Premiering in the pages of Black Mask magazine prior to editor Joseph T. Shaw's run as editor, Tex of the Border Service battled crime on the 1920s U.S./Mexico border. Written by Black Mask's most prolific female author, Katherine Brocklebank, this collection contains all four installments in the Tex series-the only series in Black Mask history to feature a female lead character-along with two other hard-boiled detective stories by Brocklebank which also appeared in Black Mask.
