Carlos Lehder Rivas, kingpin of Colombia's most murderous cocaine empire, invited an American professor to Norman's Cay to study the hammerhead shark up close--and the two ended up in mortal combat. Professor Richard Novak, father of five, armed only with a .357 Magnum, his underwater sabotage skills, and the lone courage of his convictions, brought Carlos to his downfall. Photographs.
