Arthur Dent after traveling the galaxy discovers that Earth still exists. He goes back to find the planet continuing on as if nothing happened. Everyone thinks the Vogon fleet was some CIA mind control experiment. There are two things though that changed. One is all the dolphins disappeared. The second is Arthur finds his house that was demolished is still standing. Along the way he meets a woman name Fenchurch. Fenchurch had a mental breakdown after the event and feels she knew something important. Their quest takes them to California and a man named Wonko the Sane who knows about the dolphins saving Earth. He decided that all of society is insane after reading the instructions posted on a toothpick box on how to use a toothpick. The two eventually meet up with Ford Prefect and hitch a ride on a passing spaceship to a planet that has God’s final message to the universe.
So the trilogy was so successful it would obviously get a fourth book. Back in the first it was established that the doIphins were the second most intelligent species on Earth. Apparently they managed to save the planet. There final message being the title. I think this is my favorite of the whole series. It takes place mostly on Earth and has some very funny observations on the planet. It also has a beautiful love story that Adams gave Dent. Well needless to say they do get off the planet and find God’s final message. Written in fiery letters on a planet that is a tourist trap. The message is pure Adams and was a very satisfying ending to the book.
