"La muerte y la brújula" is a short story by the Argentine writer and poet Jorge Luis Borges. Lönnrot is a famous detective in an unnamed city that may or may not be Buenos Aires. When a rabbi is killed in his hotel room on December 3, the case is assigned to him. Based on a cryptic message on the rabbi's typewriter - "The first letter of the name was pronounced" - Lönnrot realizes that the murder was not accidental. He combines this with the tetragrammaton, the unspeakable four-digit name of God, and with his criminal arch enemy Red Scarlet Fever.
