What is the worst Ripper book you've ever read?

Collaborative effort?

There are also many curious things about the ms itself, different authors being involved, clear evidence of serious editing, and much else.

Very interesting! Maybe it was a sort of "round-robin" effort by two or more people taking turns writing it.

I am tempted to suggest The Daily Mail. Back when my parents read it, there was a tendency to regurgitate the press release for pretty much every Ripper book released, further thinning and confusing material already thinned from books of variable quality.
