I would suggest a good library of exposes of business fraud. Equity Funding, Homestake Oil, Penn Square Bank, Dreyfuss Securities, Enron, Worldcom.
Not to sure, when I got my MBA, one of our requirements was to take a semi-ethics class, and study some of the fraud and unethical cases of years past (including enron and woldcom).
At the end of it, the professor was asking us what we learned, I (jokingly) noted I had now learned several various ways to commit money laundering, embezzlement, fraud, how to cover up bribary, and various ways to commit unethical, if not outright illegal acts, and by not making the same mistakes as others, not get caught.
I was kidding, but the good old prof, actually said it was concerning him, that he hadn't realized, he could be making a better criminal for tomorrow.
