Hi all
Not fully related to the Ripper case but with some information that might amuse and inform is an essay I wrote about Irish-American writer Lafcadio Hearn (1850–1904) and the Japanese Tsunami which chronicles Hearn's relationship with Sir Arthur Diosy who had a black magic theory about the case. Go to "Lafcadio Hearn and the Japanese Tsunami: A Historical Essay"
Best regards
