In the fourth installment of The Hitchhiker’s Guide to the Galaxy series, Arthur Dent finally comes home to Earth – somewhat inexplicably, given that it was destroyed by a Vogon Constructer Fleet. Very little has changed, and Arthur is more than happy to believe that his long, strange trip through time and space was simply a particularly alarming dream, but it seems the universe hasn’t finished with him yet. All the dolphins have vanished from the Earth’s oceans, and Arthur has been left a gift-wrapped fishbowl bearing the cryptic inscription ’So long, and thanks for all the fish.’ Along with Fenchurch, a woman with plenty of her own mysteries to solve, Arthur sets out to discover what it all means. Convinced that the secret lies in God’s Final Message to His Creation, they go in search of it.
