In the mid 1990s, at a vast hotel complex on a private Florida beach, dozens of bankers from JP Morgan gathered for what was to become a legendary off-site meeting. It was a wild weekend. But among the drinking, nightclubbing and fist-fights lay a more serious purpose - to assess the possibility of building a business around the new-fangled concepts of credit derivatives.

The group at the heart of this revolution was an intense team, made up of individuals with a supreme sense of loyalty to each other and to the bank - for years, nothing could break them apart.
