Arthur Dent and Ford Prefect are trapped in Earth’s past. Fortunately for them an anomaly in time/space opens a portal to the twentieth century. Only it is just three days before the Vogon constructor fleet blows up the planet. They find themselves at a cricket game in England just as a spaceship lands and takes the trophy. The two run into Slartibartfast that guy who loves designing fjords and did Norway for Earth. He takes the two off the Earth in time. Slartibartfash is on a mission. He tells how long ago a planet called Krikket was enshrouded in a dust cloud and never saw the rest of the universe. One day a spaceship crashed and this alerted the Krikketers that there must be something out there. When they build their own ship and saw the universe they decided it had to go. So they started a genocidal war against the universe. When they were defeated their planet was put in a stasis bubble where once the universe ended they would find themselves alone. Only a rogue ship of their killer robots managed to survive and are gathering the key components to release Krikket. Now the gang has to save the universe.
The final book in the trilogy that later became five books. (We’ll get to those later.) This was another wacky and funny story that was a real treat to read. There are just fun stuff like the party that goes on forever and raids a whole planet to get drinks and snacks. Or the being that is out to get Arthur Dent because Dent has killed his many reincarnations such as a fly or raw oyster. Then there is the omnipotent being who’s life goal is to insult everybody who ever lived alphabetically. A fun book that ending a trilogy at the time on a high note.
