Q: You will be given a summary of a story. You need to create a question that can be answered from the story. You can create a question about characters, events, facts and beliefs, etc. Your question should be specific, try not to use pronouns instead of full names. As the stories are sometimes movie plots, they will contain actor names in parentheses. You should not use those names. Only use character names. Try to ask a question about all parts of the plot, not just the beginning.
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 evening, in a hansom cab. The city of 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 an illegitimate daughter living on the streets. 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 had gained notoriety as a place frequented by prostitutes and criminals.
