Borges, The Garden of Forking Paths

The short story, The Garden of Forking Paths, by Jorge Louis Borges is a fictional philosophical story used to illustrate the idea of an infinite, ever expanding labyrinth of time. The framework for this idea is based around a spy-espionage mystery where Dr. Yu Tsun, who is a German spy, needs to relay information to his commander about a British city that is hiding an arsenal. He decides that the best plan is to kill a man, Stephen Albert, who has the same name as the city, that way when the commander reads the news, he will understand the name of the town that needs to be bombed.
As his plan unfolds, he takes a train to the house where the man lives. There, upon meeting Stephen, he comes to learn that Stephen is a scholar who has been studying the life of his great grandfather, Ts’ui Pen. They begin a discourse about the theories of an endless book he wrote, which could also be considered an infinite labyrinth. They then discuss the ideas brought forth by this book, about time forking off into different histories, which can then later on meet again, or fork off into more and more paths.
At the end of the story, the detective, Richard Madden, arrives at the house. Yu Tsun shoots Stephen and is then arrested.
