'Dear Boss - I keep on hearing the police have caught me but they won't fix me just yet.' Was Jack the Ripper an American, or had he lived in the United States? Did he commit any of the Ripper-style murders carried out in the U.S. in the late nineteenth and early twentieth centuries? Simon Webb's first non-fiction book about the Whitechapel killer re-tells the stories of the murders usually attributed to this mysterious figure, and re-examines the evidence surrounding a number of suspects with American connections.
