Jack the Ripper started his killings in the late 19th century in the slums of East London and most of his victims were prostitutes. I now live in the building where he killed his last victim (the building is now a dorm for LSE students). Tour guides stop right below my window to tell Jack the Ripper's story at least 6 times per day and seven days per week, so I have become some sort of expert on this serial killer. I am even considering doing these tours myself, seeing that I know three different versions of the story of how he killed the last prostitute.
