"[D]on't be such a damn fool as ever again to go to work for someone else. Start your own business," the 34-year-old Sinclair Lewis advised his friend Alfred Harcourt. "I'm going to write important books. You can publish them. Now let's go out to your house and start making plans" (p.xi). That business became the publishing house Harcourt, Brace, and Company, and the next year, in 1920, it published the book that made Lewis famous: Main Street. Thus began a decade-long partnership that lasted until Lewis became the first American to the win Nobel Prize in Literature. As the only volume of Lewis' letters, From Main Street to Stockholm was published in 1952, the year after he died, and collects together his correspondence with Harcourt's publishing house. Given their relationship the letters just as often pertain to business as they do Lewis' European travels and the politics of the literary world. While the reader may not close the book with a richer understanding of Lewis' psychology, they will have witnessed an iconoclast at work. Through these letters one follows Lewis through the "Big Five" and the public's response, from Main Street (1920) being declared the most monumental book of the century to Boston's District Attorney banning Elmer Gantry (1927) from the city.
