Berkley Medallion PB No. 425-02626; Edition July 1974. Simak was a Grand Master of the SFWA and almost all of his novels and short stories are well worth the reading. The style is ruralist, an emphasis on country settings and peoples, usually sympathetic aliens, rarely horror or fantasy, a quiet frequently wry sense of humor. In this story, Earth after centuries of space travel has become the graveyard of the human race; a writer returns to Earth to compose a description, and discovers that there are forces abroad that seek to prevent him. Why?
