Aaron Marc Stein

Aaron Marc Stein, who used the pen name George Bagby, was an American novelist who specialized in mystery fiction. Bagby's focus was on police investigators, especially the fictional Inspector Schmidt, Chief of Homicide for the New York Police Department.

A number of his novels have been translated into other languages, including German, French, and Spanish.
