"Humor is next to Godliness." ― Sinclair Lewis, Mantrap To create Mantrap (1926), Sinclair Lewis adapted journals his brother Claude kept while the two traveled in Canada two years before the book appeared. In it, the author created the story of New York lawyer Ralph Prescott's journey into the Saskatchewan territory and of his adventures there. Two separate films, Mantrap (1926) and Untamed (1940), both of which were based on the story, were produced.
