Hard to get into. Not my favorite. Never even finished it.
I liked this book as it covered Jack the Ripper from a quasi sci-fi perspective and combined the mystery of who the murderer was with how the detectives came back through time to follow Jack's victims around until they caught him. Okay, maybe I over simplified a bit but it was still a quick book.
Interesting take on Jack The Ripper. Two people travel back in time to the period of The Ripper, chaising another individual who they must bring back to the present.
