Anne Boyce I had a question about the difference between the original radio series and the books. I had the great good fortune to run into Douglas Adams when he was doing a book signing in Fareham one Saturday, so I asked him the question. The answer, straight from the horse's mouth, was that the radio series grew 'organically', but that the books were written and he decided to make the story more 'structured'. If anyone else wants to know the answer then maybe you could include the question and answer as given?
