The Hitchhiker’s Guide to the Galaxy

The Hitchhiker’s Guide to the Galaxy, the first book (1979) in the highly popular series of comic science fiction novels by British writer Douglas Adams. The saga mocks modern society with humour and cynicism and has as its hero a hapless, deeply ordinary Englishman (Arthur Dent) who unexpectedly finds himself adrift in a universe characterized by randomness and absurdity.

Summary

Arthur Dent, whose house is about to be demolished for a planned road bypass, is lying down in front of a bulldozer when his friend Ford Prefect arrives and tells him that it is imperative that they go to the pub immediately. There Ford explains that he is actually from a planet near Betelgeuse and that another alien species, the Vogons, are about to destroy the Earth to make space for a hyperspatial express route. Meanwhile, Zaphod Beeblebrox, president of the Galaxy, and his human female friend Trillian steal the Heart of Gold spaceship. Ford and Arthur hitch a ride on a Vogon destructor ship, and Ford lends Arthur the electronic guidebook The Hitchhiker’s Guide to the Galaxy and gives him a Babel fish to stick in his ear to translate alien speech. The Vogon ship captain has Ford and Arthur ejected into space, but the Heart of Gold, which has an Infinite Improbability Drive, picks them up 29 seconds later. The drive makes it possible to traverse interstellar space almost instantly but also causes Ford to (briefly) turn into a penguin.

Zaphod sends his depressive robot, Marvin, to escort the hitchhikers to the bridge. Later that night, the Heart of Gold reaches its destination—the legendary planet Magrathea, which in the past built planets to order for wealthy customers but later disappeared. However, Magrathea, after sending a message that it is closed for business, fires missiles at the Heart of Gold. The ship’s computer is unable to take evasive action, but Arthur engages the Infinite Improbability Drive, and the missiles turn into a sperm whale and a bowl of petunias; both fall to the planet’s surface. Everything seems fine, except that Trillian’s pet mice, Benjy and Frankie, escape their cage.

On Magrathea, Zaphod, Trillian, and Ford explore the planet’s tunnels, leaving Marvin and Arthur to guard the entrance. Arthur encounters an elderly native of the planet, who introduces himself as Slartibartfast and explains that the populace is not dead but were sleeping until the economy improved. They are now engaged in building a second Earth, having been commissioned by mice, which are really hyperintelligent pandimensional beings, to build the first Earth. These beings had built a supercomputer, Deep Thought, to determine the answer to life, the universe, and everything. After a period of 7.5 million years, the computer declared the answer to be 42. The computer designed a more powerful computer, Earth, to find the question to which 42 is the answer. Earth had nearly completed its calculations when the Vogons destroyed it. Slartibartfast brings Arthur to meet the mice who commissioned the building of Earth, and they prove to be Benjy and Frankie. Zaphod and Ford suggest that Arthur may have some ideas about the Question, as his “brain was an organic part” of Earth, and Benjy and Frankie decide that they will buy Arthur’s brain and chop it up to look for their answer.

Arthur, Ford, Zaphod, and Trillian are saved by the arrival of the galactic police to arrest Zaphod for the theft of the Heart of Gold. Marvin depresses the computer running the ship and life systems for the police into committing suicide, and the five travelers all escape to the Heart of Gold, after which they head toward the Restaurant at the End of the Universe.
