Collected together in The Hitchhiker's Guide to the Galaxy: The Trilogy of Four are the first four titles in Douglas Adams' wildly popular comedy science fiction series.

The Hitchhiker's Guide to the Galaxy

One Thursday lunchtime the Earth gets unexpectedly demolished to make way for a new hyperspace bypass. For Arthur Dent, who has only just had his house demolished that morning, this seems already to be rather a lot to cope with. Sadly, however, the weekend has only just begun. The Galaxy may offer a mind-boggling variety of ways to be blown up and/or insulted, but it's very hard to get a cup of tea.

The Restaurant at the End of the Universe

When all questions of space, time, matter and the nature of being have been 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 to worry about.

Life, the Universe and Everything

Following a number of stunning catastrophes, Arthur Dent is surprised to find himself living in a hideously miserable cave on prehistoric Earth. However, just as he thinks that things cannot get possibly worse, they suddenly do. An eddy in the space-time continuum lands him, Ford Prefect, and their flying sofa in the middle of the cricket ground at Lord's, just two days before the world is due to be destroyed by the Vogons. Escaping the end of the world for a second time, Arthur, Ford, and their old friend Slartibartfast embark (reluctantly) on a mission to save the whole galaxy from fanatical robots. Not bad for a man in his dressing gown.

So Long, and Thanks for All the Fish

There is a knack to flying. The knack lies in learning how to throw yourself at the ground and miss. It's not an easy thing to do, and Arthur Dent thinks he's the only human who's been able to master this nifty little trick - until he meets Fenchurch, the woman of his dreams. Fenchurch once realized how the world could be made a good and happy place. Unfortunately, she's forgotten. Convinced that the secret lies within God's Final Message to His Creation, they go in search of it. And, in a dramatic break with tradition, actually find it . . .
