This just didn't hold up to all the hype for me. I had trouble with the main character in the 1700s because she really was helping kill people without too much examination of the reasons. AND I really didn't like the current times character who miraculously finds a vial after 5 minutes of mudlarking, finds an undiscovered building in the middle of London, links it all to documents in the British Museum.... I just didn't buy it.
