Thomas Ruggles Pynchon, Jr. is an American writer based in New York City, noted for his dense and complex works of fiction. Hailing from Long Island, Pynchon spent two years in the United States Navy and earned an English degree from Cornell University. After publishing several short stories in the late 1950s and early 1960s, he began composing the novels for which he is best known today: V. (1963), The Crying of Lot 49 (1966), Gravity's Rainbow (1973), Vineland (1990), Mason & Dixon (1997), and Against the Day (2006).

Pynchon is regarded by many readers and critics as one of the finest contemporary authors. He is a MacArthur Fellow and a recipient of the National Book Award, and is regularly cited as a contender for the Nobel Prize in Literature. Both his fiction and non-fiction writings encompass a vast array of subject matter, styles, and themes, including (but not limited to) the fields of history, science and mathematics. Pynchon is also known for his avoidance of personal publicity: very few photographs of him have ever been published, and rumours about his location and identity have been circulated since the 1960's.

Suffused with rich satire, chaotic brilliance, verbal turbulence and wild humor, The Crying of Lot 49 opens as Oedipa Maas discovers that she has been made executrix of a former lover's estate. The performance of her duties sets her on a strange trail of detection, in which bizarre characters crowd in to help or confuse her. But gradually, death, drugs, madness and marriage combine to leave Oedipa in isolation on the threshold of revelation, awaiting the Crying of Lot 49.
