Query: The pace picks up

I really enjoyed this book, particularly the parts where Burton's manuscript is translated. The Jack the Ripper angle was intriguing-- this author seems to be tying together just about everything from Jack to vampires, to aliens. I also like his Atlantis series under the Donegan name. I do wonder, though, about how this will all shake out, particularly the whole immortality angle.
