The Panther by Nelson Demille

Anti-Terrorist Task Force agent John Corey and his wife, FBI agent Kate Mayfield, have been posted overseas to Sana'a, Yemen-one of the most dangerous places in the Middle East. While there, they will be working with a small team to track down one of the masterminds behind the USS Cole bombing: a high-ranking Al Qaeda operative known as The Panther. Ruthless and elusive, he's wanted for multiple terrorist acts and murders-and the U.S. government is determined to bring him down, no matter the cost. As latecomers to a deadly game, John and Kate don't know the rules, the players, or the score. What they do know is that there is more to their assignment than meets the eye-and that the hunters are about to become the hunted.

Filled with breathtaking plot turns and told in John Corey's inimitable voice, The Panther is a brilliant depiction of one of the most treacherous countries in the world and raises disturbing questions about whether we can ever know who our enemies - or our allies - really are.
