This week the ladies travel through time ... Sadly, no DeLorean but they did stumble upon a massive tragedy... Jack The Ripper. Jack the Ripper was an unidentified serial killer active in the largely impoverished areas in and around the Whitechapel district of London in 1888. In both the criminal case files and contemporary journalistic accounts, the killer was called the Whitechapel Murderer and Leather Apron.
