Jack the Ripper reading list question

[truepenny]

If a person has read Donald Rumbelow's book on Jack the Ripper (variously published as The Complete Jack the Ripper and Jack the Ripper: The Complete Casebook), are there any other nonfiction Jack the Ripper books that one ought to read? I.e., has anything substantially new been said since Rumbelow? (And should I bother with anything pre-Rumbelow?)

Please note, I'm not asking what books about Jack the Ripper have been published since 1975; I can find that out for myself. I'm asking for recommendations about which, if any of them, to read.

I think I've mentioned this before, but "The Dance of the Gull-Catchers" is printed at the back of my copy of From Hell, and it's Moore writing a comic about the history of Ripperology and his own process of research. Not helpful re: this specific question, probably, but well worth reading in its own right, if you haven't already. ("You" being both michaeldthomas, who probably has, and truepenny, who may or may not have.)

Yes, I have. :-)

Yes. I need to bite the bullet and buy From Hell.

I wasn't all that fond of the actual comic, but much of that was for personal-mileage reasons. Certainly Moore did his research. (It's worth getting the version that has his annotations at the back, if your interest is at all scholarly; he extensively footnotes where he got all of his details from.)
