Pacto con el Diablo (o el socio, Mr. Davis)
Juan is summoned by Goldenberg to offer him a job in the cheap business. To get away from him, Pardo evades his proposals justifying himself by saying that he must consult with his partner; who, in reality, does not exist. As the story progresses we can see how this partner, who is called Mr. Davis, takes on a life of his own inside Juan's mind.
