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 just when he thinks things cannot possibly get any worse, they do. He discovers that not only is the Galaxy mind-bogglingly big and bewildering, but also that most of the things that happen in it are staggeringly unfair . . . The final part of the original Hitch Hiker's Guide trilogy confirms Douglas Adams as one of the most original and funniest of Britain's comic writers.
