Query: Tough Read. Hard to understand.

I bought this book because it sounded very interesting. A cop living his life in depravity while still maintaining his career. I know the author had written Trainspotting and I enjoyed that movie. But thats the problem. If I would have read Trainspotting I probably would have put the book down after 20 pages like I did with Filth. Nothing against the author or the book itself I just could not understand there use of the english language. For those who have seen Trainspotting try to imagine reading it instead of watching it and try to understand the slang words and that cockney dialect in written form. I just couldn't read a novel that I couldn't understand. Filth does sound like it would make a good movie though.
