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.
There is a short story by Jorge Luis Borges which details an elaborate game of geometrical entrapment. The game is at once a temporal and spatio-cartographic one. It is played over a period of four months, on the fourth of each month, across a series of cardinal coordinates: a hotel in the North, a paint factory in the West, a tavern in the East, and an abandoned villa in the water-logged southern outskirts of the story’s unidentified city.
