, 8, 9, 10, I 1 and 12 of the radio series. These episodes of "The Hitchhiker's Guide to the Galaxy," you will remember, had already been incorporated in revised form in the book called The Restaurant at the End of the Universe. At this point I went to America to write a film screenplay which was completely inconsistent with most of what has gone on so far, and since that film was then delayed in the making (a rumor currently has it that filming will start shortly before the Last Trump), I wrote a fourth and last book in the trilogy, So Long, and Thanks for All the Fish. This was published in Britain and the USA in the fall of 1984 and it effectively contradicted everything to date, up to and including itself. As if this all were not enough I wrote a computer game for Infocom called The Hitchhiker's Guide to the Galaxy, which bore only fleeting resemblances to anything that had previously gone under that title, and in collaboration with Geoffrey Perkins assembled The Hitchhiker s Guide to the Galaxy: The Original Radio Scripts (published in England and the USA in 1985). Now this was an interesting venture. The book is, as the title suggests, a collection of all the radio scripts, as broadcast, and it is therefore the only example of one Hitchhiker publication accurately and consistently reflecting another. I feel a little uncomfortable with this-which is why the introduction to that book was written after the final and definitive one you are now reading and, of course, flatly contradicts it. People often ask me how they can leave the planet, so I have prepared some brief notes. How to Leave the Planet I. Phone NASA. Their phone number is (13) 483 3111. Explain that it's very important that you get away as soon as possible. 2. If they do not cooperate, phone any friend you may have in the White House-(202) 456 1414-to have a word on your behalf with the guys at NASA. 3. If you don't have any friends in the White House, phone the Kremlin (ask the overseas operator for 010 095 295 9051). They don't have any friends there either (at least, none to speak of), but they do seem to have a little influence, so you may as well try. 4. If that also fails, phone the Pope for guidance. His telephone number is 011 39 6 6982, and I gather his switchboard is infallible. 5. If all these attempts fail, flag down a passing flying saucer and explain that de's vitally important you get away before your phone bill arrives.

Orbiting this at a distance of roughly ninety-two million miles is an utterly insignificant little blue green planet whose ape-descended life forms are so amazingly primitive that they still think digital watches are a pretty neat idea. This planet has-or rather had-a problem, which was this: most of the people on it were unhappy for pretty much of the time. Many solutions were suggested for this problem, but most of these were largely concerned with the movements of small green pieces of paper, which is odd because on the whole it wasn't the small green pieces of paper that were unhappy. And so the problem remained; lots of the people were mean, and most of them were miserable, even the ones with digital watches. Many were increasingly of the opinion that they'd all made a big mistake in coming down from the trees in the first place. And some said that even the trees had been a bad move, and that no one should ever have left the oceans. And then, one Thursday, nearly two thousand years after one man had been nailed to a tree for saying how great it would be to be nice to people for a change, one girl sitting on her own in a small cafe in Rickmansworth suddenly realized what it was that had been going wrong all this time, and she finally knew how the world could be made a good and happy place. This time it was right, it would work, and no one would have to get nailed to anything. Sadly, however, before she could get to a phone to tell anyone about it, a terribly stupid catastrophe occurred, and the idea was lost forever. This is not her story. But it is the story of that terrible stupid catastrophe and some of its consequences. It is also the story of a book, a book called The Hitch Hiker's Guide to the Galaxy-not an Earth book, never published on Earth, and until the terrible catastrophe occurred, never seen or heard of by any Earthman. Nevertheless, a wholly remarkable book. In fact it was probably the most remarkable book ever to come out of the great publishing houses of Ursa Minor-of which no Earthman had ever heard either. Not only is it a wholly remarkable book, it is also a highly successful one-more popular than the Celestial Home Care Omnibus, better selling than Fifty More Things to do in Zero Gravity, and more controversial than Oolon Colluphid's trilogy of philosophical blockbusters Where God Went Wrong, Some More of God's Greatest Mistakes and Who is this God Person Anyway? In many of the more relaxed civilizations on the Outer Eastern Rim of the Galaxy, the Hitch Hiker's Guide has already supplanted the great Encyclopedia Galactica as the standard repository of all knowledge and wisdom, for though it has many omissions and contains much that is apocryphal, or at least wildly inaccurate, it scores over the older, more pedestrian work in two important respects. First, it is slightly cheaper; and secondly it has the words DON'T PANIC inscribed in large friendly letters on its cover. But the story of this terrible, stupid Thursday, the story of its extraordinary consequences, and the story of how these consequences are inextricably intertwined with this remarkable book begins very simply. It begins with a house. Chapter 1 The house stood on a slight rise just on the edge of the village. It stood on its own and looked over a broad spread of West Country farmland. Not a remarkable house by any means-it was about thirty years old, squattish, squarish, made of brick, and had four windows set in the front of a size and proportion which more or less exactly failed to please the eye. The only person for whom the house was in any way special was Arthur Dent, and that was only because it happened to be the one he lived in. He had lived in it for about three years, ever since he had moved out of London because it made him nervous and irritable. He was about thirty as well, dark haired and never quite at ease with himself. The thing that used to worry him most was the fact that people always used to ask him what he was looking so worried about. He worked in local radio which he always used to tell his friends was a lot more interesting than they probably thought. It was, too-most of his friends worked in advertising. It hadn't properly registered with Arthur that the council wanted to knock down his house and build an bypass instead. At eight o'clock on Thursday morning Arthur didn't feel very good. He woke up blearily, got up, wandered blearily round his room, opened a window, saw a
