Hi George
Well I don't think that James Maybrick was Jack the Ripper, and I do believe the "Diary" is a hoax. Nonetheless the issue of the Diary and how it came to be is interesting as is the original Maybrick case, when Florence Maybrick was found guilty of killing her husband James by arsenic poisoning in May 1889.
Her book,
Mrs. Maybrick's Own Story: My Lost Fifteen Years, is available
on line. It has always interested me that in the opening of the book on page 21, she calls the place where she lived "a suburb of Liverpool called Aigworth [sic]."
Best regards
Chris
