The story concerns a businessman from Milan, sent to a small town in Sicily to finalize a land deal that would allow his company to open a branch in the south. But the journey is plagued with difficulties from the beginning: his train breaks down and he is late arriving in the town, only to find that his contact there has been shot dead. From there, he wanders from one hostile encounter to another.
The narrative is in the first person, and there are hints that the narrator is creating some of the hostility himself, through his manner and attitude, And when the obstacles to his mission seem insurmountable, he remains in the town, courting hatred and danger, well beyond any reasonable time, despite insults and injuries.
The text is very detailed, evoking the claustrophobic Sicilian town vividly. The story is told clearly, though without a lot of forward motion, and I was pulled right along to the end. A major theme and characteristic element of the story (and this is hardly a spoiler) is that the "transaction" of the title never happens. The ending is, in fact, quite puzzling, leaving the reader to decide if the narrator is suicidal, infatuated, or perhaps insane.
