In Red Harvest, by Hammett, and The Life and Death of Great American Cities, by Jacobs, the theme of crime is very prevalent. Jacobs writes an intriguing explanation on cities and why crime is more frequent in certain areas rather than others. Hammett's piece is a mysterious story that revolves around crime and how the crime has wreaked havoc on the whole city of Personville. Both works showcased crime in two very different ways, but come to the same sorts of conclusions. Murder, gangs, and police who are either unable to do the whole job or corrupt through and through can lead to the destruction of a city.
