A phenomenon across all formats, Douglas Adams' The Hitchhiker's Guide to the Galaxy has been a radio show, a television show, a move and a series of bestselling novels. The Hitchhiker's Guide to the Galaxy: The Trilogy of Four contains the first four parts of the cult classic 'trilogy': The Hitchhiker's Guide to the Galaxy, The Restaurant at the End of the Universe, Life, the Universe and Everything, and So Long, and Thanks for All the Fish.

The Hitchhiker's Guide to the Galaxy: One Thursday lunchtime the Earth gets demolished to make way for a hyperspace bypass. For Arthur, who has just had his house demolished, this is too much. Sadly, the weekend's just begun.

The Restaurant at the End of the Universe: When all issues of space, time, matter and the nature of being are resolved, only one question remains: Where shall we have dinner? The Restaurant at the End of the Universe provides the ultimate gastronomic experience and, for once, there is no morning after.

Life, the Universe and Everything: In consequence of a number of stunning catastrophes, Arthur Dent is surprised to find himself living in a hideously miserable cave on prehistoric Earth. And then, just as he thinks that things cannot possibly get any worse, they suddenly do.

So Long, and Thanks For All the Fish: Arthur Dent's sense of reality is in its dickiest state when he suddenly finds the girl of his dreams. They go in search of God's Final Message and, in a dramatic break with tradition, actually find it.

Douglas Adams created all the various and contradictory manifestations of The Hitchhiker's Guide to the Galaxy: radio, novels, TV, computer game, stage adaptations, comic book and bath towel.
