Query: The ultimative answer of Life, the Universe and Everything.

I first bought this book in London in 1986, at that time it was "A Thrilogy in four Parts" - since I've been lost in the world of our friends: Arthur, Ford Prefect, Trillian and Zaphod ! The book is zani humor, wellwritten and very philosifical in a satirical way. The best book I've ever read - but it's heavy stuff to read in bed !!!
