In 1947 the team of Will Oursler and Margaret Scott, writing under the pseudonym of "Gale Gallagher," created the first reasonably hard-boiled woman detective. Gale Gallagher, writing in the first-person, heads the Acme Detective Agency, which specializes in skip tracing. Gallagher is single, 5'5" tall, in her late twenties, attractive, and well-dressed. Her father was a New York City policeman, killed in the line of duty, who educated her in police lore as she grew up. She trained at the police academy, so she knows many policemen. She has a firearms license, but she doesn't usually carry a gun. She has a secretary and, in her private office, a Thomas Hart Benton painting that calms her. Her cases rarely turn too violent; however, she is knocked unconscious in I Found Him Dead (1947) but in Chord in Crimson (1949) she merely walks down dark alleys. From her clothes consciousness to her pastimes ("I do some of my best thinking in the tub"), Gallagher pre-dates the heroines of Grafton and Paretsky. Gale is interested in the jazz scene, frequenting clubs in New York and Baltimore where she sits solo at the bar. She dates a variety of men until she falls for painter Bart Crane at the end of I Found Him Dead (by far the better novel) and becomes his steady during the second novel, which is more in the English "murder-in-the-mansion" school. 8
