Circle Of Greed, by Ron Diesel

Circle of greed is a story set in Australia of the perfect casino robbery executed by three professional thieves that quickly turns into a major disaster because of the greed of the participants, the story moves through various plots and counter plots.
The idea for this story came to me while playing roulette in a casino, every now and again a casino employee came to the table with two guards and took away the money the punters had exchanged for chips, the croupier pushed the money through a slot in the table top and the cash fell into a box below the table.
