he first fruit of the collaboration of Borges and his long-time friend Bioy-Casares, Six Problems for Don Isidro Parodi appeared originally under the pseudonym of H. Bustos Domecq. "Bugsy's" prose style is not quite the style of either of the collaborators, but in this volume, at least, "he never got out of hand," as Borges complained he did later. In the first story, Parodi, who is himself in jail for homicide, is visited by a young man who seeks his help in solving a particularly baffling murder. In the second story, a killing takes place aboard an express train. One of the characters is a writer named Gervasio Montenegro, whom the discerning reader will identify as author of the book's expressive foreword. In "Tadeo Limardo's Victim," a murdered man prepares for his own death. "Tai An's Long Search" is a variation on Poe's "The Purloined Letter." In "Free Will and the Commendatore," a cuckold takes elaborate and invisible revenge.
