Best suspect book?

[Nemo]

Definitely Helena's recent work about George Chapman, "Jack the Ripper at last?"

I haven't actually read Tim Riordan's "Prince of Quacks" about Tumblety but I would think that's up there somewhere going by the reviews and comments about it

Hi all,

What does everyone think is the best JTR suspect book? A book that is careful and sticks to the facts and presents it's case through non-fantastical means and has a credible author.

In my opinion, I've always thought Robert House's book on Kosminski was the best one, mostly because (aside from the reasons I listed above), he doesn't say that he was JTR, but why he was considered the #1 sus pect at the time.
