Co-authoring a collection of detective stories with Grace Isobel Colborn (1869-1948) was Auguste Groner (1850-1929). Joe Miller, a detective, served as the show's main character.Detective Joseph Muller of the Imperial Austrian police's Secret Service. He is very different from other well-known detectives in terms of personality. Muller is a small, weak, unremarkable man who exudes great humility in his temperament. The official rank of Muller is not much higher than that of a police officer. However, he consults with kings and council members, and the police department fully understands what a treasure he has in him.Joseph Muller's persona is an odd amalgam. He is a human bloodhound, the kindest man in the world. When the entire government of a top-notch police department appears incapable of uncovering anything, he will locate his victim. Even though it is a farce, Muller preserves its honor.Muller's working style, his perception of himself as merely a humble member of the Department, and the humor of acting by "official orders" when the Department is carrying out his instructions are all accurately portrayed by the author.
