It's the story of Nick Leeson, the guy who was in large part responsible for the collapse of Barings Bank in 1995. Barings was founded in 1762 and helped finance the Louisiana Purchase in 1802. It had been, until it's demise, a very respectable bank.
Although Leeson seems to get branded as the villain acting alone, many in the bank either deliberately or accidentally seemed to provide no oversight. That lack of oversight, IMHO, contributed more than a lot to Barings collapse.
Leeson wrote two books and has done the speaking circuit--showing that crime can pay.
The NY Times, in describing the first book, Rogue Trader, said "This is a dreary book, written by a young man very taken with himself, but it ought to be read by banking managers and auditors everywhere."
