Every time you think you know who it is, you become unsure again. A number of the possible people you will think is guilty, more than once. And then you will go back to being unsure if you are right.

Excellent, excellent, excellent! The movie wasn't on my radar as high on the must-watch list but none the less maybe worthy of a view. This movie was well done, acting was stellar and the plot was twisting all the time. Just when you think you've got it figured out another twist. Highly recommend this movie.

British horror can be stiff and underwhelming. This one is incredibly smart. The cast is terrific.

This movie is a great period piece of the Nineteenth Century in London. Good sets and interesting plot.

Not for everyone but interesting twists and more imaginative than Jack the Ripper.
