Arthur has been living in a cave on prehistoric earth, almost completely alone, for the last four years... but it feels like two million. Suddenly, Ford rocks up, followed by a chesterfield sofa that just so happens to be going their way... anywhere but Arthur’s prehistoric cave is preferable. And so they wind up at Lord’s Cricket ground, four days before the scheduled destruction of the Earth. At Lords, they encounter Slartibartfast and a collection of vicious, cricket playing robots. Slartibartfast spirits them in his Bistro Mathematics powered spacecraft, to fill them in on the latest danger to the universe... the warriors of the planet Krikkit. The Krikkit warriors are travelling round, collecting seemingly innocuous artifacts with the deadly intention of releasing their masters.
