Cruz relates the story of the murder of a woman, and insists that he is the murderer. He's a talented potter with refined manners, but he's mentally unstable. One night, he says, he went to a casino and met a beautiful woman; after fighting with her lover, the woman crashed her car and Archibaldo offered to drive her home, where he murdered her. Archibaldo is engaged to a very pretty Catholic girl, but before he met her became fascinated with Lavinia, a beautiful and nice lady. He had invited her to his workshop one afternoon, and she seized the opportunity to make a joke to the nervous Archibaldo. Are these events the product of a compulsive, sexually-frustrated, and unstable mind?
