Sam Ross was the pen name of Samuel Rosen, a Russian born writer who was brought to the U.S. by his parents, attended school, joined the army, served during World War II, and turned both his immigrant and war experiences into journalism, fiction, and screenplays. He was immediately successful, and later shared his valuable insights by teaching at UCLA. You Belong to Me is a wrong-side-of-the-tracks tale of a married man who gets involved with another woman while his wife is out of town and finds himself in all sorts of trouble. The backdrop for his descent into craziness and danger is Manhattan, and often Harlem, which rarely fails in literature to provide writers the tools they need to craft a picturesque tale. Ross takes his protagonist through jazz clubs and all the rest. The book appeared as a paperback original from Popular Library in 1955, and the top notch cover art is by Owen Kampen.
Well, technically I belong to Lester back there, but if you've got the money I'm available for lease.
