There is a blurry edge in all detective work that, as Borges too competently demonstrates, skirts a zig-zag threshold between apophenia and the truly canny connection of events that only appear, superficially, to be disconnected. In the name of a method that is closer to invocation than criticism, a reckless detective might refrain from determining exactly where an act of decryption lies on the ugly terrain of legitimacy and, proffering sanity as the stake, live up to the problem as it stands.
