Anne Austin: Born in 1895, Anne Austin began by writing romance novels about young women in the mid 1920's but soon turned her talents to producing a string of mysteries through the 1930's, some of which appeared as serials in newspapers.. Many of these mysteries feature as the detective "Bonnie" Dundee, Special Investigator for the District Attorney, including Murder Backstairs, The Avenging Parrot, Murder at Bridge, and One Drop of Blood. Several of her mysteries were translated into French, including Le Pigeon Noir and Le Crime Parfume. Despite her success as a novelist, Anne Austin disappears from the public record after the 1930's. Dorothy Bennett: Little information is available about Dorothy Bennett. It would appear that she grew up in Berkeley, California and probably went to the university there. Her mother was Mary Richardson Bennett, to whom she dedicated a murder mystery in the form of a poem entitled How Strange a Thing which was published in 1935, the same year as Murder Unleashed. H. Ashbrook: Harriette Cora Ashbrook (1898-1946) was the American author of thirteen mystery novels.
