Just about all of the evidence collected by the Metropolitan Police (London, that is) has been destroyed. What is left is a mass of circumstantial evidence that can be used to prove a wide range of suspects. A lot depends on whether you are prepared to bnelieve that a bunch of prsotitutes gathered enough evidence to blackmail the Royal Family through Prince Albert Victor, Duke of Clarence & Avon (then second in line to the throne - eldest son of the Prince of Wales, who became King Edward VII) Most of the evidence comes via Joseph Sickert, Walter's son, and relies on hearsay, and "remembering" what his father had told him.

As circumstantial evidence, it is pretty powerful stuff - but there is almost no hard evidence to support it.

If you offered it to me as an essay for my course on the Victorian Underworld, you'd get pretty low marks!


EDIT see The Ripper and the Royals, Melvyn Fairclough - (1992)
