Carlos Lehder Rivas, kingpin of Colombia's most murderous cocaine empire. A powerful international businessman and self-proclaimed revolutionary. He made the mistake that would end his career: He invited an American professor to be his guest on the island of Norman's Cay... Richard Novak, father of five and lover of the sea, came to Norman's Cay to study the hammer-head shark up close. But the college professor soon found himself locked in combat with a global archcriminal who had stared down the police agencies of major superpowers... Norman's Cay, island paradise of the Bahamas, that, thanks to Carlos Lehder, became the nerve center of the Medellin Cartel, complete with gun towers and a DC-3 landing strip. Here is the amazing true story of how Richard Novak helped bring Lehder to his downfall-armed only with a .357 Magnum, his underwater sabotage skills, and the lone courage of his convictions.
