Certified male Casson Ferguson plays the title character in Alias Mary Brown. Left in reduced circumstances after his parents are driven to their deaths by an insensitve family, Ferguson takes revenge by robbing that family's household. To cover his tracks, he disguises himself as a woman (rather convincingly, if we can judge by the film's contemporary reviews). After a series of exciting adventures and hairbreadth escapes, Ferguson reclaims his manhood and falls in love with pretty Pauline Starke. Alias Mary Brown was based on a story by E. Magnus Ingleton, a female author (we think).
