Les Miserables: Complete and Unabridged

Les Miserables: Complete and Unabridged - Finally Finished!!! Whew. This is a really good book, but Hugo does go off into tangents. What was he thinking when he wrote about the street slang for example? He goes off on these tangents and I have only found one or two of them to contribute anything to the main stories of Jean Valjean, Cosette and Marius.
