Between 1930 and 1936, Steinbeck and Ricketts became close friends. Steinbeck's wife began working at the lab as secretary-bookkeeper. Steinbeck helped on an informal basis. They formed a common bond based on their love of music and art, and John learned biology and Ricketts' ecological philosophy. When Steinbeck became emotionally upset, Ricketts sometimes played music for him. Steinbeck's first novel, "", published in 1929, is loosely based on the life and death of privateer Henry Morgan. It centers on Morgan's assault and sacking of the city of Panama, sometimes referred to as the "Cup of Gold", and on the women, brighter than the sun, who were said to be found there. Between 1930 and 1933, Steinbeck produced three shorter works. "The Pastures of Heaven", published in 1932, consists of twelve interconnected stories about a valley near Monterey, which was discovered by a Spanish corporal while chasing runaway Indian slaves. In 1933 Steinbeck published "The Red Pony", a 100-page, four-chapter story weaving in memories of Steinbeck's childhood. "To a God Unknown", named after a Vedic hymn, follows the life of a homesteader and his family in California, depicting a character with a primal and pagan worship of the land he works. Although he had not achieved the status of a well-known writer, he never doubted that he would achieve greatness. Steinbeck achieved his first critical success with "Tortilla Flat" (1935), a novel set in post-war Monterey, California, that won the California Commonwealth Club's Gold Medal. It portrays the adventures of a group of classless and usually homeless young men in Monterey after World War I, just before U.S. prohibition. They are portrayed in ironic comparison to mythic knights on a quest and reject nearly all the standard mores of American society in enjoyment of a dissolute life devoted to wine, lust, camaraderie and petty theft. In presenting the 1962 Nobel Prize to Steinbeck, the Swedish Academy cited "spicy and comic tales about a gang of "paisanos", asocial individuals who, in their wild revels, are almost caricatures of King Arthur's Knights of the Round Table. It has been said that in the United States this book came as a welcome antidote to the gloom of the then prevailing depression." "Tortilla Flat" was adapted as a 1942 film of the same name, starring Spencer Tracy, Hedy Lamarr and John Garfield, a friend of Steinbeck.
