James L. Rubel (1895-1960) wrote nearly 50 novels, most of them westerns, under his own name and various pseudonyms, including “Mason Macrae,” for his UK-published titles). His westerns The Medico of Painted Springs, Prairie Stranger and Thunder Over the Prairie became a trilogy of movies in 1941. But he is perhaps best known today for his 1950, hard-boiled female PI novel No Business for a Lady.
