First a legendary radio series, then a sequence of bestselling books, a television series, a computer game, a little-known Belgian progressive rock opera, a blockbuster movie, and finally this handsome hardback edition – primarily intended as a blunt object with which to bludgeon one's enemies – The Hitch Hiker's Guide to the Galaxy is one of the greatest fictional enterprises of the twentieth century.

Telling the long, circuitous and often inexplicable story of Arthur Dent, left homeless and rather annoyed after the Earth is destroyed in order to build a hyperspace expressway, this edition collects all five parts of the trilogy:· The Hitch Hiker's Guide to the Galaxy· The Restaurant at the End of the Universe· Life, the Universe and Everything· So Long and Thanks For All the Fish· Mostly Harmlessalong with a wealth of extra material prefaced and contextualised by Jem Roberts, the official biographer of Douglas Adams, to complete the canon.
