drd: the more important question is, did you see the Wire? ;-) I'm a financial investigator at the police, a bit like Lester Freamon in that show...
Used to work at two of the big 4 accounting firms, doing tax returns and tax accounting mostly for international companies using the Netherlands as a tax haven :-( but i always saw it as a way of gaining the experience necessary for getting my dream job, which is what i have now.
I investigate everything from bankruptcy fraud to laundered drug money and from calculating the proceeds of environmental crime to financial crumbs that might lead us to a kidnapper... Occasionally a murder case to see if there is a financial motive, to find a suspects location, or to confiscate money to be given to the victims relatives. It's a lot of numbers and spreadsheets and legal documentd, in short the things that most people find dreadfully boring... but first of all, even when I take a shower I tend to think in numbers or in abstract concepts applying to whatever situation is on my mind, and secondly, the subject matter just makes it absolutely thrilling. So I'm having a blast!
