Moves/ideas for a 'dark' interpretive dance?

Never done an interpretive dance kinda of thing and when I did dancing I got a D... Anyways for English, for our individual novel studies we have to through dance portray an event in a novel and the event I'm doing is from The Way Of Shadows by Brent Weeks where the main character (who is only a child at this point), living in the slums, has his friend's (a young girl - 8 yrs about and is mute) face completely mutilated by the 'guild' leader. The main character then finds the girl. So its not exactly a happy scene. So pretty much I have to go through the dramatic cutting + reaction + feeling of the characters I think. Obviously I'm not actually going to mutilate anyone during the dance and have already thought of some ideas of how to portray this but as I'm not a dancer and am just doing this because we have to I thought I'd have some fun, its English after all, we aren't getting marked on our dancing capability though I want to make this as good as I can and think I'll enjoy doing something so over the top. Any ideas for moves or costume ideas would be great as well as music to accompany it. The moves don't even have to be THAT meaningful (thought the more mysteriously awesome they are the better) - I can just have to put the meaning in them later :D All over the top ideas are good - it's meant to be a serious event, but that doesn't mean the DANCE can't be funny to watch.
