In 1888 a serial killer menaced the streets of the Whitechapel District in London. In America a serial killer was plotting the murder of hundreds on innocents amidst the backdrop of the 1893 World's Fair. The evidence presented indicates these two cases divided by an ocean have much more in common than ever before considered. Is it possible that the perpetrator of the London murders who was to become known as Jack the Ripper, and America's first serial killer, Dr. H. H. Holmes, were one in the same? Through case file evidence provided by the Metropolitan Police, Scotland Yard, and The British Archives, along with case file evidence evaluated by the Federal Bureau of Investigations (FBI), and the American Nation Archives, new revelations reflect there may have been a conspiracy to hide the identity of Jack the Ripper, further evidence shows he might have continued his murderous ways on the streets of Chicago after fleeing London.
