The Mordida Man - Ross Thomas

Only one man can save the president's kidnapped brother in this propulsive thriller from the author "without peer in American suspense" (Los Angeles Times).
American agents abduct a high-profile terrorist in broad daylight on the streets of London, subduing him with a tranquilizer. He dies a few hours later on a flight back to Washington, DC, and the body is dropped into the ocean. Hours later, the President's brother—a political powerhouse in his own right—boards a plane to Las Vegas that doesn't land in Nevada. Libyan radicals are at the controls, and he is their prisoner. The only man who can save him is Chubb Dunjee. A former United Nations operative with skills in every aspect of political negotiation, Chubb became famous for solving problems with well-placed bribes. Saving the President's brother should be no trouble for him. But the Libyans don't want a bribe. They want blood.
