In the 1970s, a new "Ripper" theory surfaced. It involved Prince Albert Victor (nicknamed "Eddy"), son of the future Edward VII and grandson of Queen Victoria. Turns out, Eddy had been in serious trouble with his family during the summer and fall of 1888.
A few years before, Prince Eddy (also known as the "Duke of Clarence") allegedly fell in love with, and secretly married, an illiterate shop girl named Annie Crook. After she gave birth to a daughter, named Alice Margaret Crook, Annie hired a friend to help out as nursemaid. But that (according to the theory) was before the royal family (including Queen Victoria) learned of the Prince’s indiscretions. Since Eddy was next in line for the throne, after his father succeeded Queen Victoria, how could such a marriage ever be condoned?
Annie Crook (1868-1920) ultimately ended up in an insane asylum - allegedly put there (and lobotomized) by the Queen’s physician, Dr. William Gull. And her nursemaid friend, Mary Kelly, was the most brutally murdered of all the Ripper’s victims. The Prince himself was dead at 28, just days before his planned wedding to Princess Mary of Trek.
Was Mary Kelly a targeted, decreed murder? So says the late Stephen Knight who uncovered the story. So says Alan Moore in his graphic (definitely NOT for children) book From Hell.
