The Crying of Lot 49

This slender novel takes your ideas about conspiracies and turns them inside-out. Pynchon has the audacity -- or the cheek -- to posit not only the existence of one of the largest and most ominous conspiracies, real or fictional, of all time, but also its complete pointlessness. There's something darkly profound in here, a grimly comic insinuation about the way history's gears keep grinding, long after their original purposes have faded from memory.
