A brief novel by Guillermo Martinez. The early 1980s. The narrator (clearly an alter ego of Martinez, who also went on to study mathematics) is a teenager living in a small seaside town in the south of Buenos Aires province. He regards himself as the brightest person in town. One day, a new kid named Gustavo Roderer arrives in town, and the first time they met, Roderer beats him in chess. Then they meet in school, and the narrator increasingly becomes fascinated by Roderer, whom he sees as a sort of genius of otherworldly intelligence who has read everything. However, as time passes, and as the narrator goes to college to study math while Roderer stays at home, the reader slowly realizes that Roderer is hardly a genius, he's just a cultural omnivore, someone who has read a lot, but who lives holed up in a room in her mother's house, under increasingly difficult circumstances, dreaming in vain of creating a new system of philosophy that would overthrow the prevalent one. A good debut by Martinez, a writer working unusual themes.
