An abbreviated version of Les Miserables is a crime. Those chapters on the sewer system of Paris were very interesting (seriously :D).

I read a free English translation of Les Mis from Amazon and it was pretty good. Not sure which translation it was (there's been a few different English ones) but I believe it had all the sewer systems, convents, and barricade discussions that the original had. :D Thumbs up for wanting to read the longer version!

Haven't read The Man who Laughs Yet (added to my to read shelf on Goodreads). Toilers of the Sea was awesome heartbreaking though and Ninety-Three was pretty good. Hugo did love tragedies...
