What is the Setting of the meteor by john Wyndham?

The story is initially set at Mr. Fontain's residence and the story then shifts onto the planet forta where we learn about an alien and his specoes. After giving a description of forta the author again shifts the story back to earth where an investigation is taking place of a myserious object which appeared from the sky. This process is repeated 6 times when the story finally ends in Mr. Fontain's out house.
