Plot

The Mystery of a Hansom Cab takes place in Melbourne, Australia, and involves an investigation into a homicide, after a corpse is discovered in the early hours, in a hansom cab. Melbourne plays a significant role in the plot and, as the author describes, "Over all the great city hung a cloud of smoke like a pall. The killer's identity is not as significant a revelation in the story as are the roles of the influential and secretive Frettlby family, and their secret: they have a daughter living on the streets, and the woman everyone assumes is their daughter is illegitimate. The class divide between Melbourne's wealthy and less fortunate is addressed throughout the plot.
The protagonist in the novel is a policeman named Detective Gorby, who is given the task of solving the murder. As Hume describes the character's investigative skills, "He looked keenly round the room, and his estimate of the dead man's character was formed at once." The author commented in a later introduction, "All of the scenes in the book, especially the slums, are described from personal observation; and I passed a great many nights in Little Bourke Street, gathering material". At this time, the street was notorious as a place frequented by prostitutes and criminals.
