Thieves' Market by A. I. Bezzerides
A dark, fast-paced proletarian novel originally published in 1949, Thieves' Market was written out of the author's youthful experiences as a trucker carrying produce to the packing houses of California's Central Valley. Immigrant Nick Garcos, like his father before him, becomes an independent trucker, soon landing in the brutal and crooked underworld of the produce markets of San Francisco, Oakland, Stockton, and Los Angeles.
