This is, unfortunately, a prime example of what NOT to do when researching a subject. If this had been produced as a dissertation by one of my students I would have had no option but to fail it out right.
Yes, the author has done some research, but they have become so obsessed with their one point of view that they are unable, or unwilling, to see any alternative view, or contradictory information. The author picks a suspect (William Bury), declares his guilt and then finds bits and pieces of known information that might, if twisted, support his assertions. The true researcher is willing to look for information which disproves their theory, rather than looking for only the information that proves their thesis. Research which disproves a theory is just as valid as research with proves the theory, in many cases research which disproves a theory will be received with greater regard because of its honesty.
Mr Beadle sets out from the beginning to prove his thesis that William Bury is the Ripper and ignores completely any evidence that shows Bury was not his man. Bury has been mentioned as a suspect before, but has long since been ruled out.
Beadle's adaptation of general psychological theories and terms, as well as forensic and criminal psychological terminology, in order to add some kind of veritas to his argument is truly irritating, and so very, very wrong. Beadle's belief that Bury is the Ripper and the only true suspect is at the same obsessional level as fiction writer Patricia Cornwell's current Druitt fetish. His analysis of Bury is the worst kind of amateur rubbish I have ever encountered (and I've marked, graded and failed some trash during my career).
According to the author, Bury killed prostitutes whose names were the same as his mothers and sisters - good grief - lets be clear obsessional multiple murderers (like JtR, Bundy, etc) tend to obsess on one person, a mother, girlfriend, etc, and they go for looks rather than names. In all my experience I have yet to encounter, or hear of, an obsessional multiple murderer who has obsessed on more than one person (or has obsessed on a name or several names). How does the author cover the fact that the victims he lists all have different names, he doesn't. He simply justifies his theory by stating "Bury did ...." without reference to the slightest evidence to back up his statements.
Structurally, this book, if presented as a thesis or dissertation, would be thrown back at the author with a several choice words about layout and order. He jumps about all over the place. He starts talking about one thing, then gets distracted by something else, and forgets what he was talking about. I would suggest that he purchases a book in basis essay structure, and learns how to divide his work into organised sections.
How the author ever conned the publishers into putting this into print is beyond me - I can only assume they saw the "Jack the Ripper" in the title and saw the cash signs fly up in front of their eyes.
This is a book on the Ripper that should never cause the true Ripper researchers any bother, it is a bias irrelevance (harsh but true). If you are interested in seeing it, then I would suggest a visit to your local library to take a look at it, then you can decide if you waste your money on it, or to buy one of the more regarded books on the subject.
